88 MR. F. N. WILLIAMS ON THE GENUS SILENE. 
133. Sinene pyomma, Adams, in Weber et Mohr, Beitr., 
i. (1805) p. 59; Rohrb., Monogr., nu. 2, p. 78. 
Caules sive rami florigeri adscendentes dense pubescentes. 
Folia radicalia rosulata, obovato-spathulata, mutica, in petiolum 
longum attenuata, pubescentia, ciliata ; caulina minora elliptica, 
obtusa, in petiolum brevem attenuata; bractew et prophylla 
parve albo-marginate ciliate. Flores in dichasio paucifloro 
brevissime pedicellati, odoratissimi. Calyx anguste cylindricus 
evenius sanguineus vel pallidus, fructifer vix ampliatus infra 
capsulam constrictus, basi truncata leviter umbilicatus puber- 
ulus, dentibus obtusis albo-marginatis dense lanuginoso-ciliatis. 
Petala rosea, unguibus glabris, bipartita lobis oblongis, appen- 
dicibus binis magnis ovatis. Filamenta glabra. Capsula ovata 
carpophorum pubescens fere bis superans. Semina reniforma 
compressa, dorso canaliculata, margine rotundata, pluriserialiter 
cristato-echinulata, faciebus curvato-excavata. 
Authentic specimens of this plant are seldom found in herbaria; descrip- 
tions of the species vary, and appear to be based upon the examination of 
imperfect material. In this case the description has been drawn up from 
specimens collected in the locus classicus by Ruprecht, and authenticated 
by him in Herb. Mus. Brit., with notes on his observations on the living 
plant in his ‘ Fl. Caucasi.’ Apparently this plant is wrongly placed in the 
subgenus Gastrosilene by Rohrbach. The calyx is not inflated, and is 
without anastomosing nerves : this is easily demonstrated in the specimens 
preserved in Herb. Kew and Herb. Mus. Brit., and the Kew specimens 
certainly seem to be authentic, as they are verified by Ruprecht and 
labelled “Mus. Bot. Acad. Petrop.” Further, nothing is said in the 
original description as to the presence of anastomosing nerves on the surface 
of the calyx. 
Hab. In alpine districts of the Western Caucasus, in the 
prov. of Trans-Caucasia.

p- 176 (1895). 
Glabra, 50 centim. alt. Caules adscendentes, ramulis 1-2- 
floris. Folia lineari-lanceolata, acuminata, glabra; bractew 
lanceolate, acutissime. Calyx elongato-infundibuliformis, 
3 centim. longus, basi truncatus, glaber, dentibus semi-ovatis 
albo-marginatis, exterioribus acuminatis. Petala alba vel 
rosacea, subtus bruneo-venosa. Capsula oblonga, carpophoro 
bis terve superata.
