Obs. This is the Apocynum frutescens Linn., of which I 

 have examined the original specimen in Hermann's herba- 

 rium. The Quirivelia Zeylanica of Lamarck and Poiret, in 

 Encycl. method, botan. vol. 6, p. 42, considered by them as 

 Linnaeus's plant, must, from the description, be widely 

 different, and probably does not belong to the same natural 

 family.

 63] Carissa mitis, VaJil, symd. 3, p. 44 : a specimen of this, 

 so named by Kcenig, I have examined in the Banksian Col- 

 lection.
