Littorella lacustris (Shore-weed) covered the margin of a pond 

 near; and among the short turf around, the curious little 

 dwarfed var. capitata of the Common Centaury grew. 



Around Llanberis we had our first glimpse of the beautiful 

 mountain Flora. Saxifrarja atellans grew abundantly in moist 

 places, even by the road- side ; Globe-flowers, Water Avens, 

 and Butterwort by almost every lake and stream ; and the 

 curious Lobelia Doitmanna, not yet in flower, but with its 

 buds well pushed up above the water, grew in the waters of 

 most of the lakes. In a wooded dell the sides of many rocks 

 were covered with the delicate fronds of the Filmy Ferns, 

 Hyinenophyllum Wilsoni and tunbridgense. A Hawkweed, H. 

 orarium, was also gathered, and Mimulus luteus was established 

 in several large patches ; and not far away grew Symphytum 

 tuberosum. lianunculus Lenormandi occurred in several places 

 near Llanberis, and we met with this species about Bedd- 

 gelert, and in Anglesea also. 



In the neighbourhood of TwU Dii, a teriflBc chasm 450 ft. 

 long, 100 ft. deep, and only 6 ft. wide, a crowd of new plants 

 grew. Sedum Rhodiola hung from the rocks in masses, with 

 bright green tufts of Oxyria digyna ; a few purple flowers of 

 Saxifraya oppositi/olia, trailing over the rocks, were still out, 

 and Silene acaulis formed bright pink, rounded cushions, the 

 flowers so close together as to hide the leaves. We could 

 scarcely stop to look at these, however, for we knew that 

 Lloydia alpina (the Mountain Tulip), the rarest of the rare 

 Welsh plants, grew near. Climbing down to the very brink 

 of the precipice, and looking carefully around, we saw perhaps 

 nearly thirty plants of Lloydia, but for the most part absolutely 

 unapproachable. However, by careful climbing, for the rock 

 was wet and slippery, and a false step might have been fatal, 

 three plants of Lloydia were at last reached. 



In Cwm Glas Bach we first came across the Alpine Meadow 

 Rue {Thalictrum alpinum), and by the streams there were the 

 most beautiful soft cushions, covered with large white flowers, 

 of the Moss Saxifrage {Saxifraga hypnoides) ; and in many 

 places the small delicate flowers of Alsine verna appeared, 

 almost hidden in the short grass. As we ascended the valley
