Of this species Mr. Potts hrougbt me, in 1S50, two large plants, 21 feet high and li feet thick, weigh- 
ing each upwards of 200 lbs. I calculated the spines on eacli plant to be at least 8300. Both plants died soon 
after I got them. A plant not disaimibir, but of gigantic proportions, more than man's beight, grows in 
California. Captain KeUett took two plants from California to Oahu, where tliey remained with the Eng- 
lish consul. The Captain gave me some seeds, which however did not vegetate ; it was smaller than that 
of my plants. It would appear that there are, in the neighbourhood of Chihuahua, two distinct species; 
the seeds which Mr. Potts sent me differed in size from those contained in the fruit which crowned one of 
my plants, and the seedlings obtained differ altogether.

This plant has come from various parts of ^Mexico, and has frequently flowered in the Kew Gardens. 
The flower is pale yellow ; that of E. longihamatus, according to buds, which however have not opened, 
would seem to be reddish. Received 1845.
