Ehretia pranomiana sp. nov. (Boraginales: Ehretiaceae), a new scrambler from Thailand
<i>Ehretia pranomiana</i> sp. nov. is illustrated and described from northern and south-western Thailand. The new species is similar to <i>E. macrophylla</i> and <i>E. acuminata</i> by having elliptic leaves with a serrate margin, but can be distinguished by its scrambling shrubs, leaf blades with densely hispid, corymbose inflorescence with 4–10 flowers, the corolla with erect lobes and the calyx longer than fruit at maturity. An updated species identification key is provided.
