C o m m UNI CAT ED by Mr. Turner, and Mr. G. Don ; as
well as by Dr. Wood from Dublin. It is said to be found on
shady parts of many Scottish and Irish mountains.
The stems grow in dense tufts, several inches broad, and are
very slender, from two to five inches high, simple or somewhat
branched, clothed, more or less closely, with four rows of small,
pale olive, sickle-shaped leaves, cloven above half-way down
into two linear-lanceolate, equal, acute, entire segments. The
edges of the leaves are entire ; their substance strongly reticulated
; and there are no stipulas or scales at their base. The
sheaths are terminal, solitary, enveloped in leaves, bell-shaped,
cut half-way down into several segments like those of the foliage.
Fruitstalk short. Capsule brown, dividing into four
ovate recurved valves, which soon split irregularly into more.
Our fructification is taken from a specimen, gathered by
Mr. Menzies, at Banks’s isles, on the west coast of North America,
which exactly agrees with the British ones, and revives
slowly in water; in which respect Mr. Hooker says our plant
differs from the West Indian J. juniperina of Swartz; still he
judged it best to consider them as varieties of one species.
