THE FERN -ALLIES OF THE MALAY PENINSULA. 149 



stem, upper plane large, ovate ciliate with a large cusp. Fruit 

 unknown. 



Selaxgou, Semangkok Pass (Bidl. 12040). 



Allied to Eidleyi. 



4. S. calcarea, n. sp. 



A very small slender creeping plant, branches .5 in. or 

 less. Leaves lower plane distant membranous elliptic blunt 

 base slightly narrowed not umbricating over stem .1 in. long; 

 nerve conspicuous, of the upper plane obliquely ovate longer 

 than broad, short, cuspidate. Spike 1.75 in. long slender, 

 bracts rather long lanceolate acuminate with a setaceous point. 



Bare. Selangoe, Batu Caves (Bidley 8772). 



This is very delicate moss-like plant is remarkable for the 

 length of its spikes which are much longer than the branches. 



5. S. strigosa, Bedd. ined. 



Small prostrate plant growing in masses, stems very 

 slender. Leaves lower plane ovate mucronulate base round, 

 edges ciliate sprinkled all over with short hairs .04 in. Upper 

 plane ovate long acuminate the tip usually recurved, not over- 

 lapping, strigose and ciliate on edge. Spike square .25 in. 

 long. Bracts ovate triangular cuspidate ciliate and strigose. 



Mountain forests.

 Gates 13442, 13446. 



6. S. pinangensis, Spring Mon. ii. 205. Bak. Fern-Allies, p. 67. 



Entirely flat, creeping, stems very slender 1.5 ft. long 

 closely set with leaves, with few short branchlets. Leaves of 

 lower plane close, spreading oblong blunt .1-.12 in. long close- 

 ly set with leaves, with few short branchlets. Leaves of lower 

 plane close spreading oblong blunt .1-.12 in. long membranous 

 equal-sided base rounded both sides imbricate slightly over 

 stem, lower half ciliate. Leaves of upper plane J as long 

 oblique ovate with cusp nearly as long as blade lower ones on 

 stem, orbicular cordate, edge ciliate. Spikes short, square. 

 Bracts ovate, acute, keeled. 



Penang ( Gaudichaud) . 



Distrib. Assam. 



Note. — The only specimen I have seen of the type, the 

 Assam plant is not ciliate at all on the lower plane leaves. It 

 resembles the common cultivated 8. serpens notably in the 

 upper plane leaves on stem and base of branches which are 

 orbicular cordate and ciliate on edge. I suspect it is nothing 

 more than an escaped 8. serpens, a native of the West Indies.
