224 NATURAL HISTORY OF PLANTS. 
twenty-two species are known.’ Their leaves are alternate impari- 
pinnate, with indefinite or few leaflets sometimes possessing setaceous 
stipels. The stipules are very small and narrow, or absent. The 
flowers form simple or ramified terminal racemes; each flower, axil- 
lary to a bract, is accompanied by two lateral bractlets, usually ill- 
developed, inserted at the base of the pedicel or at a variable height 
on it. 
S. japonica’ has been made by some authors the type of a genus 
apart,’ because of the pulpy or fleshy substance of its pericarp. The 
character may Le held to distinguish a section of the genus Sophora. 
S. secundiflora‘ has also been classed in a distinct genus’ because its 
pod is hard, woody and somewhat compressed. 
LEidwardsia’ has also been usually made a distinct 
genus, because the pod here often possesses four 
longitudinal wings, and the standard is mostly, 
though not constantly, erect and shorter than the 
keel. The most recent authors only admit these 
groups as sections of the genus Sophora. 
Next to Sophora come thirteen nearly allied 
genera, with a similar perianth and an ovary gene- 
rally containing more than three ovules, and some- 
times even a large number. They are as follows: 
Gourliea, Ammodendron, Ammothamnus, Virgilia, Cal- 
purnia, Cladrastis, Castanospermum, Alexa, Ormosia, 
Pericopsis, Bowdichia, Diplotropis, and Spirotropis. 
In Monopteryx the leaves are also pinnate, but the 
ovary is uniovulate, bringing the genus very near 
Dalbergiee. 
The five genera: Baphia, Leucomphalus, Dalhousiea, 
Bowringia, and Panurea, have unifoliolate leaves and indefinite 
ovules.
