The only known species. 
| In spongy bogs. Rare. Bomere Pool, near Shrewsbury, Salop; 
“Wybunbury Bog, Cheshire; Leckby carr, between Thirsk and Don- 
easter, Yorkshire; near Methven, Perth. 
England, Scotland. Perennial. Early Summer. 
Rootstock tough, rather slender, extensively creeping, clothed with 
the decayed bases of the leaves. Leaves narrowly linear, semi- 
cylindrical, with a pore at the apex on the upper side, and with 
dilated sheathing bases, a very small portion of the adnate stipules 
being free at the top of the sheaths. The length of the leaves on the 
barren tufts is 8 inches to 1 foot; those on the flowering stem few, 
alternate, shorter than those of the barren tufts, but the middle ones 
overtopping the raceme. Raceme lax, 4- to 8-flowered. Pedicels at 
first very short, but lengthening in fruit until they are } to 1 inch 
Jong, each pedicel in the axil of a bract resembling the leaves, but 
with a much shorter point. Perianth segments yellowish-green, 
fee strapshaped, recurved, at length shrivelling up until they 
‘are inconspicuous. Filaments rather short ; anthers long and slender, 
yellow. Fruit formed of 3 (or by abortion of 2) divaricate inflated 
vlive-brown broadly ovoid compressed follicles, about the size of sweet- 
pea seeds or a little larger. Seeds 1 (or rarely 2) in each follicle, 
ovoid, pale olive, smooth, about the size of a seed of white mustard.
