A Grammatical Dictionary of Botanical Latin

Vepres (vepris, veper)(gen. sg. -is) (s.m.III), abl. sg. vepre; more usual in the plural: vepres, gen. pl. veprium, dat. & abl. pl. vepribus: a thorn-bush, briar- or brier-bush, bramble-bush; see bramble, briar, thicket; perhaps a synonym of sentis,-is (s.m.III), q.v.

- nascitur hac elegans, & rara planta in quadam valle Gargani Арuliae montis inter vepres, & senticosa loca (Mich.), this elegant and rare plant grows in a certain [i.e. unspecified] valley of Mount Gargano of Apulia (Italy) among bramble-bushes and thorn-thicket places.

NOTE: perhaps ‘vepres’ may refer more to thorn-trees. Thorn-trees are “any of various thorny or spiny trees, as Hawthorn” (WIII).

Thornbush: “any of various spiny or thorny shrubs or small trees.”

Thorn forest: “a tropical xerophytic savanna woodland commonly dominated by small thorny trees” (WIII).

Thorn (Eng.noun): “a woody plant bearing briers, prickles, spines or other sharp impeding process; a plant of the genus Crataegus, as Hawthorn, pear Haw; a growth or thicket of thorn” (WIII).
