Descriptions
Parahebe decora Ashwin
Prostrate much-branched subshrub forming dense to loose matted patches; stems slender, ± woody, sts rooting at nodes, giving off small appressed lfy branches 2-5 cm. long, all uniformly pubescent with crisped white hairs. Lvs close-set to distant, often reddish and ± fleshy when fresh; lamina 1·5-4-(5) × 1-3-(5) mm., ovate to suborbicular, entire or once-lobulate at base, rarely with 2 pairs of crenations, broadly rounded at tip, glab., abruptly narrowed into stout ± ciliate grooved petiole 1-1·5 mm. long with line of pubescence above. Racemes 6-10-(15)-fld, lowest fls us. in remote whorl of (2)-3; peduncles stout, up to 15 cm. long, glab. or rarely sparsely pubescent; bracts 1-2 mm. long, narrow-ovate, glab. or sparsely ciliolate; pedicels 2-10 mm. long, glab. or sparsely pubescent. Calyx-lobes 2-3 mm. long, ovate, acute to subacute, finely ciliolate. Corolla white to pink, c. 1 cm. diam.; tube barely 1 mm. long, much < calyx; lobes 4, unequal, spreading, obtuse or anterior one emarginate. Capsule c. 4-5 × 3-4 mm., much > calyx, broad-oblong, emarginate, us. turgid, glab.

Parahebe decora Ashwin
Subshrub (sometimes small and creeping), (1–)2–3 cm tall. Old stems brown to grey. Branches prostrate or decumbent. Branchlets redbrown to black. Vegetative internodes (0.5–)1–5(– 15) mm long. Stem pubescence uniform or bifarious (rarely), eglandular pubescent (hairs curly). Leaves decussate, spreading to recurved. Lamina obovate to orbicular or lyrate, 1.5–4(–5) × 1–3(–5) mm. Adaxial surface of leaves green to dark green (often redtinged), glossy. Abaxial surface of leaves pale green or pinkish, dull. Leaf hairs sparse or numerous (rarely), along margins (rarely) or on petiole or on adaxial surface (rarely) or on abaxial surface (rarely), uniseriate eglandular (curly). Apex rounded. Base cuneate. Margin glabrous, crenate or lobed. Marginal teeth or lobes in 1(–2) pairs. Petiole (0.5–)1–1.5 mm long. Inflorescence racemose, unbranched, (6–)15– 20(–25) cm long at fruiting, with (3–)8–20 flowers. Indumentum of peduncle, rachis, and pedicels absent to moderately dense. Eglandular hairs of inflorescence antrorse, white. Peduncle (4–)8–15 cm long, glabrous to eglandular-pubescent; hairs all around peduncle. Rachis (2–)7–10 cm long, eglandular-pubescent, hairs all around rachis. Bracts alternate (spiralled) to alternate but with a basal whorl of 3 (or rarely several whorls of 3), obtuse to subacute, eglandular ciliate (especially near base), lanceolate to elliptic. Bract margins entire. Pedicels erectopatent at anthesis to suberect at anthesis, straight at fruiting, 2–10 mm long, glabrous or eglandularpuberulent; hairs all around pedicel. Flowers: Calyx 4-lobed, 2–2.5(–3) mm long. Calyx lobes oblanceolate to obovate, acute to subacute. Calyx hairs on margins only, mixed eglandular and glandular. Calyx lobe margins entire. Corolla white at anthesis or pink at anthesis. Nectar guides evident, confined to posterior corolla lobe or present on posterior and lateral corolla lobes. Colour ring and nectar guides magenta. Corolla throat yellow. Corolla 6–8(–12) mm diam. Corolla tube 1 mm long, 1 mm wide, hairy inside, hairs short. Corolla lobes glabrous. Posterior corolla lobe circular, obtuse, (3–) 3.5–5(–6) × (3–)4–6(–7) mm. Lateral corolla lobes circular to elliptic, obtuse, longitudinally folded around stamens, 4–4.5 × 3.5–4 mm. Anterior corolla lobe oblong to linear, obtuse, 4–5 × 1–2 mm. Stamen filaments white, 3–4(–5) mm long, narrowed at base. Anthers white or pink or magenta, 0.9–1.2 mm long. Nectarial disc ciliolate. Ovary ellipsoid, obtuse, glabrous, 1–1.5 mm long. Style (3–)3.5–4 mm long. Stigma 0.15 mm wide. Capsules xerochastic, broadly angustiseptate (i.e., weakly flattened), emarginate, 4–4.5 × 3–4 mm, 2–2.5(–3) mm thick, glabrous. Septicidal split of capsule extending to base. Loculicidal split of capsule extending 1⁄2–3⁄4 way to base. Seeds approx. 20–30 per locule, strongly flattened, smooth-surfaced, ellipsoid to discoid, straw yellow to pale brown, 0.8–0.9 × 0.6– 0.8 mm.
