ZENTARO-TASHIROI Makino, 1910

Distribution : Japan (Honshu, Kyushu), low mountains on the floor of thickets in semi-shade.

 

 

Description (according to IHSP, 2003) :

 

Tufted perennial herbs with creeping or erect to ascending branched stems 5 - 13 cm tall.

 

Leaves in whorls of 4 (-5), alternate in the upper stem parts, linear- to obovate-spatulate, obtuse or obtuse-subretuse or acute, narrowing towards the petiolate base.

 

Inflorescences : Flowering branches to 15 cm, inflorescences few-flowered cymes with 2 - 3 cincinni.

 

FIowers 5-merous, subsessile, sepals unequal, linear-lanceolate, obtuse, petals ovate -lanceolate, shortly acuminate, yellow, widely spreading, filaments yellow, anthers reddish.

 

Cytology : 2n = ±34.

 

Fröderström (1931: 87) included this species in the synonymy of S. lineare, but Ohwi (1965: 497) regarded it as a synonym of S. subtile. According to Ohba (2001: 28), the species differs from S. subtile by the lack of stolons after flowering, narrower and smaller petals, and purplish-red flowering branches with usually ternate leaves.
