MR. F. N. WILLIAMS ON THE GENUS SILENE. 45 
In all the specimens I have examined at Herb. Kew. and Herb. Mus. 
Brit., the leaves are acuminate and lanceolate rather than oblong-lanceolate, 
as stated by Rohrbach, and the midrib is prominent, and the two lateral 
nerves very faint: in the variety the three nerves are distinct, and the 
midrib is not more prominent than the lateral nerves. 
Geogr. limits—N. Along the R. Irtysch, near Semipalatinsk, 
Siberia. 
S. Desert of Soungaria, Central Asia. 
LE. Coast of Okhotzk, Siberia (var. 8). 
W. Banks of the R. Moskw4, in Central 
Russia (Clerc, ex Nym., Consp. Fl. Eur.,

Caules cespitosi simplices triarticulati glabri. Folia cum 
bracteis linearia obtusa ciliata, basin versus attenuata. Flores 
solitarii graciliter pedicellati. Calyx oblongo-campanulatus 
umbilicatus, pubescens pilis patentibus mollibus longis, eglan- 
dulosus, membranaceus, viridis totus et viridi violaceus, fructifer 
ellipsoideus ore late apertus 18-22 mm. longus; tenuissime 
reticuloso-venosus, nervis tenuibus commissuralibus subobso- 
letis; lobis ovatis obtusis rotundatis ciliolatis. Petala indivisa, 
Unguibus inclusis, appendicibus setaceis. Capsula ovato- 
cylindrica subsessilis carpophoro glaberrimo. Semina dorso 
obtuse canaliculata, faciebus plana marginata, levia. 
This plant has been shifted about from one genus to another, chiefly on 
a of the presumed absence of commissural nerves. It would be very 
Convenient to include it in Saponaria owing to its 3-styled ovary. 
© Nervation of the calyx is at best very faint and indistinct, but the 
oo of commissural nerves at the base, especially on the inner 
the indivi demonstrable, and quite as apparent as the interlacing of 
ibe ni ual nerves, Taking into consideration its general habit and 
ta whi iracters, it is therefore reasonable to refer the species to the genus 
e1 1t was placed by Wulfen. The species is usually included in the 
pel Italian floras, but all the localities given are now in Austrian
