Fuse &amp; Yahara subsp. nov.</p> <p>Fig. 4</p> <p>Diagnosis.</p> <p>Stellaria alsine subsp. nana differs from the typical subspecies in its shorter stem (2.5-6 cm vs. 15-30 cm), smaller lamina (0.5-1 cm × 1-3 mm vs. 0.5-2 cm × 2-4 mm), shorter pedicels (0.1-0.6 cm long vs. 0.5-2 cm long), as well as chasmogamous flowers with 3 stamens and 2 styles (vs. 5 stamens and 3 styles) that are usually solitary (vs. usually 3-5 on a terminal or axillary cyme).</p> <p>Type.</p> <p>Japan.

Higashi JPN0573 (holotype: FU!, isotype: KYO!).</p> <p>Description.</p> <p>Herbs possibly biennial. Stems caespitose, 2.5-6 cm long, glabrous, erect in upper and middle parts, prostrate in lower parts. Leaves deciduous, sessile; blade oblong-obovate or narrowly obovate, 0.5-1 cm × 1-3 mm, glabrous, single-veined, base attenuate, apex acute, margin entire. Flowers solitary or 2-3 flowers in an axillary or terminal cyme with a ca. 6 mm scape. Pedicel 1-6 mm long, slender, glabrous. Sepals ovate-lanceolate, ca. 2.5 mm long in chasmogamous flowers, ca. 2.0 mm long in cleistogamous flowers, glabrous, apex acute. Petals of chasmogamous flowers 5, ca. 2.6 mm long, 2-cleft nearly to base; lobes oblanceolate, apex obtuse; petals absent in cleistogamous flowers. Stamens of chasmogamous flowers 3, 0.8 mm long; filaments ca. 0.4 mm long, glabrous, anthers globular, 0.4 mm in diam. Styles 2, glabrous. Capsule obovoid, 2.5 mm long, as long as sepals when mature, 2-loculated. Seeds dark brown, reniform, ca. 0.7 mm long, slightly flattened, tuberculate with raised papillae, without an appendage.</p> <p>Phenology.</p> <p>Chasmogamous flowers were observed in May, cleistogamous flowers and immature fruits were observed in July, and mature fruits and seeds were observed in September.</p> <p>Distribution and habitat.</p> <p>Yakushima, Japan (endemic). At present, this subspecies has been identified in two populations growing on rocks along streams at 1500 m elevation in the vicinity of Mt. Nagata.</p> <p>Etymology.</p> <p>The subspecific epithet is derived from its dwarf habit.</p> <p>Conservation status.</p> <p>Vulnerable (VU). The population size was estimated to be between 250 and 1000 mature individuals. The habitat is located within the protected area of Yakushima (Island) National Park and no threats are detected at present.</p> <p>Additional specimens examined.</p> <p>Japan.
