A new entry to the efi.
Sharing some pictures of Leucosceptrum canum Sm. shot at Suire Chaur Gurje Bhanjyang Nepal on 26 January 2016 at 6000 ft.

Wonderful plant, new to me!!

Thanks a lot, …, for the new addition. I have now added it to efi.

Thank you for showing this species. It is an exceptional member in Lamiaceae being a small tree. Nealy all members of Lamiaceae (older concept) are herbaceous. It is known to occur in Uttarakhand but I have not seen it yet.

A shrub around 6 feet tall was located near Gala (Height 8000 feet) Aug 29, 2016.

Could it be Leucosceptrum canum (Lamiaceae).
Pl compare with L.canum in eFI.

Leucosceptrum canum Smith

Interesting suggestion. This is a new plant to me and I could not make any meaningful suggestions. Not found in the NW Himalaya (if your suggestion proves to be correct).

As to Leucosceptrum canum, this is new to me as well. The flowering period (Jan) fits with the images taken in Nepal at similar altitude. ‘Flora of Bhutan’ says shrub or small tree in open jungle and forest margins, mixed broad-leaved forest, sometimes cultivated 600-2300m but flowering period December to February which does not tally with late August in the images taken near Gala.

This species is recorded from Kumaon to Bhutan, Assam to SW China. In Nepal at 1000-2800m. ‘Flora of Kathmandu valley’ says a small tree to 8m, flowers white or pinkish red on shady slopes in Oak forest to 2300m.
But I am in no position to support or question the proposed identification beyond this. Cannot see enough detail of the flowers or leaves to comment further on an unfamiliar plant.
