ocular demonstration. One has beer 

 introduced from the neighbourhood of 

 Genoa by Captain Cook, of which there 

 is a young plant in the Horticultural 

 Society's Garden ; but it has not yet 

 shown any character differing from that 

 of the species ; a cone, however, which 

 we possess of this variety is smaller than 

 that of the species ; and the raised ends 

 of the scales are more prominent, ap- 

 proaching in a slight degree to the form 

 of those of the cones of P. Pinaster. 

 Mr. Lambert, in the second edition of 

 his Genus Pinus, has figured what ap- 

 pears to be a variety of P. halepensis 

 under the name of P. maritima ; but, as 

 he has given in his figure three cones, 

 of three different shapes, and as no 

 living plant in England is referred to, 

 nothing can be determined definitely 

 respecting it. We shall, however, give 

 the name among those of other varieties, 

 real or conjectural. 



1 P. h. 2 minor has the cones rather 

 smaller than the species. There 

 is a tree in the Horticultural So- 

 ciety's Garden, which, in 1837, 

 after having been 15 years 

 planted, was 20ft. high, with a spreading branchy habit; but with- 

 out any other marked difference from the species. 



1 P. h. 3 maritima, P. maritima Lamb. Pinned. 2.,t.6. According to 

 Mr. Lambert's figure, the cones of this 

 variety, in the different forms in which he 

 has given it, are all larger than those of 

 the species. The three cones given in 

 Mr. Lambert's plate are, one from the 

 Sherardian herbarium, which points down- 

 wards, and only differs from the species in 

 being thicker ; one collected in Greece by 

 the Hon. W. F. Strangways, which points 

 upwards; and one from a tree in Syon 

 Gardens, which no longer exists, but which 

 is stated in the text also to point upwards. 

 A tree in the Horticultural Society's Gar- 

 den, received from Sir Charles Monck,and 

 said to be the true P. marftima of Lam- 

 bert, is nothing more than P. Pinaster ; 



as is the one at Dropmore, received from Mr. Lambert himself. 

 It is somewhat more fastigiate in habit than that tree is generally, 

 but this appears to us nothing more than a variation. Mr. Lam- 

 bert has given the following particulars respecting the uses made 

 of this variety in Greece, from Dr. Sibthorp's papers, published 

 in Walpole's Memoirs : " Peukos, one of the most useful trees 

 in Greece. It furnishes a resin (lirctine), tar, and pitch (pissa); 

 all of considerable importance for economical purposes. Through- 

 out Attica, the wine is preserved from becoming acid by means of the 

 resin, which is employed in the proportion of an oke and half to 

 20 okes of wine. The tar and pitch for ship-building are taken
