description: Elsholtzia griffithii Hooker (1885: 644, Fig. 2).
Type: — East Bengal, the late East India Company, Griffith W., 3975 (holotype: K!; isotype: P!).
Diagnostic characters: — Elsholtzia griffithii Hook. f. is morphologically similar to E. cyprianii (Pavol.) S. Chow ex Hsu, but can be distinguished from the former by its lanceolate bracts exceeding the flowers, 3.0–4.0 mm long; five calyx-lobes unequal, of which anterior two lobes shorter than three posterior lobes (vs. bracts up to 3.0 mm, generally shorter than flowers, calyx teeth equal in E. cyprianii).
Herbs annual, 15–60 cm tall. Stems simple, erect, 4-angled, densely retrorse pubescent or villous. Leaves opposite; petiole 0.5–2.0 cm; leaf blade oblong to ovate-oblong, 2.0–8.0 cm × 1.0– 2.5 cm, herbaceous, adaxially dark green, puberulent, abaxially densely pubescent, glandular, base broadly cuneate, decurrent, midrib prominent abaxially, lateral veins 4–6 paired, margin crenate-serrate to coarsely serrate, apex acute. Spikes cylindric, 8–15 × 0.5–1.0 cm, terminal, retrorse white pubescent; verticillasters compact; bracts lanceolate, 3.5–4.0 mm long, exceeding the flowers; pedicle nearly absent. Calyx green, tubular-campanulate, ca. 1.8 mm, densely white pubescent outside, teeth 5, lanceolate, ca. 0.8 mm long, anterior 2 calyx lobes shorten, and the posterior frontal lobe is longer than two lateral lobes. Corolla reddish or white, 2–2.5 mm, pubescent and glandular outside, glabrous inside; 2-lipped, upper lip entire or emarginate, middle lobe of lower lip circular, lateral lobes semicircular, margin entire. Stamens 4, straight, exserted from upper lip of corolla, 2 anterior stamens much longer, 3.0– 3.5 mm long, filaments filiform, glabrous. Style much exserted, 2.5–3.0 mm as long as posterior pair of stamens, apex equally two-cleft.
Phenology: —Flowering from May to August, fruiting from August to October.
Distribution and Habitat: — Bangladesh, China (Guangxi), India, Korea, Myanmar, Nepal, Thailand (Bongcheewin & Chantaranothai 2008; Hong et al. 2021). Elsholtzia griffithii is currently known from Huanjiang County of Guangxi Province in southern China. It grows on the rocks of field or on the roadside at an altitude of 264–314 m, together with Bidens pilosa Linnaeus (1753: 832), Acalypha australis Linnaeus (1753: 1004), Oxalis corniculata Linnaeus (1753: 435), Cayratia japonica (Thunb.) Gagnepain (1911: 349) etc. Elsholtzia griffithii is known only in two locations in Huanjiang County, Guangxi, further exploration may result in the discovery of additional localities for this species.
