H o f f m a n n alone seems to have been aware of this not
being the true J. trilobata of Linnaeus, with which it has been
otherwise universally confounded, but which is a smaller
plant, with downy stems, destitute of the long scaly shoots
or radicles so remarkable in ours; neither are its leaves imbricated,
but parallel, nearly square, with three or lour strong
teeth or lobes at the outer edge, or extremity. We cannot detect
its stipulas described by Dillenius.
Our plant, gathered by Mr. Hooker at Tunbridge, and Miss
Hutchins in Ireland, has stems three or four inches long, creeping,
repeatedly branched, smooth, throwing out long simple
cylindrical scaly shoots or radicles, and pinnated throughout
with light bright green leaves, spreading in two directions, of
an unequally ovate oblique form, their rounded, dilated, foremost
edges imbricated over the leaf beyond them, their points
contracted, abrupt, notched with three, rarely four, little
sharp teeth. Betwixt each pair of leaves, on the under side
of the stem, is one small, round, or somewhat kidney-shaped,
crenate, close-pressed stipula. We have never seen any fructification.
Haller says it grows on the extreme branches.
J. trilobata of the Linnsean herbarium is Dillenius’s t. 7 b
f. 22, who having never found the fructification of his plant,
copies as such that of a different species from Micheli, t. 5.
J . 10, and has thus misled Linnaeus and others.
