196 | МЕ. W. MITTEN ON THE SPECIES OF 
which Sande-Lacoste himself says he at first overlooked it, certainly differs both in the 
outline and substance of its leaves. 
8. MARTINELLIA JAVANICA, Mitt.—Scapania javanica, Gottsche in Nat. Tijdschr. Nederl. 
Indie, Nieuwe Serie, i. (1853) 575. 
This is in Мід. Ann. Mus. Bot. Lugd.-Bat. i. 298, as from Japan. It is a small 
brownish species. 
Another distinct species is :-— 
М. MICRODONTA, sp. n. Caulis crassiusculus simplex. Folia complanata, lobis minute 
spinuloso-denticulatis, basi cordatis, auriculis trans caulem productis eique appressis, 
angustis, haud decurrentibus; lobo ventrali ovali, apice rotundato rarius angulo 
parvo terminato, lobo dorsali concavo quadruplo minore, apice angulo subrecto 
acuto incurvo, ambitu subreniformi. 
Hab. Plover Bay, a locality in the Х. Pacific, brought thence by а seaman who picked 
a few Mosses in Kamtschatka and in Vancouver. 
Caulis 3 em. altus, eum foliis 3 mm. latus. Folia lobo ventrali 2 mm. longo, medio 
1 mm. lato, dorsali 1 mm. longo, denticulis remotiusculis e cellula unica acuta conditis 
ciliata. 
DIPLOPHYLLUM, Dum. 
9. D. ALBICANS, Dum. | 
Small stems amongst Lepidozia setacea, * Challenger’ Exp.; amongst Mosses, Nan- 
taizan, Bisset. 
These fragments all belong to the form “tasifolium.” Lindberg had this from 
Sachalin, and describes another species, D. plicatum, also from thence, which, from his 
description, must be nearer to D. Dicksoni, which last is found in N.W. America. 
JUNGERMANNIA, Linn. 
10. J. МІХГТА, Dicks. 
A few fragments amongst Cladonia, Bisset.
