region were confirmed. The chief addition in the number of forms occurring near Dalhousie was the discovery of a Porella near Ranikhet where it was found covering the trunks of some trees. It was also noted that the number of Liverworts was larger below Dalhousie than actually in its neighbourhood. The forms noticed between Chhatrari and Brahmaur were: — Athalamia pinguis, Gollaniella pusilla, Grimaldia indica, Marchantia nepalcnsis, Pellia calycina, Porella (25 species), Badula sp., Frullania sp. and Plagiochila sp. Between Brahmaur and Kugti the following were met with:—Athalamia pinguis, Fegatella conica, Marchantia nepalensis, Pellia calycina, the last three going as far as the Kugti village, the last inhabited place on this side of the pass. A species of Porella was also met with a little lower down.
It will be seen therefore that there is nothing peculiar in the distribution as compared with the distribution in other parts of the Ravi valley. The forms were more numerous at higher levels up to a certain limit than at lower.
Trans-Himalayan region.
This part has been travelled by many people who collected plants during their travels but in most cases the collections were restricted to flowering plants. Very recently Stewart (5) visited this country and he has given a list of Cryptogams and Phanerogams. He does not» however, mention any Liverworts in the list.
The writer did not come across any Liverworts in Rupshu, i.e., from the Baralacha to the Tagblang la. In Ladak proper two species were met with:—Marchantia polymorpha and Plagiochasma articulatum. The first is pretty common in moist situations in many places which are comparatively low and was very abundant at Leh on the sides of drains, forming big patches. It was also fairly common at Kargil. The second was seen only at Leh and it was found forming a small patch just outside the town. The writer did not see any other Liverwort between the Baralacha on the one side and the Zoji la on the other. One would have expected more Liverworts at least just near the Zoji la owing to greater moisture but the cold probably prevents their growth.
Plagiochasma articulatum resembled the ordinary Himalayan form in all respects except that the appendages of the scales are a little broader and the line of the junction of the two successive shoots is not so well-marked. The specimens of Marchantia polymorpha are rather curious. The thallus is thin and broad as in the variety described as aquatica but the inner pores is quite different form what is described by Evans (l) or Stephani (4) and resembles the one given
