NOTE on YORKSHIRE PLANTS. 



Sagina ciliata near Leeds. — Somebody may have already noted the 

 occurrence of this pearlwort — Sagina ciliata (Fr. ) — in Ahvoodley Lane ; but, 

 even if that be so, it seems worthy of mention (rare as the plant is in the 

 West Riding-) that it was there this summer in some abundance and quite 

 finely grown. Whilst cycling along the lane last month I noticed it fringing 

 the base of a sandy wayside bank, and dismounted in the hope of gathering 



apetala. The concealed fruit with its closely-fitting calyx, however, soon 

 put an end to that idea ; and when a lens revealed the mucronate points on 

 two of the four sepals I concluded that it must be .S". ciliata. The plants in 

 mass were of a beautiful, almost translucent green, and many of them some- 

 what exceeded six inches in height. — A. E. Bradley, Leeds, ist October 1902. 







NOTES on LAKELAND PLANTS. 

 Menyanthes trifoliata at an Unusually High Elevation.— In July 



last, whilst botanising in the neighbourhood of Borrowdale, Cumberland, 

 I found the Bogbean {Menyanthes trifoliata) in pools near the summit of 

 Glaramara, and flowering freely, at an altitude of about 2,350 feet. — 

 Albert Wilson, 4, Eaton Road, Ilkley, 13th October 1902. 



Peucedanum sativum in Cumberland. — This plant, which is not in 

 Mr. Hodgson's 'Flora of Cumberland,' I found in October of this year (1902) 

 at Silloth. There was quite a large patch of it on the embankment of the 

 single rail that runs through the sandhills to the gun trial yard on the shore. 

 — S. Armitt, Rydal Cottage, Ambleside, 25th October 1902. 



Aliens in Cumberland. —At Silloth this October (1902) I found two 

 interesting- foreign plants apparently quite at home on the sandhills : 

 Solanum rostratum , which had been seen previously by Miss E. J. Glaister, 

 of Skinburness, but not recorded, and Solanum trijlorum, which was in 

 flower and making' good fruit. — S. Armitt, Rydal Cottage, Ambleside.

Heather on Humphrey Head.— On 27th September I paid a visit to 

 Humphrey Head in Morecambe Bay, North Lancashire. The day was 

 warm and calm, the tide was out and showed no symptoms of return, the 

 sands were firm, and an air of peacefulness (enhanced by the spectacle of 

 numerous g-ulls reposing on the waste) contrasted most forcibly with the 

 savage ruggedness of the mountain valley I had left two days before. 

 Walking- towards the Head I observed the limestone rocks charged with 

 fossils that flanked the shore, then having mounted the grassy summit, my 

 attention was immediately directed to some tufts of tiny, low-crouched 

 diminutive Heather that struggled to peer above the stunted, sheep-cropped 

 grass. Wretched, indeed, was the plight of the heather, so utterly different 

 from the splendid ' three-feeters ' conspicuous on the summit of Hawkshead 

 Moor on the previous day. Heather in a limestone district, and on soil 

 perched on a foundation of briskly effervescing lime ! It was rather a 

 surprise. So, having secured a small quantitv of the heath-clad soil, 

 I examined it analytically on my return hither. The soil (which was acid to 

 test-paper) was dried, passed through a 30-mesh sieve, etc., and extracted 

 with boiling- aqua regia. No effervescence whatever. The acid extracted 

 only 9 per cent, of its weight, and left behind a brown mass of very fine 

 granules of sand. The 9 per cent, included 4 oxide of iron, 2*9 alumina. 

 0*3 lime (CaO), leaving- i'8 of other constituents. That was enough ; the 

 wretched poverty in lime triumphantly explained the presence of this 

 eminently calcifugous plant on the grassv waste of Humphrey Head, but 

 I leave to those afflicted with ' distribution on the brain ' to account for its 

 passage across the limestone tract of the Cartmel district from the, say, 

 Upper Silurians in the neighbourhood. — P. O. KEEGAN, Patterdale, 3rd Oct. 

 1902.
