L. microphylla, and it is what is intended by the New Zealand plant 

 mentioned under that species in our Synopsis Filicum, both editions, 

 p 110. The name viridis seems to have originated with Colenso, and 

 there are specimens of old date in the Kew collection so named by 

 him. Upon the study of these, and what Mr. Field now sends, and 

 others received from Dr. Lyall, Messrs. Logan Sinclair, and 

 Haast, I am now fully prepared to acknowledge it as a perfectly dis- 

 tinct endemic New Zealand species. It is much dwarfer in habit 

 than the true L. micropJujlla^ B. Br., which is restricted to East 

 Australia, with closer, more compound, and broader pinnce, and maybe 

 told at once from all forms of trichommioides and microphjlla by the 

 regularly cuneate form of its ultimate segments and the almost Daval- 

 lioid (Odontolomoid) character of its sori, which at the most are not 

 more than twice as broad as deep. According to the classification of 

 our Synopsis it should, therefore, stand as follows : — 



32"^" L. VIRIDIS, Colenso AfSS. Stems densely csespitose, 1-3 inches 

 long, slender, naked, shining castaneo-ebeneous. Basal scales minute, 

 linear brown. Prond lanceolate, 3-6 inches long, broadest (1-1| 

 inch) a little below the middle, tripinnatifid, with a thread-like naked 

 flexuose rachis, brown like the stipe about half-way up, and 10-15 

 pairs of mostly alternate erecto-palent pinnce, the lower ones lanceo- 

 late-rhomboid 1-1 5 inch long, parallel with the rachis on the upper 

 side at the base, cuneato-truncate on the lower side. Pinnules 

 reaching down to a filiform rachis, obversely deltoid, the lowest shortly- 

 stalked, consisting of about 3-4 tertiary segments, which are regularly 

 cuneate in shape, 1^-2 lines long by a line broad. Texture mem- 

 branous, both surfaces being naked and bright-green. Veining 

 distant, simple flabellate. Sori subdavalloid, occupying the tips of 

 the cuneate ternary segments, the anterior valve simply a continua- 

 tion of the lamina, the posterior valve membranous, ^ line broad, 

 persistent, both glabrous and irregularly incised. L. microphylla,

SHORT NOTES. 



Callitriche obtusangula. — In the course of my arrangement of 

 the British collection at the Edinburgh Herbarium, I have come 

 across specimens of C. ohttisangula along with C. verna, collected or 

 communicated by Cai*penter. The locality given is " Bonds, Coombe 

 "Valley, Westbury, near Bristol " ; no date. The contrast in colour 

 between it and C. verna is similar to what I observed in the Kentish 

 specimens. C. verna has a much more lively green tint. — J. "F.
