Branchlets beset with minute hairlets, not angular ; leaves on 

 very short petioles; [)innules in 6 or 5 or rarely less pairs, rather 

 distant, almost sessile, rachis minutely puberulous, bearing a very 

 small de[)ressed glandule between each racheole ; leaflets in 16 or

 concave, with an acute somewhat recurved apex, on both sides of 

 the same deep green ; flower-headlets simply racemous, their 

 peduncles of somewhat less length during anthesis and like the 

 rachis and flowers nearly or quite glabrous ; bracts very much 

 shorter than the flowers ; calyx about as broad as long, sinuate-

 curved, glabrous ; seeds placed almost diagonally, occupying most 

 of the breadth of the valves, broadly ovate, rather turgid, deep 

 black, somewhat shining, their lateral areoles large, but of faint 

 demarcation ; funicle very short and almost straight ; strophiole 

 whitish, dimidiate-ovate and somewhat cymbiform, of one-third or 

 hardly half the length of the seed.
