Leaves \ 1 in. long by in. wide. Calyx \ in. in diameter. Cfr. Parana. According 

 to Prof. Schimper, linger has comprised several different plants under this species, and 

 Ettingshausen in Sitzungsber. Math. Naturw. Akad. Wissensch. xxxvin. p. 492 (1858), 

 has shewn that the leaf which Unger described and figured for this species in Foss. Fl. v. 

 Sotzka, p, 172. t. 43. f. 15 (1851), is a leaflet of Cassia phaseolites, while he thinks that 

 Unger's fig. 16 may be a calyx of Celastrus.
