the surface of the ventral lobe into a linear ciliated crest. 
The inflated top of the stem forms the base of the calyx, 
the upper part fixed upon this is formed of two leaves 
united at the base and convoluted above.  Pedicel about 
half an inch long. Capsule oblong, large, splitting into four 
linear valves, which have the seeds mixed with spiral fila- 
ments attached to their bases. 
This rivals in size and resembles in appearance Go£tschea 
Lehmanniana of Nees; from which the absence of stipules 
will at once distinguish it, besides both lobes of the leaves 
being more acuminate and with elongated cilie.

Tufts brownish-olive, about an inch high. The leaves 
meet back to back and, being closely imbricated, present a 
Concave groove along the back of the stem on each side; 
above, the recurved margins are tumid and placed across the 
Stem ; the leaves are mostly entire, a few towards the summit 
ving sometimes but two or three minute denticulations ; 
. 4I texture is close and consists of minute hexangular cells. 
In genera] habit the present bears no inconsiderable resem- 
„ace to Jung. punctata, Tayl., lately found in Ireland and 
in the Canaries, but the subentire and gibbous leaves 
: 1 readily distinguish it.
