132 TASMANIAX BUYOPHYTA, 



Radula pUcata, Mitt. — Reddish. Leaves obliquely 

 oblong, very obtuse, imbricate, decurved, 0.8 mm. long, 0.4 

 mm. wide, dorsal margin overlapping the stem ; ventral 

 Ir-be quadrate half as large as the leaf to smaller, little in- 

 llated below, not closely appresssd, apex broadly concave- 

 truncate, angles obtuse; cells 10 ^., walls thick, trigones, 

 not apparent, middle and lower cells much larger, margins' 

 with small irregular serrulaticns, cuticle coarsely verru- 

 cose. Perianth 1.7 mm., little flattened, 8-10 plicate^ 

 rnouth more or less fimbriate. 



Mt. Field. 



New Zealand. 



]?a(Ji(Ia uvifera, Tayl. — Leaves closely imbricate, over- 

 lapping the stem broadly ovate, oblique, apex obtuse, de- 

 cui'ved, 1.2 mm. long, 0.8 mm. broad; ventral lobe l-3rd 

 as large, closely appressed, bas3 very short, inner margin 

 broadly expanded, outer margin little curved connate 

 throughout, inflation slight, apex short straight, angle 

 small obtuse. Antheridia on amenta. Cells 10-12 ^f^._ 

 trigones large, cuticle convex to papillate. 



Mt. llartz. West Coast. 



New Zealand. Auckland Is. 



Radula ia>^)nanlca, St. — Leaves broadly ovate, obtuse,, 

 imbricate, strongly decurved, 1.2 mm. long, 0.6 mm. wide, 

 ventral lobe l-3rd as large, ovate truncate to rhomboid 

 longer than wide, strongly inflated, apex short, angle 

 obtuse, base rather broad ; cells 18 ^., trigones small,, 

 acute. Antheridia on amenta. Perianth 4 mm., clavate. 

 mouth broad, entire. 



Though much the appearance of R. pin/so/oha, it is 

 readily distinguished by the strongly decurved leaves. 

 This is not a distinct species, it is the form assumed by 

 Ii. aneurysmalis under favourable conditions. I have 

 specimens in wdiich the ends of the shoots of typical R. 

 aneuryxuialis have grown into the typical form of R. 

 ffisinanica. As the student will seldom find this condi- 

 tion, the descriptions are here still maintained separate. 



Mt. Hartz. Adamson Peak. Cradle Mt., etc. 



Radula, niittenii, St. — Leaves contiguous but not im- 

 bricate, broadly oblong, obtuse, slightly falcate and con- 

 cave; 1.5 mm. long, ] mm. wide, slightly overlapping the 

 stem; ventral lobe small quadrate, dightly inflated below, 

 appressed above, angle obtuse; cells 18 ^., trigones hardly 

 apparent, walls convex. Perianth slender clavate 3 mm- 

 lono-, mouth crenate.
