Dense cespitosa, glabra vel inferne brevissime retrorsum 
scabridula, superne haud viscida. Caules filiformes erecti, vel 
e basi arcuata, geniculate-adscendentes, foliosi, ramos, ramis 
tenuissimis erectis bracteatis unifloris. Folia elevatim

pallida, coriaced, dilataté, margine ciliato-aspera. Flores 
solitarii, pedunculis calyce longioribus vel subsequantibus 
filiformibus. Calyx tubuloso-clavatus umbilicatus glaber, 
pallido-purpurascens, dentibus ovatis, membranaceo-marginatis, 
ciliolatis. Petala luteo-virescentia, bipartita, lobis lineari- 
oblongis, appendicibus binis parvis triangularibus, unguibus 
glabris, superne dilatatis. Capsula ellipsoidea, carpophoro 
sublongior inclusa. 
A precedenti distinguitur caule haud viscido et capsula 
inclusa.

Bertoloni and Rohrbach have confused this plant with S. Notarisii of 
Cesati, which is only a local form of S. Saxifraga. Rohrbach also mentions 
the absence in this species of anastomosing nerves in the calyx, and that 
the teeth are alternately acute and obtuse; but an examination of authentic 
specimens shows that the nerves of the calyx do not anastomose, and 
the teeth seem to be all acute, with occasional variations. For this reason 
I have transferred the species to another group, and reduced S. clavata 
(n. 117) to a variety of it. It is quite possible that the teeth of the 
calyx in the preceding species may be found to be only an occasional 
variation, and that they are either all acute or all obtuse ; if so, there is n° 
necessity for continuing to keep S. fruticulosa distinct and in a separate 
group.
