8-flowered, sepals equal shorter than the acute triquetrous 
oblong-lanceolate (dark brown) capsule, outer 3 acute, inner 
ones obtuse. E. B. t. 2143.

dark brown and shining.

10. J. uligindsus Sibth. ( lesser Bog jointed R.) ; stem erect 
and often swollen at the base or decumbent and rooting, leaves 
setaceous slightly grooved faintly jointed internally, panicle 
nearly simple irregular, clusters few- or many-flowered, sepals 
equal oblong nearly as long as the elliptical very obtuse mucro- 
nate (pale brown) capsule, outer 3 acute, inner ones rather 
obtuse. E. B. t. 801. J. bulbosus L. Sp. PL ed. 1. J. sub- 
verticillatus Will/. J. supinus Mcench. 
Boggy and swampy places, and often partly floating in shallow 
water. If.. 6 — 8. — A highly variable plant, depending much for 
its appearance on soil and situation. In rather dry places the stem is 
often erect, with a swollen base (.7. bulbosus L.), but sometimes the stems 
are spreading or procumbent (J. subverticillatus Wulf.); again, these 
procumbent stems often take root, or, when growing in water, they 
float and spread their long flaccid branches in all directions. 
11. J. obtusijlorus Elirh. (blunt- flowered jointed R.) ; stem 
and leaves erect terete, panicle very compound spreading and 
divaricate, clusters 3— 6-flowered, sepals equal all obtuse about 
equal in length with the ovate-acute trigonous (pale brown) 
capsule. E. B. t. 2144. 
Wet pastures and marshes, not unfrequent. If. 8. 
**** Stems leafy. Leaves plane or grooved above , not distinctly jointed. 
t Seeds with an appendage at each end. 
12. J. castuneus Sm. (clustered Alpine R.) ; stem terete 
2 — 3-leaved, leaves hollow semicylindrical grooved above, heads 
of flowers terminal generally single sessile or peduncled shorter 
than the bractea, capsules ovate-oblong pointed bluntly trigonal 
nearly twice as long as the elliptic-lanceolate acute sepals. 
E. B. t. 900. 
Rare. Elevated mountains of Breadalbane ; rocks at the head of 
Glen Callader, in Braemar. In the county of Durham ?. If. 7,8. — 
“ Stem hollow. Leaves with the channelled side very thin and mem- 
branous, and within are found distant transverse partitions. Upper 
part of the leaf rounded and compressed. Sepals 3 -ribbed. Style 
breaking off at ajoint. Capsule shining, and as well as the perianth 
and inner bractea of a deep chocolate colour.” — W. Wilson. 
13. J. trifidus L. (three-leaved R.)'; stem 1-leafed, sheaths
