52 Transactions. — Botany. 



teeth 14-16, irregular, rather distant, filled with minute cells ; 

 sinuses large, rounded, semicircular, the base much arched and 

 overlapping stem ; dorsal margins straight, entire, thickened, 

 with rarely 1-2 very minute blunt (budding?) teeth on 

 upper margin. Involucral leaves at tips of branches erect, 

 broader and more largely ciliate. Cells crowded, of 2-3 kinds 

 — (1) orbicular and clear, with minute cellules betw^een them ; 

 and (2) beaded with black dot-like centres, these last mostly 

 marginal.

11. P. alpina, sp. nov. 



Plant sub-dendroid, 2in.-2^in. high, 2 lines wide ; stems 

 sub-succulent, 3-pinnately branched above ; branches irregu- 

 lar, leafy, pale-green young, dark-coloured in age. Leaves 

 sub-vertical, distant and smaller on main stem, sub-imbricate 

 on branches, rotund, 1 line diameter, slightly dimidiate, set 

 obliquely, contracted at base, slightly amplexicaul, much de- 

 current, concave and slightly plaited, toothed ; teeth irregular, 

 mostly alternately long and short, margins of both anterior 

 and posterior bases entire. Cells compact, sub- orbicular, their 

 walls thick and dark, with minute cellules in them.

12. P. henjgreniana, sp. nov. 



Plant largely tufted, sub-erect, densely ovei'growing. 

 Stems lin.-3in. long, 2^ lines wide, light-brown, leafy to base, 

 simple, forked and branched irregularly above ; a sub-fiagel- 

 late branch usually springs from base of perianth. Leaves 

 light-green : those on main stem sub-opposite, regular, close 

 not imbricate, spreading, sub-obovate-reniform, dimidiate, 

 narrowest at base ; tip obtuse and (with anterior margin) dis- 

 tantly toothed ; posterior margin entire, straight and slightly 

 curved, slightly decurrent : those on branches smaller and 

 more distant, with fewer (3-4) teeth at apex. Involucral 

 leaves similar to those on main stem, broader, erect, more 

 toothed. Cells rather large, compact, obscure, oval and sub- 

 orbicular, with minute interstitial ones. Perianth terminal 

 and axillary between two divergent branches, obovate, mouth 

 small, slightly and irregularly toothed, two of the teeth rather 

 long and coarse. Fruit-stalk short, scarcely exserted. Cap- 

 sule brown ; valves oblong-lanceolate, sub-acute.
