161 MR. N. E. BROWN OX THE 



In the following descriptions I have arranged them (and num- 

 bered in brackets) in the same order thev are described in Thuu- 

 berg's ' Flora Capensis/ 



% I take this opportunity to gratefuliy acknowledge the numerous 

 obligations 1 am under to Prof. Oliver for the kindness with 

 which he has always assisted me in cases of difficulty, not only as 

 regards the subjects of this paper, but on many other occasions 

 when difficulties have arisen in working out this somewhat trou- 

 blesome group. 



TincHOCAULOx, N. E. Br., gen. now 



* 



Calyx 5-partitus, basi intus 5-squamatus, segraentis acuminatis. Co- 

 rolla patelliforrais aliquando tubo brevi instructa, alte 5-fida; lobis 

 late ovatis, cuspidatis, valvatis. Corona duplex, breviter stipitata ; ex- 

 terior alte 5-loba, lobis basi breviter connatis alteque bipartitis, seg- 

 mentis valde divarieato-arcuatis ; interioris lobi 5, ligulati, coronse 

 exteriore antherisque basi adnati, apice obtusi liberi incumbentes. 

 Caules humiles, crasso-carnosi, multangulati, angulis tuberculatis, 

 tuberculis aculeatis. Flores parvi inter angulos prope ramorum sum- 

 mum subsolitarii, brevissime pedicellati. 



Species 2, Africae australis incolap. 



As a genus, this will stand next to Hooclia, of which it has the 

 habit ; but differs from that genus as follows : — The corolla is 

 very much smaller and deeply 5-lobed instead of truncate, and 

 the lobes of the outer corona, instead of being shortly bifid, are 

 deeply bipartite, and the two narrow segments so formed are 

 horizontal and widely divergent -curved, the apex of one seg- 

 ment of one lobe touching, or nearly so, the apex of one seg- 

 ment of the adjacent lobe, so as to present the appearance of 

 a pair of mandibles, as is noticed by Thunberg.
