202 MR. W. MITTEN ON THE SPECIES OF 
41. PoRELLA POLITA, sp.n. Gracilis, pinnatim ramosus. Folia lobo dorsali imbricata, 
leevissima, nitida, divaricata, semicordato-oblonga, apice rotundato inflexo denticu- 
lato, lobo ventrali parvo erecto-patente ovato, apice rotundato crenato denticulato, 
basi dentibus paucis spinosis. Amphigastria orbiculari-ovata, apice repanda, medio 
excavata, marginibus crenatis, basi spinoso-dentata. 
Hakone Pass, amongst Mosses, Bisset. | 
In size and colour this corresponds with Р. lævigata ; but the form of the leaf is more 
rounded at the apex, without the tendency to become acute; barren fragments only have 
been seen. 
42. P. GRACILLIMA, sp. п. Caulis pinnatus. Folia lobo dorsali imbricata oblata, apice 
incurva integerrima, lobo ventrali parvo erecto-patente ovato oblongo obtuso, basi 
interno externoque uni- bidentato. Amphigastria ovata, apice ligulata recurva, 
basin versus in umbonem parvum excavata, basi utroque angulo unidentata. 
Nantaizan, fragments with Moss, Bisset. 
Statura Frullanice tamarisci similis. Color sordide viridis. Folia subnitida. 
In size this is only comparable to P. chilensis. 
43. Р. saponica, Mitt.—Madotheca japonica, Sande-Lacoste, Syn. Hep. Jav. 105, t. xxi. 
Mixed with Frullania tamarisci and other Hepatice, Herb. Dozy et Molkenboer. 
It appears to be a small species, in which the stems are not distinctly pinnate and the 
leaves not incurved to the ventral side. 
44. P. PLATYPHYLLA, Lindb.—Jungermannia platyphylla, Linn. 
Fragments of a dark opaque green, ‘ Challenger’ Exp., appear to belong here. 
FRULLANIA, Raddi. 
45. Е. DILATATA, Nees.—Jungermannia dilatata, Linn. 
Fragments with a lichen, Bisset. 
46. Е. жоготтѕ, Nees. 
Enumerated by Sande-Lacoste. It is found in China. 
47. Е. JAPONICA, Sande-Lacoste іп Ann. Mus. Bot. Lugd. Bat. i. 311. 
. Japan, Siebold; ereeping over Dendropogon dentatus, Nikko, Dr. Woods ; Kintoki, 
Bisset. ; 
In general appearance not unlike F Tamarisci, but distinguished immediately by its 
entire stipules of an oblate form ; the perianth has not yet been found; but the invo- 
lucral leaves have lanceolate entire lobes. 
48. F. ТАМАВІЅСТ, Nees.— Jungermannia Tamarisci, Linn. 
‘Challenger’ Exp.; Nikko, Bisset; gathered also by Maingay. 
The specimens agree with the state usually found in Europe on trees.
