Having been favoured by the Prefident with a fight of the plants 

 in the Linnxan herbarium, it was with great pleafure I found there 

 one of this fpecies: it was inferibed by Linnaeus, Orabanc.be major, 

 and was given him by Loefling; moft probably it was one of thofe 

 from the King of Spain's garden at Aranjuez, found at the roots of 

 ' elms, which Loefling has defcribed among his Plants Hi/panicle 

 'rariores. That it forms a diftinct fpecies there can now be very 

 little doubt : the figure in EngUJh Botany is taken from one of my 

 fpecimens — it represents the calyx perfectly well, but not the ftig- 

 mata. It is frequently to be found with a much longer fpike ; in 

 which cafe the flowers are not only more numerous, but are much 

 clofer fet than in the figure. From its growing fo very copiou fly 

 among clover, I am of opinion it is the fame which Dr. Turner 

 noticed as being fo pernicious to it. None of the other old Her- 

 balifts have mentioned it, nor has it been introduced into any of our 

 Britifh Floras, if we. except Hudfon, who is thought to have it in his 



firft:
