Conservation
Least concern. Pycnostachys ciliata has a broad distribution and has been recently collected from a wide range of localities within it.
Distribution
Africa. Tanzania (FTEA regions: TI, T2, T4, T5, T7, T8); Zambia (FZ regions: N, C); Malawi (FZ regions: N, C) ; Mozambique (FZ region: N).
Ecology
Dry areas such as Brachystegia woodland, Combretum woodland on sandy soils, also hillsides; c. 900 -1800 m.
Morphology General Habit
Annual herb, 30-150 cm
Morphology Leaves
Leaves opposite, sessile; blades narrowly elliptic to narrowly ovate to lanceolate, 65 - 155 x 8-45 mm, serrate, apex acuminate, base gradually narrowing (attenuate) to the stem, chartaceous, with yellow and red sessile glands and pubescent with short, stiff eglandular hairs, the hairs more plentiful on the venation below
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens connate for c. 2 mm until the posterior pair curves upwards sharply, exserted for 1-2 mm, the anterior pair curving upwards more gradually until exserted nearer to the end of the lip
Morphology Reproductive morphology Flowers Calyx
Flowering calyx with tube c. 1 mm long, outer surface with eglandular hairs and scattered yellow and red sessile glands; lobes 5, subulate, c. 1.5-3 mm long, with longer eglandular hairs especially near the lobe bases and occasional red sessile glands Fruiting calyx with tube 3-7 mm long, somewhat ventrally gibbous, lobes more or less patent, becoming thicker and more rigid, variable in length, 3-7 mm, inner surface with 0.5 - 1 mm long rounded triangular scales visible between calyx lobes
Morphology Reproductive morphology Flowers Corolla
Corolla pale blue, 11 - 14(- 18) mm; tube with short eglandular hairs, very narrow and parallel sided for 5-6 mm, then curving sharply downwards and broadening for 4-6 mm before opening into two lips; posterior lip shorter than anterior, 2-3 mm long, divided into 4 lobes c. 0.5-1 mm long, the inner two lobes slightly broader than and overlapping with the outer two, with eglandular hairs and red sessile glands; anterior lip 5 - 7(9) mm long, 3-4 mm deep, partially enclosing stamens, with eglandular hairs and red sessile glands on the front of lip
Morphology Reproductive morphology Flowers Disc
Disk with anterior lobe longer than ovary, c. 1 mm long, three posterior lobes much shorter
Morphology Reproductive morphology Fruits
Nutlets black or dark-brown, broadly elliptic and slightly flattened, c. 1.5 mm long, darkly gland dotted, mucilaginous when wet.
Morphology Reproductive morphology Inflorescences
Inflorescence dense, when in flower forming a narrowly conical shape, becoming more cylindrical in fruit, 40-140 x 18-30 mm, usually with a sterile, bracteate extension with elongated axis up to 20 mm long at the tip; flowers sessile in single flowered cymes; bracts subtending entire inflorescence narrowly ovate, 15 - 35 mm long, apex acuminate, enclosing buds then becoming deflexed in flower, pubescent and ciliate with short eglandular hairs, persistent through flowering stage; bracts subtending single flowers linear or linear-lanceolate, 5-8 mm long, conspicuously and densely ciliate with eglandular hairs, these as long as the bracts are wide
Morphology Stem
Stems erect, quadrangular, pubescent with short, downward pointing eglandular hairs and red sessile glands, these more plentiful on younger growth
Note
This new species covers a considerable amount of material that had been identified either as Pycnostachys deflexifolia Baker or P. speciosa Gurke. Indeed, P. dliata is apparently closely related to both of these species and shares with them conspicuous ciliate bracts and similar leaf morphology. However, it differs from P. deflexifolia because it has a larger calyx and corolla (11-14 [18] mm rather than 6-7 mm), and it is found in much drier habitats (P. deflexifolia is found in wetter, more waterlogged soils). Pycnostachys dliata is distinct from P. speciosa because of its smaller calyx (flowering calyx tube 1 mm, lobes 1.5-3 mm rather than tube 1.5 mm, lobes 5-6 mm), and it is much less robust. In addition P. ciliata has a sterile extension to its inflorescence consisting of bracts along an elongated axis, and a more southerly distribution (southern Tanzania and nor then Zambia rather than Uganda, Kenya and northern Tanzania). There is some variation in corolla size: typically the corolla is 11 - 14 mm long, but some specimens have larger corollas measuring 18 mm (e.g. Richards 24466).
Type
Tanzania, T7, Mbeya Distr., Songwe Valley, c. 2 km N of Mbeya - Tunduma rd, 8°57'S 33°14'E, 1200 m, 25 March 1988, Bidgood, Mwasumbi & Valiesen 693 (holotypus K!; isotypi DSM, NHT, C).

Note
This species covers a considerable amount of material that was either described as P. deflexifolia or P. speciosa. Indeed, P. ciliata is closely related to both of these species and shares with them extremely conspicuous ciliate bracts. However, it differs from P. deflexifolia because it has a larger calyx and corolla (11–14(–18) mm vs 6–7 mm), and it is found in much drier habitat ( P. deflexifolia is found in wetter, more waterlogged soils), and it is distinct from P. speciosa because of its smaller calyx (flowering calyx tube 1 mm, lobes 1.5–3 mm vs tube 1.5 mm, lobes 5–6 mm), and it is much less robust. In addition P. ciliata has a sterile extension to its inflorescence consisting of a coma of bracts along an elongated axis, and a more southerly distribution (southern Tanzania, northern Zambia, Malawi and Mozambique vs Uganda, Kenya and northern Tanzania). There is some variation in corolla size, e.g. Richards 24466 from northern Zambia ± 18 mm long.
