Colenso. — Description of new Cryptogamic Plants. 235 



smooth, with numerous small orbicular cells, margins entire ; 

 operculum long, semi-conical, acute, beak very long, slender, 

 straight. Calyptra large, broadly conical, obtuse, J^th inch 

 long, whitish, upper half thickly tubercled (or sub-echinate) ; 

 tubercles irregular, long, blunt ; laciniate and much fimbriate 

 below ; fimbriae ragged, branched, spreading, obtuse, recurved. 

 Monoecious ; paraphyses numerous near bases of fruit-stalks ; 

 antheridia axillary near capsules, each linear sac clavate, con- 

 taining a red globular spot near apex. 



Hab. On stones in the bottoms of narrow deep watercourses ; 

 dark shaded woods near Norsewood, County of Waipawa ; 1884-5 : 

 W.C. 



Obs. I. A very fine species, certainly approaching very near 

 to H. cristata, Arn. ; but, after long and repeated examination, 

 I cannot but deem it to be distinct. It also has some affinity 

 with H. lophophora, Col. (" Trans. N.Z. Inst.," vol. xvii., p 

 260). It differs, however, from H. cristata in size, habit, and 

 form of stems and leaves, and in their colour, and in the form 

 of its capsule, which is also sub-apophysate and tubercled 

 [vide Hedwig, Sp. Muse, t. 49) ; in form and size of apex of leaf 

 and apical cells (vide Schwg. Suppt.. tab. cexxviii., figs. a. b.) ; 

 in its large and broad sub-tuberculous calyptra, laciniated at 

 base ; and in the short, thick, patent hairs on its seta and crest ; 

 and also in its peculiar habitat or place and manner of growth. 



II. I have only met with this moss in deep, dark gullies, 

 where it must be nearly always submerged ; it clings strongly 

 by its roots to pebbles in the soil, so that the support comes 

 away with the plant in collecting ; it bears fruit in June and 

 July. Plants that I brought away living have flourished three 

 to four months in a tumbler of water, in which they are mostly 

 kept submerged. 



12. H . pygmaa, sp. nov. 



Small, tufted. Stems erect, 4-6 lines high, glossy dark-brown 

 below, pale-green above. Leaves loosely imbricate above, dis- 

 tant below, light-green, crisped, and recurved when dry ; lateral 

 spreading, rotuudato-ovate, largely apiculate, margined, serrate 

 at top and for half-way down ; lowest stem-leaves acuminate ; 

 nerve 0, or very short ; cells rhomboidal, small at apex, in- 

 creasing in size downwards, and large at base ; perichaatial long, 

 narrow-ovate, entire, very much acuminate, the niucro subulate 

 sharp, slightly serrulate at tip. Fruit-stalk 2 lines high, erect, 

 flexuous, with a sudden bend at top, red-brown below, very 

 hairy, with short patent hairs broad at bases or sub-muricated, 

 hairs longer above with a crest of long white fimbriae at top. 

 Capsule small, ovoid, horizontal, apophysate ; operculum flattish, 

 with a long decurved acute beak ; calyptra small, pale, largely 

 laciniate and fimbriate at base ; tip long, brown, shining, decurved.
