cies which are not determined. The P. lanceolata, L., on the 

 banks of rivers ; the P. hispidula, Ruiz and Pavon, in sandy spots 

 upon the plains and highland. The P. Patagonica. Jacq., on the 

 mountains of Leona. The L. truncata and iumida, Chamiss, are 

 met with in banancos — the dry beds of mountain torrents, and in the 

 pastures on the highland. 



Poa annua, P. pratensis and P. pilosa. L. Grasses frequent in 

 cultivated situations, in fields, and near drains. The last is very com- 

 mon on farms, and does not differ from the European species, all the 

 characters of which it possesses, except that it is larger. They have 

 all been introduced. 



Polianthes tuberosa. L. J\largarita. Cultivated in gardens. 

 The variety with double flowers is less known. The odor of the 

 flowers is pleasant, though rather strong. 



Polygala Thesioides. W. A shrub met with in the mountains, 

 vulgarly called Quelenquelen. The root is used in decoction in 

 many diseases which are called internal. The P. Gnidioides, W. 

 does not differ from the preceding, except in its herbaceous stalk. 

 It is found in fields and along the skirts of woods in the highland. 



Polygonum aviculare. L. Sanguinaria. It is found in all dry, 

 stony situations along roads. The variety with straight stalks grows 

 in humid meadows and about marshes. Its decoction is prescribed 

 in certain female complaints. The P. Persicaria and lapathifoK- 

 um, L., duraznillo, frequent in drains and pools. They are employ- 

 ed for the same purposes, and if we may believe what we hear res- 

 pecting them, possess great virtues. The P. orientale, L., should 

 be cultivated for the beauty of its flowers ; and the P. Fagopyrum, 

 L., for hs farinaceous grain which might form a substitute for wheat. 



Polypodium. L. Ferns which grow in woods, on the mountains, 

 and among stones. The doradilla, a species of this genus not de- 

 termined, is considered a great remedy in certain diseases. The 

 yerha del lagarto which I take to be the Polypodium radice squamosa^ 

 FeuilL, appears to be a new species which I will name, P. Feuillei, 

 and another which is called palmilla. This approaches the P. resi- 

 niferum, Desv : I believe it however to be different. The last two 

 were found and communicated to me by Don Vicente Bustillos. 



Polypogon. Desv. The name rabo de zorro, is also given to two 

 species of this genus, one of which is the P. maritimus, W. ; the 

 other does not agree with any yet described. It is found in drains 

 and in fields on the plain.
