LIVERWORTS IN THE WESTERN HIMALAYAS. 81 



region were confirmed. The chief addition in the number of forms 

 occurring near Dalhousie was the discovery of a Porella near Banikhet 

 where it was found covering the trunks of some trees. It was also 

 noted that the number of Liverworts was larger beloiv Dalhousie than 

 actually in its neighbourhood. The forms noticed between Chhatrari 

 and Brahmaur were: — Athalamia pinguis, Gollaniella pusilla, Grim- 

 aldia 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 articul- 

 atum. 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 des- 

 cribed as aquatica but the inner pores is quite different form what is 

 described by Evans (l) or Stephani (4) and resembles the one given
