 FT A Lo P. Quartiniana Dillon, Ihas maintaining Ihree species insLead of

 looked these Gambia n spécimens of P. arenaria, as Ibey are not cited in 

 the distribution of Ihe species on p. 338. Lesler's example in Herb. Kew. 

 is 4 dem. long, and is a complète spécimen showing also the fibres of the 

 annual root. The leaves, which are so characteristically variable in the 

 species, arein tliis example linear-elliptical obtuse.
