The morning of the 13th was spent by the same advance 

 party by the side of the Wye at Boughrood (Breconshire), 

 where the main party was joined on the arrival of the 2 o'clock 

 train. Fumaria officinalis L., and two other species were 

 found close to the station, in Radnorshire. The bridge over 

 the Wye had seven ferns growing upon it, viz., three common 

 species of Asplenium, Ceterach, Phyllitis, Polystichum aculeatum 

 Roth., and Polypodium vulgar e L. Close by, on the Radnor- 

 shire side, was more of Matricaria suaveolens Buch. 



The botany of the river banks is very rich indeed. Above 

 the flood mark, on the Breconshire side, the flora is again 

 characteristic of heathy ground, and includes Hypericum pul- 

 chrum L., Cytisus scoparius Link., Lathyrus montanus Bemh., 

 Potentilla erecta Hampe, Serratula tinctoria L., Campanula 

 rotundifolia L., Digitalis purpurea L., Melampyrum pratense L., 

 var: hians Druce, Listera ovata Br., Deschampsia flexuosa 

 Trin., &c. In the same locality is also found Orobanche major 

 L., growing on Cytisus; Malva moschataL., Prunus avium L., 

 Rhinanthus Crista-galli L., Primula vulgaris Huds., Euphorbia 

 amygdaloides L., Habenaria bifolia Br., Orchis maculata L., 

 Festuca elatior L. But the richest ground by far is the steep- 

 Avooded bank, reaching down to the water- washed rocks in the 

 river. The following Hst of plants is in illustration :— Thalic- 

 trum minus L., var: odoratum (Gren. & Godr.), Caltha palus-
