MYRTACEAE. 253 
Psiprum. Guava. 
(Family Myrtaceae). 
Tender trees: evergreen. Twigs 
moderate, terete, or 4-ribbed or 
even winged below the nodes: pith 
moderate, compressed, 4- sided, 
spongy, brown. Buds solitary, 
sometimes developing promptly, 
naked. Leaf-scars opposite, broadly 
crescent-shaped, raised, black-cili- 
ate at top: bundle-trace 1, crescent- 
shaped: stipule-scars lacking. 
Leaves simple, entire, pellucid- 
punctate, with looping veins. 
Guavas scarcely possess any de- 
corative value, but they are grown 
in most tropical gardens for their 
small rather peculiarly flavored 
seedy fruits, — most favorably 
known in the West Indian guava 
jelly which is justly esteemed one 
of the best of confections. 
Twigs angled, hairy. (Guava). (1). P. GQuayava. 
Twigs terete, glabrous. (Strawberry guava). P.Cattleyanum.
