position of its lobes, characters good enough were they constantly 
found in one and never in another. Such, however, is not the case. 
For instance, the delimited Echeveria rests primarily upon its 
5-angled corolla, but to Dudleya have been assigned species showing 
this character to some degree. In similar manner, the corolla of 
Gormania is said to be campanulate with spreading lobes, while in 
Dudleya it is tubular and the lobes erect. But in many of the 
species of Dudleya the tips of the lobes, at any rate, are spreading, 
while corollas occur in both to which the expression short-tubular 
or narrowly-campanulate might be‘ applied with equal appropri- 
ateness. Thus, it appears that through the corolla of Gormania, at 
least, we are back to typical Echeveria. Since the characters thus 
overlap, it would seem best to refer all the species to the oldest 
genus, in accordance with which view some of the representative 
ones are here transferred.
