Naturalisation in Extra-Tropical Countries. 433 



Psidium grandifolium, Martius. 



Brazil, provinces Rio Grande do Sul, Parana, Sao Paulo, Minas 

 Geraes, where the climate is similar to Southern Queensland. A 

 shrub of rather dwarf growth. The berries edible, size of a 

 walnut. 



Psidium Guayava, Linne.* (P. pomiferum, Linne; P. pyriferum, Linne.) 

 The larger Yellow Guava. From the West-Indies and Mexico to 

 South-Brazil. This handsome evergreen and useful bush should 

 engage universal attention anywhere in warm lowlands, for the 

 sake of its aromatic wholesome berries, which will attain the size 

 of a hen's egg, and can be converted into a delicious jelly. The 

 pulp is generally cream-coloured or reddish, but varies in the many 

 varieties, which have arisen in culture, some of them bearing 

 all the year round. Propagation is easy from suckers, cuttings or 

 seeds. This big shrub is easily held under control in extra-tropic 

 countries, but in the warmest and moistest tropical regions it may 

 become irrepressible, as it spreads readily from suckers, and gets 

 disseminated by birds and cattle easily [R. L. Holmes]. Many 

 other berry-bearing Myrtacese of the genera Psidium, Myrtus, 

 Myrcia, Marliera, Calyptranthes and Eugenia furnish edible fruits 

 in Brazil and other tropical countries ; but we are not aware of 

 their degrees of hardiness. Berg enumerates as esculent more than 

 half a hundred from Brazil alone, of which the species of Caropo- 

 manesia may safely be transferred to Psidium. 



Psidium incanescens, Martius. 



Brazil, from Minas Geraes to Rio Grande do Sul. This guava- 

 bush attains a height of 8 feet. Berry edible. 



Psidium lineatifolium, Persoon. 



Mountains of Brazil. Berry about 1 inch in diameter. 



Psidium malifolium, F. v. Mueller. (Campomanesia malifolia, Berg.) 

 Uruguay. Berry about 1 inch in diameter. 



Psidium montanum, Swartz. (P. cordatum, Sims.) 



The Spice-Guava. West-Indies. This attains the height of a 

 tree. Its fruit is edible. Probably hardy in sub-tropic regions. 



Psidium polycarpon, Al. Anderson.* 



From Guiana to Brazil, also in Trinidad. A comparatively small 

 shrub, bearing prolifically and almost continuously its yellow berries, 

 which are of the size of a large cherry and of exquisite taste. 



Psidium rufum, Martius. 



Brazil, in the province of Minas Geraes, on sub-alpine heights. 

 This guava-bush gains finally a height of 10 feet, and is probably 

 the hardiest of all the species producing palatable fruit.
