Genus 67. Hypopterygium, Bridel. 

 1. H. hillii, sp. uov. 



Plant closely c^spitose iu small tufts. Stems about ^ inch 

 high, thickly tomentose throughout with dark brown tomentum. 

 Frond sub-deltoid-orbicular, pale yellowish-green, 5-6 lines 

 broad, the lower branches 2-pinnate, the upper simple. Leaves : 

 on the stem, deltoid-acuminate, nerveless, margins entire slightly 

 uneven, cells long and narrow; on the primary branches, dis- 

 tichous, spreading, close and slightly imbricate, broadly ovate, 

 much apiculate, dimidiate, very thin almost pellucid, stoutly 

 margined ; margins serrate ; nerve extending about three-fourths 

 of leaf ; cells small and sub-orbicular at tips, larger and oblong 

 at centre and base with minute interstitial cellules ; dorsal leaves 

 orbicular, very largely apiculate, the mucro stout and acute and 

 nearly half the length of the leaf, margined, slightly denticulate 

 near apex ; nerve stout, extending beyond middle ; cells as in 

 those of the primary branches ; perichsetial narrow-ovate, much 

 acuminate, acute ; cells very long and nairow. Fruit-stalk, 

 5-7 to each plant, about i inch long, reddish, erect, tip slightly 

 curved. Capsule a little drooping, oblong, red, minutely and 

 regularly papillose, broadest and tubercled near base ; cells 

 large, sub-orbicular-quadrate ; outer teeth dark-brown, subulate, 

 acummate, with no median line but a dark line at margins, 

 transversely sulcate ; the inner teeth nearly as long as the 

 outer, pale, subulate, acuminate, bifid, tips almost capillary,

Obs. This elegant little fern-like moss is allied to the smaller 

 species of Hypopterygium, (" Sec. I. a. Leaves not mixed with 

 bristles ; ** branches 2-pinnate;") of which we have some half- 

 dozen or more known and described species, but it is very 

 different from them all. I have, with much pleasure, named it 

 after its discoverer, Mr. Henry Hill, B.A., Inspector of Govern- 

 ment Schools for the Hawke's Bay District, whose ready zeal and 

 care in collecting, and kindness and liberality in imparting 

 botanical specimens of rare plants, I have long thankfully expe- 

 rienced, as my published botanical papers will abundantly 

 testify. 



2. H. pachyneuron, sp. nov. 



Plant, rhizome stoutish, creeping, 2-3 inches long, brown, 

 slightly hairy. Stems single, distant on rhizome, erect, 1 inch 

 high, rather slender, glabrous, leafy and green above, bare and
