Essential Character. — Calyx superior, 5-toothed; the odd segment posterior. 
Petals 5, unguiculate, inserted in the throat of the calyx ; the odd one anterior. Stamens 
indefinite, inserted in a ring in the throat of the calyx. Disk thin, clothing the sides of 
the tube of the calyx. Ovaries from 1 to 5, adhering more or less to the sides of the calyx 
and each other ; ovules usually 2, collateral, ascending, very rarely solitary ; styles from 1 
to 5; stigmas simple. Fruit a pome, 1- to 5 -celled, seldom spuriously 10-celled; the 
endocarp either cartilaginous, spongy, or bony. Seeds ascending, solitary. Albumen 
none ; embryo erect, with flat cotyledons, or convolute ones in Chamaemeles, and a short 
conical radicle. — Trees or shrubs. Leaves alternate, stipulate, simple, or compound. Flowers 
in terminal cymes, white or pink. 
Anomalies. In Amelanchier the simple ovaries are spuriously 2-celled. In Crataegus 
the ovaries are very rarely solitary. 
Affinities. Closely allied to Rosaceae proper, from which they differ in 
the adhesion of the ovaries with the sides of the calyx, and more or less with 
each other. The fruit is always a pome ; that is, it is made up of a fleshy 
calyx adhering to fleshy or bony ovaries, containing a definite number of seeds. 
Pomeae are peculiarly distinguished by their ovules being in pairs, and side 
by side ; while Rosacese, when they have 2 or more ascending ovules, always 
have them placed one above the other. Cultivated plants of this sub- order are 
very apt to produce monstrous flowers, which depart sometimes in a most 
remarkable degree from their normal state. No order can be more instruc- 
tively studied with a view to morphological inquiries ; particularly the common 
Pear when in blossom. A remarkable permanent monster of this kind, with
