Jdenanlhera,'] XL. LEGUMlNOSiE. - 299 



Fragrueuts of a plant evidently belonging to this genus, but insufficient for determination, 

 are lo F. Mueller's collection from Gilbert river. One imperfect leaf is like tliat of J, pavo- 

 mna, but with it are two loose pods which I can only compare with those of a Borneo plaut 

 m the Kew herbaria. They are short, slightly falcate, and the seeds more like those of the 

 Cingalese A. bicolor, which, however, has very different leaves.

Calyx 5-toothed. Petals 5, valvate, usually cohering. Stamens in the 

 perfect flowers 10, free; anthers ovate, tipped with a deciduous gland. 

 Ovary nearly sessile, with several ovules ; style short or filiform, with a small 

 terminal stigma. Lower flowers of the spike neuter, with long, linear, 

 ^'hite or coloured stamiiiodia, and a small rudimentary ovary. Pod linear, 

 compressed, variously twisted, indehiscent or the valves iiTegularly separating 

 trom the persistent sutures. — Rigid shrubs, the branchlets occasionally spines- 

 cent Leaves abruptly bipinnate, with a stipitate gland between the pinnae 

 of the lowest or of all the pairs ; leaflets small Stipules subulate or acumi- 

 ^ate,^ften imbricate on the short flowering branches. Flowers sessile, in 

 aease cylindrical spikes, either terminal or apparently axillaiy by the short- 

 ness of the braiichlet, the upper flowers of the spike hermaphrodite and 

 yellow, the lower ones neuter and white pink or purple. 



^he genus extends over tropical Africa and Asia. Of the Australian species one is the 

 bTrh°"r ^^^" one, the other is endemic. F. :Mucller proposes to reunite it with Neptunia, 

 , 1 ^'^^^^'^ee in the pod is accompanied by too marked a difference in habit to be neg- 

 ected unless the whole of the Mimosea with definite stamens and gland-tipped anthers be 

 "nited into one genus.
