Calyx campanulatus, subbilabiatus, 5-fidus. Vexillum alas oblongas superans. Carina alis adherens. 
Stamina basi monadelpba, filamento vexiilari ssepe ultra medium soluto. Ovarium sessile, pluri-ovulatum. 
Legumen lineare, compressum, intus septis cellulosis submultiloculare. — Herbse v. suffrutices, decumbentes

A genus of A • ge tropical genus), of which about eight species are 
known, chiefly natives of the east coast, one only being South-west Australian; it is also allied to Kennedy a, but 
differs much from that genus in habit, and in the large vexillum. — Decumbent or twining half-shrubby or herba- 
ceous plants, wi ifoliolate leaves, and elongated axillary peduncles, bearing long racemes or 
heads of flowers. Calyx campanulate, five-lobed. Standard broad, larger than the alae and carina. Stamens ten, 
diadelphous, or with the upper more or less united to the others. Pod linear, compressed, divided into many cells 
by broad spongy cellular septa. Seeds compressed, rounded, with a small strophulus. (Named from Actttos, slender, 
and Kva/xos, a bean ; in allusion to the slender pods.) 
1. Leptocyamus Tasmanicus (Benth. MSS.); herbaceus, pubeseenti-pilosus, pilis caulibus petiolis 
pedunculisque reflexis, caule brevi, ramis breviusculis basi decumbentibus ascendentibus, stipulis ovatis 
obtusis, foliolis obovato-oblongis v. cuneatis obcordatisve subtus sericeo-pubescentibus, pedunculis elongatis, 
racemis 3-8-floris, calycis lobis brevibus latis obtusis, legumine pubescente. (Gunn, 242.) (Tab. XVII.)

A small species, everywhere pubescent with short stiff hairs, which are reflexed on the stems, branches, 
petioles, and pedicels.— Stew short, stout, woody ; tranches short, 3-6 inches long, ascending. Stipules ovate, 
striate, blunt. Petioles f-2 inches long. Leaflets three, sessile, obovate, obcordate, or oblong-obovate, covered 
below with appressed hairs. Peduncles 3-8 inches long, three- to eight-flowered at the apex, tomentose towards 
the tip. Bracts small, broadly ovate. Pedicels very short. Flowers \~\ inch long. Calyx villous with appressed 
hairs, lobes short, blunt, with two very minute bracteoles at its base. Pod linear, f-1 inch long, curved, flat, very 
pubescent or almost hispid, three- to six-seeded. Seeds orbicular, compressed. 
I have seen but one South-east Australian specimen of this plant, gathered by Mr. Gunn at Port Philip. 
It is very nearly allied to Leptocyamus Latrobeanus (ZycMa, Muller), of the same country, which differs in the upper 
stamen being united with the rest, in the longer claw of the vexillum, and in the longer calycine lobes.— Plate
