Obs. I. Planta jamaicensis a cl. Gkisebach huc laudata verisimiliter a 

 cl. W. Wright in Antillis minoribus collecta est (cf. Urb. Symb. YII p. 77), 

 dum in insula Trinidad Pr. guianense (Aubl.) March. crescit. 



Obs. II. Pr. guianense (Aubl.) March. (e Guiana) foliolis multo brevius 

 petiolulatis, inflorescentiis valde abbreviatis, floribus semper 4-meris, fructu 

 duplo breviore sine ulla dubitatione specifice diversum est. Hocce (a cl. 

 Engler determinatum) in duabus formis (an speciebus propriis?) adest, 

 altera foliolis supra laevibus (non prominulo -reticulatis), inflorescentiis bre- 

 vibus panniculatis laxifloris (Rieh. Scliomburgk n. 894), altera foliolis supra 

 densissime et elevatim reticulatis, inflorescentiis fasciculatis , alabastris elon- 

 gatis etc. (Cayenne s. coli., Jcnman n. 492G). Quae veram plantam Auble- 

 tianam praebeat, exemplaria originaria musei Britannici docebunt. 



Obs. III. Characteres a cl. Engler in hoc genere ex ovario et style 

 et antheris adhibiti iterum accurate investigandi et in floribus masculis sicut 

 in femineis comparandi sunt. 



Obs. IV. Postquam diagnosin antecedenteni scripsi, enumeratio Bur- 

 seracearuni in North Amer. Flora vol. 25 part 3 a cl. Rose exarata in lucem 

 prodiit, qui speciem caribaeam ei e Guadeloupe tantuni cognitam primus 

 publici juris fecit. Cur cl. auctor nomen genericiun Aubletianum junius 

 Icica praetulerit, mihi omnino incognitum est.
