Matlock, October, 1833.
Stems from 2 to 4 inches long or more, branched and
tufted, sometimes bent upwards like Leucodon sciuroides,
but more frequently in loose soft tufts of a pale yellowish
green colour. Leaves linear-lanceolate, very long, rather
flaccid, wavy or flexuose, entire, nerved nearly to the summit,
widely spreading and some what recurved, variously bent
when dry, but not crisped, frequently beset on the surface
and at the margin with small gland-like bodies, which may

to become gemmiparous. Fruit-stalks very short.
Capsules scarcely emerging from the foliage, narrowly ovate,
with eight ribs or furrows, gradually tapering below into the
