Barkhausia setosa has not reappeared, being doubtless, as before 

 suggested, introduced with clover-seed from abroad ; it may however 

 be expected as an occasional visitant. 



A species of Phlox, which I noticed this summer at Darlington and 

 elsewhere, has been found at Sampford ; and Lepidium sativum is of- 

 ten seen by road-sides &c. It is not unlikely that both these plants 

 may ere long find their way into the list of naturalized species. 



It is probable that a few other plants will occasionally be disco- 

 vered in this neighbourhood, as it is many years before even a limited 

 locality is thoroughly explored, and there will always remain some 

 fields, woods and hedges unexamined, which may produce a rare or 

 local plant, confined to one spot in the district.

On the 11th of 7th Month our party again set out from Settle, and 

 crossed the hills toward Malham. On these we saw Thlaspi alpestre 

 in abundance, especially on the rubbish at the mouth of the lead- 

 mines. We gathered fine specimens of Polemonium cseruleum in the 

 fissures of some limestone rocks, near Malham-cove, where a valley 

 is suddenly closed in by a huge cliff, from under which a small stream 

 emerges. Here we noticed Draba incana. Geranium sanguineura, 

 Pyrus Aria, and the remains of Draba muralis, which, as well as Hut- 

 chinsia petrgea, was now dried up. Leaving this place, we crossed a 

 ridge of hills to Gordale-scar, a deep cavernous ravine in the lime- 

 stone, where the overhanging cliffs present a striking and fearful as- 

 pect. At the further end of this opening we ascended the tumbled 

 rocks of a waterfall, which pours from under a natural arch into the 

 chasm beneath. Near this place we saw Hieracium Lawsoni, Hip- 

 pocrepis comosa, Epipactis ovalis, Equisetum variegatum, Potentilla 

 alpestris, Ribes petrasum, and a remarkable form of Khinanthus 

 Crista-galli, which however passed into the common one. In a boggy 

 piece of ground near Malham Tarn, we gathered Bartsia alpina, and 

 on the adjacent crag, Polypodium calcareum, Ceterach officinarum, 

 and a few specimens of Hieracium hypochoeroides. A high wind ruf- 

 fled the waters of the tarn, and brought considerable quantities of Po- 

 tamogeton lucens, perfoliatus and prselongus to the shore.
