common woody climbing plant of the Brisbane Eiver bank ; the other 

 a tree very plentiful in Tropical Queensland and in plantations about 

 Brisbane. 



Tribe 10. Sophoeeje. — Trees, woody climbers, or rarely tall 

 shrubs or almost herbaceous. Leaves pinnate, with several leaflets, 

 without stipellse, or reduced to a large leaflet. Stamens all free or 

 scarcely united at the base. Examples : Sophora, Castanospermum, 

 the Moreton Bay Chestnut or Bean tree. A species of the first-named 

 genus is often to be met with on the borders of scrubs; another forms 

 a small tree on the tropical coast. 



Tribe 11. SwAETziEis. — Tall shrubs or trees. Leaves pinnate, with 

 many or reduced to 1 leaflet. Petals 6, 1, or none. Stamens indefinite 

 or rarely 10, free. Pod not articulate. So far as known, no repre- 

 sentative of this tribe is to be seen in Queensland. 



SnBOEDiJE II. c.a:sALPi]sriE^. 



Flowers usually 5-merous, very rarely 4-m6rous 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 campanulate 

 or tubular calyx with the stamens near the base, as in Papilionace83, , 

 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 some genera some or all of the 

 four lower petals wanting. Stamens 10 or fewer, or 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. From this suborder is obtained timber, 

 dyes, gums, medicines, and perfumes. 



Tribe 12. SctEROLOBiEiE. — Leaves impari, or rarely abruptly 

 pinnate. Calyx segments usually divided to the disk, imbricate. 

 Petals 5, slightly unequal. Ovary stipitate. Ovules 3 or many. No 

 representatives to be seen in Queensland. 



Tribe 13. Etjcjssalpinie^. — Leaves all bipinnate or rarely 

 bipinnate and simply pinnate on the same plant (see OleditscMa). 

 Calyx divided to the disk. Petals usually 5, subequal or but slightly 

 unequal. Stamens 10 (or fewer in Gleditschia) . Anthers versatile. 

 Ovarystipitate.- Ovules 2 or many, or rarely 1. For examples see 

 OcEsalpinia, Rwmatoxylon, and OleditscMa, Divi-divi, Logwood, and 

 Honey Locust, all common trees in cultivation. 



Tribe 14. CissiEiE. — Leaves impari or abruptly pinnate. Calyx 

 segments or sepals 5, rarely 4 or 3, free to the base, imbricate or very 

 rarely subvalvate. Petals 5 or fewer or more. Stamens 2 to 10 ; 

 anthers basi or dorsifixed, dehiscing by longitudinal clefts or pores.

 Ceratonia, Pudding-pipe tree, and the Carob. 



Tribe 15. Bauhinib^. — Leavej simple, entii-e, 2-lobed, or rarely 

 2-foliolate. Calyx above the disk gamosepalous or valvately parted, 

 the apex often 6-dentate, or rarily 5-lobed. Petals 5. Anthers 

 versatile. Ovary stipitate, free, or the stipes adnate to one side of 

 the ealyx-tube. Ovules 2 or many; seed albuminous. 'Examples:
