visions of the calyx. In the structure of the capsule and seeds 

 both genera entirely correspond. 



The Viviania mar'ifolia, of which Cavanilles appears to have, 

 seen but an imperfect specimen, collected by Don Luis Nee, 

 near Acapulco, comes very near to Mr Lindley''s Macrcea rosea, 

 but the calyx is exhibited, in the figure above mentioned, as 

 pentaphyllous, which, howevei', is most probably an error. 



I have nothing to add to the excellent description given by 

 Mr Lindley of the genus, in Brande's " Journal of Science," 

 vol. XXV. p. 104.

PALO DE VACA. No. C. p. 336. 

 Having lately had an opportunity of examining a nut of this 

 tree, collected in Caraccas by Mr Fanning, who has also brought 

 a considerable number of young plants of it to England, I am 

 now satisfied of its being really a species of Brosimum, as M. 

 Kunth has already suspected . The name of Brosimum Galac- 

 todendron may well be applied to the species. 



CICHORACE^. No. 12. p. 306. 

 In writing out the prefatory remarks to the memoir on the 

 above family, I have inadvertently fallen into an error in stat- 

 ing the anthers of Composite to be unilocular, they being really 

 bilocular, and each cell composed of two unequal valves, the 

 innermost being the narrowest. The characters of Troximon, 

 p. 309, are derived from T. glmiciis and cuspidatus of Pursh ; 

 and I rather think that T. dandelion of Gasrtner will prove to 

 be a species of Cynthiu, a genus sufficiently distinct from 

 Krigia.
