flowers or fruit. (Discovered by Menzies. on Mouna Loa, at the 

 upper edge of the forest : also gathered by Macrae, on Mouna Kea ; 

 in flower.) 



A nearly glabrous species, of most remarkable size. Stems elon- 

 gated, " climbing, tangled among shrubs," angled, minutely pubescent 

 or glabrous, very leafy. Stipules foliaceous, pectinately dentate with 

 long and subulate teeth, especially the lower ones, which are rounded or 

 flabellate and half an inch or more in diameter ; the upper half-sagit- 

 tate and acuminate. Leaflets 8 to 12, often 2 inches in length, ovate- 

 oblong, obtuse, membranaceous, veiny, mucronulate, commonly alter- 

 nate; the lowest near the stem. Tendrils compound. Peduncles 

 shorter than the leaves, 2 or 3 inches long, Q-9-floivered ; the pedicels 

 slender, approximate, 3 to 5 lines long. Flowers very large, from an 

 inch to an inch and a half in length, pale purple. Calyx-teeth as long 

 as the tube, 3 lines long, narrow, very acutely subulate, the lower one 

 a little longer than the others. Vexillum recurved, ecallose. Style 

 filiform, minutely pubescent all round above the middle. Stigma 

 terminal, minute. Legume unknown. 



This is much the largest-flowered species of the genus known; 

 and the leaflets are proportionally ample. The character and descrip- 

 tion, as to the flowers, are entirely drawn from a specimen gathered 

 by the late Mr. Macrae. The species is omitted in DeCandolle's 

 Prodromus.

This name has the priority in publication, I believe, over the 

 homonvmous L. sessilifolius of Tenore.
