MR. F. N. WILLIAMS ON THE GENUS SILENE. 127 
e basi brevissime attenuata vel subrotunda anguste lanceolata, 
longe acuminata, scabrida, margine ciliata; bractese cum 
prophyllis paullum minores angustiores. Flores pauci, pedi- 
cellis, presertim in flore primario, elongatis pubescentibus. 
Calyx clavato-tubulosus rubescens, pubescens, inferne angus- 
tatus et leviter umbilicatus, dentibus ovatis. Petala intense 
rubra, unguibus exsertis, glabris, in auriculas rotundatas 
erosas dilatatis, lamin& obcordaté biloba lobis rotundatis. 
Filamenta glabra. Capsula ovata carpophorum equans. 
A plant with very large flowers, and in thia respect rather resembling a 
species of Eudianthe or Lychnis; but the ovary is trilocular at the base, 
and the dehiscent capsule has six teeth. The petals are nearly 30 mm. 
long, and 12 mm. across at the broadest part of the blade; and the broadly 
auriculate claws distinguish it from most of the annual species of the 
section Dichasiosilene. It may be here observed that the majority of the 
17 species of Silene from Yun-nan, described by Mons. Franchet, should be 
excluded from the genus, as the capsules are not trilocular at the base.
