Stylisma humistrata, also referred to as southern dawnflower, is a species of perennial forb found in North America.[1]
Description
S. humistra is a member of the morning glory family (Convolvulaceae) that may reach a length of 0.5 to 2 meters (approximately 1.64 to 6.56 feet). Due to the nature of its growth patterns, older individuals often form clumps or mats.[2]
The leaves are oblong-elliptic to oblong-lanceolate, ranging in length from 2.5 to 8 centimeters and in width from 1.2 to 3 centimeters.[3] They are subcordate and range from sparsely pubescent to pilose, with stellate or simple trichomes.[2]
Inflorescence occurs from June through September.[4] The corolla is white in color, ranging from 1.5 to 20 millimeters in length.[2]
Distribution and habitat
Within the United States S. humistra is primarily found within the southeast region, its range stretching from Virginia south to Florida and westward to Texas.[5]
It has been observed in habitats such as in sandy barrens, dry pinelands and hammocks, and along coastal dunes.[3][6] This species does not require light for germination.[7]
