DIDYNAMIA. 433 



tram, Adonis, Ranunculus, Trolfim 9 HeU 

 leborus and Caltha, all conspicuous in our 

 gardens or meadows, which, with a few 

 less familiar, close this class. 



Nothing can be more injudicious than 

 uniting these two last classes, as some in- 

 experienced authors have done. They are 

 immutably distinct in nature and charac- 

 ters, whether we call the part which imme- 

 diately bears the stamens in the Icosandria 

 a calyx, with most botanists, or a recep- 

 tacle, with Mr. Salisbury in the 3th vol. 

 of the Linnsean Society's Transactions, 

 where, among many things which I wish 

 had been omitted, are some good remarks 

 concerning the distinction between calyx 

 and corolla. This the writer in question 

 considers as decided in doubtful cases by 

 the latter sometimes bearing the stamens, 

 which the former, in his opinion, never 

 really does. 



Class 14. Didynamia. Stamens 2 long and 

 2 short. Orders 2, each on the whole 

 very natural. 



1. Gymnospermia. Seeds naked, in the bot-
