In alpine rivulets. 



About the summits of the Scottish and Welsh mountains. At 

 Borrodale, near Keswick, Cumberland ; Mr. Robson. ffith. 

 On Ben Lomond near the top, in great plenty. 



Perennial. July. 



Like the last in habit, but twice as large. Roots somewhat creep- 

 ing. Stems solitary, from 3 to 6 inches high, round, smooth, 

 naked, except one or two long-sheathed Uares, near the base. 

 Leaves chiefly radical, much" like tiiose of J. biglumis. Head 

 usuallv of 3f<jiceTs, all erect and on a level, sometimes of 2, or 

 4, subtended by a pair of nearly equal, elliptical or ovate, spread- 

 ing, brown, membranous bracteas, one of them very rarely tipped 

 with a small leafy point : there is besides frequently a smaller 

 interior bractea.' Calyz-leaves equal, elliptic-oblong, keeled, 

 membranous at the edges. Stam. longer than the calyx. Caps. 

 still lonarer, rounded at the summit, chesnut-colour«l S^ds 

 oral, with a membranous lateral tunic, extended in a point be- 

 vond each end, as in the foregoing. 



Mr. Bicheno justly describes the leaves as internally cdlnlar, but 

 there is nothing of partitions, or articulations, to be discetned 

 externally. 



19. J. castaneus. Clustered Alpine Rush. 



Stem unbranched, leafy. Leaves keeled, flat: sheathing 

 at the base. Heads' terminal, mostly in pairs, many- 

 flowered, with leafy bracteas. Capsule twice the length 

 of the calvx.
