short (2-3x20-30 mm.), smooth, the upper ancipital and dilated to 5 or 
6 mm. below the nodes. Cataphyls 2-4 pairs, toward the base, scarcely 
tubular. Leaves narrowly oblanceolate, very obtuse, scarcely 1x4 em., 
scarcely nerved, cuneately subpetioled for about 5 mm. Spikes more or 
less clustered, moderate (scarcely 25 mm.), with 3-6 slender joints some- 
what turbinately about 30-flowered when staminate and clavately half as 
many flowered in 6 series when pistillate: peduncle 1-2 mm. long: scales 
scarcely ciliate. Fruit said to be pale yellow, globose, smooth, 2.5-3 mm. 
in diameter.—Plate 109.
