This is generally about three or four inches long, 

 narrow, linear, riblefs, fmooth, intire on the 

 edges, dichotomous, of a tough cartilaginous 

 fubftance, and olive colour. But the principal 

 character confills in this, that one fide of the 

 leaf is convex, the other channell'd through- 

 out. The channel is about one-eighth of an 

 inch wide. 



When the plant is in its fruflified ftate, the 

 fummits of the ramifications become dilated 

 and tumid for about the length of half an 

 inch, afiuming the appearance of veficles, 

 growing either bifid or in pairs, and covered 

 with fmall tubercles perforated in the centre ; 

 each of which tubercles is a capfule full of 

 minute feeds.
