Hab. Sandwich Islands: Hawaii, on Mouna Loa, six miles from 

 the crater Lua Pele : Kauai, on mountains : Maui, on mountains in 

 the western division of the island. 



" Boot edible" according to Dr. Pickering's notes ; therefore probably 

 tuberous. Stems twining, slender, retrorsely and minutely hirsute- 

 pubescent, as are the petioles and peduncles ; and the leaves are beset 

 on both sides with a similar pubescence. Stipules and stipels subulate, 

 minute. Leaflets linear or linear-lanceolate, li to 2 inches long, and 

 from one to 4 lines wide, acutish or obtuse, mucronulate, of a rather 

 firm texture, and of the same hue both sides, rather conspicuously 

 reticulated with transverse veinlets, abrupt or retuse at the base, short- 

 petiolulate. Peduncles shorter than the leaf, an inch or less in length, 

 2-A-flowered. Pedicels opposite in pairs, 3 or 4 lines long. Flower 

 almost an inch in length. Calyx deeply four-toothed, subtended by a 

 small deciduous bractlet; the teeth nearly equal in length, fully as 

 long as the tube; the uppermost ovate, very obtuse, or slightly emar- 

 ginate; the others subidate. Corolla " yellow or yellowish :" vexillum 

 on a very short claw, obovate, entire, with two semilunar callosities 

 and two short and auriculate deflexed basal appendages: aloe nar- 

 rowly oblong, straightish, shorter than the carina, furnished with a 

 spur-like appendage at the base of the lamina. Carina straightish 

 or merely arcuate, as long as the vexillum, somewhat beaked ; its 

 petals partly united, similar, each with a minute inflexed auricle at 

 the base of the lamina. Stamens diadelphous : the free filament not 

 geniculate or appendaged at the base. Ovary hirsute, many-ovuled. 

 Style filiform, slightly incurved, much longer than the ovary, the 

 upper part not dilated, and only slightly flattened on the back, the
