This was sent to the Horticultural Society from the Gdttingen Garden, under 

 the name of S. pubescens : it appears to be a mere variety of S. germanica, with 

 thicker leaves than usual. 



It is a hardy perennial, flowering from June to the end of August. 



Mr. Bentham having kindly supplied us with a continuation of his very 

 valuable and interesting characters of the genera of Labiatee, we gladly take this 

 opportunity of printing it, being desirous that not a day should be lost in putting 

 Botanists in possession of information which is of such great importance to them. 



J. L. 



" This genus, which appears to be spread over nearly the whole of the globe, is a numerous 

 and very natural one, and consequently difficult in regard to the distinction of its species. The 

 generic character brings it nearest to Betonica and to Chaiturus : it diifers from the former 

 chieily by the shorter tube of the corolla, and the divaricate cells of the anthers. Chaiturus is 

 easily distinguished fi-om Stachys by its habit and inflorescence ; yet the erect position of the 

 upper lip of the corolla, and the shorter stamina scarcely protruding from the tube of the corolla, 

 are the only characters I have been able to find. 



The S. lavandulsefolia has been established as a separate genus, under the name of Zietenia, by 

 Gleditsch, who, according to Persoon {Ench. 2. p. 124), distinguishes it from Stachys by the 

 long subulate laciniae of the calyx, and the abortion of three of the nuts ; but neither of these 

 characters appears to me sufficiently important for the generic separation of plants otherwise 

 resembling each other. 



The genus Stachys belongs to the Labiatae with ascendent stamina, which I should propose 

 to divide into four tribes, the Ajugoideee, Monardece, Nepetece, and Prasiea ; the remainder of 

 the Labiatae, those with declinate stamina, forming a single tribe, the Ocymoidew. I now 

 proceed to continue the enumeration of the genera, as commenced in the last Number of 

 the Register., giving the characters of those which I have been able to examine myself, and 

 inserting the names only of such as I am no otherwise acquainted with than by the descriptions 

 of authors.
