320 Mr. J. E. BiCHENo's Observations 



outer ones largest, not longer than the flowers, and opening so 

 as to let them stand all on the same plane. Calyx-leaflets lan- 

 ceolate, equal, blush-coloured at the tips. Style very short. 

 Capsule elliptical, mucronate, somewhat obtuse, three-sided, 

 scarcely exceeding the calyx. Coruncula elongated at each end 

 of the seed. 



This is not so rare a plant with us as the /. biglumis, being found 

 in the mountainous districts of Wales and of the North of En- 

 gland, as well as in Scotland. I have met with it on Helvellyn, 

 on Fairfield, and most of the other mountains about Ambleside, 

 and at the edge of Scales Tarn in Saddleback. Dillenius mistook 

 it for a variety of Scirpus ccespitosiis. The leaves instead of being 

 flat, as described in the speci6c char^^jj^ every botanical au- 

 thor but Haller, Wahlenburg, and Browh, are constructed with 

 cells in a similar manner to those of J. uUginosus ; and the articu- 

 lations are much more susceptible to the touch on drawing a leaf 

 between the thunHSand fin ger:— -" Semper tarn angusta et tereti-
