(wood near Azerley, 250 feet, very rare), and Gentiana amarella 
(widely scattered, but rare, and exceedingly pretty with its pale 
rose-coloured flowers). 
The Midland, or Intermediate type of distribution, is repre- 
sented by the nearly extinct Cypripedium calceolus, or lady’s 
slipper, which still grows at one or two favoured stations in 
Wharfedale, very properly ‘not for publication”; and Primula 
farinosa, one of the most beautiful of plants. Its flowers are a 
pale lilac-purple, with a yellow eye; the leaves are mealy pale 
green above, and silvery beneath. Its habitats “ stream-bogs” or 
bogs not stagnant. 
The British Intermediate type, or those which, though 
occurring throughout Britain, are most plentiful in the Midland 
district, is represented by the cranberry, Vacciniwm oxycoccos, a 
fastidious fruiter. 
The Scottish type, or those which range as far south as the 
North Midland districts, is represented by Trollius ewropeus, the 
globe-flower, which ascends to 1400 feet, on Greenhow Hill; it 
likes shallow valleys by running streams. Prunus padus, the 
heckberry (Danish hekke, hedge; ber, berry), or bird-cherry, 
which is common in the upper part of Nidderdale, from 800 to 
1200 feet. Towards the end of May the long white racemes of 
clustering flowers that adorn this mountain-loving species add a 
strange and characteristic beauty to the pleasing wildness of these 
subalpine dales. The London-pride, Saxifraga wmbrosa, grows 
wild on the limestone of Greenhow Hill, at 1400 feet, where it 
carpets for acres the gently sloping grass fields on the northern 
side. There is no reason for doubting that this is as true a 
British species as the very grass that grows with it. Who, it 
may be asked, would take the trouble to carry it up to a wild 
Yorkshire hill and plant acres of it 1400 feet above sea-level ? 
Surely such an enterprising person would have chosen a locality 
better calculated to bring him some reward for his trouble. 
“Mr. Tatham,” says Mr. Watson, in his ‘ Cybele Britannica,’ 
“deemed it wild in Heseltine Gill, West Yorkshire; and 
according to Mr. Brand, it grows ‘ On Craig-y-barns, a hill to the 
northward of the Park at Dunkeld, covering acres, and in some 
places to the exclusion of everything else, forming the entire 
turf. But for the occurrence of Hypericum calycinum, and other 
introduced plants, it would have been considered native. But
