 See 2^g. 781. 



rubrum Vahl. Andes of S. Chile and Argent, to Fueg. and Falkl.; Tristan da C. 



Convolvulaceae. 



DicJiojidra Forst. 5 trop.-subtrop. Amer., i X. Zeal., and the following. 



repens Forst. Widely spread over both hemispheres, north to N. Amer. and 

 China, south to S. Chile and X. Zeal. 

 Calystegia R. Br. 10-20; temp.-subtrop. in all parts of the world. 



tuguriorum R. Br. S. Chile (Hantelmanni Phil.) and X. Zeal. 



Boraginaceae. 



Selkirkia Berteroi (Colla) Hemsl. According to JoiINSTOX {14S) very near Hackelia 

 Opiz, a genus centering in western X. Amer., with outposts in S. Amer. and 

 Euras.; H. rezjoluta (Ruiz et Pav.) Johnst. Peru to Boliv. and Argent. 



Verbenaceae.

Labiatae. 



Cuminia Colla. 2. An isolated genus, referred to Prasioideae by EPLING (90), a 

 palaeotropical group best developed in Hawaii, but whereas Cuminia has the drupe 

 of this tribe, it has the corolla o'i Stachyoideae-MeJitJiinae, where BRIQUET placed 

 it; Burger's statement that the flowers are "LippenbliJten" (.//. 23) is erroneous. 

 fernandezia Colla and eriantha lienth. Perhaps united by intermediate forms. 



Solanaceae. 



Solantim L. Probably over 1000; in all parts of the world, richly represented in 

 trop. Amer, many in Chile. 



fernandezianum Phil. Related to S. tuberosum L. coll.

 Nicotiana L. 60; 45 Amer., Calif.-Mex., And. S. Amer. (Ecuad.-Peru-Chile, Braz.- 

 Argent.-Patag.), 15 Austral, (i X. Caled., etc.). 



cordifolia Phil. Belongs to the Rustica group, confined to trop. Amer. and 

 Australas., and related to N. Raimojidii Macbr. (Andes of S. Peru), solanifolia 

 Walp. (X. and Centr. Chile) and paiiiculata L. (Peru, X. Chile). Dr. GOODSPEED 

 expressed his opinion (in litt.) that the Rustica complex originated in the region 

 now occupied by western Bolivia and Peru and extended to the "Juan Fernandez 

 land", becoming isolated during the final uplift of the Andes or possibly even earlier.
