the extreme forms cau be shown, while without the aid of such 

 a series the limits of this species camiot be accurately deter- 

 mined, nor the error of raising varieties to the rank of species be 



avoided. 



The array of synonyms I have given, is partly owing to Nees 

 von Esenbeck's views of the limits of species, but principally to 

 this species being at the time he wrote very imperfectly repre- 

 sented in the herbaria he examined. In a species so abundant as 

 this is, scarcely any two plants are identically alike, imless growing 

 within a short distance of each other. In the shady roadsides 

 of Bengal, the Malayan peninsula, and Java, the plant becomes 

 the S. sarmentosa, Zoll., while on the dry rocky hillsides of 

 Southern India, Parasnath, and some portions of the Himalaya, 

 forms are developed to which the names _Z2. crinita, S. molUssma, 

 and JB. rotundifolia have been given by botanists. I believe 

 that R. glandulosa, JR. adenostachya^ H. ohtiisa, and JR. media 

 will probably require to be added to the synonyms I have cited ; 

 but as yet I have not seen authentic specimens of these so- 

 called species. 



I find it be quite impossible even to indicate any varieties m 

 so variable a species.
