Hab. Sandy bank about roots of trees in jungle, Sandakan, 31 Mar. 1913, 
с.Ёг. (No. 26). 
In spite of the somewhat ciliated shoulder of the leaf-base, I think this 
distinet species must be placed in the $ Tristichi rather than the Cavifolii, 
the habit and leaf-arrangement being very nearly that of S. tristichus, from 
which as from its allies our species differs evidently in the armature of the 
leaves, while from ©. Ledruanus, S. spiculosus, ete., it differs at once in the 
robust habit and distant, widely spreading subtristichous leaves. 5. mammil- 
losus, C. Muell., resembles it somewhat in habit, but has the leaf-base densely 
pectinate with long closely-set cilia. 
SYRRHOPODON CILIATUS (Hook.), Schwaegr. Sandakan (No. 25) ; Sekong 
(Nos. 85, 94) ; Sadong, Sarawak, 1900, leg. J. H. Cranston (Nos. 89, 97). 
These all belong to the f. pseudopodianus of Fleischer ; but Mr. Binstead's 
No. 94 shows both fruit and pseudopodia growing closely associated on the 
same tuft, if not actually on the same plant.

Fleischer has pointed out the near relationship of these two species to one 
another. He distinguishes them as follows :— 
S. repens. S. Мат. 
Hyaline border reaching apex. Н. yaline border ceasing at 2 leaf, 
Margin denticulate, almost ciliate. Margin slightly toothed. 
Cells inerassate, usually trans- Cells less incrassate, rarely trans- 
versely oval. versely oval, irregularly rounded. 
The plant from Sadong above has the border highly toothed, the cells 
usually transversely oval; Mr. Binstead's No. 41 has the margin scarcely 
toothed, the cells not transversely oval, the leaves much more opaque ; 
No. 33 is somewhat intermediate in characters between the two. In none of 
them does the border reach the apex. I am strongly of opinion that it is 
impossible to draw any clear line of distinction between the two species.
