126 MR. F. N. WILLIAMS ON THE GENUS SILENE. 
Adde syn. S. Dilleniana, Schott, in Desf. Cat. Hort. Paris. 
ed. III. p. 264 (vide Rohrb., Monogr., p. 228, uti sp. dubia). 
Ex syn. 8. tenuiflora, Guss. (species propria). 
In a few floras this species is described as having nerves anastomosing on 
the calyx, but in all the authentic specimens I have examined, the ten 
simple prominent nerves have been quite free from any secondary or con- 
necting strie: this is the more easy to demonstrate, since the surface of 
the calyx is quite glabrous. 
This polymorphous species is generally distributed through almost the 
whole of the Mediterranean region, and from thence into the warmer parts 
of Central Europe: being sometimes introduced with flax, it has become 
naturalized elsewhere, as almost to appear indigenous.

Hee species pulchra ex cl. Heldreichii observationibus et ex 
speciminibus fructiferis, calyce fructifero apice contracto 
gaudet ideo non inter Seriem 8 — Atocia — sed juxta S. 
antirrhinam militat: vide Oesterr. Bot. Zeitschrift, 1878, p. 29. 
Ergo planta iterum hic descripta est. 
Caulis erectus superne vel e basi paullum ramosus, glaberri- 
mus superne viscidus. Folia inferiora rosulata, obovato- 
spathulata, obtusissima, hirtello-puberula, ciliolata, superiora 
lanceolata vel lineari-lanceolata, acuta; bractese cum prophyllis 
parve acute ciliate. Pedunculi tenues calyce multo longiores. 
Calyx cylindrico-clavatus, rubellus, basi attenuatus, subumbili- 
catus, nervis saturatius rubellis prominentibus, dentibus ovatis, 
acuminatis, late albo-marginatis. Petala purpurea, unguibus 
exsertis, lamina oblongé integra vel vix emarginata, appen- 
dicibus binis elongatis, lanceolatis. Capsula_ ovali-oblonga, 
carpophorum equans. Semina tuberculata, dorso convexa, 
faciebus planiuscula.
