Morphology General Habit
Annual or biennial herbs 0.2–1.3 m tall.
Morphology Stem
Stems erect, smooth, slender, light green, with single or multiple stems arising from the plant base, sometimes woody basally; vegetative parts viscid-pubescent with long and short spreading hairs, eglandular or glandular
Morphology Leaves
Leaves membranaceous or fleshy, usually pinnatisect, occasionally pinnate or deeply lobed, extremely variable in size from 1.8–5.8(–12) × 0.3–3.8 cm overall, pinnae or segments 0.3–1.2(–2.7) cm × 1–4(–7) mm, usually in 4–9 alternating pairs, linear to ovoid with ± obtuse apices, sessile bases and margins deeply lobed or sinuate, occasionally entire, pubescence denser on veins and lower leaf surfaces, hairs mostly eglandular; petioles absent or to 18 mm long. Inflorescences terminal, many-flowered cymes; flowers zygomorphic, 9–17 mm long; peduncles erect, to 3 cm long; pedicels arising in axil of leaf or small oval bract, erect, occasionally deflexed in fruit, somewhat filiform, 0.7–2.2 cm long in flower, densely viscid, becoming more sparsely pubescent in fruit when 1.8–4.2 cm long
Morphology Reproductive morphology Flowers Calyx
Calyx ± campanulate, 4–9 mm long, calyx lobes ligulate to spatulate with obtuse and sometimes recurved apices, (3.5–)4.5–8 × (0.6–)0.8–2 mm, becoming accrescent around capsules, viscid-pubescent externally
Morphology Reproductive morphology Flowers Corolla
Corolla usually purple or white but varying from blue, pink, red or yellow in cultivars, often with a yellowish throat, cylindrical basal tube shorter than calyx, 2–3 mm long, flaring above into 5 unequal deeply lobed obtuse segments: one anterior which often speckled or striped, two lateral and two posterior, fused to form a keel, pubescent externally, glabrescent internally, 9–17 × 0.8–2.7 mm diameter
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens subequal with two fertile and three staminodes one of which often minute; filaments free for 3–7 mm; anthers yellowish or purple-tinged, 1.2–2 mm long; staminodes with filaments free for 1–2 mm, white to cream, 0.3–0.5 mm long
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary glabrous, brownish, ovoid, 1.5–2 × 0.6–1.3 mm; style 8–12 mm long, often curved; stigma brownish, 0.2–0.3 mm diameter
Morphology Reproductive morphology Fruits
Fruit a smooth pale brown capsule, globose to ovoid, (3–)4–6 × (2–)3–5 mm, usually clasped by calyx lobes, often dehiscing apically by two or occasionally by three or four shortish slits
Morphology Reproductive morphology Seeds
Seeds brown, subspherical, 0.7–1 mm diameter, ridged around deep pits

Ecology
Cultivated and naturalised (no habitat details); ± 1700 m
Conservation
Widespread; least concern (LC)
Note
This is the most common and variable of the Schizanthus species, with many horticultural forms and varieties being distinguished by stem height and by the flower colour markings. The flowers are mostly bee-pollinated.
