Clausena (including Coohia). 



To this genus, established by Bunnaun in his ' Flora Indica,' 

 Wight and Arnott have correctly referred several Iudian species,de- 

 scribed by Roxburgh under the genus Amy r is. The typical Clau- 

 sencd are characterized by pinnate, often more or less hairy leaves, 

 tetramerous flowers disposed in cymose clusters in paniculate or 

 racemose, terminal or axillary inflorescences, and 1- or 2-seeded 

 berries. A few species vary with pentamerous flowers. As I 

 consider the usually pentamerous symmetry and succulent, often 

 5-seeded berries of the genus Coohia of Sonnerat, to be in them- 

 selves insufficient to constitute valid grounds of generic distinc- 

 tion, I have united it, as a section, with Clausena. "With this 

 genus, as hitherto maintained, it agrees entirely in other respects, 

 and especially with those species having a terminal, much-branched 

 inflorescence. The arching concavity of the filaments is perhaps 

 not so marked in Coohia as in Clausena. My grounds for in- 

 cluding Piplostylis in Clausena I have stated above. 



The genus Aulacium of Loureiro, referred to Coohia by DeCan- 



dolle (Prod. i. 537), must be a dubious associate of this group. I 



' understand the leaves, from Loureiro's description, to be simple ; 



I have not seen anything like the 4-sulcate petals which he ascribes 



to his genus. 



GrLYCOSMIS. 



Based by Correa de Serra on two species referred by Retzius 

 and Dr. Roxburgh to the genus Limonia, and figured by the latter 

 in his ' Plants of Coromandel,' vol. i. tt. 84, 85. The genus Gly- 

 cosmis I consider a natural one. It is mainly characterized by 

 small flowers with pentamerous outer whorls, the calyx 5-partite, 

 with broadly imbricate lobes, the very short and thick persistent 

 style directly continuous with the ovary and sometimes of almost 

 equal diameter, the cells of the ovary usually 5 or 3 (though some- 

 times it is found with 4 or 2), each cell containing a solitary ovule. 

 The leaves consist usually of several, but not numerous, leaflets, 

 which are glabrous and more or less coriaceous in texture. The 

 axillary cymose iuflorescence is commonly small. In one or two 

 forms we may find 1-, 3-, or 5-foliolate leaves on the same branch. 

 Some varieties of G. pentaphylla are particularly variable in this 

 respect ; in one of these, growing in Khasia and Assam, the leaf- 

 lets, when solitary, are often unusually large, sometimes 10 inches 

 in length. Glycosmis pentaphylla, as I have endeavoured to
