336 SAVANILLA RHATANY. 



1865. of Krameria., Dr. Triana's determination of this plant as a 

 variety of Kr. Ixina appears to rue highly judicious, and far 

 safer than the introduction of a new specific name which the 

 receipt of further specimens would probably show to be unten- 

 able. I therefore accept Krameria Ixina, L. var. 13. granatensis 

 of Triana as the plant, the dried roots of which constitute the 

 drug known as Savanilla Rhatany. 



Krameria This form of Kr. Ixina has an extensive geographical range, 

 na> ' for besides occurring in the locality already mentioned, it exists 

 in Brazil, where it was collected in the island of Itamaraca 

 near Pernambuco by Gardner, who described it as " a shrub 

 about 3 feet high with long spreading branches." Another 

 specimen from the same botanist in the Hookerian Herbarium, 

 is labelled " common on dry hills in the Sertao of the pro- 

 vince of Ceara." 1 



ON PHARMACEUTICAL HERBARIA. 



(Pka rm a ceutische Herbarien. ) 



isee. THAT the well-educated pharmacist should possess a certain 



familiarity with the plants employed in medicine, and especially 

 with those indigenous to his own country, is a proposition upon 

 which there can scarcely be any difference of opinion. The 

 effort of mind and habits of observation brought into requisition 

 in order to obtain such knowledge are in no small degree bene- 

 ficial ; while the agreeable reminiscences called forth by an 

 inspection of the plants gathered in years long passed are such 

 as may well repay the trouble of forming and preserving an 

 herbarium. 



But it is not the formation of a general herbarium or even of 

 an herbarium of British plants, interesting and valuable though 

 they are, that I venture now to advocate. I wish rather to 

 point out the advantage to the student of being able to consult
