Perennial herbs, erect to decumbent, up to 75 cm high. Stems well-branched towards apex, 4-angled when young, cylindrical with 4 wings when old; internodal distance 0.8–3.2 cm long, glabrous throughout except hairy nodes. Leaves sessile, decussate, linear to narrowly elliptic, 4.2– 12 × 0.6–1.1 cm, base rounded, margins entire to serrulate due to swollen hair bases, acute and mucronulate at apex, glabrescent on upper surface, pubescent at veins of lower surface; venation eucamptodromous, midvein broad at base, lateral veins 3–8 pairs, conspicuous on lower surface. Spike basal and in the lower axils of branching nodes, compounded into dense synflorescences to form globose heads or cushions with scale-like sterile bracts at the base, each up to 6 cm in diam. Bracts: sterile ones in 4–10 (2–5 pairs) at the base of each spike, lanceolate to lance-ovate, 10.2–11.5 × 1.8–3.3 mm, base truncate, margins sparsely ciliate, apex acuminate with spinose apical process, sparsely sericeous throughout; fertile bract 1 per flower, lance-ovate to narrowly oblong, 11–13.6 × 1.8–3.5 mm, base obtuse or truncate, margins ciliate with short glandular hairs towards apex, apex acuminate to cuspidate with spinose process, sericeous hairs on outer surface, glabrescent on inner surface. Bracteoles 2 per flower, heteromorphic, lanceolate to oblanceolate, 11.3–14.2 × 1.4–2.3 mm, base cuneate or obtuse, margins ciliate with short glandular hairs towards apex, apex acuminate with spinose process, sericeous at midvein of outer surface, glabrescent on inner surface. Calyx 5-lobed; lobes heteromorphic, acuminate or caudate at apex, margins ciliate with short glandular hairs intermixed towards apex, sericeous throughout; anticous lobes 2, elliptic (oblong in fruiting calyx), 8.5–13 × 3–4 mm, connate at base (almost three quarters of its total length, i.e., 4.2– 9.7 mm), overlapping; posticous lobe 1, elliptic to oblanceolate-ovate (oblong in fruiting calyx), 8.9–13.9 × 2.7–4 mm; lateral lobes 2, linear, 7–12.2 × 0.8–1.9 mm. Corolla bilabiate, 9.6–13.5 mm long, pinkish white with many purple markings on throat and limb inside and yellowish brown dots or patches on the palate; tube 6.3–6.7 mm long, cylindric below, 3.3–3.8 mm long, glabrous inside, abruptly expanded above, 2.7–2.9 mm long, retrorsely hairy outside; upper lip arcuate, 1.5–1.9 × 2.5–3.2 mm, entire at margins, minutely 2-lobed ( 0.2–0.35 mm long) at apex, each lobe 3-veined; lower lip 3-lobed, with a membranous portion on either side of the centre of the palate with an adjacent line of silky hairs, 3.3–4.5 mm long, including lobes, lobes spreading at throat for 5.9–7.1 mm long; middle lobe broader than the lateral lobes, sub-orbicular, 1.9–2.3 × 3.2–3.7 mm, crenulate, 3-veined; lateral lobes broadly oblong, 2–2.2 × 1.8–2.5 mm, 3-veined. Stamens 4, didynamous, adnate at the base of expanded corolla tube; filaments purple to white, glabrous; anticous (longer) filaments 1.3–1.7 mm long; posticous (shorter) filaments 1–1.2 mm long; anthers oblong, 0.7–1 mm long, white, sparsely hairy at base of the suture, scabrous at the connectives, longitudinally dehiscing. Ovary sub-globose, c. 1.3 × c. 1 mm, glabrous, 2-loculed; ovules 2 in each locule; nectary disk cupulate; style 6–6.2 mm long, bristled glandular-hairy; stigma entire to bilobed. Capsules ovoid in face view, 6.5–7.5 × 3.1–3.5 mm, glabrous, green to yellowish-brown; retinacula c. 1.6 mm long. Seeds 2 or 1 per capsule, fertile, ovoid in face view, 3.7–3.9 × 2.7–3.2 mm, flat, densely clothed with hygroscopic white hairs (longer than seeds) on both surfaces.
Flowering & fruiting: Flowering from October to January and fruiting from November to February. Habitat: This species usually grows on grasslands with sandy or gravelly soils, at elevations ranging from 250 to 390 m.
Distribution: Endemic to India. A critical study of the description provided in the state and regional Floras of India, and examination of specimens housed at the national and international herbaria (digital images) show that this species is endemic to India with an almost country-wide distribution, except for the northeastern region. The species is distributed in the following states: West Bengal ( Nees von Esenbeck, 1832; Prain, 1903), Punjab ( Nair, 1978), Rajasthan (Pandey & Singh, 1991), Odisha (Saxena & Brahmam, 1995), Uttar Pradesh (Sharma & Dhakre, 1995), Andhra Pradesh (Pullaiah & Moulali, 1997), Madhya Pradesh ( Khanna et al., 1997), Bihar (Singh et al., 2001), Maharashtra ( Moorthy, 2001), Chhattisgarh ( Khanna et al., 2005), Jharkhand (Paria & Chattopadhyay, 2005) and Telangana ( Pullaiah, 2015). During the present study, a specimen of L. hamiltoniana was collected from Dahod and Kutch districts in Gujarat. The occurrence of this species has never been reported from the state until now, thus the present collection forms an addition to the flora of Gujarat state. However, a critical scrutiny of the description provided in the ‘Flora of Gujarat State’ by Shah (1978) shows that this species was erroneously identified and documented as L. cristata . Furthermore, we have come across a specimen of this species collected from Mysore (MH [MH00110039]), which forms a new record of distribution of this species to the flora of Karnataka. However, an extensive field exploration is required to confirm its present distribution in Karnataka.
