Caules tenues, atro-purpurascentes. Folia radicalia, glabra, 
obscure viridia. Pedicelli elongati, filiformes, erecti, apice 
inclinati. Calyx 6 mm. (non 10 mm.) longus, striis nigrescen- 
tibus. Petala luteolo-alba. 
Apparently a form intermediate between S. nutans and S. italica with 
subcernuous flowers.

Ceespitosa, multicaulis. Caulis erectus aut interdum obliquus, 
inferne pubescens, et obscure purpurascens, superne glaber et 
Viscosus, geniculatus, inferne usque ad apicem ramosus, ramis 
patentibus dichotomis. Folia subpuberula, inferioria oblan- 
ceolata, vel obovato-spathulata, obtusa vel acuta, non scabra, 
inferne in petiolum longum attenuata, marginatim lanuginoso- 
ciliata, superiora lineari-lanceolata, acuta, sessilia; bractes 
parvee ovate acute albo-marginate ciliate. Flores laxi dicho- 
tome paniculati, ad apices ramulorum terni. Calyx clavatus 
glabriusculus, striis viridibus superne anastomosantibus, 
dentibus ovatis, obtusiusculis, albo-marginatis. Petala supra 
albida, subtus purpurascentia, unguibus exsertis, bipartita 
lobis cuneatis, fauce bicallosa. Capsula ovato-conica, carpo- 
phorum 4-plo superans. Semina parva, reniformia, dorso 
canaliculata, faciebus plana, granulata. 
A S. nutante diversa, magis cespitosa et dichotome ramosa, 
foliis radicalibus non scabris, basi longe lanuginoso-ciliatis, 
floribus plus minus laxis, petalis fauce bicallosis, nec lamellatis.
