Psammogeton setifolium, Boissier. 



Persia and Afghanistan. An annual herb, the fruit of which is 

 locally used as an aromatic condiment and as a medicine [Brigade- 

 Surgeon J. Aitchison]. 



Pseudophoenix Sargenti, H. Wendland. 



Islets of Florida. A palm seldom above 25 feet high, therefore 

 easily placed. Comparatively hardy. 



Psidium acutangulum, De Candolle. (P. acidum, Martius. ) 



Higher regions on the Amazon-River. A tree, at length 30 feet 

 high ; its guava-fruit pale-yellow and of apple-size. 



Psidium Araca, Raddi.* 



From the West-Indies and G-uiana to Peru and Southern Brazil,, 

 where it is found in dry high-lying places. This is one of the edible 

 guavas, already recorded by Piso and Marcgrav. The greenish- 

 yellow berry is of exquisite taste. 



Psidium arboreum, Vellozo. 



Brazil, province of Rio de Janeiro. The guava-fruit of this plant 

 measures about one inch, and is of excellent flavour. 



Psidium Cattleyanum, Sabine.* 



The Purple Gruava. Brazil and Uruguay. One of the hardiest 

 of the guava-bushes, attaining finally a height of 20 feet. The 

 purple berries are seldom above an inch long, but, as well known, 

 of delicious flavor and taste, resembling thus far strawberries. P. 

 buxifolium (Nuttall) of Florida seems nearly related to this species. 



*Psidium chrysophyllum, F. v. Mueller. (Abbevillea chrysophylla, Berg.) 

 The Guabiroba do Mato of South-Brazil. This tree attains a 

 height of about 30 feet. The fruit is generally nor larger than a 

 cherry. Perhaps other species of the section Abbevillea would be 

 hardy and worthy of cultivation. 



Psidium cinereum, Martius. 



Brazil, provinces Minas Geraes and Sao PauJo. Also yielding an 

 edible fruit. 



Psidium CUneatum, Cambessedes. 



Brazil, province Minas Geraes. Fruit greenish, of the size of a 

 Mirabelle-plum.
