of most temperate or warm regions but extra tro2)ical, some belong to 

 iutratropical South America.^ 



Z. trujjjnum^' a plant of Eastern India, and two neigh- 

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

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

 tinguished by thcii' hypogynous often unequ.al glands and theii' 

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

 They are shi'ubs or undershriibs, 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 Limim. 



In Liuum cathartlcum* the leaves are opposite and the cymes 

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

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



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

 guished as a genus under the name RaJiola,"' the organs of vegeta- 

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

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

 longer give generic value. 



Jnisadcnia,^ consisting of perennial herbs from the Himalayas, 

 have nearly the flowers,'-* with trimerous gynteceum and unequal 

 glands of Reimvardtia. 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
