Professor Zuccarini first described the species in his ac- 
count of the new plants cultivated in the Botanical Garden of 
Munich, where it was raised from Mexican seeds collected by 
Count Karwinski. The supply, from which the plants now 
in our collections have been obtained, has however been fur- 
nished by the Horticultural Society, to whom seeds were sent 
by Mr. Hartweg, who found the species in Mexico, in a place 
called the Banco. 
Those who are students of the British Flora will not fail 
to recognise in this gay Lopezia, the same features as those 
of our own little Enchanter’s Nightshade, with which it is 
associated in a natural arrangement. In this plant the second 
stamen of Circa is converted into a spoon-shaped petal.
