Boehmeria virgata subsp. macrophylla – False Nettle

Other notes

Other Name Combinations: Boehmeria macrophylla (Wilmort-Dear & Friis 2013; WFO, 2024).

Taxonomic Information:
Wilmot-Dear & Friis (2013) classified Boehmeria virgata into two subspecies: subsp. virgata and subsp. macrophylla. These subspecies have distinct distributions, with subsp. virgata (comprising 4 varieties) predominantly found to the east of Wallace's Line, while subsp. macrophylla (including 10 varieties) is mainly distributed to the west. Despite the recognition of distinct varieties, the presence of intermediate forms and the complex pattern of variation make their identification beyond subspecies rank challenging. Therefore, this page hosts all images belonging to this species from India. The following varieties are found in India:
a) B. virgata var. canescens - Eastern Himalayas: India (Sikkim, Arunachal Pradesh), Nepal, Bhutan
b) B. virgata var. longissima - Southern India (Kerala, Tamil Nadu), Sri Lanka
c) B. virgata var. macrostachya - India, Nepal, Bhutan, Sri Lanka
d) B. virgata var. minuticymosa - Northern India, Nepal, Southeast Asia, South China
e) B. virgata var. rotundifolia - Eastern Himalayas: India (Sikkim), Nepal, Bhutan, Burma; south-western China
f) B. virgata var. scabrella - Eastern and western Himalayas: northern India, Nepal; southern China, Indonesia
