Morphology General Habit
Perennial herbs or subshrubs, erect or decumbent; young stems somewhat 4- or 6-angular
Morphology Leaves
Leaves opposite-decussate, petiolate, pairs isophyllous, blade ovate or oblong-ovate to elliptic or oblong-elliptic; cystoliths present, linear, numerous, conspicuous in dry state at least on adaxial leaf surface
Morphology Reproductive morphology Flowers
Bracts (excluding those pairs at base of inflorescence spike), bracteoles and calyx lobes subequal in size and shape, linear, linear-spathulate or linear-lanceolate; flowers subsessile or shortly pedicellate
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 2, inserted on interior of corolla tube, anthers exserted, dehiscing toward lower lip (i.e. flowers nototribic), bithecous, thecae parallel or slightly oblique, very slightly to more markedly offset, both thecae with a flattened, broad, irregularly toothed appendage at the base; staminodes absent
Morphology Reproductive morphology Flowers Calyx
Calyx divided almost to base into five lobes, subequal to somewhat unequal in length
Morphology Reproductive morphology Flowers Corolla
Corolla intricately speckled and/or striped, rugula absent; aestivation ascending-cochlear, limb bilabiate; upper lip with apex shortly bilobed, lower lip 3-lobed
Morphology Reproductive morphology Flowers Disc
Floral disk annular, fleshy, 0.5 – 0.7 mm tall
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary oblong-ellipsoid, 4-ovulate; style filiform; stigma shortly bilobed
Morphology Reproductive morphology Fruits
Capsule (where known) 4-seeded (or fewer by abortion), retinaculate, stipitate; seeds (only seen in immature state) tuberculate.
Morphology Reproductive morphology Inflorescences
Inflorescences terminal, spiciform, comprising a series of opposite subsessile or shortly pedunculate cymes arranged along an indeterminate axis, i.e. a spiciform thyrse
Note
Champluviera is recognised by having the combination of a dense spiciform terminal thyrse with the bracts, bracteoles and calyx lobes all slender and closely resembling one another; a bilabiate corolla lacking a rugula and with intricate speckling or striping on the lips; and, in particular, anthers comprising two slightly to more markedly offset thecae each of which has a broad flattened basal appendage with an irregular fringe, and at least the upper theca having a line of trichomes on the exposed side. It differs from Schaueria primarily in having appendaged and pubescent anthers and in having speckled or striped corolla lips (vs anthers lacking appendages and glabrous, corollas not speckled or striped). It differs from Justicia primarily in the corolla lacking a rugula and in the anther appendages being broad and irregularly toothed (vs corolla with a rugula, anther appendages elongate to rounded and smooth except sometimes for a forked apex). Champluviera populifolia also has an apparently unique pollen type in which the two pseudocolpi of each mesocolpium converge towards the equator and sometimes meet, forming an hour-glass or figure eight shape. This genus is named in honour of Dr Dominique Champluvier (previously of the BR herbarium), an expert on the Acanthaceae of Africa with a particular interest in the Central African region. Dominique was the first to recognise the close relationship between the two species in this new genus.
