THE MOUNTAIN PINE. 1$ 



of the Mountain Pine will be found in Sketches in Spain 

 by Capt. S. E. Cook (Widdrington), 1834. Loudon follows it 

 in his Arboretum. Numerous French writers, including Boppe, 

 Matthieu, Demontzey, etc., give fairly adequate accounts of the 

 tree, as well as Willkomm, and several Danish writers. The 

 seed of the Intermediate variety can be obtained from Rafn of 

 Copenhagen. For the seed of the Upright variety it is better 

 to apply to the French Department des Eaux et Foii'ts. 

 Application must be made through the British Embassy in 

 Paris. Both seeds are cheap, and can be relied on to germinate 

 well if treated in the same manner as Scots pine. 



The Nomenclature of the Mountain Pine. 

 By Marion I. Newbigix, D.Sc. 



This subject is admittedly difficult, one great source of difficulty 

 being that the growth-forms of the tree do not altogether corre- 

 spond to the cone-forms, which are fairly well defined. A useful 

 summary of the various classifications proposed is given in 

 Lebensgeschichte d. Blutetipjlaftzen Mttteleuropas, by Kirchner, Loew 

 and Schroter, with a suggested classification, on which the follow- 

 ing notes are based. 



If we examine the cones only we find that Piniis montana may be 

 split up into three well-defined subspecies — (i) uticittata, (2) pumiliOy 

 and (3) jnughiis. Upright and intermediate forms only occur in the 

 first, which is therefore the only one which directly interests the 

 forester. In this subspecies the cones are markedly unsymmetrical, 

 have an excentric stalk, and are narrowed at the base. The scale- 

 shields (apophyses) are better developed on the free side of the 

 cone than on that turned to the stalk, and are raised so as to form 

 a cap or pyramid. In this subspecies two varieties occur. 

 In (i) P. montana uncinata var. rostrata the shield is strongly 

 hooked, and the pyramid forming the hook is as high or higher 

 than it is broad. The pyramid is well shown in the lower left-hand 

 cone in the plate. This variety is especially western, occurring 

 naturally in Spain, the Pyrenees, the western Alps and western 

 Switzerland, It is typically upright, but under very unfavourable 

 conditions sports into the dwarf form. Such dwarf sports will, 

 however, apparently give seeds which reproduce the upright form. 

 In (2) P. tnontana uncinata var. rotundata the hook is less well 

 marked, the pyramid, if present, is not so high as it is broad, and 

 may be represented only by a cap in the upper part of the shield. 

 This variety is more widely spread than the other, occurring through- 

 out the Alps except to the west. It is cultivated in Denmark and 

 Germany, and occurs especially in the intermediate form, but is 

 sometimes dwarf. The dwarf forms come true from seed. In 

 brief, the true upright form is P. rnontana uncinata var. rostrata, 

 the true intermediate P. montana uncinata var. rotundata, but 

 both of these may also occur in the dwarf form. The dwarf forms 

 of these two varieties are either (i) sports, or (2) constant races.
