Appeal Swamp

I spent the day along with Leslie and Will, doing a rare, threatened and endangered plant species survey in Appeal/Lusby, Calvert County, Maryland.  Our study area included a forested swamp (PFO1B), abutting an area of fresh tidal Patuxent River.  We were looking for six specific species, none of which were found (statement of negative finding).  I was hoping to photograph Grass-of-Parnassus, as it is known in the area, but was not to be the case.

Tapered Rosette Grass

Tapered Rosette Grass (Dichanthelium acuminatum), which has just recently dropped its seeds.

Water Parsnip

Water Parsnip Hemlock (Sium suave).

Walking Stick Insect

Walking Stick (Carausius morosus), a large insect, crawls on Will’s tee-shirt, working his way up to his face.

Shrubby Bushclover

Shrubby Bushclover (Lespedeza bicolor). 

Rough Buttonweed II

Rough Buttonweed (Diodia teres), not be be confused with the larger, all-white and fuzzy, Larger Buttonweed (Diodia virginiana).

Possum Haw

Possumhaw Viburnum, (Viburnum nudum), whose berries can turn red, white and blue!


Persimmon (Diospyros virginiana) already beginning to color, which seems a little early to me.  Is autumn starting?


Sweet Pepperbush (Clethra alnifolia).  I had to search dozens of shrubs to find this one late bloom, which had a swallowtail feeding on it.


Post-flowering Maleberry (Lyonia ligustrina). 

Longleaf Ground-Cherry

Long-Leaf Ground Cherry (Physalis longifolia).

Forked Bluecurls III

Forked Blue Curls (Trichostema dichotomum). 

Fence Lizard II

Eastern Fence Lizard (Sceloporus undulatus).  I was able to get several great, close-up photos, as this fence lizard stayed in place for a few seconds before scampering up the tree.

False Dandelion

False Dandelion, also known as Carolina Chicory (Pyrrhopappus carolinianus).


I saw these two plants together at the edge of a sunny field opening, along the fringe of the forested marsh.  I knew the on darker yellow plant was a hawkweed, and based at looking at the basal leaves, it was a Large Mouse-Ear Hawkweed (Hieracium flagellare).  The smaller pale yellow flowers mixed with the hawkweed, I thought may have been skeletonweed, but looked slightly different.  I took a cutting and several photos, and had to key this plant at home, and which turned out to be the false dandelion.  I could see why some people would call it chicory, as the flowers look similar, but not blue.


American Bugle (Ajuga reptans), not to be confused with the much more common wetland bugleweed (Lycopus).

On the day we documented 162 plant species in the forested wetland marsh.  Other observed flowering plants included false daisy (Eclipta prostrata), lizard’s tail, late flowering thoroughwort (Eupatorium serotinum), which was very common in the upland margin fields, marsh St. John’swort, showy tick tre-foil and climbing hempweed.

Great day in the field, but very hot and humid.
