Yuan 20210206001 (holotype, IBSC; isotypes: IBSC, KUN).</p> <p>Description.</p> <p>Perennial herbs or shrubs, 0.8-2 m tall. Stem erect, 6-8 mm in diameter, 4-angular, slightly dilated at nodes, a few branched, strigose, or villous at the upper part. Leaves opposite; blade ovate, rarely ovate-lanceolate, (5.5-) 9-13.5 × (2.5) 6.5-10.5 cm, papery or membranous, strigose on both surfaces, base broadly cuneate, margin obviously double serrate, entire at base, apex acuminate; midvein elevated abaxially, lateral vein 3-4 (rarely 5) pairs on each side of the midvein, slightly elevated abaxially; petioles (1.5-) 4-11.5 cm long, ca. 1 mm in diameter, strigose. Spikes of inflorescence (1.0-) 2.5-8.0(-10.5) cm long, 9-12 mm in diameter, terminal and axillary, interrupted basally in long spikes, usually with more than two lateral branches; peduncle (1-) 2-4 cm long, densely villous; verticillasters many-flowered, flowers sessile. Bracts oblong, 5-13 × 2.5-5 mm, strigose, midvein elevated abaxially, lateral vein 1-2 pairs on each side of the midvein or sometimes obscure; bracteoles ovate-lanceolate to narrowly lanceolate, 2.5-5 × 0.7-1.8 mm, strigose. Calyx tubular-inflated, 4-5 mm long, 5-veined, strigose and sparsely golden glandular outside, sometimes sparsely strigillose inside at the upper part of tube; teeth 5, narrowly triangular, equal, 1.8-2 mm long, 0.6-0.8 mm wide at base, 2/3 to subequal as long as the calyx tube, subglabours or strigillose inside. Corolla white, 6-7 mm long, exserted evidently from calyx, 2-lipped, upper lip 3-lobed, lower lip entire. Stamens 4, erect, much exserted from corolla; filaments 7-7.5 mm long, all inserted at a height of ca. 2 mm in the tube, bearded at middle, bearded portion exserted; anther 1-locular, cell apex dehiscent. Style 7-7.5 mm long; stigma bifid, lobes subequal, 1.2-1.7 mm long. Disc ca. 0.6 mm long. Nutlets 4, ca. 0.7 × ca. 0.6 mm long, ellipsoid or slightly depressed globose, abaxially slightly flat, adaxially ribbed, black or dark brown.</p> <p>Etymology.</p> <p>Pogostemon hainanensis is named after its type locality, Hainan province, China.</p> <p>Phenology.</p> <p>Flowering from December to the next February and fruiting from January to April.</p> <p>Paratype.</p> <p>China.
