Dr. John H. Bamhart recently called our attention to a number of cactus names 

 published by St. Hilaire which have been overlooked by later writers. One of these, 

 Cactus hdcrocladus St. Hilaire (Voy. Rio de Janeiro and Minas Geraes 2: 103. 1830) 

 seems to belong here, as the following free translation would indicate: 



''Another cactus, which I have already seen near Rio de 



Jan 



its trunk, which grows more slender from the base to the 

 summit, is covered with fascicles of spines arranged in a 

 quincunx, and it shows various stages of verticillate, hori- 

 zontal, rounded branches, to the number of seven in each 

 whorl; these branches, like those of the spruce tree, grow 

 shorter toward the summit of the plant, and they bear sec- 

 ondary branches, flattened and oval-oblong, which may in a 

 certain sense be taken as leaves."
