nlJ^S' is .a small tree, witb ratbcr virgate brancbes and an 



blanch c ts having an ap.culate termination; the branches arc 

 quite glabrous ; the spines, | to l.| inch long, arc always articu- 

 atcd in the midd e, and there floriterous; the fertile branchlcts 

 that spring from below them bear an abundance of tlowcrs and 

 leaves, with the axds approximated, so that the inflorescence 

 appears somewhat spicated ; these branchlcts, though sometimes 

 much longer, seldom exceed half an inch in length, bcarmo- 

 in each node two opposite sets of three fasciculated llowcrs and 

 two opposite leaves; the leaves are from 6 to 9 lines Ion- 

 3 lines broad on a petiole 1 line in length; those of the mam 

 branches are 1 inch long, and half an inch broad, the nuu-ins 

 generally rcvolutc, with crcnatcd, almost obsolete teeth, tnd 

 yel owish Ihe peduncles are nearly 2 lines long; the broad 

 and urceolate tube of the calyx is 1 line long, its Segments .and 

 erect stamens J bnc in length; the small bypogynous disk 

 adna te to it is sbghtly concave, green, smooth, lleshv, with a 

 raised undulating margin, and is half as broad attain as' the verv 

 pdosc ovary which it supports. The 3-coccou.s IVuit is about 

 2 lines in diameter, and pdosc: when the cocci spring out of 

 heir bed, which they do with a noise and much elastfc force 

 their persistent cup is seen to be formed of three distinct and
