174 MR. W. MITTEN ON THE SPECIES OF 
Rami triunciales, ramulis lateralibus, semiunciam vix superantibus, cum foliis 2 mm. 
lati. Folia inferiora fusca, apicalia tantum viridia, levia, vix nitentia, firma. 
Intermediate in appearance between the Madeiran М. intermedia, Brid., and N. levi- 
gata, Hook. f. & Wils. Fl. №. Zealand, more nearly resembling the first; all these 
species are remarkable for their very obtuse and very slightly undulated leaves. 
104. NECKERA HUMILIS, sp. n. Monoica. Rami humiles, pinnatim ramosi. Folia 
compressa, dorsalia tumide imbricata ovata obtusiuscula excavata, lateralia patentia 
ovalia acuta complicata cochleariformi-concava, apicem versus transverse rugulosa, 
integerrima, nervo tenuissimo ultra medium producto, cellulis apicalibus rotundis, 
inferioribus ovalibus, basalibus ad angulos condensatis, omnibus minutis parietibus 
pellucidis ; perichzetialia erecta ovali-lanceolata convoluta. Theca immersa ovali- 
oblonga, operculo conico acuminato, peristomio dentibus angustis attenuatis. 
Calyptra parva dimidiata pilosa. 
On bark in very small quantity, ‘Challenger’ Esp. 
Rami vix unciales, ramulis brevibus, cum foliis 2 mm. lati. Folia pallide viridia 
nitida, siccitate vix mutata, setate fusca. 7 
The appearance of this Moss is like that of young М. crispa. 
105. N.PusrLLA,sp.n. Rami breves, inordinatim pinnati. Folia compressa subsecunda, 
lateralia patentia uno latere complicata, dorsalia oblonga ovaliave, inde elongata, 
latiuscule acuta, omnia levia, margine apicem versus minute serrulata, breviter 
binervata, cellulis apicalibus ovalibus, inferioribus longioribus elongate oblongis. 
Perichzetium foliis erectis convolutis ovato-lanceolatis acuminatis, thecam oblongam 
ad medium usque tegentibus. 
A very few stems creeping on bark, with short free branches, * Challenger’ Exp. 
Rami vix 2 cm. longi, cum foliis 2 mm. lati, ramulis pluribus irregularibus. Folia 
levia, nitida. | | 
The very incomplete specimens show this species to be in foliage somewhat like 
N. complanata; but the capsule is almost immersed. Тһе М. complanata in Miq. Ann. 
Mus. Bot. Lugd. Bat., gathered in a barren state by Siebold, may belong to this.
