Species nos. 91–110 belong to an informal group that approximates to Silene sect. Cucubaloideae Edgeworth & J. D. Hooker. As circumscribed here, this is a distinct, probably monophyletic group characterized by more or less creeping habit and fleshy, fasciculate root tubers.

The species of the “Cucubaloideae” group can be described as follows. Herbs perennial, with clustered, tuberous roots. Stems diffuse, supine or ascending, branched. Inflorescence a dichasial cyme. Flowers bisexual, erect. Calyx tubular-clavate or campanulate, appressed to capsule in fruit, 10-veined, veins usually violet, usually coherent at calyx teeth. Androgynophore short. Petals red, rarely white, bifid, sometimes 1-toothed on each side; coronal scales present. Styles 3. The group is distributed in China, the Himalayas, and Indo-China.
