SupoRDEU III. MIMOSEiE. 



"Flowers B-merous, 4-nierous, or rarely 3-merous or 6-merous, small, re- 

 gular, sessile in spikes or heads or very rarely shortly pedicellate, often poly- 

 gamous. Sepals valvate, often united. Petals valvate, except in Eryihro- 

 pMceum, often united. Stamens equal to or double the number of petals or 

 indefinite. Seeds usually flattened, with a hard shining testa. Albumen 

 none or very scanty. Radicle of the embryo short and straight. Leaves bi- 

 pinnate, except in the American genus In(/a, 



The genera of this well-marked suborder are not uumerous in proportion to the species, 

 and are technically distributed into fonr tribes : — Parkiea:, with definite stamens and slightly 

 imbricate petals, 'including Erijikropkli£um ; EamhaoseiS, with definite stamens, including 

 Macla, Adenanthera^ Bickrosiachys, and Neptunia ; AcacietB, with indefinite free stamens, 

 consisting chiefly of the vast genus Jcacia ; and Int^ece, with indefinite mouadelphous sta- 

 mens, including Albizzia and Pithecolohium. 



S5. ERYTHEOPHLCETJM, Afzel. 



(Fillrea, Guillem. and Perr. ; Laboucheria, F. Muell.) 



Calyx-teetli 5, valvate in tlie bud. Petals 5, small, very slightly imijricate. 

 Stamens 10, inserted with the petals on a perigynous disk, free, longer than 

 tbe petals, all eqnal and perfect ; anthers ovate, withont glands. Ovary sti- 

 Pitate, with several ovules ; style short, with a terminal stigma. Pod oblong, 

 huear, flat, coriaceous, 2-valved. Seeds ovate, compressed, transverse; 

 fuuicle filiform ; testa pulpy outside ; albumen thin ; radicle short, straight. 

 Trees. Leaves bipinnate. Flowers small, almost sessile in long cylmdrical 

 spikes, forming a terminal panicle. Bracts inconspicuous. 



A small genus, coutaining, besides the Australian species, whldli is endemic, two or three 

 from tropical Africa. In the slight itnbnc-aliou of the petals it approaches Camlpunea, and 

 especially ifora, and maybe considered, with ParHa, as intermediate between that suborder 

 and true Mimosea. 



1- E. Laboucherii, F. Muell. Herb. A hard-wooded tree, the branches 

 anJ foliage glabrous. Pinnae opposite, in 3 or 3 pairs ; leaflets 4 to 9,^ al- 

 ternate, obliquely obovate or orbicular, very obtuse or retuse, mostly 1^ to 

 2 in. long. Spikes rather dense, nearly sessile, 1 to 3 in. long, blowers i 

 jo H lines long. Calyx spl-inkl6d and ciliate with a few hairs. Pe 



tals rather 



^oi>Ser than the calyx, with woolly edges. Stamens more than twice as long 

 «ltlie petals, distinctly inserted in 2 rows. Ovary shortly stipitate hairy, 

 ;;\th about 10 ovtiles. Pod 4 to 6 in. long, 1 to H in. broad flat with 

 «niily-coriaceons valves. Seeds nearly mh\^vil^x.-Labouchena chlorodachys,
