Morphology General Habit
Perennial (rarely annual) herbs, subshrubs or shrubs, usually non-aromatic (a few species reported to be aromatic)
Morphology Leaves
Leaves opposite, petiolate, entire, toothed or rarely pinnatifid
Morphology Reproductive morphology Inflorescences
Inflorescence of decussately or helically arranged flowers in axillary or terminal, often secund racemes or solitary in axils of foliage leaves
Morphology Reproductive morphology Inflorescences Bracts
Bracts present, reduced or not
Morphology Reproductive morphology Inflorescences Bracteoles
Bracteoles present or absent
Morphology Reproductive morphology Flowers Calyx
Calyx 2-lipped, accrescent, lips entire, rounded, becoming appressed at maturity, enclosing nutlets until posterior lip detaches to release them (or rarely the calyx indehiscent, inflated), posterior lip usually folded to produce a scutellum
Morphology Reproductive morphology Flowers Corolla
Corolla white, pink, blue, yellow or red, zygomorphic, tube straight or curved, often basally geniculate, usually 2-lipped, 4-lobed (3/1), with galeate posterior lip and unlobed anterior lip (less often weakly zygomorphic with 4 subequal, ± spreading lobe
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens usually included, thecae parallel to divergent, anther slit usually ciliate, anterior anthers dimidiate due to abortion of outer theca
Morphology Reproductive morphology Flowers Pollen
Pollen suprareticulate or rarely psilate
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary-lobes separate both above and below the style attachment (1/3 - 2/3 way to base of ovary) or rarely the style gynobasic
Morphology Reproductive morphology Flowers Disc
Disc well developed, often with anterior side swollen at the base of a peg-like gynophore
Morphology Reproductive morphology Fruits
Nutlets dry, usually ellipsoid to obovoid or subglobose, pubescent or glabrous, variously sculptured (often tuberculate), attachment-scar lateral or rarely basal
Morphology Reproductive morphology Seeds Endosperm
Endosperm absent
Morphology Reproductive morphology Seeds Embryo
Embryo usually bent with an incumbent radicle, more rarely bent at right angles or slightly curved.
Note
2n = 12-88 (most frequently 20, 22, 24, 32, 34).  About 360 species Paton (1990) distinguished subgenus Scutellaria, with one-sided inflorescences in which flowers are subtended by leaves or leaf-like bracts, from subgenus Apeltanthus Juz, with four-sided
Distribution
Subcosmopolitan but poorly represented in moist tropical lowlands.  Cassida Ség., Pl. Veron. 3: 130 (1754).

Morphology Reproductive morphology Flowers Corolla
Corolla 2-lipped; tube ± S-curved; upper lip ± hooded; lateral lobes more closely jointed to upper lip than to the lower; lower lip entire, rounded, ± flat
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 4, included in the upper lip of the corolla; anthers of the posterior pair 2-thecous, ciliate, with separate thecae; anthers of the anterior pair with lower theca only

Style 2-lobed at the apex with the lower lobe longer; ovary born on a short gynophore
Morphology Reproductive morphology Fruits
Nutlets papillate or smooth, with a small ventral scar at the base.
Distribution
Some 470 species in most parts of the world.

Morphology General Habit
Perennial, erect or suffruticose herbs to 1.5 m tall
Morphology Leaves
Leaves opposite
Morphology Reproductive morphology Flowers
Flowers hermaphrodite, single, opposite and secund in the axils of small, entire leaf-like bracts, forming a condensed or lax, 1-sided raceme-like thyrse; pedicels with 2 small subulate bracteoles
Morphology Reproductive morphology Flowers Calyx
Calyx short, tubular, 2-lipped; lips broad, equal, entire, pressed together in fruit; posterior lip folded halfway along its length into a small erect scutellum which becomes larger, concave and sail-like in fruit, later deciduous to release mature nutlets; anterior lip persistent
Morphology Reproductive morphology Flowers Corolla
Corolla purplish or rarely yellow, posterior lip galeate enclosing the anthers and stigma; anterior lip entire, rounded; lateral lobes more closely joined to posterior lip than anterior; tube narrow, dilated at throat, bent sharply upwards at base or not, glabrous inside
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens attached ± halfway down corolla tube, anterior longer than posterior; filaments glabrous, parallel; anterior anthers dimidiate due to aborted development of upper thecae, posterior thecae convergent; anther slits bordered by cilia
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary glabrous, borne on a short peg-like gynophore, with a swollen, nectar-producing base; style bifid, posterior lobe much shorter than anterior
Morphology Reproductive morphology Fruits
Nutlets 4, 1–1.5 mm long, with a small ventral scar; embryo incumbent; endosperm absent.
