40 PAPILIONACEOUS FLOWERS. [part i. 



Thus, the Chorozema is one of the kinds with 

 'thin cotyledons, and consequently its seeds are 

 not eatable. The legumes of this genus are 

 roundish, and swelled out, so as to bear but 

 little outward resemblance to a pod. Sophora, 

 Edwardsia, Virgilia, Podolobium, Callistachys, 

 Brachysema, Burtonia, Dillwynia, Eutaxia, 

 Pultensea, Daviesia, and Mirbelia, have all thin 

 cotyledons, and their ten stamens all separate 

 from each other ; but in Hovea, Platylobium, 

 and Bossisea, though the cotyledons are thin, 

 the stamens all grow together at the base. I 

 mention these common greenhouse shrubs, that 

 my readers may have an opportunity of ex- 

 amining their botanical construction, and thus 

 verifying their names. The common furze ( Ulex 

 europceiis)^ the Spanish broom {Spartium jun- 

 ceiim), the Petty whin {Genista Anglica)^ the 

 Laburnum ( Cy^?sw5 Lahurnum)^ and the common 

 broom, all belong to this division, and con- 

 sequently their seeds are not eatable ; those 

 of the Laburnum are indeed poisonous. The 

 distinctions between Spaitium, Genista, and 

 Cytisus, are very slight, lying chiefly in the 

 calyx; and as a proof of this the common 

 broom, which is now called Cytisus scoparius, 

 was formerly supposed to be a Spartium, and 

 afterwards a Genista.
