pous tuber, the librous roots arising near the apex (incl. P. pedicel- 

 latüj P. mexicana , P. ovnta-peltatn , P. claytonioides , P. pintdana, 

 P. Gaiidichaudii j P. graciUima , P. hracteata, P. campylotropa) : 

 4) Rhisomatosae with a tuberous rhizome (incl. P. macrnnda , P. 

 mexicana, P. rupiceda, P. nionticola, P. cotyledon). The seven new 

 species are: P. cyclaminoides A. W. Hill (with an orbicular lamina, 

 which is leathery); P. verruculosa Dahlst. (with an ovate, strongly 

 verruculose berry); P. niinuta A. W. Hill (with an ovate-elliptical, mi- 

 nately punctate berry); P. falsa A. W. Hill (with a subcoriaceous lamina 

 and a globose berry, produced apically into a cylindrical appendage); 

 P. Gaudichaiidii A. W. Hill (with a more or less membranous lamina, 

 the veins conspicuously reticulate; berr}^ globose-ovate); P. hracteata 

 A. W. Hill (with conspicuous, orbicular bracts; stamens with fila- 

 ments); P. campylotropa A. W. Hill (with ovate-acuminate bracts; 

 anthers subsessile). 



The paper also includes a general discussion of the morphology 

 and geographical distribution of the species in question.
