P. lanala, R. Br. 1. c. aul Choisy, L c, from the same N. Australian localities, appears to 

 he a very densely silky-villous variety, the leaves much smaller, broad in R. Brown s spet-i- 

 menSj narrow in F, Mueller's, the flowers rather smaller, mostly solitary. 



P. quadrivahis, E. Br. 1. c. and Chois. 1. c. (the above-quoted specimens from Thirsty 

 Souad, R. Brown), appears to me to be another variety, nearly glabrous, with rather small 

 solitary flowers, connecting F. amhigua with P, pusilla. 



7. P. pusilla, B. Br, Prod. 488. This may be another small slemler 

 form of P. amhigua, glabrous or slightly pubescent. Stems almost tihform, 

 prostrate or twining. Leaves on slender petioles, from cordate-ovate obtuse 

 or retuse and under 1 in. long, to linear and then entire or hastate at the 

 base. Peduncles l-flowered, with minute bracts at a distance from the 

 flower. Sepals nearly equal, lanceolate, acuminate, about 3 lines long. Co- 

 rolla about twice as long, very open. Stigmatic branches usually 4.— tnois.
