In our last place we nave cne ngure ui a pram, new m --------- - ------ ; . D
Gieseek6 of D ublin; and we have the pleasure of representing another equally interesting novelty m th e fa p a v e r
nudicaule. The smaller specimen here figured was kindly communicated by Professor Gieseck6, gathered by
himself at Achilhead “ scattered in single plants among rocky glens in the hills. I t is in other countries abundant,
especially in the arctic regions of Europe and America. I t adorns the dreary wastes of Spitsbergen, Iceland,
Greenland, and of Melville Island, with its bright and showy yellow blossoms, and the tops of the central range ot
mountains in Norway. I t is likewise found in Eastern Siberia, on the Altaic mountains, m Dahuna, Unalaschka,
and in Labrador: and Dr. Richardson found it on the northern shores of America. H S U
I t is subject to much variation, especially in a cultivated state. In a garden, Siberian specimens have attained
to the height of a foot and a half: but the characteristic marks of the species remain constant. Papaver alpmum,
a native entirely of the Southern Alps, may be known from this by its more delicate habit, in being more glabrous
in all its parts, and by the more divided leaves and their narrower segments. My native specimens of that
variety of P . nudicaule, called & rubro-aurantiacum, are much redder than the specimens figured in Bot. Magazine,
t. 2344.
