find the upper limits of the oak, ash, beech, sycamore, holly, 

 cherry, and hawthorn. The roses and shrubby brambles (ex- 

 <?ept Rubus idcBus) are almost equally distant ; and with them 

 is found the upper limit of agriculture. At Clova, Ukx euro- 

 pceus exceeds cultivation by six or seven hundred feet ; in the 

 other three stations it is rather below. In none of them does 

 the climate admit the successful cultivation of wheat : Braemar 

 is too high ; Fort William is too wet ; Glen Clova, a narrow 

 valley shaded from the sun by high hills ; and Tongue, exposed 

 to a north sea, and with high ground to the south : — all there- 

 fore are equally unsuited. At Clova it has been tried, but 

 failed to ripen.

 Banksia media. 



B. media ; foliis cuneato-linearibus truncatis dentato-serratis basi atte- 

 nuatis : subter reticulatis venis venulisque glabratis lacunis tomen- 

 tosis, perianthii unguibus sericeis ; laminis glabris, folliculis glabrius-

 Description. — Shrub erect. Branches subverticillate and spreading wide 

 slightly ascending at the extremities, grey with short dense tomentum. 

 Leaves (3-7 inches long, 6-10 lines broad near the apex), scattered, pe- 

 tioled, spreading moderately, linear-spathulate, serrate, truncate, above 

 glabrous and shining, below reticulated, pale, pitted, and the pits filled 

 with white tomentum. Amentum (3 inches long, 2i broad) terminal, 

 cylindrical, its scales covered with red-brown tomentum ; the lower 

 flowers expanding a little before the upper. Perianth 4-partcd, segments 

 linear, narrow; claws covered with yellow tomentum on the outsid^ 

 glabrous withih ; limb green, streaked with brown, at first hairy, after- 

 wards subglabrous. 

 This species is placed by Mr Brown immediately after B. marcescens. It 

 promises to be a very handsome addition to the species in cultivation, 

 and is now flowering most freely in the greenhouse of the Botanic Gar- 

 den, Edinburgh, to which establishment it was obligingly communicated 

 from the Clapton nursery. The first amentum expanded its flowers in 

 the beginning of September, but as the whole plant is covered with 

 others in all stages, they will probably expand in succession for a very 

 long while. 



Euphorbia cruentata. 



E.cruentata; caule herbaceo, ramose, erecto, foliisque oppositis pedun- 

 culatis lanceolatis maculatis inequaliter serratis piloso; bracteis ii-
