 CarpoUthes spiralis, Lesqx., SupjiltMiieiit to Annual Report, 1871, p. IC. 



A large, apparently hard fruit, four and a half centimeters long, nearly 

 liiree centimeters broad ill the upper part, ohovale, rounded, gradually nar- 

 rowed downward to its lower end, where it is broken and still seventeen 

 millimeters broad, deeply furrowed in spiral lines passing downward from 

 the upper border, and strangled horizontally above its base by two strong 

 lines cutting the spiral ribs without changing their direction. Tiiis fruit has 

 some likeness of form, especially by its spiral or oblique costse, to the nut of 

 Torre y a Californica.

Pods(?) square or rhomboidal in outline, flattened at the borders, inflated 

 in the middle, twelve millimeters in diameter. They look like a one-seeded 

 legumen. Fig. 28 seems to bear inside, and in a mature state, a seed which 

 is nearly exactly ovate-acute. Fig. 23 appears empty or immature.
