droughts have become more frequent and more severe, 
so that the Penguins do not thrive so luxuriantly as form- 
erly. The stem is about 5 inches in diameter, and not 
unfrequently 15 to 20 feet in height. The ridges are 
compressed and prominent, and armed with strong prickles 
in fascicules, the longest about an inch in length. Flowers 
sessile, rather more than three inches in length, externally 
erubescent. Sepals cohering, rounded and thickened, and 
fleshy at the apex. Petals erubescent. Stamens very 
numerous. Stigma 10-11-cleft. Berry size of a small 
pear, unarmed, crimson, opening at the apex, with 3 irre- 
gular clefts : seeds very numerous, black, somewhat kid- 
ney-shaped, truncated and excavated at one end, with the 
surface granular, imbedded in a rich crimson pulp.
