in which the seeds are isolated by transverse septa. Coronilla (Fig. 649). 

 Oriiithopus sativus, Bird's-Foot. Arachis hypoijaea, Ground-nut, an important, 

 oil-yielding fruit of the tropics and sub-tropics. After flowering the flower-stalks 

 penetrate the soil in which the fruts ripen. — 8. Vicieae. Leaves with terminal 

 tendrils, corresponding to the terminal leaflet ; the leaves may thus appear to be 

 paripinnate. The cotyledons remain within the seed-coat and do not become green. 

 Stamens (9) + l. Vicia, Vetch; Pisum, Pea; Ervum, Lentil; ia<%rMS, Everlast- 

 ing Pea. Vicia Faba, the Broad - 

 Bean, is an erect plant, without 

 tendrils ; the terminal leaflet is 

 reduced to a bristle - shaped 

 stump. 9. Phaseolcac. Twining 

 plants with tripinnate leaves. 

 Cotyledons usually come above 

 ground and turn green. Stamens 

 (9) + 1. Phascolus, Kidney 

 Beau. Physostigma. 



Poisonous. — Among our 

 common Leguminosae only 

 Cytisus Laburnum is extremely 

 poisonous. The other species 

 of the genus, e.g. C. al]}inus, 

 C. purpureus, C. Weldeni, and 

 C. hiflorus are poisonous, but 

 are more rarely met with than 

 the ordinary Laburnum. Cor- 

 onilla varia (Fig. 649), with 

 umbels of rose-coloured flowers, 

 and Wistaria sinensis are also 

 poisonous. 



Official. — Astragalus 

 gummifer and other species 

 yield tragacantha. Glycyk- 

 RHIZAE RADIX is obtained from 

 Glycyrrhiza glabra. Spartium 

 scopariitm yields scoparii ca- 

 CUMINA. Physostigma venosum, 

 a West African climber, yields physostigmatis semina. Calabar Bean. Anclira 

 araroba, a Brazilian tree, contains a powdery excretion in cavities of the stem 

 called araroba; chrysarobinum is obtained from this. The heart- wood of 

 Ptcrocarpxis santalinus, an East Indian tree, is pterocarpi lignum. Kino is 

 obtained from the juice flowing from incisions in the trunk of Pterocarptis 

 iiiarsupium. Myroxylon toluifera (S. America) yields balsamum tolutanum, 

 and M. Pereirac (San Salvador) balsamum peruvianum. 



Fig. 649. — Coronilla varia (nat. size). Poisoyous.
