A simple key from Dr. Almeida’s flora Vol IV-B pg 350:
1. Unarmed; leaves 2.5-8cm long —- Flueggea obovata (now Flueggea virosa)
2. Spinous; leaves rarely exceeding 2.5 cm long — Flueggea leucopyrus .
As per efi thread :
Duthie in his document Flora of Upper Gangetic Plains has also mentioned these two species and differentiate them as- Unarmed; leaves 1-3 inches long ……. F. microcarpa (now Flueggea virosa)
Spinous; leaves rarely exceeding 1 inch long ……. F.leucopyrus
He has mentioned its (F.microcarpa) distribution in Bengal also.
Spines in F.leucopyrus are not distributed all along the branch but slender angular branchlets ends in a sharp spine; . As per efi thread: F.virosa has small prickles, but it not prominent in its life cycle, prominent in leucopyrus. .
