[Vol. VIII, Art. 115 



side of the leaf base subauriculate and with 1 to 3 very- 

 short extra nerves, all similar in color and vestiture to the 

 comparatively bold midrib; petiole very short yet distinct; 

 stipule deciduous, I cm long, 3 cm wide at the base or a 

 little wider, setaceously pointed, pseudostrigose on both sides, 

 dull greenish in the dry state. Flowers in axillary clusters, 

 the 2 sexes upon different plants or at least upon different 

 stems of the same cluster; the staminate clusters larger, 

 whiter and less ciliately hairy than the pistillate clusters; 

 inflorescence in quadrangular clusters, subsessile, diverse in 

 size, the largest ones nearly 2 cm wide across the widest 

 portion, obscurely bilobed; involucre very thick and coria- 

 ceous, greenish, glabrous, the segments more or less united 

 into a disk-like receptacle whose margins curve upward and 

 enclose the flowers, slightly roughened on the exterior; flow- 

 ers grouped in 4's, surrounded by a 6 segmented involucel; 

 bracts averaging 3 mm long, hyaline except the midrib 

 and the apical margin which are greenish colored, about 2 

 mm wide, a trifle wider across the truncate apex, edges 

 finely ciliate; florets about 6 or only 4 in a group, surround- 

 ed by a whorl of 3 segments; bracteoles 2 to 3 mm long, 

 unequal in width, transparent except the greenish midrib 

 which is densely ciliate along the keel toward the obtuse 

 to acute apex; pedicels also transparent, ribbon -like 2 mm 

 long or longer, very short in the bud state; perianth seg- 

 ments 4, united toward the base, 1.5 mm long, ovately 

 elliptic, with acute slightly green colored apices; glabrous 

 filament also short in the young state, slenderly elongated 

 when mature; anther less than 1 mm long, basifixed, apical 

 portion bilobed, inflexed while in bud, sprung back in 

 anthesis. Perianth of the seeded heads greenish, densely 

 ciliate; seeds minute, bony, brown, elongated, very minutely 

 pitted.
