DOLGELLEY (Dolgellau, dale of hazels), a market town and the county town of Merionethshire, North Wales, situated on the streams Wnion and Aran at the north base of Cader Idris, on the Cambrian and Great Western railways, 232 m.
According to Evelyn (Sylva, p. 35, 1664), hazels "above all affect cold, barren, dry, and sandy soils; also mountains, and even rockie ground produce them; but more plentifully if somewhat moist, dankish, and mossie."
The upper regions of Mt Elgon, Mt Debasien and Mt Agoro are clothed with forests of conifers - juniper and yew - and witch-hazels (Trichocladus).
The alpine vegetation on all these lofty mountains is of a mixed Cape and Abyssinian character - witch-hazels, senecios, lobelias, kniphofias, everlasting flowers, tree heaths and hypericums. The really tropical vegetation of Buganda is nearly identical with that of West Africa, but there is no oil-palm.
