186 MANN, 



slender herbaceous branches, glabrous throughout. Stipules ovate, 

 obtuse, persistent. Leaflets ovate, from roundish to oblong-ovate, 

 more or less acuminate, 2k' -5' long, membranaceous, triplinerved. 

 Petiolules 3" -4" long, exceeding the stipellae. Racemes axillary, at 

 least twice the length of the leaves, 8'- 18' long, the rachis with many 

 nodes, each node with about 3 flowers, or sometimes the flowers on 

 the apex of a short peduncle. Bracts very caducous. Pedicels 1' or 

 more long, equalling the developed flower in length, with a pair of 

 caducous ovate bractlets immediately under the calyx. Calyx cam- 

 panulate, 3" long, 5-toothed, teeth very broad and obtuse ; the two 

 upper ones very nearly united in one. Corolla bright red. The 

 standard thrice the length of the wings, its base appendiculate on 

 each side by a strongly inflexed membrane ; the face callose as if by 

 an adherent membrane, which is denticulate at the upper edge, and 

 produced on each side into a free and salient auricle or lamella. 

 Ovary on a stipe at length longer than itself and as long as the calyx, 

 glabrous, compressed, 1- or more frequently 2-ovuled. Style very 

 long and capillary. Stigma terminal, and with minute hairs. Pod 3' 

 long, 1^' wide, on a stipe li' or more long. 



Kaala Mountains, and mountains behind Honolulu, Oahu. Forests on the slopes of 

 Mouna Loa, Hawaii. Also Vitl Islands. 



9. MTJCUNA Adanson. 



Two upper calyx-teeth wholly connate. Standard shorter than the 

 other petals, appendaged with inflexed auricles at the base. Keel as 

 long or longer than the wings, curved and usually tipped with a carti- 

 laginous beak. Stamens diadelphous. Ovary villous, few-ovuled; 

 style filiform, with a small terminal beak. Pod thick, ovate-oblong or 

 elongated, usually covered with stinging hairs, 2-valved. Seeds with 

 an oblong or linear hilum. Twiners or tall climbers. Leaflets 3, the 

 stipellse subulate or sometimes wanting. Eacemes on long axillary 

 peduncles. Flowers large, pedicellate, arising from nodes of the 

 rachis, often showy. Bracts small or caducous.

1. M. GIGANTEA DC. (Enum. No. 107.) A tall climber. Leaf- 

 lets ovate, rounded at the base, obtuse at the apex, 2' - 4' long, the 

 two lateral ones often unequal, glabrous. Racemes near the end of a 

 peduncle, 4' - 6' long, the pedicels approximate, 6" - 8" long, puberu- 

 lent. Calyx 4" long, quite truncate, or with very short teeth, puberu- 

 lent. Wings and keel 1' long, nearly twice the length of the standard, 

 glabrous or nearly so, sometimes with a line of hairs along the edge 

 of some of the petals. Ovary few-ovuled, sericeous, stipitate. Pod
