22 Dr. Hancock on the Angustura Bark Tree. 



there already existed a Genus of that name, and although the 

 Angustura Bark Tree most obviously belonged to the Genus 

 Galipea of Aublet:* — Humboldt, and subsequently Humboldt 



* In the above opinion, formed in the year 1816, I am confirmed by the fol- 

 lowing extract from the Prodromus Systematis Naturalis Regni Veyetabilis of De 

 Candolle, (vol. I, p. 730,) a work which I have been enabled to consult only 

 since my recent return to England, and to which, after I had nearly completed 

 this paper from the numerous observations I had made 12 years ago, my attention 

 was directed by Mr. Yosy, Sec. Med. Bot. Soc, who having mentioned the subject 

 to Mr. David Don, the learned Librarian of the Linnaean Society, was by him 

 informed of the improved arrangement made by De Candolle.

I have to acknowledge my obligation for some of the hints above given, with 

 regard to nomenclature, to De Candolle's paper on the Cusparia- in the Mem. 

 Mus. 9, p. 148, and to the learned work of Messrs. Roemer and Schultz. 



It might be here remarked that trifoliata seems not to be a very appropriate 

 specific distinction, since there are no less than four species of Galipea already 

 known as three-lcavcd. Besides which, the threc-lcavtd Sciunis or Ratiitia of 

 Aublet, of which I possess very perfect specimens, appears also to be a true spe- 

 cies of this Genus. Aublet neglected to give a precise description of the fruit,
