Genus CHRYSOBALANUS. 



This tropical Genus near to PRUNUS extend^ 

 to Florida and we have several sp. only one 

 was known, I shall describe 4. 



539. CHRYSOB. OBLONGIFOLIUS MX. Branch- 

 lets redish rugose, leaves suhsessile 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, ealix campannlate 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 Chr. 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
