fertile spikes to 40 cm. long, simple or dichotomous, tlie lower sporophylla 

 similar to the higher barren leaves, the following sporophylla passing 

 gradually into the higher which are suberect, triangular-ovate, acuminate, 

 hardly keeled, varying from Vs — 'A as long as the barren leaves. — The 

 specimen occurring in the Paris Herbarium, on which Spring based his 

 diagnosis, may probably be an undeveloped plant, and a plant gathered 

 in Java (by Backer) has the shoots repeatedly dichotomous with numerous 

 (about 40 — 60) ultimate fertile branchlets.

Shoots 1 — 3 times dichotomously branched, about 2Vs — 3 cm. diam. 

 including the leaves. Leaves crowded, spreading, the lower 8-farious, 

 the higher gradually ascending and growing shorter, 4-farious, firm in 

 texture, subulate-lanceolate, straight or falcate, I2V2 — 15 mm. long, I'A 

 mm. broad above the base, entire, acute, the base narrowed, decurrent, 

 the decurrent portion strongly and sharply keeled in dried material. 

 Spikes 5 mm. diam. ; sporophylla suberect, subulate, dilated at the 

 base, the lower passing gradually into the higher barren leaves. — L. 

 epicifolium Desv., from Madagascar, which is probably identical with this, 

 is said to have the keel deeply grooved. — Differs from the intermedial 

 forms between L. hippuris Des-v. and L. squarrosum Forst. by the conspi- 

 cuously prominent decurrent keel.

Shoots robust, pendulous, about 45 — 100 cm. long, the stem 2yj cm. 

 diam. including the leaves, the branches more slender. Leaves crowded, 

 6-farious (arranged in alternate spurious whorls of 3), ascending, glaucous- 

 green, very rigidly coriaceous, acerose, more or less incurved, lanceolate- 

 subulate, 15 — 25 mm. long, 3 — 4 mm. broad near the base, canali- 

 culate above, the edges conspicuously involute (in dried material), the 

 midrib prominent above, grooved beneath, the base rather rounded. Spikes 

 simple or forked, to 60 cm. long, 7V2— I2V2 mm. or more diam. including 

 the sporophylla; sporophylla crowded, ascending, more or less incurved,
