DESCRIPTION

Perennial. Woody at base, more or less glandular-pubescent in upper internodes. Stems few, erect, cream, thick, sometimes viscous, 75-100 cm high, branching usually above the middle; internodes 1.5-10 cm long. Lower leaves 30-80 × 7-17 mm, oblanceolate, tapering at base, acute to obtuse, light green sometimes; middle leaves 60-70 × 20-30 mm, ovate narrowed at base; upper leaves 10-50 × 2-17 mm, lanceolate, acute. Inflorescence lax, compound dichasia. Bracts 1.5-4 mm long, lanceolate to ovate, acuminate, ciliate, glandular- pubescent on the lower surface especially on midrib, scarious with a green or purple midrib. Pedicels 7-20 mm long, glandular-pubescent. Calyx tubular-campanulate, 6-10 mm long, incised from one third to the middle with narrow triangular acute teeth, glandular-pubescent, with crowded large crystals. Petals 11-17 mm long, narrow cuneate, truncate, white with purple veins. Stamens 10, unequal, longer than calyx. Ovary elliptic; styles two, parallel; ovules 16-24. Capsule ovate, about 4.5-6 mm long, up to 14 seeded; seeds 1.6-2 × 1.7-2 mm, reniform, with marginal hilum, with obuse to acute tubercles, with glossy surface. In terms of exomorphology, the surface of the seed is constructed of regularly arranged elongate cells with sinuate margins and convex periclinal walls.

POLLEN MORPHOLOGY

Monade, apolar, rounded polyhedral-spheroidal, 30.5-31.5 µm. Grains pantoporate. Pores 3.5-4 µm. in diameter, annulate. Distance between pores (without annulus) 5.5-6 µm. Annulus with granules, operculate. Ornamentation is nanoechinatenanoperforate ( Fig. 6E, F ).
