very irregular in length, overlapping each other; branchlets 

 numerous, close-set, alternate. Leaves mostly pale yellowish- 

 brown, the upper layer and more exposed dark-orange and rich 

 bright red-brown ; main-stem leaves sub-imbricate above on 

 stem with crisp sub-vertical margins, having a fissured scaly 

 appearance, orbicular-cordate, very apiculate, margins entire 

 but slightly uneven, largely amplexicaul, the sinus broad and 

 circular, with several long irregular-curved fimbriae and ciliffi at 

 base ; branch leaves imbricate, distichous, sub-orbicular, apicu- 

 late (sometimes sub-acute and obtuse), margins entire with long 

 ii-regular laciniate fimbriae at base ; auricle clavate, dark-purple 

 in age with several long flexuous fimbria at base ; cells clear, 

 orbicular, with minute interstitial cellules. Stipules on main 

 stem large, sub-quadrate, 4-partite ; segments largely cihate on 

 all sides; ciliae long, recurved, flexuous, jointed ; stipules on 

 branchlets similar but smaller, with a dark boss or blotch at 

 central base, and bearing two small dark claviform appendages 

 similar to those on leaves, and ranging with them : cells oblong- 

 orbicular, very clear, each of the segments having a narrow 

 marginal line of compacted minute cells. 



Hah. On trees, often overrunning mosses, etc.. Seventy- 

 mile Bush, between Norsewood and Woodville, County of Wai- 

 pawa; 1885-86: W.C. 



Ohs. A species allied to the preceding, P. smaragdinus ; but 

 more nearly to P. claviger, and P. taijlori, Gottsche. It is, how- 

 ever, a much larger, robust, and coarser plant ; differing from 

 them, and from all known species, in its large clasping and fim- 

 briate stem-leaves, its largely fimbriate and ciliate stipules, and 

 in its rich striking colours. 



Genus 21. Madotheca, Dumort. 

 1. M. latifolia, sp. nov. 



Plant prostrate, creeping, diffuse. Stems stout, brown, 

 3-4 inches long, 2| lines wide, bipinnate ; spreading irregularly 

 over each other in loose horizontal layers, and so forming small 

 cushioned tufts ; branches alternate, short, flat, patent. Leaves 

 darkish-green when fresh, (young leaves and branchlets light- 

 green,) closely and uniformly set, much imbricated, convex, 

 reniform-orbicular, decurved, dorsal margin entire, the apex or 

 outer angle much incurved, base waved ; the ventral lateral 

 margin on stem very uneven ; lobule sub-orbicular-elliptic, larger 

 than stipule, crisp ; cells orbicular, with thick walls and minute 

 interstitial cellules ; involucral 4, oblong-ovate, (2 of them being 

 smaller and narrower,) largely ciliate ; ciliae jointed ; cells as in 

 leaves, only larger and clearer at centre and base ; a dark-green 

 outer leaf largely produced and sub-vertical, much incurved and 

 enwrapping the apical margin, finely ciliate ; capsule (immature)
