compact ; clusters 2 — 4 -flowered ; leaflets of the perianth equal ; 

 interior ones with a broad membranous margin at the apex, 

 shorter than the broadly ovate, suddenly acuminated capsule.

Sandy sea-shore near Arklow, where it was first observed by Mr. 

 Hodgens of Dunganstown Nursery. Fl. July. %. — Nearly double 

 the size of the last, rooting deeply into the sand. Scapes erect, 

 straight, simple, round, smooth, leafless, stiff, and very strong, with a 

 sharp rigid point, turned a little aside by the panicle, and rising a little 

 above it. 



# * * Stems leafy. Leaves rounded or subcompressed, and 

 distinctly jointed internally. Panicle terminal. Flowers aggre- 

 gated or fascicled. 



6. J. acutiflorus, Ehrh. Sharp-floioered jointed Rush. 

 Leaves subcompressed ; panicle very compound, pyramidal ; 

 clusters 5 — 6-flowered ; leaflets of the perianth unequal, lan- 

 ceolate, very acute, nearly as long as the narrow, ovate, sub- 

 acuminate capsule. Br. FL 1. p. 161. E. Fl. v. ii. p. 174. 

 E. Bot. t. 2143.— J. articulatus, E. Bot. t. 238. 



Bogs, very common. Fl. June — Aug. %. — One to two feet high* 

 erect. Leaves three to four on a stem, distinctly nodoso-articulate 

 when dry. Panicle diffuse, in fruit spreading. Flowers several to- 

 gether, greenish-brown. General bracteas short, membranaceous, 

 scarcely leafy. Capsules pale-coloured. 



7. J. lampocarpus, Ehrh. Shining-frxiited jointed Rush. 

 Stem ascending, and as well as the leaves compressed ; panicle 

 compound, spreading ; clusters 4 — 6 or 8-flowered ; leaflets of 

 the perianth equal, rather obtuse, shorter than the acute, trique- 

 trous, oblong-lanceolate capsule. Br. Fl. 1. p. 162. E. Fl. v. 

 ii. p. 175. E. Bot. t. 2143. 



Boggy ground and watery places, frequent. Fl. July, Aug. If. — 

 Very similar to the last ; but with large flowers, and deep brown shin- 

 ing capsules. The var. 3- of Hooker, (J. nigritellus, E. Bot. Suppl. 

 t. 3643,) has more numerous flowers in each cluster or head, sharper 

 leaflets to the perianth, pale capsules, and it seems also to unite J. 

 acutiflorus with J. lampocarpus. Hooker. 



8. J. obtusifiorus, Ehrh. Blunt-flowered jointed Rush. Stem 

 and leaves erect, rounded ; panicle very compound, spreading, 

 and divaricated ; clusters 3 — 6-flowered ; leaflets of the perianth 

 equal, rather obtuse, about equal in length with the oval trigo- 

 nous capsule. Br. Fl. 1. p. 162. E. Fl. v. ii. p. 176. E. Bot. 

 t. 2144. 



Boggy grounds, less frequent than the two last. Fl. July. %. — 

 Larger than the preceding. Leaves rigid : heads small. Leaves of 

 the calyx pale-brown. Capsule obovate, light brown. Smith. 



9. J. uliginosus, Sibth. Lesser Bog-jointed Rush. Stem 

 erect, and often swollen at the base, or decumbent and rooting •
