G a t h e r e d in marshes at Limpenhoe, Norfolk, by the
Rev. G. R. Leathes, in August last. It is less common than
J , lampocarpus of acutiforus, and flowers later.
This is easily distinguished by its pale, entangled, much-
branched panicles, whose ultimate branches are strongly reflexed.
The stem is internally jointed as well as the leaves,
and, as the Rev. Mr. Davies observes, never bears more than
two leaves, notwithstanding its tallness. These are not compressed.
Calyx-leaves all obtuse and elliptical, with a broad
membranous edge. Capsule scarcely extending beyond them,
light brown, shining.
We have this rush from Switzerland, and Haller certainly
confounded it under his n. 1323 along with our acutiforus, as
did Dillenius by inserting Doody’s plant under n. 9 in his edition
of Ray’s Synopsis, 433. See Mr. Davies’s accurate
paper in the 10th volume of the Linnaean Society’s Transactions.
