Schwenckia filiformis is a species of flowering plant in the family Solanaceae.[1]
The species was first collected by Swedish botanist, Erik Leonard Ekman[2][1] and later described by German botanist, Ignatz Urban, with the description published in Symbolae Antillanae 9:251 in 1924.[3][1]
Distribution
S. filiformis is indigenous to Cuba, the Cayman Islands and Hispaniola. It grows primarily in seasonally dry tropical biomes.[4][5][6]
Description
The plant is an annual or short-lived subshrub reaching 35–40 cm in length and is completely hairless. Its lower stems become woody and produce numerous thin, thread-like branches. The leaves are sparse and vary in shape along the stem, ranging from elliptical or lance-shaped on the lower parts to very narrow, almost needle-like leaves near the top.
The flowers are borne in small, loosely spaced clusters. The calyx is tubular, while the corolla is pale blue and about 10 mm long, with a narrow cylindrical tube. The plant has two fertile stamens and several reduced sterile stamens. The fruit is a small oval capsule containing tiny brown, finely textured seeds.[7]
