JUNCUS. 
“ Stiiin. <i." Aiitli. liuear-obloiig, as long as their filaments. — 
Hoppe figures (i)<. 7H.2.) a plant elosely allied to this but ditfer- 
ing in having (i stain., and filaments nearly twiee as long as their 
elliptieal antli., under the name of J. niyritellus (1). Don) whieh 
it is not ; Don’s plant being most nearly allied to J. lamprocarpus. 
Hoppe’s plant, whieh I possess from the bogs of Cunnaniai-a, is 
perbaps justly referred to J. supinus by Koeh. — Boggy and wet 
places. P. VI. — YIH. 
***** No barren stems. Floioers solitary, remote or corymbose 
and forming a terminal panicle. Seeds not appendaged. 
1!I. J. squarrosus (L.); st. naked simple, 1. linear channeled 
radical, panicle terminal eomjiound with cymose branches, seg- 
ments of perianth ovate-lanceolate acute or rather obtuse as long 
as the obovatc obtuse mucronatc capsule, anth. 4 times as long 
as their filaments. — E. B. St. llfi. 1 1 . — St. erect, 6 — 12 in. 
high. L. numerous, somewhat spreading, rigid, half as long as 
the stem. Caps, pale brown, shining. — Wet heaths and moors.

20. J. compressus ( Jacq.) ; st. with 1 leaf in the middle, 1. linear 
channeled, panicle terminal compound subcymose usually shorter 
than the bract, segments of perianth oval-oblong obtuse shorter 
than the shortly mucronate capsule. — E. B. 934. St. 36. 13. — St. 
slender, erect, round and leafy below, naked and compressed 
above. Floral bracts usually jjale. “ Style half the length of the 
ovary.” Anth. oblong, about as long as the filaments. — Damp 
places. P. VI.— VIII. 
21. J. Gerardi (Lois.); st. with 1 or more leaves, 1. linear 
channeled, panicle terminal compound subcymose usually longer 
than the bract, segments of perianth oval-oblong obtuse about as 
long as the oval-oblong strongly mucronate capsule. — J. cosnosus 
Bich., Sm., E. B. S. 2680. St. 71. 8. — Similar to the preceding. 
St. trigonous in its upper part. Floral bracts usually shining 
brown. “ Style as long as the ovary.” Anth. elongate, at least 
twice as long as the filaments. — Salt marshes. P. VI. — VIII. 
Mud Rush. 
22. J. tenuis (Willd.) ; “ st. above shortly dichotomous pa- 
nicled, 1. lineai-setaceous grooved, fl. solitary appro.ximate mostly 
sessile, cups, nearly spherical shorter than the very acuminated 
leaves of the perianth i” Hooker. — E.B.2174. J. Gesneri Sm. — 
Distinguished from the following by its caj)sule. Smith states 
that the true J. tenuis (Willd., Pui’sh) differs essentially by 
having a cymose not racemose panicle. I am not acquainted 
with the Scottish plant. — “ By a rivulet in marshy ground, 
among the mountains of Clova. Near the summits.” Mr. G.
