250 Transactions. — Botany. 



Obs. This species is allied to G. pinnatifolia, Nees ; and 

 also to G. ciUiqera, Hook. f. and Taylor, another large species ; 

 but it is a much smaller plant than either, and widely differing 

 in habit, and the form of its compound laciniate cilia? and cells. 

 Sir J. D. Hooker has united those two species in the " Hand- 

 book N.Z. Flora," p. 514, but I venture to consider them to be 

 very distinct. This small species is a truly elegant plant, and 

 takes its trivial name from its nodding plume-like tips. 



5. G. homophylla, sp. nov. 



Plant small, prostrate on mosses, and sub-ascending. Stems 

 f-1 inch long, simple and forked near base, ovate-acuminate 

 and broadly lanceolate, 4 lines wide, leafy throughout, with a 

 few fine rootlets at base ; both sides of the plant nearly alike ; 

 colour a pale whitish- brown (which may, however, have happened 

 from being badly dried). Leaves closely imbricate, sub-falcate, 

 excessively thin, broadly ovate ; both dorsal and ventral lobes 

 sub-similar in shape, ovate-acuminate, the ventral a little more 

 acuminate ; margins entire ; tips serrate ; dorsal lobe concave, 

 united to ventral lobe within margin, which extends in a narrow 

 line beyond it ; the stem completely hidden on both upper and 

 under sides through the leaves closely and largely overlapping. 

 Stipules 0. Cells small, sub-orbicular and somewhat obscure, 

 with minute starry dots at their angles. 



Hab. Forests near Waikare Lake, County of Whakatane ; 

 1886: Mr. A. Hamilton. 



Obs. This is a most peculiar and very distinct species, 

 widely differing from all others known to me. Its upper and 

 under surfaces are so very much alike that it is difficult to 

 distinguish them, save by their rootlets at their bases ; there 

 are also its entire margins, and it being without stipules ; and 

 then the most curious structure of its cellules and their unique 

 star-like appendages. Unfortunately, I have seen but a few- 

 whole specimens (about half-a-dozen) ; it seems to have been 

 collected hastily among other and larger Bepatica and mosses, 

 whence I picked it out. 



Genus 16. Isotachis, Mitten. 



1. /. rosacea, sp. nov. 



Plant closely gregarious, erect, delicate. Stem rather stout, 

 dark-coloured, 3 inches high, narrow, 1 line wide including 

 leaves, leafy throughout, 1-2 branches above ; branches £-l£ 

 inches long, spreading ; tips rounded, nodding. Leaves very 

 close, uniform and regular, sub-opposite on main stem, and 

 opposite on branches, all rose-pink, (also the stipules,) sub- 

 quadrate, apices quadrifid ; lobes free, sinuses large, coarsely 

 denticulate ; tips acute ; dorsal margin entire ; ventral margin
