LINAGES. 45 



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

 intratropical Soutb America.^ 



L. trigynum^ a plant of Eastern India, and two neigh- 

 bouring species have served to form the small genus ReinwardUa^ 

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

 tinguished by their hypogynous often unequal glands and their 

 carpels three or four iu number, instead of five as in the Flaxes. — 

 They are shrubs or undershrubs, 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 lAnum 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. Radiola,^ a very small Trench 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. 



Anisadenia^ consisting of perennial herbs from the Himalayas, 

 have nearly the flowers,^ with trimerous gynseoeum and unequal 

 glands of Reinwardtia. One of the glands is often much more 

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

 sepals are dissimilar, the two interior remaining glabrous while the
