AND THEIR SYSTEMATICAL ARRANGEMENT. UJ 



of which are particularly large, as for instance, 

 Limodorum Tankervillice, the style, when opened 

 longitudinally, distinctly shows slender ducts, run- 

 ning from the upper end of the stigma down to 

 the germ ; and when put into water and slightly 

 pressed, the absorbed fluid soon appears to issue 

 out of the stigma. 



The fruit, of which Gaertner has given a com-

 an unilocular capsule, with three projecting angles, 

 along which it at last opens, with three valves, con-
