The above description is entirely drawn up from the 
specimen figured, which has been growing in the Temperate 
House, Kew, at least twenty-five years, and is now the 
largest of which the dimensions are on record. It is 
probably the same one that is figured in the “ Refugium 
Botanicum,” and, if so, it was previously in the Succulent 
House. This species is one of the handsomest of the 
genus, but it is not quite hardy. The date of its introduc- 
tion into this country is uncertain, yet it must have been 
long before 1373, when it was first figured, and then also 
from a plant that flowered at Kew. At that time it had a 
trunk from five to six feet high. 
Dr. W. Trelease, Director of the Missouri Botanic 
Garden, who has more fully than any other botanist 
described and illustrated the genus Yucca and its allies, 
identifies Y. guatemalensis, Baker, with a plant included by 
Regel (Gartenfl. vol. vili. 1859, p. 35) under Y. aloifolia.
