first glume is oblong or ovate, flat, smooth, coriaceous, pectinately margined with upcurved spines. The second glume is oblong-lanceolate, acute and 3-nerved. The third glume is hyaline, obtuse, paleate and male. The fourth glume is smaller, hyaline, oblong, obtuse, 1-nerved, paleate, bisexual or female. Lodicules are truncate and slightly oblique. Stamens are three with long anthers. Styles are two with feathery stigmas. The grain is oval, plano-convex. =Eremochloa muricata, _Hack._= This is a perennial tufted grass with a woody creeping root-stock. Stems are erect or ascending, slender, strongly compressed, lower parts completely covered by rigid equitant leaves, 6 to 18 inches long or more. The _leaf-sheath_ is broad, flat, much compressed, glabrous and keeled. The _ligule_ is a short membrane. _Nodes_ are glabrous. The _leaf-blade_ is linear, glabrous on both sides, 2 to 6 inches long and 3/16 to 1/4 inch broad, with a rounded tip and two unequal lobes. The _spike_ is solitary, up to 6 inches (or more) in length, joints of the rachis 1/3 to 1/2 the length of the spikelets. _Spikelets_ are solitary, sessile, compressed, secund. The _sessile spikelets_ are 3/16 to 1/6 inch, and consist of four spikelets. The _first glume_ is oblong-lanceolate, dorsally slightly convex, smooth, coriaceous, 7- to 9-nerved, and with pectinate margins consisting of long, spreading, upcurved spines and at the top with subquadrate wings on each side reaching beyond the acute tip. The _second glume_ is chartaceous, oblong-lanceolate, acuminate, usually 5-nerved (and occasionally 3-nerved), the mid-nerve keeled with a narrow wing from below the middle to the base and with hyaline margins. The _third glume_ is oblong-obovate, hyaline, thin, paleate with three yellow _anthers_ and two oblong-cuneate _lodicules_; _palea_ is narrow, oblong, obtuse. The _fourth glume_ is thin, hyaline, oblong-lanceolate, obtuse, paleate, and bisexual; _palea_ lanceolate, narrow, two-toothed at the apex, with deep purple _anthers_ and _stigmas_ of the same colour. The _lodicules_ are obliquely truncate. _Ovary_ has a reddish spot between the style branches and just at the apex in the fresh state in the bud and in the open flower.
