The Ryukyus, the Okinawa Islands, Okinawa Island, Onna, 2 October 1949, Tawada 2221 (holotype US!; available from: http://collections.mnh.si.edu/search/botany/?ti=3).</p> <p>Description: —Herbs perennial, 3–5 cm tall. Stems not articulated, diffuse, branched basally, ca. 1 mm thick; basal stems woody, prostrate, upper stems herbaceous, upright, reddish green. Root fleshy, much-branched. Leaves spirally arranged to alternate, subsessile, without axillary hairs; leaf blade 2–3 mm thick, oblong to obovate, 5–8 mm long, base obtuse, apex obtuse or rounded. Flowers solitary, about 10–15 mm in diameter. Sepals 2, ovate-deltate, about 2 mm long. Petals 5, obovate to nallowly obovate, orangey yellow, mostly without margins overlapping. Stamens 12–15. Ovary ovoid. Stigma usually trilobed or tetralobed; capsule glossy, 2–4 mm long, 2–3 mm wide.</p> <p>Distribution and habitat:—The Ryukyus, the Okinawa Islands, Okinawa, Aka, Geruma, Tonaki islands. Coastal rocky slopes, xeric, saline, and exposed to direct sunlight. Portulaca okinawensis has also been recorded from Aka, Geruma, Yakabi, Tonaki, Aguni, and Kume islands of the Okinawa Islands (Shinjo &amp; Shinzato 2006). We have not collected samples from these islands. We examined a herbarium specimen of P. okinawensis collected from Yakabi Island (Miyagi 8414, RYU, collected in 1978) but we could not identify it at variety level because of the difficulty in counting of the number of stamens and the discoloring of the petals and stems.</p> <p>Additional specimens examined:— JAPAN.

The Ryukyus, the Amami Islands, Amami Island, Yamato, 6 September 2012, Kokubugata 15198 (holotype TNS!).</p> <p>Diagnosis: —Differt a var. okinawensi staminibus 12–15, petalis citrinis, obovatis vel oblanceolatis, caulibus viridibus.</p> <p>Description: —Herbs perennial, 3–5 cm tall. Stems not articulated, diffuse, branched basally, ca. 1 mm thick; basal stems woody, prostrate, upper stems herbaceous, upright, bright green. Root fleshy, much-branched. Leaves spirally arranged to alternate, subsessile, without axillary hairs; leaf blade 2–3 mm thick, oblong to obovate, 5–8 mm long, base obtuse, apex obtuse or rounded. Flowers solitary, about 10–15 mm in diameter. Sepals 2, ovate-deltate, about 2 mm long. Petals 5, obovate, emarginate, rotund to obtuse, lemon-colored, with margins overlapping. Stames 12–15. Ovary ovoid. Stigma usually trilobed or tetralobed; capsule glossy, 2–4 mm long, 2–3 mm wide.</p> <p>Etymology:— The epithet refers to the Amami Islands, the locus classicus.</p> <p>Distribution and habitat:—Endemic to the Amami Islands (the Ryukyus), in Amami and Tokuno-shima islands. Coastal rocky slopes, xeric, saline, and exposed to direct sunlight. In Kakeroma Island, being an islet situated in the Amami Island, P. okinawensis has been recorded. However, we could not obtain and investigate samples from the island.</p> <p>IUCN Red list category: —It can be included in the Data Deficient (DD) category of IUCN Red List categories (IUCN 2010) as there are inadequate information to make a direct or indirect assessment of its risk of extinction based on its distribution and/or population status.</p> <p>Additional specimens examined (paratypes):— JAPAN.
