any Gratiolee, and as well as the form of the corolla, appear 
to me to assimilate the plant much more to some of the 
Salpiglossidez, and especially to the Salpiglossis prostrata, 
Hook. et Arn. and some other species from the West Coast of 
America, which probably form a new genus. Like other 
Salpiglossidez it comes near the capsular Solanez, and the 
corolla is very nearly that of Fabiana. 
The following are the characters of the. species I am 
acquainted with of Aptosimum, and of another genus.also 
from the Cape, which is closely allied to it and belongs 
likewise to the tribe of Salpiglossideze.
