and squarrose on main stem, which is 5 - 6 lines wide including 

 leaves, decreasing in size downwards towards base, close and 

 sub-imbricate on branches, conduplicate, lobes united at lower 

 dorsal margin, which is thickened and entire ; dorsal lobe 

 oblique, cordate-acuminate, the base very much produced and 

 rounded semi-orbicular, margin entire ; tip suddenly acuminate, 

 acute ; anterior margin uneven, wavy with minute plaits, both 

 upper margins and tip finely denticulate ; ventral lobe much 

 longer tban dorsal, sub-oblong-trapeziform, apex oblique, ob- 

 tuse, the anterior margin nearly straight ; margins minutely 

 serrulate with a few (2-3) small cilia3 near base ; the apices of 

 the two lobes very divergent. Stipules distant from base of 

 leaves, patent, large, rotund, 1^ lines diameter, retuse ; margins 

 entire, slightly and sparingly ciliate at apex and on the upper 

 sides ; finely and obsoletely waved laterally, with a long thick 

 longitudinal plait in the centre. Cells rather opaque, crowded, 

 oval ; walls thick with minute cellules in the angles. 2-3 small 

 linear segments (phyllodia) on main stem in the axils of the 

 leaves, their margins entire with 2 long hair-like cilise at the tip 

 of each.

Obs. This is another very fine species, pretty closely allied 

 to G. nobilis, Nees, and to G. dichotoma, Col.,* but differing 

 considerably in many characters : as in the great distance be- 

 tween the stem leaves, and their squarrose habit, in the form and 

 serratures of leaves, lobes, stipules, and phyllodia, and in their 

 cells. 



** Leaves without stipules. 



4. G. pltimulosa, sp. nov. 



Plant densely tufted, erect, 1\ inches high ; yellowish-green, 

 becoming light-brown in age ; stems stout, 3 lines wide includ- 

 ing leaves, sub-obovate-linear, leafy to base, simple and forked, 

 sometimes with two short opposite lateral brancblets at tips ; 

 tips nodding, sub-circinnate. Leaves exceedingly thin, very 

 close-set, bifarious, regular, imbricate, spreading, their lobes con- 

 duplicate united at the dorsal margin, the dorsal lobe a little 

 smaller, both lobes overlapping at dorsal and ventral bases, 

 deeply bificl at apex ; apical segments long, laciniate, acuminate ; 

 margins of both lobes largely laciniate-ciliate ; ciliae very long, 

 2-3 branched, acute, and very cellular. Stipules 0. Cells 

 large, very distinct, oval ; their thickish double wails containing 

 numerous minute cellules.
