4- Z.prismB.tothec\imyF.MuelLinLirn^cea,xxy.Slo. A much-branched, 

 small annual. Leaves rather thick, the leaflets, in the few specimens seen, 

 short and confluent with the more or less dilated petiole, so as to form a 

 single 2-lobed leaf. Flowers, which I have not seen, small and 4-merous, ac- 

 cording to F. Mueller, the filaments dilated at the base and toothed or 

 entire. Capsules nearly sessile, oblong, 4-angular, about 4 lines long, of 



base 



erect leafy appendages. Seeds solitary in each cell.

 all the foliage of the 2-lobed varieties of Z. iodocarpum, Z. BiUanlieri and Z.fruticnlosum, 

 l>^t as in those species there is probably also a variety with normally 2-folioIate leaves,
