The examples of this species with spinulose nuts are easily distinguished from 
S. racemosa ; but some of the material is scarcely separable. 
42. S. griegifolia, C’. B. Clarke. Glabrous or nearly so. Stolons 
slender. Stem 12-16 in. long, with only 1 leaf-bearing node in the 
middle. Leaves (close to the base) several, 8-12 by 4-4 in., flat, 3-

glumes, uppermost ovate-lanceolate containing the pistil. Style very 
short; branches 3, long. Nut ;’; in. long, ovoid, round-trigonous,

In this species, as in the preceding, the 2 forming the genus Acriulus of Ridley, 
the style is rather short, the 3 branches long,
