C. polifolia is most nearly allied to C sib yond, Mill. Arg. but 
is readily distinguished by its unwinged stems and its opaque leaves. 
It is noteworthy that, widely spread as C. polifolia is, there are no 
specimens from the particular area to which C. pterogona appears to 
be confined. The variety [3 teretifolia, recognised by Miiller, has 
no real existence, its origin being purely bibliographical. Sonder in 
1850 believed the species which is really C. pterogona to be C. 
polifolia, Jacq., and wrote up his material in accordance with this 
elief. Being thus left without a name for Jacquin’s species, 
Sonder took the latter to be a novelty which he described as C. tereti- 
folia, Asin C. pterogona, the leaves on young twigs of C. polifolia

red dice of the main-branches and we have the condition—for it 
is only a condition—to which Miiller in 1866 gave the specific name 
C. Meyeriana. The plant which Miiller in 1866 treated as 
cinerascens is & Som owhat robust and unusually rigid state of 
recog nition. On the other hand the reduction by Miiller of C. 
Scegiolia, Sond., to the position of a variety of C. poli Joye is very 
nearly as inconvenient as the proposed Scone: as @ species 
apart, of C. Meyeriana.

Though treated by Miiller as a variety of C. polifolia, Jacq., this 
seems a very distinct species with a somewhat limited and quite 
compact distribution. The localities Ganckwcratieted sil Stellenbosch, 
cited for C. brevifolia by Sonder, prove, on critical examination, to 
c 
tion not to belong to C. brevifolia, but to the ee of C. poli vole 
which Miiller termed C. Meyeriana. Sonder himself has made a 
suggestion that C. imbricata, E. Mey., might "abe ge be a form of 
C. brevifolia ; this suggestion Baillon ventured to give effect to. 
e now know that whatever its taxonomic relationship to 
brevifolia may be, C. imbricata, E, Mey. differs m orphologically
