^ . S. Native about the Havannah, in Cuba, where we have 

 seen it growing in plenty, at very little distance from the town. 

 B.C. coll. 1. t. 7. It is very nearly allied to the preceding 

 species, but differs in the leaves being broader, cymes shorter, 

 and in the connectives of the anthers being hardly evident. 

 Havanna Chaetogastra. Shrub 1 to 2 feet.

 letely serrulated, strigose on both surfaces and ciliated on the

 pid ; leaves petiolate, oval, attenuated at the base, and acumin- 

 ated at the apex, 5-nerved, hardly serrulated, (lateral nerves 

 confluent at the base,) villous above, hispid on the nerves be- 

 neath, bift pubescent between the nerves ; panicles lateral and 

 terminal, disposed in a thyrse ; calyx ovate, villous, with subu- 

 late lobes ; connectives of anthers very short, furnished with 2 very 

 short tubercles at the base of each. TJ. . S. Native of Brazil. 

 Like C. lanceolata and C. Havanensis, and probably all three 

 constitute but one species. Flowers white.

 ceeding the calycine lobes. 0. S. Native of Guiana, in 

 marshes. Melastoma villosa, Aubl. guian. 1. p. 168. Rhexia

9 C. LYCHNITOIDES (D. C. 1. c.) plant herbaceous, erect ; stem 

 almost simple, densely beset with spreading hairs; leaves ses- 

 sile, oval, acute, clothed with adpressed silky villi, 7-nerved, 

 quite entire ; thyrse elongated ; flowers bracteate, crowded 

 on the peduncles ; calyx villous, with an ovate tube, nearly 

 twice the length of the lobes, which are lanceolate and acumin- 

 ated. If.? S. Native of Brazil, in the province of Minas 

 Geraes, on sandstone rocks. Rhexia lychnitoides, Schrank et 

 Mart. mss. Very like C. hypericoides, but differs in the calyxes 

 being twice the size, and in the flowers being more crowded. 

 Stamens unknown. Capsule 5-celled. Seeds small, cochleate, 

 smooth. 



Lychnitis-like Chaetogastra. PL 1 to 3 feet. 



10 C. STACHYOIDES (D. C. 1. c.) plant herbaceous, erect; 

 branches tetragonal, hairy ; leaves on short petioles, oblong, 

 obtuse at the base, acute at the apex, quite entire, 5-nerved, 

 clothed with adpressed villi ; flowers crowded into verticillate 

 heads in the axils of the leaves ; calyx 4-5-cleft : appendages 

 hair-formed, hardly distinct. Q. S. Native of Brazil. Rhexia 

 stachyoides, Bonpl. rhex. t. 43. Flowers rose-coloured. Five 

 of the stamens are almost without auricles at the base, and the 

 other 5 are furnished with a long connective each which ends in 

 2 bristles. There is a variety of this species, according to Bon- 

 pland, with 4-5-cleft octandrous or decandrous flowers.
