exilis, Col., and P. distans, Col.,"'' but differs in its entire peri- 

 gonial leaves, &c., and also to P. polystachija, Col. (infra). 

 The male spike resembles that of P. hranniana, Nees. 



II. Sometimes 3-4 male spikes are found adnate on a 

 single main stem, beginning at a little distance from the 

 base, and so on from each other, with a few pairs of small 

 leaves between them. A very graceful little species. 



9. P. folystachya, sp. nov. 



Ehizome creeping, long, much-branched. Plant erect, 

 dendroid, stiff, Sin. high ; main stem woody, simple, 3|^ lines 

 wade, leafy to base, dark-brown, branched above ; branches 

 fevr, long, slender, spreading, alternately and equidistantly 

 spiked, 4-6 on a branch, the leaves between them small. 

 Leaves green, close, imbricate at bases, regular, patent, sub- 

 deltoid, apex broad, rounded and truncate, with a few (4-5) 

 short teeth, and 2-3 longer and more acute at anterior ventral 

 base, sometimes 1-3 distant and minute ones on ventral 

 lateral margin, which is overlapping; dorsal margin very 

 oblique, straight, entire, largely decurrent ; both margins 

 wavy and recurved. Cells small, densely crowded, orbicular, 

 each surrounded by a chain of very minute and clear cellules. 

 Male spikes sub-lanceolate, 3-2 lines long, deeply sulcate on 

 dorsal surface, turgid on ventral, brownish-yellow, lower ones 

 9-10 jugate, gradually decreasing in size (6-4 jugate) to top, 

 a,nd so their intermediate leaves ; also, sometimes five together 

 are fascicled at apex. Perigonial leaves rather large, tips 

 recurved, sharply acute, and 2-3-toothed.

 1888 : W. C. 



Obs. A species having affinity with P. spenceriana (supra), 

 but differing in its larger and more robust size, in habit, in 

 shape of leaves, and in the apices of the perigonial leaves 

 being toothed. 



10. P. suhjiahcllata, sp. nov. 



Ehizome creeping, main stems erect, dendroid, wiry, stiff, 

 woody, leafy to base, l|^in.-2in. high, 3 lines wide, including 

 leaves, but narrower at base and on branches ; bipinnately 

 branched at top ; branches few, regular, spreading nearlv at 

 right angles, graceful, almost sub-flabellate. Leaves very thin, 

 pellucid, lively green, rather distant, not imbricate (young 

 stem-leaves sub-imbricate), patent, 1^ lines long, sub-trapezi- 

 form (in outline), decurrent across stem ; apex blunt, rounded; 

 base sub-amplexicaul, wavy with a central hollow, convex, 

 margins recurved ; ventral and apical margins cilio-serrate.
