narrowed, the upper surface glabrous, the lower thickly and minutely 
pubescent, more hairy along the midrib, 13 cm long, 2 to 3 cm wide; 
petiole very short; ligule short, glabrous. Panicle lax, 11 cm long, with 
numerous, remote, slender, spreading, 1 cm long branches. Bracts cadu- 
cous, linear-oblong, obtuse, 3 mm long. Flowers white, nearly sessile, 
on short articulations. Bracteoles lanceolate, obtuse. Calyx infundi- 
buliform, with three, unequal, ovate lobes which are keeled and mucro- 
nate, glandular-dotted. Corolla-tube twice as long as the calyx, slender, 
the lobes reflexed, boat-shaped, the upper one hooded, mucronulate. 
Staminodes longer, linear, obtuse, thinner. Lip narrow, deeply bifid and 
with narrow blunt linear lobes. Anther-cells rather narrow, linear, the 
spurs lanceolate, acuminate, rather narrow, curved. Fruit white.

This species is distinguished by its quite glabrous sheaths and ligules, while 
the lower surface of the leaves is pubescent. It differs from G. gracilis K. Sebum., 
not only in its glabrous sheaths, but also in its linear obtuse staminodes.

A stout or slender plant 30 to 45 cm tall, the basal sheaths more or 
less hairy, always ciliate on the edge. Leaves lanceolate to ovate or 
elliptic-ovate, acuminate, 15 cm long, 6 cm wide, the base cuneate, the 
upper surface glabrous, the lower hairy ; petiole very short and hardly 
distinct; ligule very short, rounded, hairy, ciliate on the edge. Panicle 
dense, very shortly peduncled, 4 cm long, at first fusiform, later dilated 
and almost oblong, the racliis hairy. Bracts persistent, ovate, rounded, 
glandular-dotted, ciliate on the edge and often pubescent all over, the 
lowest ones 1 cm long and containing bulbils, frequently all the bracts 
bulbiferous and flowerless. Bulbils conic, acuminate, green, warty when 
dry, frequently produced also in the axils of the leaves. Flowers yellow, 
on short branches, unilateral. Floral bracts oblong, cuspidate, glandular- 
dotted. Ovary warted, glabrous. Calyx tubular, hardly dilated upward, 
3-toothed, two teeth mucronulate, one shorter, lanceolate, not mucronu- 
late, all glandular-dotted. Corolla-tube three times as long, glandular 
and subpubescent, the lobes ovate, minutely pubescent, glandular-dotted.
