I'AU'l in. 



white, having at the base a lan- 

 ceolate, long-pointed, persistent, 

 indurated scale. Catkins termi- 

 nal, sessile ; bracteated at the 

 base, with niiinerous lanceolate 

 cuspidate scales ; male catkins 

 numerous, simple, cylindrical, 

 lA in. long, dense. Stamens mon- 

 adeljihous. Anthers linear, 2- 

 celled, opening below longitudi- 

 nal!} . Crest roundish, convex, 

 repand. Pollen granular, sulphur- 

 coloured ; female catkins ovate, 

 ternate, furnished at the base 

 with numerous lanceolate, mem- 

 branaceous, loose scales ; green, 

 erect, finally brownish, spread- 

 ing. Scales short, roundish, 

 thick, marginate, imbricated backwards; keeled and convex above. Cone 

 generally terjiate, ovate-oblong ; 5 in. long, sessile, 2 in. in diameter at 

 the base, declinate-pendulous, ash-coloured, somewhat attenuated towards 

 the apex, decurved ; scales indurated, woody, dilated at the apex, tra- 

 pezoidal, depressedly 4-angled; ash-coloured, elevated in the centre from 

 a yellow conical tubercle terminated by a small spine. Seeds obovate ; 

 testa convex and crustaceous on both sides ; wing slender, membrana- 

 ceous, hook-shaped, oblong, acute, quite entire." (Lamb. Pin.,ed. 2., i. p. 14.) 

 The chiefcircumstance in which P. (L.)Fa\\asiana differs from P. Laricio, judging 

 from the trees at White Knights, is in the length of the cones: the leaves are 

 also larger than those of P. Laricio; and, on the whole, the difference may be 

 compared to that which exists between Tilia europae^a and T. e grandifolia, or 

 the pin de Hageneau and the pin de Geneve. At the same time, we think it 

 right to observe that there is a tree of P. Laricio in the botanic garden at 

 White Knights, which produces both straight and crooked cones, which, though 

 longer than those generally borne by P. Laricio, are shorter than those of 

 P. (L.) Pallas/rt?i«. The rate of growth appears to be the same as in P. Laricio. 

 The finest trees in England of P. (L.) Pallasittwa are, no doubt, those at 

 Boyton, which, Mr. Lambert informs us, are between 60 ft. and 70 ft. high. 

 There are a number of trees at White Knights, which are from 50 ft. to GO ft. 

 high, with trunks from l-lin. to 18 in. in diameter; but they are drawn up by 

 other trees. They are in some places intermixed with trees of P. Pinaster, 

 and the trunks are destitute of branches to the height of 20 ft. or 30 ft., so 

 that the only way of recognising them from below is by observing the 

 tortuous direction of their branches. There are trees at Dropmore, 25 ft. 

 high. Mr. Lambert remarks, in a letter to us, dated July, 1837, that, though 

 his trees produce plenty of cones annually, the seeds have never yet ripened. 

 Geography, History, Sfc. P. Pallasi««rt is confined to the central regions 

 of the Crimea, forming considerable forests on the western declivity of the 

 chain of lofty mountains which extend along the coast of the Black Sea. It 

 was first introduced into England by Messrs. Lee and Kennedy of the Ham- 

 jucrsn)ith Nursery, who raised a number of plants from seeds sent to them 

 by Professor Pallas, from the Crimea, about 1790, and it was sold by them as P. 

 tattirica. Of tiicse plants, some were planted at Boyton, about 1793, of which 

 a few survive, and form trees between CO ft. and 70 ft. high, although the soil on 

 which they grow is scarcely 2 in. thick, on a bed of solid chalk. About the same 

 time, from GO to 70 plants were planted at White Knights, by the Duke of 

 Marlborough, in good loamy soil, 20 or 30 of which still exist, and are from 

 .OO ft. to GO ft. high ; but, being crowded in a wood of indigenous and other 

 free-growing trees, they have not assumctl handsome shapes ; and, indeed, 

 there are only l)ranclics on their upper extremities.
