JuNCUS triglumis is much more common and plentiful
than the preceding about the little rills and boggy places on
the tops of moft Scottifh and Welch mountains. Mr. Robfon
has even found it in Cumberland, It flowers in July, and is
perennial.
This has very much the herbage and general habit of the
Two-flowered Rufli; but though extremely variable in luxuriance,
it generally confiderably exceeds that fpecies in magnitude.
The number of flowers in the head, though naturally
three, often varies from only one or two, to four or five. In
every cafe, however, the plant is to be known by bearing the
flowers eredt and parallel to each other, not leaning to one
fide, nor one overtopping the other. They are moreover accompanied
by membranous bradteae, fhorter than the flowers
themfelves, inftead of a large eredt leafy involucrum. The
glumes and bradteae are alfo of a fomewhat paler and redder
brown than thofe of the laft.
Dillenius could furely never have feen this Rufh when, in
his edition of Ray’s SynopJis% he fuppofed it the fame with
Scirpus cafpitofus; nor was Mr. Hudfon’s conjedture more
happy, when, in his xft edition, ‘he took the plant of Ray fof
the Schoenus ferrugineus of Linnaeus,
