The genus Calopogon is derived from the Greek words meaning beautiful beard.[4]
Description
C. tuberosus is a perennial forb/herb in the Orchidaceae family native to North America.[1] The prominent hairs, called the Beard, on the lip of the petal as well as the sweet fragrance from the flower are the main identifying features.[4] The plant originates from a small ovoid corm that has many fibrous roots. Leaves 1 to rarely 2, basal and grass-like, linear, and ribbed. Flower inflorescence a loose terminal raceme between 1 to 8 blossoms, buds sickle-shaped, bracts ovate-lanceolate and acuminate. Flower a deep magenta or rose-purple color, and middle sepal oblong-elliptic and acute. Lip uppermost, linear, and dilate into rounded or triangular apex.[5] The corolla has been observed to vary in color from purple to light rose pink.[6]
Distribution
Found along the east coast of the United States and Canada into the center of North America, the C. tuberosus is common in savannas, sandhill seeps, and in bogs within mountain regions. C. tuberosus var. simpsonii can be found in south peninsular Florida, the West Indies, and Cuba.[3]
Ecology
Habitat
C. tuberosus is common in savannas, sandhill seeps, floating peat mats, and other regions during April to September. [3] A variety of other habitats that this orchid can been found include, marl prairies, pine flatwoods, roadsides, fens, and bogs. [7] Specimens of C. tuberosus have been collected from moist loamy sand of savanna like longleaf pine regions, and wet seepage areas. [6]
Associated species: Arnoglossum sp., Lycopodiella sp., Rhynchospora sp., Juncus sp., Utricularia sp., Cliftonia monophylla, Sarracenia leucophylla, Syngonanthus flavidulus, Eriocaulon compressum, Lachnocaulon anceps, Drosera capillaris, and Drosera tracyi.[6]
Phenology
Common bloom time is between March and August.[4] It has been observed to flower in the southeast coastal plain from April to June with peak inflorescence in April.[8]
Seed bank and germination
Generally, warmer temperatures produce more seedling germination for the C. tuberosus with the exception of Michigan where cooler temperatures resulted in more germination. Also, fluctuating temperatures are more beneficial than stagnant temperatures. [9]
Pollination
C. tuberosus does not provide a benefit to pollinators, due to this aspect they use deceit to get pollinators to come. Bees land on fake stamens which causes the structure to collapse and transfer pollen to the bee.[10]
Conservation and Management
C. tuberosus is listed as endangered by the Illinois Department of Natural Resources, the Kentucky State Nature Preserves Commission, and the Maryland Department of Natural Resources. It is also listed as a species of special concern by the Rhode Island Department of Environmental Management, and listed as exploitably vulnerable by the New York Division of Land and Forests.[1]
