XCVII. JUNCACEiE. 
\Juncus. 
Salt marshes in various parts of England, but not frequent. St, 
Andrew’s ; banks of the Clyde ; Arran ; coast of Ayrshire ; Scotland. 
Kingstown and other places in Ireland. Tf.. 7, 8. — In this and the 
following the outer bractea, or portion that rises above the panicle, 
is broad and membranous at tbe base, and less like a continuation of 
the scape than in tbe species of the preceding division. 
G. J. acutus L. (great sharp Sea It.) ; barren scapes and 
outer bracteas pungent, panicle very compound mostly compact, 
clusters 2' — 4-flowered, sepals equal about half as long as the 
broadly ovate suddenly acuminate capsule, interior 3 with a 
broad membranous border at the apex. JE. B. t. 1614. 
Sandy sea-shores, principally on the south and west of England and 
Wales. Norfolk. Wicklow and Arklow, Ireland. 7L. 7. — Larger 
and stouter than the last, especially the capsules, which are of con- 
siderable size, much protruded, rich brown and glossy. 
*** Stems leafy. Leaves terete or subcompressed, and usually dis- 
tinctly jointed internally. Panicle terminal. Flowers aggregate 
or fascicled. Seeds without an appendage at the ends. 
7. J. acutfldrus Ehrh. (sharp-flowered jointed R.)\ stem and 
leaves subcompressed, panicle very compound pyramidal, clus- 
ters 5 — 6-flowered, sepals unequal lanceolate very acute nearly 
as long as the narrow ovate subacuminate (pale brown) cap- 
sule. Sm. in E. B. t. 2143 (ad calc.). J. articulatus L. : 
E. B. t. 238. 
Bogs, very common. 11. 6 — 8. — Stem 1 — 2 feet high, erect. 
Leaves 3 — 4 on a stem, distinctly nodoso-articulate when dry. Panicle 
diffuse, in fruit spreading. Flowers several together, greenish brown. 
General bracteas short, membranous, scarcely leafy. Capsules pale- 
coloured. 
8. J. nigritellus D. Don (black-headed jointed R.) ; stem 
and leaves somewhat terete, panicle slightly compound erect, 
sepals acute shorter than the linear-oblong trigonous rostrate 
(nearly black) capsule, interior 3 rather longer and broader. 
E. B. S. t. 2643. 
Marshy spots on the mountains of Clova, Forfarshire. 2£. 7, 8. 
— Similar to the next, but the sepals are all decidedly acute. Capsule 
at length black and glossy, larger and more suddenly pointed than in 
J. lamprocarpus, of which however we incline to think it only a variety. 
Indeed it is probable that both, along with J. uliginosus, ought to be 
united to J. acutiflorus, being chiefly distinguished from it by the 
outer sepals being acute. 
9. J. lamprocarpus Ehrh. (shilling-fruited jointed R.) ; stem 
ascending and as well as the leaves compressed, panicle re- 
peatedly compound erect or somewhat spreading, clusters 4 —
