The present plant will be seen at once to be very closely 
lied to the Convorvutus Nil of Linneus, excellently 
ggured in the 188th plate of Curtis's Botanical Magazine. 
rphe principal mark which appears to distinguish it, is that 
prre the segments of the limb of the corolla are circular and 
xy shallow, while in Nil they are deep and tapered into a 
point 5 the colour is likewise much paler in our plant and 
t}'¢ foliage more deeply divided. Slight as these differences 
lay appear, they have been found by Dr. Roxburgh, after a 
pntinued cultivation of the two in the Botanic Garden at 
aleutta, to be constant, and one plant has never been per- 
sived to make the least advance towards the other by any 
iriation in these respects; so that we have not hesitated to 
eer the two distinct, after the example of Dr. Roxburgh.
