Myrteola Berg. 12, Colomb.-Chile. 



mimmularia (Poir.) Berg. Chile, Cord. Linares to Fueg., F'alkl. 

 Nothomyrcia Kausel. A monotypical genus, related to Chilean genera. 



fernandeziana (Hook, et Arn.) Kausel. 

 Myrceugenia Berg. About 40; trop. Andes, S. Braz. (many sp.) and about 20 in 

 Chile, south to Chiloe. 



Schulzei Johow. Related to M. planipes (Hook, et Arn.) Berg (S. Chile). 



Gunneraceae. 



Gunnera L. About 30 sp. Subgen. Pangue, 16 sp. Costa Rica, Colomb.-S. Chile, 

 Magell., Braz.; Hawaii 2 sp., but some more, of doubtful taxonomic status, have 

 been described. Other subgenera in the Andes of Colomb. to Chile, south to 

 Fueg. and F'alkl.; Urug.; S. and Centr. Afr.; Malays.-Philipp. Is.; N. Zeal., Tasm. 



peltata Phil, and Masafuerae Skottsb. related to Andean sp. 



bracteata Steud. Seems to come closer to the Hawaiian G. kaMaie7isis Rock 

 than to S. Amer. species. 



Halorrhagidaceae. 



Halorrhagis Forst. About 80, the great majority Austral.-N. Zeal., single sp. 

 scattered north to Indonesia, Philipp. Is., China and Japan, and east to Rapa 

 and J. Fern. 



asperritna Skottsb., masatierrana Skottsb. and masafuerana Skottsb. belong 

 to Subsect. Cercodia and are closely related to H. erecia (Murr.) Schindl. (N. Zeal.) 

 and other Austral, and N. Zeal. sp. All J. Fern, forms were formerly incorrectly 

 identified with erecia. 



Umbelliferae. 



Cejttella L. 29; 19 Afr., Madag., i China, 2 Austral., 5 trop. Amer. and the 

 widely dispersed C. asiatica (L.) Urb. 



triflora (Ruiz et Pav.) Nannfeldt. Centr. and S. Chile, formerly included under 

 asiatica. Introduced .r* 



Eryngium L. About 230, in all parts of the world, but with two centres: W. Eur.— 

 Medit. and trop.-subtrop. Amer. Poorly represented in N. Amer. and Australas. 



bupleuroides Hook, et Arn., inaccessum Skottsb. and sarcophyllum Hook, 

 et Arn. form a special sect. Fruticosa, but differ mainly in being arborescent from 

 the species occurring on the mainland. 

 Apium L. About 30; in all parts of the world. 



fernandezianutn Johow. A well-marked species, probably not nearly related 

 to the Chilean species, but showing some affinity to A. prosiratiini Labill. (Austral.) 

 or australe Thouars (Tristan da C.) 



Ericaceae. 



Pernettya Gaud. About 12, 6 or 7 Mex. and Centr. Amer. and along the Andes 

 to Fueg. and Falkl.; i Galapag. Is., 2 N. Zeal., 2 Tasm.
