***OPHRYOSCLERIA.—Moneecious spikelets none. Lobes of the dise forming a cup 
holding the base of the nut; margin of disc ciliate. Stout plants. Leaves (and 
lower bracts) unequally premorse on the sides near the top. 
Nut smooth, 
Nut large ; margin of disc densely ciliate . . 39. S. racemosa, 
Nut medium-sized; margin of disc slightly ciliate , 40, S. Vogelii. 
Nut verrucose, often tubercled . ; . 41. S. verrucosa, 
****ACRIULUS.—Female spikelets with no male rndiments, so that the female 
flower appears terminal. Hypogynous disc merely the stalk of the nut. Rather 
stout plants, with copious panicles . c i - 42. 8S. griegifolia. 
1. S. pergracilis, Kunth, Enum. ii. 354. Glabrous, or nearly so, 
annual. Stems tufted, 1-2 ft. long, very slender. Leaves 4-12 by 
zo-zz in. Spikelets (many 2-sexual) in clusters of 2—5, 1-1 in. long, 
sessile on a subsimple spike 2 to 6 in. long ; bracts to the clusters ovate, 
acute, and rarely longer than the clusters. Moneecious spikelet of 
about 7 glumes; the 2 lowest empty, the third {-} in. long, elliptic- 
oblong, not acute, dark-brown, carrying the nut; the upper glumes 
male or empty. There also occur many male spikelets, similar to the 
moneecious, except that they are without the 3rd. nut-bearing glume. 
Stamens 1-3; antherscrested. Nut ,j, in. in diam., obovoid, trigonous, 
white, verrucose or muricate. Style linear, not dilated at the base.

panicled. Spikelets nearly 4 in. long, chestnut-brown, 3-8 on one 
branch of the inflorescence. Nut zo in. leng, obovoid, trigonous,
