Boraginaceae: Annual, biennial or perennial herbs, rarely shrublets or trees. Leaves alternate, exstipulate, simple, often with marked setose indumentum. Ultimate branches of inflorescences cymose, cymes scorpoid or circinnate (circinni), or inflorescence rarely thyrsoid. Calyx gamosepalous, 5 lobed (rarely 9 lobed or irregularly dentate), often accrescent after anthesis. Corolla 5 lobed, actinomorphic or rarely zygomorphic, usually with distinct tube and ± deeply lobed limb; throat often with 5 appendages or tufts or a zone of hairs, or smooth and glabrous. Stamens 5, epipetalous, alternating with corolla lobes. Ovary superior, 4-(rarely 2) locular; style gynobasic, more rarely terminal, usually undivided, stigma entire or 2(-4) lobed. Fruit usually of 4 nutlets, rarely fewer by abortion or fusion, or of 2 corky mericarps, or a drupe; nutlets borne on flat to pyramidal gynobase, attachment scar narrow to broad, without or with a sub basal ring or stalk, with erect to subhorizontally incurved beak or unbeaked, keeled or not, often differentiated into disc and margin; margin sometimes prolonged into a spreading or incurved wing, or spiny glochidiate; surface smooth or variously ornamented, glabrous, hairy or with glochidiate tubercles and/or spines.
