FLORA OF THE HAWAIIAN ISLANDS. 185 



elongated, erect or patent, nearly sessile or long clawed. Wings 

 short, sometimes none. Keel much shorter than the standard, joined 

 on the back or free. Stamens diadelphous, the alternate ones often 

 without anthers. Ovary stipitate, many-ovuled. Legume stipitate, 

 falcate, narrowed at the base and apex, more or less constricted be- 

 tween the seeds, 2-valved. — Shrubs or trees. Stipules small. Leaves 

 pinnately o-foliolate. Kacemes axillary and leafless, or terminal and 

 leafy at the base. Plowers showy, often red. Bracts small. 



A small genus, dispersed througli hot and tropical regions. 



1. E. MONOSPERMA Gciud. {Enuin. No. 105.) Tree with a broad 

 spreading top, about 30^ high, aculeate on the young branches with 

 short prickles. Petioles, peduncles, «&c., tomentose. Leaves 6' -8' 

 long; leaflets broadly triangular-ovate, truncate at the base, obtuse, 

 2h'-5' long and about as broad, terminal one much larger than the 

 lateral ones, glabrous above, pubescent beneath. Eachis very stout 

 and woody, 6' long, many- (15-25-) flowered. Flowers red, much the 

 color of red coral, with some yellow, showy. Calyx 3" -4" long, 

 truncate, or slightly toothed, very tomentose-pubescent. Standard 

 more than an inch long and nearly as broad as long, 3 times longer 

 than the obtuse wings and keel. Stamens nearly as long as the stand- 

 ard, 9 of them united to the middle, the tenth free. Ovary ^' long, 

 half the length of the style, very tomentose. Pod l^'-4' long, 1 to 

 several-seeded (the name monosperma hence badly adapted to the 

 species). Seeds about h. inch long, bright red. 



Dry slopes of West Maui. Kawaihae, Hawaii, and similar places throughout the 

 group. Apparently much less common than formerly. 



8. STRONGYLODON Vogel. 



Calyx teeth broad, obtuse, nearly equal. Standard ovate-oblong, 

 acute, recurved or often reflexed, appendiculate, and with two callosi- 

 ties near the base. Wings much shorter than the standard, adhering to 

 the keel, which is long-beaked and incurved, equalling the standard in 

 length, and its two petals cohering on the back. Stamens diadelphous. 

 Anthers uniform. Ovary stipitate, 1 - few-ovuled ; style filiform, not 

 bearded. Pod stipitate, obliquely ovate-oblong, 2-valved, the valves 

 convex^and coriaceous. Seed large, orbicular. — Climbing vines, 

 woody at the base, and glabrous. Leaves pinnately 3-foliolate. Stip- 

 ules small. Flowers red, showy, fasciculately-racemed on long axil- 

 lary peduncles. Bracts quite small. 



Genus of 3 species, one in Luzon, one in New Hebrides, and the other in the Viti and 

 Hawaiian Inlands.
