Catycantuus fertilis differs from C. floridus, with which 
it is often confounded in the gardens, in having flat scabrous 
oblong leaves with an acumen, in being glaucous and nearly 
naked beneath, and in the colour of its almost scentless 
flowers. From C. levigatus the same characters equally 
distinguish it. It is right, however, to observe that the 
young leaves of the present plant have nearly the form of 
C. levigatus. We do not feel disposed to alter Walter's 
excellent name of fertilis for that of glaucus, which ori- 
ginated with Willdenow, and which has no pretensions to 
be retained: Andrews’s figure, which every body cites 
to this, seems to us decidedly Catycanruus lwvigatus. 
Native of the southern states of North America, and 
introduced, according to Hortus Kewensis, in 1806 by Mr. 
‘Lyon. 
M. de Jussieu in his elaborate dissertation on Moni- 
‘mie published in the 14th volume of the Annales du Mu- 
séum, has not suffered the affinity of Carycanruus to that 
order to escape his notice. Without however absolutely 
forming.a new order for the genus, he has only hinted at the 
propriety of so doing, when more individuals may have 
been discovered to increase it. But we cannot help think- 
ing, that when plants have such decided characters as the 
present, and when there is so little uncertainty with respect 
to their situation, it is much better to establish even a soli- 
tary individual as the type of an order, than to leave it 
amongst the mass of imperfectly known genera, which 
necessarily must always be appended to every natural sys- 
tem. — =. 
It is presumed that the characters given above are 
abundantly sufficient to distinguish Calycanthew, not only
