Silene incisa C. L. Tang

It is difficult to find consistent and non-overlapping differences between this species and Silene dawoensis . The petal lobes of the type specimen of S. incisa are slightly crumpled or undulate along the margin, but otherwise similar to those of S. dawoensis, and hardly incised.

Herbs perennial, 30--60 cm tall. Roots robust, lignified. Stems sparsely caespitose, suberect, slender, glabrous, apically viscid. Basal leaves oblanceolate, withered at anthesis, 5--8 cm × 5--10(--12) mm, both surfaces glabrous, slightly coarse, margin sometimes ciliate, midvein prominent, base attenuate into long petiole. Cauline leaves with short sterile axillary branches, gradually smaller than basal leaves. Flowers 2(--2.5) cm in diam., erect, in a lax, few-flowered thyrse; cymules with peduncles shorter than or subequaling pedicels, opposite, 1--3-flowered. Pedicel 1--2.5(--3) cm, slender, glabrous or sparsely and shortly hairy, viscid; bracts linear or linear-lanceolate, ciliate. Calyx tubular, ca. 30 × 3 mm, glabrous, clavate in fruit, longitudinal veins green or violet, teeth 1--2 mm. Androgynophore ca. 2 cm, glabrous. Petal claws cuneate-oblanceolate, glabrous, auricles not obvious, limbs exserted beyond calyx, pale red, triangular-oblanceolate, 1--1.5 cm, divided to about halfway, lobes band-shaped, uneven; coronal scales papillate. Stamens and styles exserted; filaments glabrous. Styles 3. Capsule globose-ovoid, 1--1.2 cm, shorter than calyx, rarely subequaling calyx. Seeds reddish brown, globose-reniform, ca. 1.5 mm. Fl. Jul--Sep, fr. Sep--Oct.
