(203) S. maxima, t% A. t>. H., Bull. Btz., 1914, XVI, 53. 

 Shoots of young plants erect from a decumbent base, of adult plants 



springing from a subterete, probably scandent, main stem 5 6 mm. diam. ; 

 main stem sparingly foliate with subisomorphous, ovate, acute, entire leaves; 

 secondary stems articulated at the base, relatively short, 2 2V mm. 

 thick, 3 5-stelical, with the axillary leaves broadly oblong or suborbicular- 

 rhomboidal; pinnae few, lanceolate, 20 30 cm. long, 6 8 cm. broad; 

 pinnulae simple, close, ascending, the central ones 5 6 cm. long, 10 12 

 mm. broad including the lateral leaves. Leaves of the pinnae hetero- 

 morphous; lateral leaves rather close, lanceolate-falcate, bluntish, entire, 

 narrowly pellucid-margined; of the ultimate branchlets 6 6Vz mm. long, 

 2V 3 mm. broad, rotundate or rotundate-cuneate and slightly plicate at 

 the upper base, rather rotundate-truncate at the lower base; intermedial 

 leaves erect, unequal-sided, ovate, subabruptly long-acuminate-cuspidate, 

 entire, pellucid-margined, obliquely rotundate-cuneate at the base; of the 

 branchlets close or imbricate, 3 mm. long. Spikes solitary, IVt 2V* mm. 

 diam.; sporophylla ovate, acuminate, entire, pellucid-margined, at length 

 spreading, the largest nearly 2 mm. long; macrospores whitish or yellowish,

Shoots erect or ascending from a decumbent base, 30 cm. or more 

 long, pinnately compound, the stem 4 5-stelical ; pinnulae rather numerous, 

 at least the lower pinnate ; ultimate branchlets 45 mm. broad including 

 the lateral leaves. Leaves heteromorphous; leaves of the stem remote, 

 rather erect; intermedial leaves lanceolate-oblong, acuminate, 2-auriculate-
