Gardner's n. 10, from Rio Janeiro is S. lanceolata, St Hil.; 

 n. 922 from Pernambuco is very near to that species, and to 

 S. mollis, Humb. et Kunth, but appears different from either; 

 it is also in Salzmann's Bahia collection; n. 1456 of Gard- 

 ner's Ceara collection is very near to S. divaricata, Mart., if 

 not the same species. 



Amongst the Sierra Leone plants collected by Mr G. Don 

 for the Horticultural Society, are two PolygalaceoB, allied to 

 Securidaca, which tend much to elucidate the true structure 

 of the flower in this order, as noticed by R. Brown, wlio 

 alludes to one or both of them as an undescribed genus in 

 his Appendix to Flinders' Voyage, {Verm. Schr. i. 28.) 

 These plants have since been published by G. Don, (Gen. 

 Syst. i. 370), under the name of Carpolohia, a genus in which 

 he has comprised a leguminous plant, {Delaria, Desv. ; Car- 

 polohia dubia, G. Don), and a fourth species unknown to me, 

 perhaps a Securidaca. As the generic character drawn up 

 partly from one, partly from another, of these heterogeneous 

 plants, is wholly unintelligible, and not applicable to anyone 

 species, I take this opportunity of subjoining an anjended 

 character derived from the two which I have examined, and 

 which I believe to be G. Don's C. lutea and C. alba.
