Distrib. Endemic. 



A third new species of the genus, not far removed from the last described, 

 and like it an ally of T. africanum, R. Br. (Prod. 496). But it is a much smoother 

 plant, and is further distinguished by its long lax inflorescences, small flowers with 

 a calyx not enlarging around the fruit, the nucules of which have a very broad 

 margin, folded in, bladder-like, over the back, which is irregularly tubercled. 



5. CYSTISTEMON. 

 Cystistemon, Balf. fil. in Proc. Roy. Soc. Edin. xii. (1882), 82. 



Calyx 5-partitus, segmentis linearibus, fructifer auctus nuculas includens. Corolla campanulafca, 

 supra staminum insertionem dilatata, fauce nuda ampliata ; lobi 5, ovati, acuminati, 

 imbricati, per antbesin patentes revoluti. Stamina 5, medium tubum versus affixa, 

 exserta, filamentis obcordatis expansis inflatis basi annulo villoso cinctis ; anthera oblongo- 

 lineares, longe acuminata, erecta, conniventes, cohserentes. Ovarii lobi 4, distincti, 

 gynobasi parva plan;e impositi ; stylus filifonnis erectus, stigmate subintegro ; ovula 

 erecta. Nuculas 4, erecta, acuta, angulata, verrucosa, areola basalari. Semina recta; 

 embryo rectus, cotyledonibus ovatis crassis plano-convexis, radicula supera. — Herba 

 canescens, setoso-luspida pilis simplicibus. Folia alterna. Cymse scorpioidea terminales, 

 bracteis parvis inferioribus foliaceis. Flores azurei, pedicellati. 



A monotypic endemic genus founded chiefly on characters of the an- 

 droecium. Each filament has an inflated sac attached to its back. One 

 might take these at first for corolline scales, but they do not arise from the 

 corolla nor are they attached to it in any way, but are distinct expansions of 

 the filaments to which the anthers are dorsally affixed by a small area. The 

 true anther lobes are very short, but have long apical appendages.
