309. S. LEPTOSTACHYA A. Br. in Crypt. Nov. Gran. 873. — Stems 

 slender, suberect, with root-fibres from the lower half, bisulcate 

 down the face, closely pinnate, the branches erecto-patent, the 

 lower copiously compound. Leaves of the lower plane contiguous 

 on the branchlets, spaced on the main stem, ovate, acute, l-12th to 

 l-8th in. long, bright green, firmer in texture than in 5'. Lijchnnchus, 

 nearly equal- sided, not ciliated, a little dilated, and slightly imbri- 

 cated over the stem on the upper side at the base ; leaves of the 

 upper plane one-third as long, oblong-cuspidate. Spikes resupinate, 

 reaching an inch or more in length, l-12th in. diam. ; bracts of the 

 upper plane lanceolate-acuminate, erecto-patent ; of the lower plane 

 ovate-lanceolate, ascending, strongly keeled.

310. S. Karsteniana A. Br. in Crypt. Nov. Gran. 372. — Stems 

 about a foot long, erect from a decumbent base, bisulcate down the 

 face, copiously pinnate, the short erecto-patent branches sparingly 

 compound. Leaves of the lower plane ovate, acute, dark green, 

 subdiaphanous, very unequal-sided, denticulate on the upper mar- 

 gin, much produced on the upper side at the base, and imbricated 

 over the stem ; leaves of the upper plane one-third as long, ovate-

811. S. ramosissima, n. sp. — Stems erect, ^ ft. long, simple 

 near the base, copiously j)innate above it, the lower branches 

 decompound. Leaves of the lower plane spaced even on the 

 branchlets, ascending, oblong-lanceolate or lanceolate, acute, a line 

 long, bright green, membranous, nearly equal-sided, serrulate on 

 both sides, rounded, and a little imbricated over the stem on the 

 upper side at the base ; leaves of the upper plane half as long, 

 ovate, with a large cusp. Spikes very copious, resupinate, \-\ in. 

 long, l-12th to l-8th in. diam. ; bracts very dimorphous, those of 

 the upper plane lanceolate, ascending, rather squarrose ; those of 

 the lower plane ovate-lanceolate, ascending.
