I have here the satisfaction of presenting to the lover of British botany an entirely new and most elegant species
of Primula, which, though it has been for some years known in gardens by the name which is aboveBgiven to it
yet was not supposed to possess any essential characters distinct from P . farinosa, until it was lately examined at
die Botanic Garden of Edinburgh. This point was satisfactorily ascertained by my friends Dr. Graham the
Professor of Botany at that University, Mr. Greville, and myself.
Although doubtlessly very closely allied to Primula farinosa, yet there is something in the very habit of the
present plant, independently of its colour, which enables the horticulturist to distinguish it at once, and even by
the foliage merely. Tbe leaves of Primula scotica are more farinose, and edged with much closer and smaller
teeth. The scape is shorter and thicker, as are also the pedicels; and these, as well as the large, broadly ovate and
inflated calyces, and the tube of the corolla, are far more mealy. The colours of the two plants also afford excellent
marks of distinction. In P . scotica the tube is scarcely incrassated upwards; the limb is cut into shortly and
broadly obcordate, closely set, dark violet-purple segments; tbe mouth of the tube is furnished with five distinct
emarginate glands, which are extremely apparent even to the naked eye. In P . farinosa, on the contrary, the
tube is evidently swollen immediately below the limb; the limb itself has five segments obcordate at the extremity
but much attenuated at the base, which stand apart from each other, and are of a purplish rose-colour; theinouth
has indeed, though not hitherto noticed by any author, glandular processes, but they are by no means formed into
five distinct portions. The situation of the stamens in the two flowers is also different; in P . farinosa they are
placed at the very mouth of the tube, so that the tips of the anthers are a little exserted; in P . scotica they are
quite included within the tube, so as to be only visible by looking directly down into it. The pistil, in which I had
the least expected it, affords a mark o f distinction; for whereas the germen is broadly obovate and the stigma truly
capitate m the Bird’s-eye Primrose, in the subject of the present plate the germen is round and the stioma is
hvedobed. &
To these differences, which I have found to be quite constant in a great number of living specimens which I
have examined, it may also be added that the flowers appear a month later, being in perfection, even in gardens
in the month of July, when those of the other species are entirely gone. The flowers bear also a much greater resemblance
to those o f P . Auricula than of P . farinosa. °
The only botanist who has been so fortunate as to discover this beautiful plant is Mr. Gibb of Inverness who
also first detected the Ajuga pyramidalis. The habitats which he has been so kind as to give me for it are Holborn
Bead, near Thurso in Caithness, where it is very abundant, and also that part of the country which is crossed in
going from Thurso to Dunbeath..
With the view to establish this species more certainly by contrasting it with Primula farinosa, and also to make
tneir points of difference more clearly understood, I have given figures o f the flowers of both upon the same plate ■
ana as the specific character of the latter will now need correction, I would propose the following:
P . farinosa; foliis obovato-lanceolatis farinosis crenulatis, calyce oblongo-ovato, cor,oil® limbo piano, fauce
vix glandulosa, segmentis obcordatis basi attenuatis distantibus.
n S l l l l of S $ «pecie» in 01d Series of FI. Lond. is excellent: in that however in Svensk Botanih
the colour of the corolla and the shape of the segments are the same as in our P . scotica; but as there
a-e no dissections of the flowers, I am not prepared to say to which species it may belong.
