Further exploration of this plant leads me to think that this plant may be
one described in Flora of British India (vol. 5, page 578) as Boehmeria
platyphylla var. scabrella wedd, characterised by leaves rugose above and
short erect subsimple spikes. This plant is treated as B. macrophylla var. *
scabrella* (Wedd.) D G Long,  with Leaf blade 4.5-7(-10) × 2-4(-6) cm,
papery, abaxial surface with reticulate veins strongly raised, adaxial
surface rugose, stiffly hispid, apex gradually acuminate as against
var.*macrophylla
* with Leaf blade 6.5-18 × 3.2-12 cm, often membranous, abaxial surface
appressed strigose, reticulate veins slightly raised, adaxial surface
sparsely strigose, apex long-cuspidate, 1.5-2 cm. Female spikes ± branched,
nodding at apex.

It must be noted that var. *scabrella *together with Boehmeria longispica
which is very similar to this and resembling our plant as seen in the link
below are now considered as synonyms of Boehmeria japonica.

Perhaps the crucial difference between B. macrophylla (uploaded already by
me in separate thread and by Dinesh ji on FOI) has membranous leaves with
long slender branched spikes and our above plant B. japonica characterised
by thicker (papery) leaves, rugose above with raised veins and stiff erect
unbranched spikes.

I think my above plant should be
*Boehmeria japonica* (L.f.) Miq.
syn: B. macrophylla var. scabrella (Wedd.) Long; B. platyphylla var.
scabrella Wedd.; B. longispica Steud.

Please note that B. japonica is a polymorphic species with typical plants
(see Flora China) having upper part of leaf with deep teeth. This would
naturally change with inclusion of above synonyms as per The Plant List.

Your comments please.
