75. BARKLYA, F. v. M. 
(After H. Barkly, a Governor of Victoria.) 
Calyx-teeth very short and obtuse. Petals all free, obovate, erect, similar and 
nearly equal, on long claws, the upper outer one or standard rather broader than 
the others. Stamens 10, all free, longer than the petals ; anthers sagittate. 
Ovary stipitate, with several ovules, tapering into a short style with a minute 
terminal stigma. Pod stipitate, flat, the valves thin and scarcely separating. 
Seeds flat, albuminous ; cotyledons obovate, flat ; radicle indexed. —Tree. Leaves 
simple (unifoliolate), petiolate. Flowers small, yellow, in dense racemes. Bracts 
very small ; bracteoles none. 
The genus is limited to a single species, endemic in Australia, approaching in habit and in the 
small regular flowers to some Ccesalpiniece allied to Bauhiuia , but with the floral aestivation and 
the embryo of Papilionacecc. — Benth. 
1. B. syringifolia (Lilac-leaved), F. v. M. in Journ. Linn. Soc. iii. 158, and 
Fragm. i, 109, t. 3 ; Benth. FI. Aastr. ii. 275. A handsome tree, attaining from 
20 to 60ft., glabrous, or the young shoots and inflorescence rusty-tomentose. 
Leaves very broadly cordate, ( shortly acuminate, 2, 3, or even 4in. long, and often 
as broad as long, entire, 5 to 7-nerved, on a petiole of 1 to 2in., slightly 
thickened at the base and at the top. Stipules small, ovate, deciduous. Flowers 
of a bright golden yellow, in dense racemes of 6 to 9in., forming handsome 
terminal panicles. Pedicels short. Calyx about 2 lines long. Petal-claws rather 
longer than the calyx, the lamina about as long. Ovary glabrous, with 3 or 4 
ovules. Pod oblong-lanceolate, oblique or slightly falcate, 1J to 2in. long and 
about Jin. broad, narrowed at the base, with 1 or 2 seeds. 
Hab.: Near Brisbane, W. Hill, Fitzalan ; ltockhampton, Dallachy ; Wide Bay, Leichhardt. 
Var. tortuosa. Is a stunted form with zigzag branches, reminding of Robinia Pseudo-acacia 
var. tortuosa. It was raised from seed by Mr. A. J. Hockings. 
Wood blackish-grey, close in grain, very tough ; suitable for tool-handles. — Bailey's Cat. Ql. 
Woods No. 123. 
Suborder II. C^SALPINIEflE. 
Flowers usually 5-merous, very rarely 4-merous or 3-merous, the sepals united 
at the base into a short tube, lined by the disk, bearing at its margin the petals 
and stamens, rarely forming a eampanulate or tubular calyx with the stamens 
near the base, as in Papilionacece, the free part of the sepals or lobes of the calyx 
imbricate or rarely valvate. Corolla irregular or nearly regular, either with the 
5 (or 4 or 3) petals variously imbricate in the bud, but the upper one never 
outside and usually quite inside, or in genera not Australian, some or all of the 
four lower petals wanting. Stamens 10 or fewer, or in genera not Australian, 
indefinite, free or rarely more or less united, all perfect or several of them reduced 
to staminodia. Ovules anatropous or nearly so. Radicle of the embryo short 
and straight. 
The tropical genera of this suborder are numerous, and have been distributed into several 
tribes, but these are not sufficiently marked to render it necessary to apply them to the few 
genera found in Australia. Barklya amongst Sophorece has the regular corolla of some 
Ccesalpiniece, but with the aestivation of Papilionacecc, and Erythrophlceum amongst Uimosecc has 
the imbricate aestivation of Ccesalpiniece, but in a very slight degree, with the inflorescence 
haracteristic of Mimosece. — Benth. 
76. CzESALPINIA, Linn. 
(After Dr. Caesalpinus.) 
Sepals 5, shortly united at the base, much imbricated, the lowest one larger 
and concave. Petals 5, spreading, rather unequal, the upper inner one the 
smallest, the two lowest outer ones the largest. Stamens 10, free ; anthers 
uniform, ovate. Ovary with 2 or more ovules ; style subulate, with a small
