A prostrate undershrub from a much thickened woody root, 
the branches spreading, prostrate, distinctly woody, slender, 
up to 40 cm in length, branched, the branches and branchlets 
dark reddish-brown, glabrous,- terete, or the ultimate ones very 
obscurely angular. Leaves 1.5 to 3 cm long, 1- to 4-jugate, the 
pinnae 1 cm long or less ; leaflets 12 to 16 pairs, sessile, oblong, 
thick, 2 to 3 mm long, obscurely nerved, base inequilaterally 
rounded, apex obtuse to minutely apiculate, margins in young 
leaves sparingly ciliate; stipules inequilateral, slenderly acumi- 
nate, ovate, about 3 mm long. Heads axillary, yellow, their 
peduncles slender, 2 to 3 cm long. Lower flowers neuter. Calyx 
less than 1 mm long. Petals somewhat oblong-oblanceolate, 2 mm 
long, free. Staminodes petaloid, yellow, flat, membranaceous, 
linear-oblanceolate, about 1 cm long. Perfect flowers : Calyx 1.5 
to 2 mm long, the teeth 5, ovate, obtuse to subacute, 0.5 mm long. 
Petals 5, free, about 2.5 mm long, oblong-spatulate. Filaments 
filiform, 4 mm long; anthers oblong-elliptic, 1 mm long, falling 
very soon after anthesis, tipped with a minute sessile gland. 
Ovary subsessile, compressed, oblong, inequilateral, glabrous; 
ovules about 6; style 3 mm long. Pods oblong, thin, brown, 
about 2 cm long and 5 mm wide, minutely apiculate.

This species in many respects resembles Neptunia triquetra Benth., 
which extends from India to Indo-China, but is smaller, with much smaller 
leaves, and with but five stamens, and very different staminodes. It is 
distinctly woody, the root being much thickened, the prostrate stems not 
at all herbaceous. On account of its five stamens its true alliance is with 
the Australian Neptunia gracilis Benth. and N. monosperma P. Muell., 
being more distinctly allied to the former. It is easily distinguished from 
Neptunia gracilis Benth. by its much smaller leaflets.
