S. TRACHYPHYLLUS, Mont. Rotting wood, Sandakan (No. 34). Mr. Bin- 
stead's plant agrees in everything with specimens of Montagne's at Kew, 
except that the nerve is more spiculose at the back, for some distance down. 
I have examined the original of 5. gracilis, Mitt. (Tristan d'Acunha, leg. 
Milne) at Kew, and find it to be certainly identical with S. trachyphyllus. 
The back of the nerve is not smooth, as stated, but variously spiculose-hispid 
near the extreme tip, though some leaves have the певуе actually smooth 
throughout. In fact, precisely the same degree of variation obtains as in 
Montagne's Singapore S. trachyphyllus in Herb. Kew.

Hab. Jungle, Sandakan, 4 Apr. 1913, c.fr. (No. 30). 
Structurally this plant is nearly related to 5. trachyphyllus, but the white 
colour, the narrower leaves, subtubulose above even after moistening, with 
the lamina considerably longer in proportion to the base, give it a very
