Discussion | Hypericum buckleyi is found throughout the southern Appalachian Mountains. The decumbent habit and persistent sepals and stamens distinguish Hypericum buckleyi from its nearest relative, H. prolificum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The thick, often spongy, bark, relatively long axillary leaf clusters, paired leaf grooves flanking the midrib abaxially, broader inflorescence, and broader capsules distinguish Hypericum fasciculatum (and H. chapmanii) from H. nitidum and its relatives. Hypericum aspalathoides Willdenow is an illegitimate name for H. fasciculatum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
