 « Petals inversely heart-shaped, shorter than the taper-pointed cahx 

 which is nearly as long as the capsule," Sm. — ln comparing this 

 and the preceding species, it may be proper to state that by the lowest 

 bracteas we mean the pair of leaves at that fork where the first pedicel 

 appears: in the three species already noticed the bracteas become 

 suddenly smaller, whereas in C. tetrandrum tliey remain about as larn-e 

 as the leaves, and similar to them, after the cyme has been repeatedly 

 forked.
