Description
Buchnera americana is a hispid to pilose perennial with erect, simple stems growing up to 4-8 dm tall. The entire plant turns black when dried. The leaves are opposite, elliptic to ovate-lanceolate in shape. The leaves are entire or irregularly serrate or crenulate, sessile. The inflorescence is an open spike, the flower are in the axils of opposite bracts and subtended by 2 bractlets. The calyx tube is cylindrical, grows up to 3.5-5 mm long, the lobes 5, lanceolate in shape, slightly unequal, up to 1 mm or less long. The corolla is purple or white in color, subsalverform, weakly zygomorphic, lobes 5, shorter than the calyx tube. Up to 4 fertile stamens are present with anthers with only a single sac. The capsule is ovoid or pyriform, grows up to 5-6 mm long and is loculicidal in shape.[2]
Specifically, for Buchnera americana, they have noticeable 3-veined leaves that are ovate-lanceolate in shape. The corolla is purple in color. The calyx tube is 10-12 mm long, the lobes are 5-8 mm long. Flowers from July to September.[2]
Distribution
It is the most widely distributed North American Buchnera species, and is found historically in 24 states.[3]
Ecology
B. americana is a hemiparasitic species, meaning that it gets nourishment from the roots of other plants, but also produces its own nourishment through photosynthesis, and can survive with out a host. Hemiparasitic plants have modified roots called haustoria, that allow it to attach to a host plant and obtain nutrients. Host for this species include: Pinus clausa, Pinus echinata, Pinus elliottii, Pinus palustris, Pinus strobes, Pinus taeda, Celtis laevigata, Fraxinus pensylvanica, Liquidambar styraciflua, Liriodendron tulipifera, Nyssa aquatica, Nyssa sylvatica, Platanus occidentalis, Populus deltoids, Quercus alba, Quercus falcata, and Quercus shumardii[4]. However, one study found that B. americana can mature without ever attaching to a host plant.[5]
Habitat
B. americana is found in moist environments near ponds and low brackish marshes, at the edges of hammocks, and in hillside bogs. However, it can also appear in drier situations like savannas, pine flatwoods, dry open woods, hillside prairies, open prairies, coastal dunes, and shallow, grassy depressions. In addition, it can be found in disturbed areas such as roadsides, ditches, sandy fields, open pastures, and clearings that have become weedy. This species prefers open, sunny conditions, but occurs in a range of soil types, from dry loamy sand, to moist black sandy peat, seasonally damp areas, acidic sandy soils, and clay soils.[6]
Associated species includes slash pine, longleaf pine, saw palmetto, cypress, Hypericum opacum, Eryngium integrifolium, Xyris elliottii, Habenaria integra, Polygala ramosa, Polygala lutea, Ctenium aromaticus, Hibiscus aculeatus, Lobelia, Baccharis, Myrica, Erigeron strigosus, Polypremum procumbens, and others.[6]
Phenology
B. americana has been observed flowering as early as January, through October with peak inflorescence in April and May.[7] Fruiting has been observed February through November.[6]
Seed bank and germination
Seeds can remain viable in the soil for 3 years. Requires light for germination.[8]
Fire ecology
Fire kills plants that made shade out B. americana.
Pollination and use by animals
Buchnera americana is pollinated by butterflies.[8]
Conservation, cultivation, and restoration
It is listed as endangered by the Committee on the Status of Endangered Wildlife in Canada for Ontario, the Indiana Department of Natural Resources, the Illinois Endangered Species Protection Board, the Maryland Department of Natural Resources, and the New York Division of Land and Forests.[4][9][10] B. americana is also listed as threatened by the Ohio Department of Natural Resources, as possibly extirpated by the Michigan Department of Natural Resources, and as extirpated by the Maryland Department of Natural Resources and the Pennsylvania Department of Conservation and Natural Resources.[10] While B. americana is considered to be an abundant weed on roadsides in central and southern Florida, it was noted that it does not seem to do any damage.[11] This species is recommended for natural landscapes and habitat restorations, also recommended for butterfly gardens. Prefers moist to wet, well-drained to poorly drained sandy or limestone soils and does not tolerate long term flooding.[12]
