All the trees of this group hare more or less pyramidal forms when 

 young ; many of them have, or approach to, the form of a roimded cone 

 when they have attained a considerable size ; but 137, 161, 170 acqiiire 

 broad- formed heads ; the pyramidal form is retained by 142, 165, 172 ; 

 some, as 147, 148, are seldom more than bushes. The branches of 139, 

 163, 173, are long and pendulous ; of 161, 175, spreading ; those of 164, 

 165, 171, have a loose, and 147 a creeping habit. The colour in 154 is 

 sUvery ; in 161 glaucous ; in 173, 175, hght green ; in. 152 a sombre 

 glaucous green ; and in the others shades of dark green. The whole of 

 them thi'ive in inferior soils ; 139, 173, in dry, barren, and sandy soils ; 

 163, 165, 170, 172, in good sandy soils ; but the last three in a variety 

 of other soils, if not wet. P. variahilis and Pinaster with its varieties, 

 m sandy soils along the sea-coast, but not in wet or calcareous soils. 

 P. Laricio is of very rapid growth, P. Pinaster, Austriaca, Pi/renaica, 

 and Pallasiana are also rapidly growing trees. The timber of 138, 152, 

 153, 164, 165, 170, 171, 175, is of superior quahty. P. Pmnilio and 

 uncinata form good covers for game ; they will grow in very elevated 

 situations. Many of the members of this group supply the landscape 

 gardener with the means of imparting depth of shade to scenery.

176. P. Pinea h ? 50-60 ft. 179. P. Fremontiana, h ? 20 ft.

178. P. fragilis, s h. 181. P. Llaveana, 7i ? 



This group is a small one ; and from their impatience of cold in this 

 country, its members seldom rise above the size of large bushes. Pinea 

 and its varieties have a peculiarly flat head, and are of a dark green 

 colour. The fohage of 179 and 181 is glaucous, and that of 180 a vivid 

 green. They may be planted as shrubs in sheltered places.

 This remarkable tree is a native of the southern mountains of ChUi, 

 and is quite hardy. It is to be regretted that its congeners, some of
