In alpine rivulets. 



About the summits of the Scottish and Wel^h mountains. At 

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

 On Ben Lomond near the top, in great plenty. 



Perennial. Juhj. 



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

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

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

 Leaves chiefly radical, much like those of J. biglumis. Head 

 usually of 3 flowers, 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. Calyx-leaves equal, elliptic-oblong, keeled, 

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

 still longer, rounded at the summit, chesnut-coloured. Seeds 

 oval, with a membranous lateral tu7iic, extended in a point be- 

 yond each end, as in the foregoing. 



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

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

 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 calyx.
