* Psidium pomiferum, Linn. ; DC. Prod. iii. 234, the Guava, a native 
of tropical America, is subspontaneous in many places in Mauritius, 
Rodriguez and the Seychelles. It is a much-branched shrub, 10-15 
feet high, with angular puberulent branchlets, nearly sessile oblong 
coriaceous obtuse strongly penninerved leaves 3-6 in. long finely downy 
below, solitary stalked flowers in the axils of the leaves, small globose 
calyx-tube constricted at the neck, ovoid entire calyx-limb which 
splits when the flower expands into four unequal lobes, expanded 
corolla an inch broad, many-celled ovary, filiform style, entire stigma, 
and large round fleshy yellow or reddish edible fruit. P. pyriferum , 
Linn. ; DC. loc. cit., is a variety with fruit shaped like a pear.

* P. Cattleyanum, Sabine, Bot. Reg. t. 622. (P. indicum, Bojer , Hort. 
Maur, 139; P. variabile, Berg . ; P. obovatum and coriaceum, Mart.), a 
native of Brazil, was introduced into Mauritius about 1830, and is now 
widely spread and subspontaneous both there and in the Seychelles and 
Rodriguez. It is readily distinguished by its distinctly petioled obovate- 
leaves with a cuneate base, which have not the strong erecfco-patent 
parallel ribs of those of the other species. The peduncles are much 
shorter, and the corolla smaller. The fruit is globose or ovoid, red or 
yellow, 1-2 in. thick, with a more acid taste than that of the common 
Guava. Goyavier de China .
