It is probable that further field study may show that neither of the proposed 

 varieties is valid. The original specimens of Junod, 747, on which /. Iracht^- 

 adenia^ Pas & K. Hoffm. , is based, belong in some ca:>ed to var. platypkylla^ Pax, 

 and iVeZ^ori, 119, shows the same transition. At the same time, the distinction 

 between var. platyphylla, the type of which Pax has referred to /. Woodii as well 

 as to J, Zeyheri, is quite aibitrary, and the truth appears to be that, exactly as in 

 J. I> oodii and in J, natalensis, there is in J. Zeyheri every transition from a 

 lanceolate or ovate-lanceolate or ovate entire leaf to a lyrate- or mneinnte- 

 pinnatifid one.

Closely reBemhline J, ZeyJieri, Socd.,/. JSchlecJderi is easily distiDguished by its 

 uniformly petioled leaves with obtuse denticulate lobes and lobules., by its laxer 

 cymes with smaller flowers and by its glabrous petals. 



' XXI. CLUYTIA, Linn. 



Plowers dioecious, very rarely monoecious ; petals present in both 

 sexes ; disc of free lobulate glands at base of the sepals in both 

 sexes or very rarely in male flowers only. Male : Sepals 5, imbri- 

 cate. Petals usually almost as Jong as sepals, clawed, with one or 

 ^ore glands at the base within. Stamens 5 ; filaments connate 

 around and supporting a dilated rudimentary ovary ; anthers short, 

 dorsifixed; dehiscence longitudinal. Female: Sepals 5, imbricate. 

 Petals as in male. Ovary 3-celled ; ovules solitary in each cell;
