Coll. No. 2180, 23 Jul 2019: Nearby collections (15 km., SEINet, 29 Jan 2020) are of Apocynum cannabinum L. and A. androsaemifolium L. I applied the hybrid name (A. ×floribundum Greene) to this collection because the leaves are spreading to ascending, not drooping, and the corolla lobes are more spreading, not reflexed. Also of note, the corolla is more than twice the calyx.
