nating with and inserted below perianth-leaves ; filaments short free, 
or nearly absent; anthers dorsifixed 2-celled introrse 2-rimose. Disk 
glandular, of variable form, inserted in throat of receptacle. Germen 
free, inserted in and included by bottom of receptacle ; style simple, 
passing out through narrow mouth of receptacle, longitudinally 
furrowed ; apex straight curved or circinate, laterally stigmatiferous; 
ovule 1, ascending anatropous ; micropyle inferior. Fruit enveloped in 
persistent accrescent drupaceous receptacle; pericarp dry thin inde- 
hiscent ; seed erect ; embryo fleshy ; albumen small or 0; radicle short 
inferior.—Trees or shrubs, covered in almost every part with scurfy 
or stellate hairs; twigs often spinescent; leaves alternate petiolate 
entire exstipulate ; flowers axillary pedicellate, solitary or in few- 
flowered cymes, more rarely in short axillary leafy racemes (North 
America, southern Europe, temperate and southern Asia). See p. 481.

A alternate with perianth-leaves; filaments very short; anthers in- 
trorse 2-rimose. Glands 8, in male alternate with stamens, in female

shrubs, scurfy sometimes spinescent; leaves opposite; flowers pre-
