Description
H. cumulicola is a short live perennial herb whose stems die back in winter to non-flowering basal branches [1]. The leaves are needle like and opposite, entire, simple, and gland-dotted. The seeds are pointed, opening into three curved, beaked segments, surrounded by 5 persistent sepals [2]. The yellow flowers are small, bisexual, and arranged in a cyme. It may contain hypericin, which is common of species in this genus [3]. The leaves and flowers are similar to Hypericum gentianoides, but can be differentiated by having a single, winged-angled main stem and lacking a cluster of basal branches [1].
Distribution
It is a federally endangered species due to habitat loss, fragmentation, and fire suppression[2]. It is endemic to the Lake Wales Ridge, with populations occurring only in Polk and Highland counties. However; within these counties, this species occurs in relatively large populations of hundreds or thousands of individuals [3].
Ecology
Habitat
