Bloodroot, Sanguinaria canadensis

This common member of the Poppy family nearly always eludes my camera. It flowers briefly and the tepals fall of early and easily. Today I was fortunate to find a few colonies in good shape for photos. With this post I would like to honor the memory of my 4th grade teacher, Melvin Gutzler, who took my class to the woods and introduced us to the spring ephemerals. This simple and inexpensive field trip stirred in me a curious fascination about wild plants, which continues over four decades later. As a student of the flora, I have spent many, many delightful hours in quality natural areas. Thank you, Mr. Gutzler!!

Plant Quiz Solved! Ranunculus fascicularis, Early Buttercup

Good call, Phytophactor and Scott. It is "ranunculaceous," and Scott is correct, it is Ranunculus fascicularis. This plant is especially at home on dry, sloping clay soil under a thin growth of oak and hickory. The specific epithet "fascicularis" refers to something being "bunched." The other day I saw this plant with its fascicled (or bunched) roots exposed from erosion. Amazing!

This plant always interests me with its change in appearance as it develops. Below are photos from last year showing how the petioles elongate and the plant thins out as the season progresses.

Hepatica acutiloba, Sharp-Lobed Hepatica

Early spring on wooded slopes can be delightful when Hepatica starts emerging. In northeast Indiana, it is flowering abundantly on rich slopes in the Edna Spurgeon Nature Preserve. Normally I take a series of pictures using a variety of camera settings. Several examples are included here; the differences between the latter two are subtle. Life is good, and spring is wonderful!

Outwitting the Wily Orchids

Dan, Dan, the orchid man McDowell, my mentor for all things botanical, is fond of saying, "Peter, the neat thing about orchids is they can hide, but they can't run." But knowing this to be true is not always helpful in finding the less showy members of the orchid family.

There are three woodland species of orchids here in Indiana that can neither hide, nor run, during the winter months. The green over-wintering leaves are easy to spot among the decaying leaf litter on the forest floor. Find those leaves now before the green-up, mark their location with a GPS and return later when they are in bloom, and likely to be hidden by closely growing associates.

(1) Aplectrum hyemale
Common name: puttyroot, Adam-and-Eve orchid

(2) Tipularia discolor
Common name: crane-fly orchid

(3) Goodyera pubescens
Common name: downy rattlesnake plantain

Aplectrum hyemale sends up a single leaf in late September which is usually shed when the flower stalk is present in May. It is common to find an abundance of leaves at a winter location only to find a few flowering stalks when you return in the spring.




This is the rarer greenish form of Aplectrum hyemale forma pallidum which grows at a site in LaPorte County.


--------------------------------------------------------------------------------------------------------------

Tipularia discolor, like the puttyroot, Aplectrum hyemale, produces a single leaf in September which is absent during flowering. I recently counted 22 leaves of this species at a LaPorte County site in April, but found only one flowering stalk when I returned in August.


Note the purple underside of the leaf of Tipularia discolor.



----------------------------------------------------------------------------------------------------------------

Unlike the preceding two species, the strikingly patterned foliage of Goodyera pubescens can be found throughout the year, and is present during flowering in July and August.

Pondberry pursuits

Pondberry (Lindera melissifolia) is a federally endangered shrub, and Missouri has just one population on the Arkansas border at Sand Pond Conservation Area (and adjacent TNC property). I got to see it in bloom yesterday.

The area was hard hit by a severe ice storm in January of 2009. The largest overstory trees came crashing down, and the remainder were stripped of all their branches. You can see a large canopy gap in the photo below.

The pondberry was thriving in ankle-deep water at the base of this behemouth blown-down tree. See the person in the background for scale.

The pondberry appears to do best with specific hydrology: it tolerates being innundated with water, but apparently doesn't want water that is too deep (you can see here that it is growing only on the edges of this deeper pond. The water levels are most likely lower than usual this year: southern MO has had a relatively dry winter/spring). In other areas of the preserve, it is growing in somewhat drier areas. Although the pondberry has responded well to the canopy opening created by the ice storm, it is being outcompeted in the drier locations by greenbriar, poison ivy and other shrubs and vines which have also benefitted from the greater light levels. Pondberry seems to thrive only where it is just wet enough to keep the competition down.

The Mysterious Trillium nivale

Even in Indiana, March isn't too early for some good botany. Last weekend, Lee Casebere and I headed to southeastern Indiana in search of the stunning and pre-spring blooming Trillium nivale. The specific epithet nivale means "of the snow," leading to the common name Snow Trillium for this species, which is sometimes seen blooming when snow is covering the ground. According to Wildflowers of South West Indiana, Trillium nivale was in bloom as early as March 3 this year!


There it is, right at home growing from a crevice in a moss-covered limestone outcropping. This is a tough plant, for sure, considering that it can withstand being frozen every night, and that it grows on nearly bare rock. These conditions are exactly what Trillium nivale needs, as it doesn't do well when in competition with other vegetation. Another habitat in which this little wonder is found is in gravelly-sandy alkaline floodplains, where the periodic disturbance of overbank flooding creates conditions where not many plants will grow and Trillium nivale can benefit from the lack of competition.


Trillium nivale has a somewhat spotty distribution throughout the Midwest, Great Lakes, and New England states. Its strongholds appear to be Iowa, Illinois, and Indiana, where it is locally abundant. Even so, it is often difficult to predict exactly where you will find Trillium nivale; you can often find it growing abundantly in one spot, yet not find a single plant in the exact same habitat a few hundred feet away. I hope you are all lucky enough to find Snow Trillium in the short time that it blooms, from March to early April.

A Fruit Salad of Mosses (apples and pears, that is)

In early spring botanists get itchy feet and head out to find the first blooms of the season. Unfortunately, they are initially met with standard fare such as Erigenia bulbosa, Lamium amplexicaule or Houstonia minima. If you find yourself in this situation and since you are peering intently at the ground anyway, you may as well keep a humble eye out for a bryophyte or two; no doubt you will see many.

Here are two of the more easily identified mosses you could encounter. Though not a purely unique character, both species have rather spherical capsules. The first is Physcomitrium pyriforme.

In my experience, this moss is usually found in rather disturbed or recently burned areas with full sun and is readily identified by the tongue-like leaves with apiculate tips and the pear-shaped (broadly obovate) capsules; a character from which the species epithet is derived (Pyrus being the genus of pears). The second species is Bartramia pomiforme.

This is a species of higher floristic quality. It is an acidophile and is pretty much restricted to wet sandstone ledges, bluffs and terraces in shaded forests; the kind of places you expect to see an abundance of mosses. With its narrow pointed leaves, yellow-green coloration and soft texture there are few mosses with which to confuse it. The nearly perfect spheres that are the capsules pretty much seal the deal. Though I don't like to perpetuate the use of common names, this one is apt. It is called Apple Moss which jives well with the specific epithet (a pome being the fruit type of the apple). At maturity the capsules turn reddish-brown and then look so much like apples that Eve herself would not be able to resist them.

And if you have no taste for mosses, fruity or otherwise, it won't be long before the woods are once again heavy with tracheophyte greenery and the floral distractions there unto.

An Early Sign of Spring, Corylus americana

I was reading Shrubs of Indiana by Weeks and Parker when I realized that I had never taken the time to find and appreciate the female flowers of American Hazelnut. I found a nice thicket while hiking at Spring Mill State Park, in Lawrence County, Indiana. I like the female flowers, maybe because I had to look for them. Plants are monecious, so you can find both flowers on the same plant.

The male flowers are easy to see from a distance, as they are several inches long, numerous, and hang out in the open.

First Flower of 2011

Seems a little early for a "first flower of the year" post, doesn't it?


Not when that first flower is the winter- to spring-blooming Hamamelis vernalis, Ozark Witchhazel!

A Few Slide Show Rejects

Our annual botany slide show will be held next weekend; it really snuck up on me this year. This year, my slide show will highlight the trip that Justin, Brad, Doug, and I took to the Ozarks and Ouachitas in April 2010. As I did last year, I wanted to post a few of the reject photos that didn't make my slide show.

This is Silene virginica, a plant in the family Caryophyllaceae that is found throughout the eastern half of the United States. We found this plant in a dry, rocky woodland at Spurgeon Hollow preserve in Missouri.

Collinsia violacea is known from seven states in the southcentral portion of the country. We saw this member of the Scrophulariaceae at Middle Fork Barrens in Arkansas.

This interesting little mint (Lamiaceae) is Scutellaria parvula var. australis, known from much of the southeastern United States. We first saw this species at Dry Lost Creek Preserve, and later at Camp Road Shale Barrens, both in Arkansas.

Florida Palmettos

To someone from the Great Lakes region, botanizing in Florida in March can be a bit difficult. It seems like nearly all of the trees have entire-margined, thick-textured, glossy green ovate leaves. Similarly, many of the palms (Arecaceae) look very similar; specifially, the palmettos (Serenoa, Sabal), with palmate to costapalmate leaf blades, look nearly identical at first glance. Below, I will summarize the differences between the species in this latter group that occur in Florida.


Serenoa repens (Saw Palmetto) tends to have leaf blades that are yellowish-green (see photograph above), whereas the leaves of Sabal palmetto (Cabbage Palmetto) are more blue-green (see photograph below). In addition, Serenoa repens has a shrubby growth form; Sabal palmetto usually becomes a tree, though it sometimes has no aboveground trunk.


Looking at the leaves up-close, it is even easier to distinguish between Serenoa repens and Sabal palmetto.


In Serenoa repens (above), the petiole has serrate margins (that will cut through your skin, trust me), thus the common name Saw Palmetto. The petioles of Sabal palmetto are entire. Also, take a look at the apex of the leaf rachis. In Serenoa repens, the apex is blunt, whereas in Sabal palmetto, the rachis is spear shaped.


Serenoa repens grows in pine woodlands, scrub, and mesic hammocks; Sabal palmetto, Florida's state tree, can be found in pine woodlands, hammocks, and on river banks. The two are sometimes found growing together, as seen below.


That takes care of the two most common Florida palmettos. The other two, both in the genus Sabal, also have petioles without serrate margins.

Sabal minor (Dwarf Palmetto) can look similar to Sabal palmetto, but as its common name suggests it is a much shorter plant. Found in moist soils and wetlands, the trunk of Sabal minor typically remains underground. In addition, the fruits of Sabal minor are a bit smaller than those of Sabal palmetto.

Sabal etonia (Scrub Palmetto), a Florida endemic, is found in dry, sandy soils in scrub habitat. Its leaves are smaller and have narrower segments than either Sabal palmetto or Sabal minor. Like Sabal minor, the trunk is subterranean, so Sabal etonia doesn't grow more than 3-6' tall.

That should do it. Should you find yourself in the midst of Florida palmettos, hopefully this summary will help you to determine which species you are seeing.
