250 Transactions. — Botany. 



Obs. A very minute plant, wholly hidden but for its large 

 erect inflated whitish perianth. 



Genus 27. Zoopsis, Hook. fil. and Tayl. 



1. Z. flagelUforme, sp. nov. 



Plant slender, prostrate, glabrous, glistening, light-green ; 

 \ - 1£ inches long, J^th of an inch broad, much and dichoto- 

 mously branched ; main branches linear-lanceolate, flexuous, 

 composed of two rows of cells on each side of the central cord, 

 tips flagellate ; sides sinuate with sub-rotund or knobbed pro- 

 jections of large blunt cells, sub 3, or so, together, alternate and 

 at almost regular distances, with smaller cells intervening, and a 

 few scattered short and simple rootlets beneath peeping. Invo- 

 lucral scales long, irregular, lanceolate. Perianth large, lateral, 

 pedicelled, highly cellular, almost cancellate, much laciniate ; 

 lacinias long, each composed of two rows of large orbicular cells ; 

 also some of a single row of oblong cells ; pedicel thick. Fruit- 

 stalk 2 lines long, septate, cellules large and full of scattered 

 dark dots; capsule light brown, oblong; valves oblong-lanceolate, 

 obtuse, excessively reticulated with dark veins, the longitudinal 

 ones thick and wavy. 



Hab. Among other Hepatica on decaying logs ; wet forests, 

 Norsewood, County of Waipawa ; 1885 : W.C. (Same localities ; 

 October, 1885: W.C. 



Obs. A species having pretty close affinity with the only 

 other known (published) species of this genus, Z. argentea, 

 Hook. fil. and Tayl., but differing from that species in its larger 

 size yet narrower ; in being much branched, with flagellate tips ; 

 in shape, and in colour, and in the number, form, and position 

 of its cells. A truly elegant object under a misroscope. 



2. (?) Z. lobulata, sp. nov. 



Plant minute, tufted, glabrous, stems brownish, creeping, 

 3-4 lines long, dichotomous, sub-bipinnatifid ; brancblets or 

 lobes sub-erect, linear, almost filiform, about 1 line high, 

 emarginate, margins entire ; cells sub-orbicular, apparently 2-3 

 nerved ; light-green. Perianth lateral near base, short, laciniate, 

 thickish, opaque, brownish-red. Calyptra sessile, sub-obovate, 

 very membranaceous, reticulate, bearing a small reddish cellular 

 boss or umbo on the top, which is persistent. Capsule shortly 

 pedicelled, oblong, on a short, thickened, linear-oblong (or 

 apophysate) stem, striate, bursting at tip, mouth conniving. 

 Spores green, orbicular, trilobed. Elaters long, pointed and 

 spiral, remaining fixed in an irregularly pencilled mass at 

 mouth. 



Hab. On denuded rotten logs, in large continuous patches ; 

 shaded wet forests, near Norsewood, County of Waipawa ; 1885: 

 W.C,
