deep groove, or hollow; these four keels converge, and in 
Some measure adhere together, which brings the side of 
the petals close so as to resemble a tube ; the upper part 
of the petals is narrow, first bending out a little, then 
Converging at their points. Nectary composed of four, lan- 
ceolate, yellow bodies, each sitting sessile on the apex 
of the keel of the petals, converging into one conical 
dome. Filaments none. Anthers eight, linear, lodged 
in the grooves formed by the keel of the petals, adhering 
their whole length, but their chief insertion is near the 
base. Germ superior, cordate, compressed, one-celled ;
