of most temperate or warm rcgious but extratropical, some belong to 

 intratropical South America.^ 



Z. trigtjnum^' a plaut of Eastern India, and two neigh- 

 bouring species have served to form the small genus Rebiwardtia^^ 

 which arrangement, however, is questionable, as they are only dis- 

 tinguished by theii- hypogynous often unequal glands and theii- 

 carpels three or foiu* in number, instead of five as in the Flaxes.- — 

 They are shi-ubs or uudershrubs, with alternate leaves and axillary 

 flowers, solitary or in cymes, more rarely in terminal corymbiform 

 cymes ; we shall only make them a section of the genus Linum. 



In Linum catharticum^^ the leaves are opposite and the cymes 

 more regular than in most of the other species ; the genus Catharto- 

 linum,^ was made of them, but it has not been kept distinct. 



In L. Radioing'' a very small French annual species, also distin- 

 guished as a genus under the name Radiola^"' the organs of vegeta- 

 tion are disposed in the same way, but the flowers are tetramerous, 

 and the sepals are generally tridentate : characters to which we no 

 longer give generic value. 



Animdenia^ consisting of perennial herbs from the Himalayas, 

 have nearly the flowers,''' with trimerous gynœceum and unequal 

 glands of Rcinwardtia. One of the glands is often miich more 

 developed than the others. The fruit is said to be membranous ; the 

 sepals are dissimilar, the two interior remaining glabrous while the
