names. This led to the discovery that the names were transposed in 

 many instances, and made the records thus entirely untrustworthy, a state of 

 affairs that is frequently responsible for unintentional substitution and 

 adulteration in the case of many other articles. This attempt was there- 

 fore abandoned and seeds were obtained from every available district for 

 planting. From these 139 different lots were cultivated, and the plants 

 carefully studied and compared at every stage of their growth. The 

 botanical literature and the history of the origin and cultivation of the 

 forms were exhaustively studied. In reaching his conclusions, the author 

 held himself entirely free from restraint by the opinions of his predecessors 

 when the latter were clearly at variance with his own observations. The 

 primary object of the study being agricultural, first attention was given to 

 defining accurately the native names, which are given precedence in the 

 classification, the botanical equivalents following. 



The genus Si?iapis is not maintained distinct from Brassica. Priority of 

 use is maintained as fixing both the common and botanical names. Places 

 of publication are cited, but the dates are omitted. Little attempt appears 

 to have been made to discriminate between nature's species and those which 

 have resulted from cultivation, provided the specific characters are clear. 

 One of the most important, and not a little surprising, facts established 

 is that not the slightest tendency to intergrading between the species ex- 

 ists. The belief to the contrary is due to the confusion in application of 

 the names above noted. Neither the black nor white mustard, as known 

 to us, are there grown. 



The species, as worked out by Dr. Prain, are as follows : Brassica ru- 

 gosa (Roxb. ) Prain (= Sinapis rugosa Roxb.) is the Pasai. It is an annual, 

 forming first a loose cabbage-like head and then shooting into bloom. 



B. rugosa cuneifolia (Roxb.) Prain (= Sinapis cuneifolia Roxb.) is the 

 Lahi Sag. It differs from the former chiefly in not forming a cabbage be- 

 fore flowering. 



B. juncea (L,.) Hook. f. et Thorns. (= Sinapis junce a L,. ) is the Asi-Rai 

 or Italian mustard. It has the same habit of growth as the last, and ex- 

 hibits a number of varieties. 



B. campestris L,. is the Colza or Chitagong Mustard. It sends up many 

 tall branches from a cluster of radical leaves. 



B. campestris Sarson Prain is the Sarson or Indian Colza. It is a tall 

 annual, its stem growing continuously and branching at the top only. 



B. Wapus dichotoma (Roxb.) Prain (= Sinapis dichotoma Roxb.) is the 

 Tori or Indian Rape. It is a much-branched annual, not so tall as the others. 



B. Wapus esculenta DC. is the Bhutia Moola, of similar habit to the last. 



B. Chinensis L,. is the China Cabbage or China Gobi. This forms first 

 a loose cabbage. A government order has been issued that it be cultivated 

 in all jail-gardens as a pot-herb, because it is one of the very few things 

 which can be made to jdeld a crop during the rainy season. H. H. R.
