Orver 5. HEPATIC. 
Genus 3. Puactocuma, Nees and Montagne. 
Plagiochila subsimilis, n. sp. 
Rhizome stout, creeping, long, irregular, densely covered with short 
brown hair, much-branched, with many long rootlets; main stems pretty 
close together, erect or pendulous, 6-8 inches long, flattish, suleated on 
back, very dark purple-brown almost black, sometimes forked below, 1-2 
inches from base, and occasionally each of those main stems again forked; 
bipinnately branched, sub-fastigiate ; branches crowded above, 3-5 inches 
from base, patent, plane, taken together 2-8 inches broad; stems rich 
red-brown and semi-translucent; lowermost pair of branches opposite, 
others sub-opposite and alternate; all, together with main stem, closely 
leaved throughout: leaves laxly imbricate, opposite, distichous, patent, 
dimidiate-ovate ; apices obtuse and rotund ; light green, translucent, finely 
and irregularly toothed /denticulato-ciliatis ) on ventral side and round the 
apex, dorsal side entire, slightly recurved and greatly decurrent ; those on 
middle of main stem subrotund and larger, above 1 line in length, decreas- 
ing in size downwards, lowermost very much smaller, alternate and 1 line 
apart, and sometimes slightly dentisulate also on dorsal edge; involucral 
leaves more rotund, and more closely and deeply ciliate-toothed. Perianth 
produced, 1 line long, elliptic or broadly obovate, apiculate (obtusus cum 
acumine), inflated, whitish-brown, semi-transparent, terminal on upper 
branches and on short lateral branchlets near the tops ; sometimes 2-3 
perianths very nearly together; lips very large, open, entire. Calyptra 
cylindrical, enclosed, half the length of the perianth; seta longer than 
perianth, erect and nodding; capsule exserted, free, oblong-ovate, rich deep 
brown. 
Hab.—On standing (living) and fallen rotten trees, and on earth damp 
sides of watercourses, ‘ Seventy-Mile Bush ” forest, head of the Manawatu 
River, Hawke’s Bay; 1875-1881. Some living trees have their trunks com- 
pletely hidden with the dense growth of this plant. 
A fine species, having pretty close affinity with P. stephensoniana and 
P. gigantea, and in the shape of its leaves with P. annotina; and belonging 
to that same dendroid section of the genus.
