Of all the fruit-bearing trees of tropical countries, the 
Guava most readily submits to the arts of the gardener. 
There are four eatable species in our hot-houses, namely, 
P. pyriferum, pomiferum, polycarpum, and Cattleianum ; all 
of which repay the care of the cultivator with plentiful 
crops of fruit. 
Like the Apple and Pear of Northern nations, the 
Guava produces many varieties, differing in the form and 
quality of their fruit. That now figured is distinct from 
any previously published, being remarkable for the small 
size, round figure, and smooth surface of its fruit, which 
also possesses an unusual proportion of acid. Most com- 
monly the fruit is larger, more oblong, and has an uneven 
coat, like that of an orange. 
This species, however, is not that which we should 
recommend for cultivation; the best is the purple Guava,
