Psamma arenaria, Roemer and Schultes. (P. littoralisj 

 Beauvois, Calamagrostis arenaria, Koth.) 

 The Moram or Marrem or Bent Grass. Sand-coasts of 

 Europe, North Africa and Middle North America. One of 

 the most important of reedy grasses, with long creeping 

 roots, for binding and moving drift-sands on the sea-shore, for 

 the consolidation of which in Europe chiefly this tall grass 

 and Elymus arenarius are employed. Psamma Baltica (R. 

 and S.) from the Baltic and North Sea, serves the same pur- 

 pose. Both can also be used in the manner of Sparta for 

 paper material, for tying and for mats. Like Elymus 

 arenarius it is not touched by pastoral animals. It collects 

 the sand-heaps at the tops of ridges, while the Elymus 

 fastens their sides. 



Psidium acidum, Martins. 



Higher regions on the Amazon River. A tree thiiiiy feet 

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



Psidium Araca, Raddi. 



From West India and Guiana to Peru and Southern Brazil, 

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

 the edible Guavas, recorded already by Piso and Marcgiav. 

 The greenish-yellow berry is of exquisite taste. 



Psidium arboreum, Yellozo. 



Brazil; province Rio de Janeii'o. This Guava-fruit measures 

 about one inch, and is of excellent flavoui'. 



Psidium Cattleyanum, Sabine.* 



The Purple Guava. Brazil and Uruguay. One of the 

 hardiest of the Guava-bushes, attaining finally a height of 

 twenty feet. The purple berries are seldom above an inch 

 long, but of delicious flavour and taste, resembling thus far 

 strawberries. P. buxifolium (Nutt.) of Florida, seems nearly 

 related to this species. 



Psidium chrysophyllum, F. v. Mueller. {Ahhevillea 

 chrysopiiylla, Berg.) 

 The Guabiroba do mato of South Brazil. This tree attains 

 also a height of about thirty feet. The fruit generally not 

 larger than a cherry. Perhaps other species of the section 

 Abbevillea would be hardy here and worthy of cultivation. 



Psidium cinereum, Martins. 



Brazil; provinces Minas Geraes and Sao Paulo. Also yield- 

 ing an edible fruit. 



Psidium cor datum, Sims. 



The Spice Guava. West India. This one attains the height 

 of a tree. Its fruit edible.
