that it was the Zamia tridendata of Willdenow, but that plant 

 (now Encephalartus, Lehin.), as shown by the figure in Miquel's 

 work, 1. c., taken from Willdenow's original specimen in his her- 

 barium, is totally distinct, and more like a Macrozamia than an 

 Encephalartus. After the most careful examination of our plant, 

 I can only come to the conclusion that it is one of the many 

 varieties of E. horridus, with a great tendency to have, on the 

 inferior margin of the pinnules, two large spinescent lacinia? 

 which, in conjunction with terminal spines, justify the application 

 ot the term var. trispinosa.
