or sKghtly enlarged Btigmatiferous extremity. In the internal angle 

 of each cell is inserted a descending anatropous ovule,^ the micropyle 

 of which is primarily directed upwards and inwards." The fruit, 

 around which persist the little developed sepals, is a drupe the 

 putamens of which, four to six in number, enclose each a descending 

 compressed seed with a hard albumen near the summit of which is a 

 small embryo with superior radicle. The only species ' known is a 

 small perennial herb with musk-like odour, a thin fleshy stock creeping 

 under the soil and bearing alternate scales, then 3-5-foliolate or 2-3- 

 ternatisect leaves, which in spring expand in the air and have a long 

 petiole, dilated below to a fleshy sheath. The flowers terminate a 

 small axis bearing two opposite, 3-foliolate-lobed leaves, and are 

 united in a sort of small few-flowered capitule (?), the terminal flower 

 of which is tetramerous, more rarely pentamerous, and the lateral 

 flowers pentamerous, more rarely hexamerous. This plant inhabits 

 the cold and temperate countries of the northern hemisphere. 



B. DE JussiBu, in 1759, admitted an Order Rubiacece* in which he 

 included Lippia. Adanson gave to the same genus the name of 

 Aparina.^ A. L. de Jussieu® resumed the name of Ruhiacece for an 

 Order in which he placed Bellonia. In 1829, AcH. Richard pre- 

 sented to the Academy of Sciences a Memoir on the family of the 

 Ruhiacece which was not published till later,' when A. P. de Candolle 

 had given a monograph of this family in the Prodromus.^ Being 

 considered a difficult study, it remained for a long time without 

 Comprehensive treatment. Endlioher * restricted himself to repro- 

 ducing, with some very small additions, the researches of his two 

 predecessors. He admitted thirteen tribes of Ruhiacece with three 

 hundred and twenty genera, exclusive of a score of doubtful ones. 

 LiNDLEY divided the Ruhiacece into two Orders, Ciinchoniacece ^° and 

 Galiacece,^^ interposing Caprifoliacece.^'^ The latter, in our opinion,'*
