Morphology General Habit
Perennial herbs, with trailing or procumbent branches radiating from a small woody base; stems markedly angular with 2 opposite pairs of ridges
Morphology Leaves
Leaves opposite-decussate, sessile or very shortly petiolate, pairs isophyllous, blade obovate or obovate-elliptic; cystoliths present, shortly linear, numerous but often inconspicuous
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 2, inserted on ventral side of corolla tube just below the corolla mouth; filaments short; anthers shortly exserted, held ± adpressed to the lower lip, dehiscing toward upper lip (i.e. flowers stenotribic), bithecous, thecae ± parallel, slightly offset, lacking basal appendages; staminodes absent
Morphology Reproductive morphology Flowers Calyx
Calyx shortly tubular, deeply divided into five lobes, these subequal, linear-lanceolate with hyaline margins, shorter than the bracteoles
Morphology Reproductive morphology Flowers Corolla
Corolla with rugula present, comprising two slender ciliate ridges extending from near base of corolla tube to proximal portion of upper lip; tube slender, longer than limb, gradually widened towards the mouth; aestivation ascending-cochlear, limb bilabiate; upper lip ovate or elliptic, apex shortly bilobed or emarginate, lower lip conspicuously 3-lobed, palate with faint raised venation
Morphology Reproductive morphology Flowers Disc
Floral disk cupular, ± 0.5 mm tall, with unevenly undulate margin
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary oblong-ellipsoid, 4-ovulate; style filiform; stigma minutely bilobed, one lobe slightly larger than the other
Morphology Reproductive morphology Fruits
Capsule 4-seeded (or fewer by abortion), retinaculate, stipitate and with attenuate apex; seeds tuberculate.
Morphology Reproductive morphology Inflorescences
Inflorescences axillary, sessile or shortly pedunculate fasciculate cymes of (1 –) 2 – 3 flowers, bracts and bracteoles paired, linear-lanceolate, green with hyaline margins
Note
Kenyacanthus is recognised by having the combination of a trailing or procumbent habit; fasciculate inflorescences; bracts, bracteoles and calyces with hyaline margins; a bilabiate corolla with a slender cylindrical tube longer than the limb and with a shallow rugula; and two stamens held against the lower corolla lip and anthers with slightly offset thecae, the flowers being stenotribic. It differs from Rhinacanthus primarily in the trailing or procumbent habit; hyaline margins to the bracts, bracteoles and calyx lobes; two corolla lips of subequal size; stenotribic flowers and essentially glabrous capsules (vs plants erect, decumbent or straggling; bracts etc. lacking hyaline margins; upper corolla lip markedly smaller and narrower than the lower lip; flowers nototribic and capsules puberulous to pubescent in Rhinacanthus). It differs from Dicliptera primarily in the combination of a straight, untwisted corolla tube and stenotribic flowers (vs corolla tube twisted through ± 180° such that the corolla is resupinate, or if corolla tube untwisted then flowers nototribic in Dicliptera); it also differs from all African Dicliptera in the anther thecae being only partially offset (vs fully superposed). Kenyacanthus is named in honour of the Republic of Kenya, to which this genus is apparently endemic based on current evidence.
