454 Transactions. — Botany. 



miles usually containing 5 segments, their sides entire, bases 

 cuneate excised ; tips largely toothed or sub-lobed, each lobe 

 containing a single sorus, but 2 on the larger lower lobes ; 

 veins few, somewhat sub-flabellate and simple, not extending 

 to margin, their tips thickened. Sori sub-marginal, situated 

 on the inner vein of segment. Involucre small, 1 line long, 

 linear - oblong, very membranous, transparent, filled with 

 numerous closely-crinkled veinlets having double walls ; margin 

 crenulate. 



Hah. Dry sides of hills, shady woods south of Dannevirke, 

 County of Waipawa (where it is plentiful) ; 1888, 1889 : W. G. 



Obs. A very symmetrical neat species, differing consider- 

 ably from other known New Zealand species of this genus, 

 though approaching the preceding one {A. ornatum), and also 

 A. hookerianum, var. adiantoides ; and somewhat distantly 

 resembling small specimens of A. bulbifenim, but very dis- 

 similar from that plant in texture, colour, and dense persistent 

 scales,* in its slender and dry stipes, its narrower and more 

 distant stipitate segments, which are also laciniate-lobed, &c., 

 and in the position of its sori, with their peculiarly-veined 

 involucres. 



Order V. Hepatic^. 



Genus 7. Gottschea, Nees. 



1. G. clandestina, sp. nov. 



Plant small, f in. -lin. high, 3-4 lines wide at top, sub-obovate 

 tapering, sub-erect, scattered ; stems simple, white, succulent, 

 glossy, the smaller specimens leafy to base, the larger ones 

 with numerous dark-purple rootlets on their lower half; 

 leaves ovate-dimidiate, with 2 small plaits at each apical 

 margin ; anterior margin laciniate-serrate, the basal half 

 largely so ; posterior margin almost entire, with 3 (or 4) dis- 

 tant minute teeth ; the lower leaves distant, smaller and sub- 

 falcate, their tips rounded entire ; the upper leaves imbricated, 

 sub-acute, their tips finely serrate ; dorsal lobe two-thirds 

 length of leaf, its anterior margin entire rounded and produced 

 beyond leaf, the lower margin straight, at some distance within 

 that of leaf, its junction-ridge thickened, produced, serrulate ; 

 tip truncate, entire. Stipule large for plant, broadly elliptic, 

 1^ lines long, margined, bifid, each lobe largely trifid at top, 

 with 1-2 coarse teeth on each side ; laciniae large, irregular, 

 margins sinuate, acute not ciliate ; sinus long, narrow, irregular, 

 with 2 teeth at bottom near base, 1 on each side. Cells large, 

 sub-quadrate-orbicular, irregular, distant, not clear, filled, 

 guttulate and many-beaded. 



Hab. Scattered among dense patches of Ancura poly- 

 morplia, Col. (infra), low wet woods south of Dannevirke, 

 County of Waipawa; 1889 : W. C.
