NATURAL HISTORY OF PLANTS. 



Toluifera Balsamum. 



twenty-two species are known. 1 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, usualty ill- 

 developed, inserted at the base of the pedicel or at a variable height 

 on it. 



8. japonica 2 has been made by some authors the type of a genus 

 apart, 3 because of the pulpy or fleshy substance of its pericarp. The 

 character may be held to distinguish a section of the genus Sopliora. 

 8. secundiflora 4 has also been classed in a distinct genus 6 because its 



pod is hard, woody and somewhat compressed. 

 Edwardsia 6 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, Virgi/ia, Cal- 

 purnia, Cladrastis, Castanospermum, Ahwa, Ormosia, 

 Pericopsis, Bowdichia, Diplotropis y and Spirofropis. 



In Monopteryx the leaves are also pinnate, but the 

 ovary is uniovulate, bringing the genus very near 

 Dalbergiece. 

 The five genera: Baphia, Leucomphalus, Dal/iousiea, 

 Boioringia, and Panurea, have unifoliolate leaves and indefinite 

 ovules.
