Descriptions

Scrophulariaceae, S.A. Ghazanfar, F.N. Hepper & D. Philcox. Flora of Tropical East Africa. 2008

Morphology General Habit
Herbs, aquatic or in marshes, often aromatic on bruising, glabrous, pubescent or glandular.
Morphology Stem
Stems erect, simple or more usually branched, ± submerged, prostrate and rooting at nodes
Morphology Leaves
Leaves of two types with one or both types on the same plant: submerged leaves finely divided, verticillate; aerial leaves undivided or variously laciniate, opposite or verticillate; ± punctate
Morphology Reproductive morphology Flowers
Flowers sessile or pedicellate, solitary in the axils or in lax or compact, terminal or axillary spikes or racemes; bracteoles 0 or 2
Morphology Reproductive morphology Flowers Calyx
Calyx tubular, 5-lobed, lobes unequal, tube with 0–5 prominent veins or striate with more than 10 prominent veins present at maturity
Morphology Reproductive morphology Flowers Corolla
Corolla tubular or funnel-shaped, 5-lobed, bilabiate; upper (adaxial) lip outside in bud, entire or 2-lobed; lower (abaxial) lip 3-lobed
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 4, didynamous, included, posterior pair shorter; anthers free, loculi stipitate
Morphology Reproductive morphology Flowers Gynoecium
Ovary glabrous; stigma bilamellate;  style filiform, deflexed at the apex
Morphology Reproductive morphology Fruits
Capsule ellipsoid to globose, septicidally 4-valved
Morphology Reproductive morphology Seeds
Seeds numerous.
Note
All the species represented here are heterophyllous, bearing both aerial entire leaves and, in an aquatic state, divided filamentous submerged leaves; as such, all occur in section Limnophila (see Philcox in K.B. 24: 107 (1970)).
