1. R. caule subherbaceo fistuloso viridi pulverulento, stigmati- 



bus bifidis. 

 Ricinus communis. Willd. Sp. PL iv. 564? 

 Ricinus albus sylvestris. Humph. Amb. iv. 90. 

 Cit Avanacu cortice viridi. Hort. Mai. ii. 57- 



2. R. caule subherbaceo rubro pulverulento, stigmatibus bipar- 



titis, foliis lividis. 

 Ricinus lividus. Willd. Sp. PL iv. 565 ? 

 Ricinus albus domesticus. Herb. Amb. iv. 90. 

 Cit Avanacu cortice rubro. Hort. Mai. ii. 57. 



The other two varieties by the natives are called Pat (leaf) 

 Arinda, because they are chiefly cultivated for their leaves, on 

 which a large kind of silk- worm* is reared for spinning a coarse 

 silk called Arindi. On these accounts they are usually planted 

 in hedges round the huts of those who rear the worms ; and 

 being allowed to stand for years, acquire a considerable size. 



3. R. caule lignoso solido viridi. 



Ricinus viridis. Willd. Sp. PL iv. 564? (exclusis synonymis). 



4. R. caule lignoso solido rubro laevi, petiolis medio et apice 



glandulosis, stigmatibus bipartitis, foliis lividis. 



Ricinus africanus. Willd. Sp. PL iv. 564 ? 



Ricinus ruber. Herb. Amb. iv. 97. t. 41. 



Pandi Avanacu. Hort. Mai. ii. 60. " a Cit Avanacu in eo 

 tantum differt, quod altius assurgat, quodque stipitibus 

 et ramis est valde rubris seu miniatis et nitentibus." 



It can scarcely, I think, be supposed, that the trifling diffe- 

 rence between stigma bifidum and s. bipartitum, in a plant much 

 and long cultivated, can be considered as sufficient to establish 

 a distinction of species.
