Nota: Habitu C. paeonifoliae persimilis, differt autem floribus minori- 
bus, calcari minus curvato, cristispermagnis petalorum exteriorum eorumque 
lobulis auriculatis. Ob Patriam etiam species propria suspicanda est. 
Var. Tilingii Fedde, var. nov. 
Cum typo, ut videtur, habitu, foliis et inflorescentia prorsus fere 
congruens. Bracteae inferiores florum valde majores, quasi frondosi, 
ovato-lanceolatae vel ovato-rhomboideae, supra paulatim lanceolatae, in- 
fimae plus quam 1 cm longae. Flores variabili modo effigurati et 
magnitudine variantes, formis transitoriis cum typo conjuncti. In 
exemplaribus a typo maxime aberrantibus flores usque 2,5 em longis, 
petalorum exteriorum cristae minus regulariter parallelogrammoideae, 
sed magis trapezoideae, lobi minus expansi et minus distincte auriculato- 
lobulati, petalorum interiorum ungues ad apicem non quasi stipitati, sed 
paullo angustati in laminam transeuntes, crista dorsali altiore.

— The name of this form of Cerastium which is closely related to C. 
alpinum L. and C. Edmondstonii (Wats.) Murb. et Ostf. (= C. arcticum 
Lange, ex parte) has caused me much trouble. — The characters sepa- 
rating our species (see Fig. 11) from the two others are the following: 
leaves small and short, mostly broadly elliptic or broadly ovate (rarely 
elliptic or elliptic- or ovate-lanceolate), in the sterile shoots close to- 
gether, often imbricate, obtuse; in the flowering shoots few and sepa- 
rated, pair from pair, by long internodes, sometimes more or less acute; 
lower parts of the plant mostly glabrous, upper parts pubescent and 
glandular; bracts with + membranous margins; flowering shoots in the 
more reduced forms one-flowered, in the better developed forms rather 
richly dichotomously branched, but only at the top; flower-stalks 1—2 
times as long as the flower, capillary; sepals 4,5—5,5(—6) mm long, 
broadly ovate, obtuse, with membranous margins and mostly tinged 
with reddish-violet on the outer side; petals about twice as long as
