s i ze OÍS, alpina. Cö/j/a’5-parted; tliesegments narrow, linear,
acute, close-pressed to the corolla: (in S. ö/joiwa they are
nearly double the width and spreading.) Corolla bell-shaped,
narrow and tubular below, gradually widening upwards, but
never expanding like S. alpina; divided or jagged, scarcely
to the middle, into numerous narrow unequal segments.
Stamens 5, inserted in the throat. Filaments flat, slightly
winged on each side below the anthers, extending up their
back and terminating beyond them in a bluntish p o in t: anthers
slightly sagittate at the base, joined by their back to
the filaments, two-celled. Ovarium pyramidal, smooth.
Style long and slender, exserted to some length beyond the
corolla, thickest at the base, slightly tapering towards the
point. Stigma a very small simple head.
We have this Spring had the opportunity of examining
and comparing the whole of the four species belonging to
this genus, and find them all sufficiently distinct from each
other; the present is readily distinguished from S. alpina by
its smaller flower, and long style, which is considerably extended
beyond the corolla, while that of S. alpina is shorter
than the corolla, and included within i t ; we have therefore
not the least doubt but S. montana of Wahlenberg, described
with exserted styles, is in reality the present species, though
referred by Roemer and Schultes to S. alpina, and who, we
suspect, has confused that species with the present, as they
have not noticed i t ; we intend hereafter to publish figures
of the other two species, that their differences may be seen,
and have discarded the name of S. Clusii altogether, as it
only tends to mislead, three of its species having received that
name by different authors : all the species are quite hardy,
are well adapted for small pots or rock-work, and thrive best
in a light sandy soil; they may either be increased by seeds,
or dividing at the root. Our drawing was made from a plant
at the Nursery of Mr. Colvill, who received several of them
from Mr. Schleicher, of Bex, in Switzerland.
The generic name is derived from «roXo?, a round plate or
quoit, and tXXa, a diminution: from its small round leaves,
resembling small flat plates, and the flowers may not be
unaptly compared to that of quoits.
1. Calyx, divested of the Corolla. 2. Corolla spread open, divested of the Stamens.
3. Lower part of the same cut off, to show the insertion of the Stamens, and the form of
the anthers, which are attached by their back to the filaments, that extends beyond them.
4. Ovarium, termmated by the Style, and small capitate Stigma.
