scrap exists in the herbarium of the late Mr. Davies labelled "Llanthony" 

 which is probably this pansy. 



Another plant which we should look for abundantly in this district is the 

 Common Club-moss, Lycopodium clavatum. But it is most rare. The single 

 example I have ever seen was gathered by myself this year in Cwm Bwchel, near 

 Llanthony. Two other Club-mosses exist, but in a hardly less degree of rarity— 

 the Fir Club-moss, Lycnpodimn Selago, is the least rare, and occurs sitaringly at 

 one or two spots on the rocky hill sides, both in the Llanthony valley and again in 

 the Olchon dingle ; the Savin-leafed Club-moss, Lycopodium alpinum, is again 

 limited to a single tuft, which I found many years ago on the steep escarpment of 

 the hills over-looking Hay. 



Again, a plant we should look for commonly in this district is the Sundew, 

 Drosera rotundifolia, yet it is quite rare. The hills seem too dry to produce it, 

 except in very small quantity, though it does occur both in the Grwyne and 

 Honddu Valleys ; the other species, Drosera intermedia and anglica, are absent. 

 Again a fern which the naturalist would expect to find freely growing in their 

 mountain glens is the Filmy Fern, Hymcnophyllum Wilsoni, but lucky will he 

 be if he stumble upon a morsel of it, though it grows abundantly in the Brecon 

 Beacon range. It does exist in the Honddu Valley, but this is all that can 

 be said. 



Two or three more plants, which are interesting on account of their rarity, 

 must bring this paper to a close. One is the Field Gentian, Gentiana campestris, 

 specimens of which were sent to me by Miss Edith Gee, who found them in Cwm 

 Bwchel, near Llanthony. The only other habitat for it in our county is at Stoke 

 Edith, where it grows in abundance at one spot in the park. Another is the 

 Wood Cranesbill, Geranium sylvaticum. This fine plant is confined to a single 

 locality in the Honddu Valley, and another single locality in the Grwyne Valley. 

 One of their stations is in Breconshire, the other in Herefordshire. A single 

 locality is also known for it in Radnorshire ; and thus this plant is represented by 

 a single statio7i in each of the three counties. Northwards in Shropshire it seems 

 (see Leighton's Flora of Shropshire, p. 328) to become more plentiful. We lie upon 

 the extreme south limits of this plant, which has not been observed in Britain 

 anywhere south of Herefordshire. The Welsh Poppy, Meconopsis camhrica, is 

 another interesting plant of the Honddu Valley. It grows at a single spot in the 

 middle of a damp cliff, in a position which precludes any doubt of its being an 

 indigenous plant. The Welsh Poppy has a very restricted range in Britain, being 

 limited as a native plant to the Welsh counties with their borders, and the West 

 of Yorkshire. It is found in the Grwyne Valley as well as the Honddu ; but in the 

 former it is in rocks and walls by the river side, where there may be some doubt 

 whether it is not a " stray.'' 



The last plant I will mention, which is limited to a single locality in these 

 valleys, is the Rough-leaved Hawkweed, Hieracium prenanthoides, which occurs 

 along with the Geranium sylvaticum, at a single spot on one of the cliffs in the 

 Honddu Valley. Here, however, it exists in great abundance, making some few 

 yards of the cliff quite yellow with ics golden blossoms when in full flower. Along
