ad 2 mm. longae, glumis 2-4 ovatis glabris, 1-2 ram. longis; achaenium
glabruro laeve marginatura sublenticulare oblongo-quadrangulatum
vel cum rostro laevi et inflate ellipsoideum, ad 2.5 mm. longum;
squamellae hypogynae nullae; stylus bifidus, stigmatibus brunneis
ad 2 mm. longis (Fig. 6, m).
Type in herb. Chi. Nat. Hist. Mus., isotype in herb. Iowa State
College, collected in swampy woods, between Esmeralda Savanna
and southeastern base of Cerro Duida, Territorio Federal Amazonas,
alt. 200 m., August 22, 1944, Julian A. Steyermark 57820.
This species differs from all the other known species of the genus
in the narrowness and small size of the inflorescence bracts. With
regard to the small number of pistillate spikelets, this species is
most nearly like E. megalorrhyncha Tutin, but in glabrity and cespitose
habit it is more nearly like E. amazonica C. B. Clarke.

Caulis gracilis ramosus, ad 10 cm. altus; folia linearia acuta
bicarinata sparse pilosa, 8-20 cm. longa et 1.5-2 mm. lata; culmi
floriferi solitarii in axillibus foliorum, 4-8 cm. alti; inflorescentia
capitata multispiculata; bracteae inferiores inflorescentiam subtendentes
ad 2 cm. longae, dense vel sparse pilosae; spiculae
masculae 4-5 mm. longae, ad 1 mm. diam.; glumis vacuis 3-5, lanceolatis
mucronatis glabris vel mucrone sparse pilosis, glumis sta minibus
2-3, lanceolatis acutis hyalinis glabris; antherae 2.75-3 mm.
longae; spiculae foemineae 4-5 mm. longae, glumis 5-8, lanceolatis
acuminato-mucronatis glabris vel mucrone sparse pilosis; achaenium

A member of the subgenus Neocephalocarpus, most closely related
to C. longibracteatus Gilly, but approaching C. lineariifolius Gilly
in length and narrowness of leaves. The several specimens examined
vary considerably in the length to which the branched stem
has developed.
