ribbed and five-lobed at the base; more different from any 
other figure is his of the tube of the calyx, which is repre- 
sented as perfectly globose, crowned with a lobed limb, 
the whole resembling the inferior ovary and calyx of a 
Rubiaceous plant. G. Don describes the corolla-limb as 
five-angled; Meissner does not, but says that the raceme 
is a scorpioid cyme, which it appears to be on a hasty 
glance, but it is only at first slightly recurved, with secund 
flowers. Micheli’s M. cordata represents a very weak, 
undeveloped state of the species, with all the leaves cor-_ 
date and undivided, and the very short racemes very few- 
flowered. 
I have retained the generic name of Mina for this plant, 
whilst recognizing its very close affinity with the section 
Quamoclit of Ipomaa, from which it differs in inflorescence, 
in the ampulliform limb of the corolla narrowed upwards 
to the mouth, and in the very small lobes of the limb. 
Meissner reduced Mina to Ipomea, and being obliged to 
discard the specific name (lobata) as being preoccupied, 
gave that of versicolor as descriptive of the change of 
colour in the corolla from red to yellow. 
Mina lobata is a native of Mexico, where it is frequently 
cultivated. There are specimens in the Kew Herbarium 
from Mr. Parkinson, late Consul-General in Mexico; from 
San Luis, Potosi, collected by Schaffner, and from a 
garden in Orizaba, by Botteri. Prof. Micheli’s plant 
(M. cordata) was raised from seeds collected in the States of 
~ Michoacan and Guerrero, in Western Mexico, whether 
from an indigenous plant is not stated.
