the warm aud temperate regions of the earth, and in many places 

 they are so thoroughly established as to be commonly regarded 

 as indigenous. 





Loasace^. 





t>o. Loasa PiNtfATiFiDA, Gill, ex Am. in Edinb. Joum. JVat. Sf 

 Ueog.Sc. iii. p. 273 (1831) = L. filicifolia, Poepp. Fragm. 23. 



-this is a mere fragment, but it agrees well with the original 

 specimen collected by Gillies. With regard to this as well as 

 several other South-American Loasacea? of which mature fruit is 

 not round in European herbaria, I regard the generic position as 

 quite uncertain. 









CUCUKBITACEJ). 





















3 and 8. "Wilbkaxdia yillosa, Cogn. "Creeping plants; 

 dark green foliage, small yellow blossom ; found on gravel and 

 Pebble banks in vicinity of sea-coast."— W. Andrews. This 

 species appears to have a wider range than has previously been 

 supposed. All the specimens which I have seen come from the 

 territory of Uruguay, and those quoted by Cogniaux"S. Brazil " 

 ^e probably from the same region. Dr. Lorentz collected it 

 j* the province of Cordova ; but it now appears that it extends 

 «* to the south. 







Cactace^!. 



!• Ckreus leucanthus, Pfeiff. Enum. diagn. Cact. p. 71 

 Echinocactus leucauthus, Gill. = Echinonyctanthus leucanthus, 



I^tnaire ? 



"Blossom large, white, with yellow eye, of a cactus. This 

 ^ows up in a long round spike about 4 or 5 inches in circum- 

 ference to a height of 2 or 3 feet ; from the top, or near it, springs 

 the flower-stem."— W. Andrews. Professor Oliver is disposed to 

 * f « the specimen to the same species which was collected 

 near Mendoza by Gillies. It appears to me somewhat uncertain. 



2 - Opxjniia gbata, Phil. ? " Blossoms yellow of a cactus, 

 grows in large ovals about 6 inches long by 8 wide, the flowers 

 ■Nng direct therefrom without any stem. Both this species 

 J* d the last produce a purplish-red fruit of a sweetish taste. 

 «■«*» the appearance is that of a fig ; the fruit is most refresh*
