50 Transactions. — Botany. 



dendroifl, erect, liin. ln'gli ; stem dark red-brown, shining, 

 bare below, simple, also 8-branched about the middle, and 

 sometimes dichotomous ; tops of branches curviform. Leaves 

 alternate, rather distant on stem, patent (appressed and con- 

 niving in pairs when dry, and then slightly imbricate), orbi- 

 cular, 1 line wide, denticulate, pale-green, thickish, and 

 coloured (reddish) at junction with stem, and only slightly 

 adhering as if sub-petiolate, not decurreut ; much smaller on 

 tips of old branches, which are drawn out and very acuminate. 

 Cells minute, distinct, sub-orbicular, with dark walls ; the 

 centre and base of leaf black-dotted (^microscopically) in 

 transverse wavy lines. Fruiting specimens not seen.

Ohs. A peculiar neat-looking species, much resembling in 

 general appearance of stems and leaves the drawing given of 

 Jungermannia, falcata, Hook. (" Musci Exotici," tab. 89), now 

 AdelantJius fakaiiis, Mitten ("Handbook N.Z. Flora"). 



8. P. S2)enceria)ia, sp. nov. 



Plant densely tufted ; rhizome matted, creeping, wiry. 

 Stems slender, erect, wiry, shining, sub-translucent, brown, 

 somewhat dendroid in the large specimens, 2in.-2^in. long, 3 

 lines broad (including leaves), leafy to base with the leaves 

 decreasing in size, simple and branched ; branches few, lower 

 (one or two) diverging, long, flexuous, (male plant) generally 

 sub-fascicled above (top of main stem) into 4-5 erect equal 

 branchlets, each bearing a terminal spike, linear-lanceolate, 

 obtuse, flattish, canaliculate, distichous, li lines long, 10-15 

 jugate, their edges rounded, tips of perigonial leaves entire 

 and slightly decurved. Leaves distant, patent, alternate, 

 decurrent on dorsal side, biformed, olive-green : those on 

 main stem sub-orbicular, distantly cilio-serrate at apex and 

 upper portion of anterior margin, the posterior margin entire, 

 recurved, slightly amplexicaul, reddish at junction with a 

 wavy rumple or twist owing to leaf being set obliquely on 

 stem : those on branches broadly obovate and much smaller. 

 Cells very minute, orbicular, guttulate, crowded, obscure, 

 with smaller cellules in their angles ; slightly clearer and 

 more regular at extreme base ; those of perigonial leaves 

 elliptic and black-beaded. 



Hab. On trees, forests near Dannevirke, Countv of Wai- 

 pawa ; 1888 : Mr. H. Hill. 



Obs. I. This plant in its slender habit resembles P. proli- 

 fera, INIitt., although its main stems are both stouter and 

 wider and its branches not proliferous, with leaves more 

 closely and largely ciliate, alternate, and not coadunate ; and 

 its perigonial leaves are also entire. It is also allied to P.
