69. LONCHOCARPUS, H. B. and K. 
(Pods lance-shaped.) 
Calyx truncate or very broadly and shortly toothed. Standard orbicular, 
obovate or rarely oblong ; wings usually slightly adhering to the keel ; keel nearly 
straight or incurved, obtuse. Upper stamen free at the base, connate with the 
others in the middle ; anthers uniform. Ovary with 2 or more ovules ; style 
incurved, stigma small, terminal. Pod very flat, oblong or broadly linear, thin or 
rather thick and coriaceous, indehiscent, the upper or both margins sometimes 
thickened or bordered by a prominent nerve, but not winged. Seeds usually 1 or 
2, rarely more, flat, reniform or orbicular. — Trees or woody climbers. Leaves 
pinnate ; leaflets usually few, opposite, with a terminal odd one ; stipellas none or 
small and setaceous. Stipules small or none. Racemes or raceme-like panicles 
axillary or forming large terminal panicles. Flowers violet, purple, or white, 
usually in pairs or in clusters along the rhachis. Bracts small, deciduous ; 
bracteoles also small, but often more persistent. 
A numerous genus in S. America and tropical Africa, but as yet unknown in Asia. The only 
Australian species is endemic, coming, however, very near to some African paniculate species, 
generically distinguished by Fenzl under the name of Philenoptera , and by Klotzsch under that 
of Capassa. In flower, Lonchocarpus cannot always be distinguished from Millettia , but the pod 
is always thinner and indehiscent, the pod alone distinguishing the genus from Derris and 
Pongamia. — Benth. 
1. I«. Blackii (after Allan Black), Benth. FI. Austr. ii. 271. A tall woody 
climber, the young branches and foliage rusty pubescent, at length glabrous. 
Leaflets 7 to 11, ovate, shortly and obtusely acuminate, 1 to 1£ or rarely above 
2iu. long, on rather long petiolules, with small setaceous stipellae. Flowers dark 
purplo, in long loose racemes, forming large terminal panicles, the pedicels 
usually 2 together on a short common peduncle. Calyx about 2 lines long, 
slightly silky-pubescent, with short broad teeth. Standard about 4 lines broad, 
narrowed into a long claw ; keel nearly as long, obliquely ovate ; wings very 
small. Ovary very villous, with numerous ovules ; style short, inflexed. Pod 
very thin, 2 to 5in. long, ^ to fin. broad, with 2 to 4 or 5 broad flat reniform 
seeds. — Millettin Blackii, F. v. M. Fragm. ii. 123. 
Hab.: Brisbane River, Moreton Bay, F. v. Mueller , W. Hill, Leichhardt; Ipswich, Nernst ; 
Broadsound and Bowen River, Bowman ; Rockhampton, Dallachy. Flowers about November. 
Wood very stringy, dark-brown, and porous. — Bailey's Cat. Ql. Woods No. 119. 
Yields a blood-red juice, which, on exposure to air, dries up to a brownish gum. Analysis : 
Arabin, 3'8 ; resin, 1-4; tannic acid, 74-2 ; water, 20 6. — Lauterer. 
70. DERRIS, Lour. 
(Pods thin, skin-like.) 
(Brachypterum, W. and Am.) 
Calyx truncate or very shortly and broadly toothed. Standard obovate or 
orbicular ; keel slightly incurved. Upper stamen usually free at the base, united 
with the others in the middle ; anthers uniform. Ovary sessile or shortly 
stipitate, with several ovules ; style incurved, with a small terminal stigma. Pod 
flat, oblong or linear, straight or slightly incurved, thin or coriaceous, indehiscent, 
the upper or both sutures bordered by a narrow wing. Seeds 1, 2 or rarely 3, 
very flat, orbicular or reniform. — Tall woody climbers or rarely trees. Leaves 
pinnate ; leaflets opposite, with a terminal odd one ; stipellas small and setaceous 
or none. Stipules small or none. Flowers white, yellowish or rarely violet, 
usually clustered on lateral nodes along the rhachis of axillary racemes. Bracts 
and bracteoles small and deciduous.
