Type
Type: Kenya, Naivasha District: near Lake Elmenteita, Scott Elliot 6756 (K!, holo.)
Morphology General Habit
Annual herb, 0.5–2 m tall
Morphology Stem
Stems erect, quadrangular, pubescent with short downward-pointing eglandular hairs and red sessile glands, these more plentiful on younger growth
Morphology Leaves
Leaves opposite, sessile or subsessile; blades very narrowly to narrowly elliptic or narrowly ovate to lanceolate, 4.5–15 × 0.7–3.5 cm, serrate, apex acuminate, base gradually narrowing and attenuate to the stem, with yellow and red sessile glands and pubescent with short, stiff eglandular hairs, the hairs more plentiful on the venation beneath
Morphology Reproductive morphology Inflorescences
Inflorescence dense, when in flower forming a very narrow conical shape, in fruit 40–55 × 18–22 mm; bracts subtending entire inflorescence narrowly ovate, 15–60 mm long, acuminate, enclosing buds then becoming deflexed in flower, pubescent and ciliate with short eglandular hairs, persistent through flowering stage; bracts subtending single flowers ± linear, 5–6 mm long, conspicuously ciliate
Morphology Reproductive morphology Flowers Calyx
Calyx with tube ± 1 mm long at anthesis, outer surface with eglandular hairs and scattered yellow and red sessile glands, inner surface with 0.5 mm long rounded-triangular scales present between calyx lobes; lobes 5, subulate, ± 2 mm long, with eglandular hairs and occasional red sessile glands; fruiting calyx with tube 3.5–4 mm long, ventrally gibbous, the scales between the lobes conspicuous, lobes somewhat curved, variable in length, 4–5(9–12) mm
Morphology Reproductive morphology Flowers Corolla
Corolla white or pale blue or purple, 6–7 mm long; tube with red sessile glands and eglandular hairs, very narrow and parallel-sided for 2 mm, then curving sharply downwards and broadening for 1 mm before opening into two lips; posterior lip shorter than anterior, 1–1.5 mm long, with eglandular hairs and red sessile glands; anterior lip 2–2.5 mm long, 1 mm deep, margins somewhat undulate, with eglandular hairs and red sessile glands on the front of lip
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens connate for ± 0.5 mm, barely exserted
Morphology Reproductive morphology Fruits
Nutlets ± 1.5 mm long.
Ecology
Acacia or Brachystegia woodland or wooded grassland, often on wet ground; 1500–2300 m
Conservation
Least concern; known only from the Rift Valley region of East Africa, but does not appear to be unduly threatened
Note
Pycnostachys deflexifolia is distributed throughout the Rift Valley, and is closely related to P. speciosa and P. ciliata. The species are all recognisable due to their conspicuous, densely ciliate bracts. However, P. deflexifolia can be distinguished from these species by its smaller flowers and leaves which are somewhat deflexed, and it tends to be found in wetter areas.
