2158 ARBORETUM AND FRUTICETUM. PART III. 



pine from the Duke of Northumberland, and that the trees produced 

 were exactly similar to the Scotch pine. Pallas assures us that the 

 pine of Livonia and Lithuania differs not from the P. sylvestris : 

 masts, he says, are not made of any pecuhar species, as foreigners, 

 and more especially the French, think ; but they are all of the P. syl- 

 vestris. Those trees are chosen that have a yellow bark, and a tall 

 straight trunk, free from branches. {Desf. Hist, des Arb., ii. p. 619.) 

 In 1814", this variety was again brought into notice by the late Prp- 

 fessor Thouin, who published a tract on the subject, recommending 

 its culture, on account of the superiority of its wood to that of the 

 common French variety of P. sylvestris. M. Puvis {De FAgric. 

 du Gatinais, &c.) describes the pin de Riga as growing beside the 

 pin de Haguenau, on M. Vilmorin's estate at Barres, and rivalling 

 that variety in dimensions. The following are Mr. Lawson's remarks 

 on this variety : — " From the superior quality of the timber of 

 P. sylvestris imported from Riga under the name of red pine, to 

 distinguish it from that of J^bies communis, or white deal, it has been 

 considered advisable to procure seeds from the natural forests in the 

 neighbourhood of that place, and to the plants produced from such 

 seeds the above name is applied. They may at least be considered 

 as possessed of equal merits with such as are derived from the best 

 native forests in the Highlands of Scotland." (Agt-ic. Manual, p. 331.) 

 Seeds and plants of this variety may be obtained of Mr. Lawson 

 and M. Vilmorin ; and there are specimen plants of it in the Hor- 

 ticultural Society's Garden, in the arboretum at Kew, and at 

 Messrs. Loddiges. 

 Olher Timber Tree Varieties. The names of several might be given from 

 books; but, as we could neither accompany them by descriptions or 

 synonymes, nor refer to any place where living plants may be seen, we 

 consider that it would be of very little use. P. s. altissima, in the Hor- 

 ticultural Society's Garden, is a strong-growing variety, resembling 

 the pin de Haguenau, and is probably identical with it, though raised 

 from Caucasian seeds ; but P. altissima is a name more generally applied 

 to P. Laricio than to P. sylvestris. 



b. Varieties curious or ornamental. 



i. P. *. 6 genevi'nsis. The Geneva luild Pine. — There is a plant of this variety 

 in the Horticultural Society's Garden, a portrait of which is given 

 in our last Volume, by which it appears to be a low crooked tree, 

 with numerous twisted branches, extending considerably at the base. 

 There is a good specimen at Dropmore. We have already suggested 

 that this may possibly be the commonest and most worthless variety 

 of P. sylvestris which attains a timber-like size in France. ( See 

 p. 2153.) 

 1 P. «. 7 vionophylla Hodgins. — The leaves are long and glaucous, and 

 those of each sheath are generally attached to each other through- 

 out their length ; though when the points are taken between the 

 finger and thumb, and the apparently single leaf twisted, it gene- 

 rally separates into two, and sometimes into three leaves. We 

 have only seen one plant in the Horticultural Society's Garden, to 

 which it was sent by Mr. Hodgins, nurseryman, Dunganstown, near 

 Wicklow, about 1830. 



I P. «. 8 scariosa ; P. scari(isa Lodd. Cat.,e<l. 1836. — A French variety, 

 introduced about 1820; but the plant at Messrs. Loddiges's is small, 

 and scarcely appears different from the s[)ecies. 



1 P. «. 9 intermedin. — This is a Russian variety, of which there is a plant 

 in the Horticultural Society's Garden, having slender young shoots 

 depressed towards the stem, and leaves shorter and less glaucous 

 than those of the species.
