MK. JOHN BALL ON THE 



plant appears to be not uncommon in some parts of Argentaria, 



wide 



Central Patagonia to Uruguay, and on the west coast extends 

 somewhat north of the tropic of Capricorn. 





25. Hoffmannseggia falcabia, Cav. "Small plant; height 

 4 to 6 inches, grows on clay soil in valleys of streams, though often 

 at a considerable distance from water ; flowers a dark orange, 

 mottled with deep brown spots." — W. Andrews. This is a small 

 form of a species which extends to the northern Argentine States 

 and also to the Chilian coast, generally growing to about 1 foot 

 in height. 











Hoffmannseggia 



tbifoliata, Cav. " Plant with small 

 dark yellow blossoms, mottled in throat with spots of very dark 

 purple growing in a spike ; generally in neighbourhood of sea- 



coast or river/ ' — W. 



This species, rare in herbaria, is 

 one of the few that appear to be peculiar to Patagonia. It was 

 originally described by Cavanilles from specimens collected at 



Puerto Deseado. 













29. Cassia aphtlla, Cav. " Shrub leafless and low growing, 

 height about 10 inches ; with yellow (dark gold) bell-like blossoms; 

 always found on high table-lauds in dry sandy soil."— W. Andrews. 

 This is apparently confined to the east side of the continent, 

 ranging from Northern (or Central ?) Patagonia to the Northern 

 States of the Argentine Confederation. 



















43. Pbosopis stbombulifeba, Benth. in Hook. Journ. Bot. iv. 

 p. 352. " Dwarf shrub ; height varying from 4 to 10 inches ; 

 root a very long straight tap descending perpendicularly. It 18 

 found throughout the plains of the Eio Negro valley, generally 

 in clay ground. Blossom a reddish yellow; fruit-pods of a 

 bright yellow in closely twisted spirals, four or five growing 

 together on a single stem. A decoction of these has a sweet, 

 bitterish, and aromatic flavour, and is used both by natives an 



Indians as a sovereign specific for dysentery, diarrhoea, &c. 



I am inclined to believe

the Southern Andes from Catamarca to Northern Patagonia, but 



not approaching the Atlantic coast. There is n specimen
