| Description: |
Perennial, 7–38 cm tall, glabrous; stoloniferous, rarely subcaespitose, with stolons to 15 cm long. Stem with numerous basal and 2–3 cauline flat leaves; basal leaves 2.5–25 cm × 1.5–7 mm; cauline leaves 5–10 cm × (2–) 3.5–7 mm, sparsely pubescent to subglabrous at margins, without a mucronate projection on callose tip. Inflorescence terminal, compound, rarely in a few plants simple; secondary/primary pedicels ratio 0–1.4; primary pedicels 5–12, erect to slightly nodding, rarely reflexed; flowers borne singly on primary or secondary pedicels. Basal bract to
3 cm long, shorter than inflorescence. Bracteoles 0.9–2.1 mm long. Tepals equal, 1.6–3.1 mm long, lanceolate, acuminate, entire to crenulate at apex, hyaline to light brown or purple to blackish castaneous brown, with or without hyaline margins. Stamens 6; anthers 0.3–1.1 mm long, shorter or equalling to longer than filaments; anther/filament ratio 0.4–1.8; style 2–14 mm long; stigmas 11–28 mm long, ±persistent. Capsule ovoid, subtruncate to mucronate, equalling to exceeding tepals, stramineous to light brown. Seeds ellipsoid, 1.0–1.6 × 0.9–1.1 mm long, with apical appendages 0.2–1.7 mm long; seed/appendage ratio 0.8–6.0. |

Tepals purple to blackish castaneous brown, without or
with only narrow hyaline margins, mostly 1.6–2.5 mm long;
anther/filament ratio 0.4–0.9; seed appendages usually
0.2–0.9 mm long; seed/appendage ratio 1.4–6.0;
inflorescence compound; often two secondary pedicels on some of the
primary pedicels; secondary/primary pedicels ratio mostly

114b. subsp. atrotepala
|
|
| Geography: |
From C and N Japan to Sakhalin and Kamchatka. A geographically correlated variation has been observed. Many populations from the S part of the species’ range differ in a number of characters and are therefore recognized as a separate subspecies. |
