diameter, glabrous, smooth, those of the stem similar to the 
basal ones, usually 2 or 3, the uppermost passing into bracts. 
Panicles rather narrow, 10 to 25 cm long, the primary branches 
few, distant, 6 cm long or less, ascending. Spikelets oblong- 
lanceolate, compressed, brown, 5 mm long, in pairs from sheath- 
ing bracts, their pedicels 2 to 5 mm long, the bracts 3 to 5 mm 
long or longer, long-acuminate. Empty glumes 2, subsimilar, 
lanceolate, acuminate, about 3 mm long, the second one some- 
what keeled and wider at the base than the first. Third and 
usually the fourth glume each with a perfect flower, the glumes 
about 3.5 mm long, 2 mm wide at the base, acuminate, fifth and 
sixth glumes about 3 mm long, each, or only the fifth, with a 
male flower. Ovary small, ovoid; style 1 to 2 mm long, the 
arms 38, slender, 3mm long. Stamens 3; filaments 2.5 mm long; 
anthers linear-oblong, 2.5 mm long, apiculate. Young nutlet 
z globose, sessile, apex rounded, not at all beaked, about 1 mm 
in diameter, somewhat verruculose. 
R. C. McGregor 492, hills southeast of Piti, altitude about 300 meters. 
A species manifestly allied to the Philippine Cladium filiforme Merr., but 
larger, with larger panicles, quite glabrous leaves which are not scabrid, 
and straight, not at all falcate spikelets.

The specimens greatly resemble certain specimens in the Herbarium of 
the Bureau of Science determined as Eleocharis atropurpurea, but in essen- 
tial characters agree with the descriptions of E. capitata. There is very 
little doubt but that it is the same species that was reported from Guam 
by Presl” as Eleocharis atropurpurea.
