collections (Schultes & Cabrera 17619 of September 25, 
1952, and 17638 of September 25-26, 1952) differ strongly 
from the isotype and topotypes of the original species, 
as the following table of comparison will show. The third, 
a fruiting collection (Schultes & Cabrera 15910 of March 
2, 1952) has the dark-colored branchlets, smaller gradate 
and more numerous sepals of Lorostemon bombaciflorum, 
and, as in that species, lacks the conspicuous torus-like 
peduncle between the bractioles and calyx. The leaves, 
however, are oblong and not obovate as in Lorostemon 
bombaciflorum. Schultes & Cabrera 15910 is tentatively 
assigned to Lorostemon bombaciflorum until flowering 
material of it is collected.
