ILLUSTRATIONS OF INDIAN BOTANY. 



Remarks ox Genera and Species. My examination of species of this order, has been 

 on too limited a scale to admit of my having much to say under this head. A few new species 

 and one new genus have been added to the family, accompanied with figures, in my Icones.

well as for the purpose of showing the relationship existing between this and the two preceding 

 orders, I shall, in a supplementary plate, give analyses of some of the genera, partly taken from 

 my own dissections, partly copied from those of others. It may be proper here to remark that 

 the difference between Chirita and Didymocarpus, is very slight, so slight indeed that it is 

 most difficult to distinguish them, resting as it does entirely on the stigma. For some time 

 I felt doubtful whether I ought to place the following species in the one or other genus, but 

 think that it accords better with the latter, to which therefore I refer it. In the supplementary 

 plate I have given analytical illustrations of 12 genera, which I shall simply name; the explana- 

 tion of one in a great measure serving for all. 



EXPLANATION OF PLATE 159. 



Didymocarpus Griffithii (R. W.), herbaceous, erect, 

 4-sidea, furrowed oa the sides; angles roundish blunt, 



fiilose above : leaves o.vate, acuminate, crenato-serrated, 

 ongish petioled, pilose on both sides : peduncles axillary, 

 longer than the petiols, cymosely 5-7-flowered ; flowers 

 longish pedicelled : calyx deeply 5-parted, segments Ian- 

 ceolate: corolla tubxilar,five-lobed: stamens didynamous, 

 the fifth rudimentary one sometimes wanting, stigma two- 

 lobed. Leaves, including the petiol, 4 to 6 inches long 

 by 1^ broad at the base ; cymes furnished witii a pair 

 of lanceolate bracts at each division : tube of the corolla, 

 hairy without Khassya, Griffith. This appears a very 

 handsome species and quite new.
