GENUS PINUS. 103 



P. silvestris aurea. The Golden Scotch Pine. 

 Amongst the many varieties of the Scotch pine none can 

 equal the present either for free healthy growth or the beauti- 

 ful golden tint which pervades almost every part of the 

 foliage. The variegation is not inconstant, as is generally 

 supposed, but is markedly distinct the whole year through ; 

 but that there are worthless forms offered by nurserymen is 

 well known. This golden pine is beyond doubt one of the 

 most ornamental conifers we have, the deep bluish-green of the 

 normal foliage offering a marked and pretty contrast to the 

 rich golden-yellow of the variegated leaves. It grows freely, 

 a specimen that I have oft examined having for several years 

 kept pace with the species alongside which it was planted. 



P- silvestris monopiiyila. This must be ranked as 

 a very distinct, curious, and constant variety. At first sight 

 it may readily be recognised as a form of the Scotch pine, the 

 habit of growth being exactly similar, but the thin, open, and 

 airy appearance at once strikes one as out of the common. 

 This is due not to the leaves being produced singly, as the 

 name would indicate, but to the majority of the pairs of leaves 

 being united for almost their entire length, this imparting a 

 more open aspect to the specimen. The cones, comparatively 

 speaking, are sparsely produced, and decidedly more globular 

 in shape (shorter and thicker) than those of the species. The 

 tree stands exposure well, the largest specimen I have seen 

 growing in quite an open situation near Hemel Hempstead, 

 in Herts. 



P. silvestris pygfmsea is a very dwarf, rounded bush, 

 with thickly arranged branches and comparatively short leaves. 



P. Strobus, Linnaeus. The Weymouth Pine. South- 

 Eastern States of North America to Texas and Arkansas. 

 1705. Both as an ornamental tree and for the quality and 

 quantity of timber produced in this country, the Weymouth 

 pine has received a considerable share of attention. It is 

 perfectly hardy, free of growth, and not over-exacting as to 

 the quality of soil in which it is planted. At a distance the 

 tree is readily recognised by its light-grey, feathery appear-
