the tube is cylindrical, 1 line in diameter; the disk is seated 

 near its base : the pedicel is only line long in the flower, and 

 2 lines in fruit. The 3-lobed capsule, supported on the cupular 

 remnant of the calyx, is 2J lines in diameter*.

This is a delicate and slender species. The specimen above 

 quoted is a mere fragment, 6 or 8 inches in length, originally 

 contributed by Cavanilles to the younger Linnaeus, whose herba- 

 rium passed into that of Sir Jas. Smith (now the property of the 

 Linnsean Society). In habit it greatly resembles some of the 

 species of Discaria, for which, at first sight, it might be mistaken. 

 Its primary spines are very slender, almost acicular, of a pale 

 green colour, pubescent, and about 2 inches long ; the secondary 

 spines, still more slender, are from 4 to 9 lines in length ; the 

 tertiary spinelets are only a line long : its filiform peduncles are 

 1| line long, the very slender tube of the calyx, including the 

 segments, is 2 lines long, the tube being 5 line in diameter f.
