30 FLORA IN Die A. [Eanunculacecs, 



The Indian forms, so far as hitherto observed, belong to the state called Fanto- 

 thrix, in which the leaves are all submerged and divided into capillary segments, but 

 not so much elongated as in H, peticedanif alius, AU,, which Schlechtendal considers 

 the only distinct species. This plant is not very common in India, lakes and tran- 

 quilly flowing streams being of rare occurrence in the exterior Himalaya, though fre- 

 quent in the inner parts of the chain and iu Tibet, where, accordingly, our plant is very 

 generally difl'used. In the plains it is confined to the extreme north, where it will 

 probably be found skirting the base of the Himalaya in aU parts of the Panjab. It is 

 usual to divide this species into several, characterized by the absence or presence of 

 the reniform leaves, and by variations in the size and shape of the multifid ones, as 

 well as by the hairiness or smoothness of the plant and carpels ; but we quite agree 

 with Scringe, that all these forms are states of one very variable species, to which 

 we are quite wilhng, with that very accurate observer, to unite R. hederaceus and 

 R. iriijtartitus.
