This is a distinct species—one of several plants showing 
an indumentum on the under-leaf surface approaching on the 
one hand the Lacteum series, and leading on the other hand 
to the Roxieanum series. In 1914 Mr. Forrest obtained it on 
the Mekong-Salween divide, but only in leaf, which in dried 
specimens was so striking that he took out with him in 1917 4 
specimen of the dried plant for comparison with plants on the 
spot in the hope of rediscovering it. In this he has been entirely 
successful. From north of Atuntzu we now have flowering speci- 
mens. The plant is easily recognised by its lanceolate leaves 
blunt at the base and with greenish or yellowish buff-coloured 
‘under side at first, changing to a cinnamon-rufous colour with age. 
Especially characteristic is the smooth not agglutinate indumen- 
tum, which has a speckled or stippled look. Rh, levistratum is an 
eglandular form, and I find no marks of stickiness anywhere.
