Obs. 111. Hooker 1. e. dixit: ,,The seeds were received by Charles 

 HoRSFALL Esq. eitlier froiu Africa er from the East Indies", sed nullibi haec 

 species spontanea collecta est, nisi in Portorico, q\iod affinitate arcta cum

 ut in Omnibus descriptionibus legitur, sed etiani 7 procreat, quod specimina 

 Dussiana (sicut spontanea Sintenisiana) demonstrant.
