Genus CHRYSOBALANUS. 



This tropical Genus near to Prunus extends 

 to Florida and we have several sp. only one 

 was known, I shall describe 4. 



539. Chrysob. oblongifolius Mx. Branch- 

 lets redish rugose, leaves subsessile oblong or 

 subcuneate undulate, acute at both ends, lucid 

 reticulate quite smooth, flowers terminal pani- 

 culate, dichotome and trichotome, calix white 

 tomentose — in Florida, leaves 3 inches long, 

 yellowish minutely reticulate on both sides, 

 flowers small white, calix campanulate acute, 

 stamens smooth. Not less than 3 sp. appear to 

 have been blended by our Authors with this. 



540. Chrysobalanus retusa Raf. Branch- 

 es dark purple leaves subsessile entire, oblong 

 base acute, end obtuse retuse emarginate, re- 

 ticulate and quite smooth on both sides, above 

 coppery lucid, beneath pale yellowish less lucid 

 — found by Nuttal in Georgia and Alabama, 

 not named but Genus ascertained (Collins herb.) 

 It differs from Clir. oblongifolius by the re- 

 tuse leaves of a metalic color above, 3 to 4 

 inches long, over one broad, but 2 other sp. 

 have evidently been blended by Michaux and 

 Nuttal. 



541. Chrysobalanus incanus Raf. Var. of 

 oblongif. Mx. leaves oblong oboval, white and 

 wooly beneath — Florida. This must certainly 

 be distinct from the 2 above, having no speci- 

 men I cannot describe it better. 



542. Chrysobalanus (Spondolobus) pruni- 

 FOLius Raf. Branches smooth, leaves petio- 

 late ovate serrulate acute at both ends, base bi- 

 glandular, both sides smooth not reticulate,- 

 flowers racemose, raceme pauciflore, drupes 

 oblong — from Florida, in the Herbarium of
