Order LEGTJMIlffOS^. 



Amongst Dicotyledons this order stands second in point of 

 numbers. It contains about 7,000 species in 4*00 genera, and the 

 species are met with in every part of the globe. 



Plowers, irregular, usually hermaphrodite; regular, usually 

 polygamous. Known species over 6,-500. Next to Composite, this is 

 the largest natural order of phsenogamous plants, Calyx of 5 or 

 rarely fewer usually united sepals, campanulate or tubular, more or 

 less divided into 5 or fewer teeth or lobes, or rarely the sepals 

 entirely distinct. Corolla of 5 or rarely fewer petals, perigynous or 

 rarely hypogynous ; very irregular in the first suborder (PapiIionac?e), 

 less so in the second (CsesaipiaiesB), small, regular, and the petals 

 often united in the third (Mimosese). Stamens twice the number of 

 petals, rarely fewer, or sometimes indefinite, inserted with the petals. 

 Ovary single (consisting of a single carpel), with 1, 2, or more oyules 

 arranged along the inner or upper angle of the cavity ; style simple. 

 Fruit, a pod (legume) , usually flattish, and opening round the margin 

 in 2 valves, but sometimes follicular or indehiscent, or variously 

 shaped. Seeds with 2 large cotyledons, a short radicle, and, with few 

 exceptions, little or no albumen. The species consist of herbs, shrubs, 

 trees, or climbers. Leaves alternate, or rarely opposite, usually fur- 

 nished with stipules, compound, or reduced to a single leaflet, or to a 

 dilated petiole (phyllodium), or in a few cases really simple, the 

 leaflets or leaves entire or' rarely toothed or lobed. Elowers in 

 axillary or terminal racemes, spikes, or clusters, when terminal, often 

 becoming leaf -opposed by the growth of a lateral shoot rarely solitary 

 and axillary, 



SXTBOBDEB I. PAPILIONACB^. 



Flowers 5-merous. Corolla very irregular, papilionaceous, or 

 very rarely nearly regular, the petals 5, imbricate, the upper one, or' 

 standard, always outside in the bud. Stamens 10, or, very rarely, 

 9 or 5. This suborder supplies many important fodders, culinary 

 vegetables, dyes, fibres and medicines. 



Tribe 1. PoDALTEiEiE.-^Shrubs, rarely herbs and very iiarely 

 climbers or small trees. Leaves simple or digitately compound, very 

 rarely pinnate. Stamens 10, all free or scarcely united at the base. 

 Pod not articulate. Examples'; Daviesia, PultentBa, or the common 

 Dogwood, Jaeksonia scoparia. Species of the two first as well as the 

 last named plants are amongst the most common of our Queensland 

 shrubs. 



Tribe 2. Q-EiriBTEai. — Shrubs or herbs, very v^x^j small trees. 

 Leaves simple or with 1 or 3 or more digitate leaflets, rarely %• 

 foHolate. Stamens all united in a sheath open on the upper sifte in 

 all the Australian genera (except in a species oi ffovea). Example:
