of PorvGaLa myrtifolia, a far larger shrub with greatly 
wider obovately oblong round-topped leaves, racemes with 
a much longer axis or rachis, paler coloured flowers, a 
shorter stigma, and latent ale with villous points, or, when 
these ale are confluent for their whole length with the 
stamineous tube on which they stand (as is sometimes the 
case, and then their presence is marked merely by a promi- 
nencé with a corresponding contour), a villous spot where 
the point of the ale would have been had these been de- 
tached. 
We do not find that the latent ale, of which we have 
spoken, have been previously noticed in this genus by 
any one, but that its corolla has been always regarded as 
tripetalous. In three species from the Cape of Good Hope 
usine which we have examined, two latent petals, termed 
ale from their analogy to those of the flower of the pa- 
pilionaceous Leguminosæ, and which alternate on each side 
the corolla with the lower segments of the calyx, have 
certainly been present in a more or less perfect form; and 
always in such state as to require, in our opinion, the co- 
rolla to be considered as pentapetalous rather than tri- 
petalous. 
In the corolla of Porycara the papilionaceous type dif- 
fers from that of the Leguminose, in having a dipetalous 
vexillum and monopetalous carina, instead of a mono- 
petalous vexillum and dipetalous carina as there. 
On mentioning the above circumstance to Mr. Brown, 
he pointed out to us the observation on the genus SECURI- 
DACA, to be found in the extract from his work in the pre- 
ceding article.
