MR. F. N. WILLIAMS ON THE GENUS SILENE, 63. 
erectus, laterales adscendentes, pilis crispulis vestiti. Folia 
oblanceolato-spathulata mucronata puberula parce ciliata, basi in 
petiolum attenuata, apice rotundata, superiora angustiora, 
omnia uninervia; bractes lineari-lanceolate acute lanuginoso- 
ciliate. Flores breviter pedicellati. Calyx tubulosus inferne 
haud umbilicatus, fructifer ampliato ovoideus infra capsulam 
vix attenuatus, nervis viridibus superne vend unica conjunctis, 
pilis longis confervoideis patentibus vestitis, inter nervos 
autem scabrido-puberulus, dentibus Janceolatis acuminatis 
albo-marginatis ciliatis. Petala e calyce exserta bipartita lobis 
lineari-oblongis. Filamenta glabra. Capsula ovata subsessilis, 
carpophorum glabrum multies superans.—Valde affinis S. maroc- 
cane, ab e& primo autem dignoscenda calyce fructifero apice 
contracto, preterea differt foliis oblanceolato-spathulatis mucro- 
natis, bracteis lanuginoso-ciliatis, petalorum lobis latioribus, 
carpophoro glabro brevissimo; a S. setaced differt jam primo 
aspectu, calycis nervis confervoideis, etc.

B. Calyx fructifer apice non contractus. 
Of the next species described by Rohrbach (No. 46), which 
is 8. ligulata, Viv., 
Lusus I = S. setacea. 
Lusus 2 = S. sericea a. pubicalycina.

Monogr., p. 105 (S. biappendiculata, Ehrenb.) ; Coss., Illustr. Fl. 
Atlant., fasc. iv. (1890) t. 79 (semina). 
Differt a S. setaced, foliis oblongis vel oblongo-linearibus 
non anguste linearibus, calycis dentibus obtusis, nervis com- 
missuralibus superne latius venulis anastomosantibus reticu- 
latis, petalis purpurascentibus, lobis oblongo-linearibus superne 
latioribus, seminibus majoribus dorso, profundius et angustius 
canaliculatis, canaliculo utrinque marginato, marginibus 
angustis planis vel subundalatis. 
Rohrbach suppressed the name of S. caxopica, misled by the erroneous 
supposition that the specimens from Denderah (Monogr., p. 110), thus 
labelled and distributed by Sieber were authentic, whereas this plant 
of Sieber’s is S. villosa, Forsk., a species which does not occur at or near 
Abotikir, the present name of the ancient Canopus. Ehrenberg’s authentic 
specimens of “ S. biappendiculata,” and Delile’s authentic specimens of
