The account of this natural order in the Flora of British India 
(i. 116-119) was published 23 years ago (May 1872). Since that 
date a number of forms new to the Indian area have been communica¬ 
ted to the Calcutta Herbarium from the various frontiers of the 
Empire. Some of these require.to be added to the Indian Flora, not 
because they were unknown when the first volume of the Flora of 
British India was published—a few of them as a matter of fact are 
included in the Flora Indica published by Drs. Hooker and Thomson 
in 1855, which included in its purview the area beyond the north-west 
frontier comprising Beluchistan and Afghanistan that is excluded from 
the scope of the later work—but owing to extension of Indian territory 
towards the north-west during the past quarter of a century. In the 
present paper it is proposed to provide diagnoses of those forms in as 
nearly as may be the style of the diagnoses in the Flora of British India ; 
to obviate the possibility of confusion between the forms now described 
and those given in the Flora, keys have been prepared showing the 
relationships of all the Indian species in each genus. 
To assure himself of the probable validity of the species here pro¬ 
posed as new, and of the accuracy of the nomenclature of those previ¬ 
ously described, the writer has compared examples of each with the 
material of the order contained in a number of European collections. 
He has also had the advantage of the use of the material in Herb. 
Saharanpur kindly placed at his disposal by Mr. Huthie, that in Herb. 
Zurich kindly lent by his friend Prof. Schinz and that in the private 
collection of Mr. 0. B. Clarke kindly lent by its owner. For facilities 
in consulting^tlie public Herbaria at Kew, the British Museum, Paris and 
Geneva, the writer has to thank Mr. Dyer, Mr. Carruthers, M. Ed. Bureau, 
and Dr. J. Mueller respectively ; while for permission to study the mate¬ 
rial in their magnificent private collections, he is deeply indebted to M* 
Casimir de Candolle and M. Barbey-Boissier of Geneva, and to M. Drake 
del Castillo of Paris. And for assistance and advice most ungrudg¬ 
ingly given during his study of these Indian species, the writer would 
wish to thank many friends, but more especially M. Casimir de Can¬ 
dolle, Geneva; M. Ad. Franchet, Paris; Dr. Batalin, St. Petersburg; 
and Surgn.-Captn. Cummins, Army Medical Staff. 
The limitation of genera, at all times a subject of discussion, is 
particularly perplexing among Thalamifloral orders ; the difficulties 
that beset the student of Papaveracese in particular are many and 
great. A complete review of these difficulties could only be appropriate
