Art. VI. The Guava {Vs'idiuni Catileyknum) ; its Cultiva- 

 tion and Management. By the Editor. 



Some years since, after reading an account of Cattley's 

 Guava, (Psidium Cattleyd^w??,,) in the Transactions of ihe 

 London HorticuUural Society, accompanied with a beauti-

 its appearance that we made great exertions to procure a 

 plant. Fortunate, as we thought we were, in finding one, 

 we cultivated it carefully for a long time, and began to despair

 and, on our return home, we had the pleasure of raising six 

 or eight plants, which grew finely, and produced some fruit 

 in the fall of 1846, though only about fifteen inches high. 

 In 1847, they bore again ; and the past autumn so abun-

 of the fruit. 



The Psidium Cattleyd/zww is not only one of the richest 

 dessert fruits, but is one of the most ornamental plants in the 

 greenhouse. The growth is vigorous, regular, and upright, 

 with slightly pendulous branches, and witli large, deep green, 

 glossy leaves, nearly as handsome as the camellia. The an-
