Dear Garg Ji
I am really sorry not to respond your earlier mails, as last 10 days I was
in Darjeeling without electricity, water and of course inside house. I have
arrived Kolkata just now by Darjeeling Express and writing you
I am providing some key to identify this species------
Genus is Osbeckia----correct (as stamen whorls are equal to subequal)---but
in case of Melastoma, stamens whorls are unequal
Now coming to species-----
If Hypanthium (calyx Cup) 4--7 mm long........1. Osbeckia chinensis
2.
O. nutans
If Hypanthium 10--23 mm long:
Lamina 17--25 mm long...............................3. O. capitata
Lamina 40--130 mm long:
Flowers 5-merous.....................................4. O. nepalensis
Flowers 4-merous......................................5. O. stellata
Based on this key, I am sure, the species is Osbeckia nepalensis
Osbeckia nepalensis Hook.f., Exotic Fl.1: t. 31. 1823.
More Field identifying characters:
0.5 to 1 metre tall, erect. Stem 4-angled beset with strigose hairs. Lamina
oblong-lanceolate (commonly) to ovate-lanceolate (rarely). Infl. terminal,
a panicle of cymes, 5--8 cm long. Petals 5, pink, purple to white.
Again, O. nepalensis has 2 varieties based petal colour:---
Petal purely white..........var. albiflora
Petal pink to purple........var. nepalensis
I am sure, the taxon is Osbeckia nepalensis var. nepalensis
Distribution: India, Nepal, Bhutan, SW China, N Myanmar, Thailand, Vietnam
& Laos-----usually between 400 - 1900m altitudes.
But, var albiflora repoted only from Nepal & China between 700--1600 m
altitudes.
Now, I request the collector to match your specimen and identify it.
Regards
Dr. S. Panda
