OF THE GENUS PINUS. 613 
The same author gives numerous bibliographical references, 
pp- 211, 212, 215, which it is not necessary to repeat in this 
place. 
In the germinating seeds of P. montana I have observed a 
slender caulicle bearing five incurved, somewhat three-sided 
cotyledons. 
P. majellensis of Schouw, Conif. d’Italie (1845), from La 
Maiella in Southern Italy, is referred by Parlatore to P. Laricio ; 
but the resin-canals are distinctly marginal in a specimen given 
me by the late Mr. Groves of Florence, who collected it in the 
originally cited locality. 
58. Pinus Pines, Linn. 
A well-known species inhabiting the Mediterranean region and 
observed also in Croatia and Syria. In altitude it occurs from 
the sea-level to 3000 ft. Bubani, in his ‘ Flora Pyrenaica,’ cites 
numervuus references to this Pine from Homer to Dodoens. By 
some of the older writers it was named P. domestica, by others, 
as by Bauhin, P. sativa. There is a specimen in the herbarium 
of Linneus. 
The famous forest near Ravenna, consisting of this species, was 
destroyed by frost in 1879, as graphically described in the 
*‘ Gardeners’ Chronicle,’ n.s. xv. (1881) p. 736. 
The peculiar round-headed habit of this tree is familiar to 
Italian travellers and is well exemplified in a tree at Kew. The 
buds are elongate apiculate, pinkish; the bark of the trunk 
pinkish-brown, much cracked and separating in irregular oblong 
flakes. The young rind is pale pink. The male flowers are in 
cylindrical racemes, each about 15 mill. long, orange-coloured, 
surrounded at the base by persistent, subcoriaceous, lanceolate 
perule fringed at the margins. The young cones are clavate- 
pyramidal, the apophysis obscurely 4~5-sided with a rhomboid 
apophysis and a deflexed, deltoid, compressed umbo. The edible 
seeds are very large, with a very narrow wing, and the testa 
covered with a purplish powder. The radicle is stout, the 
caulicle erect cylindric. Cotyledons 11, three-sided, smooth but 
with marginal sete. Primotinous leaves adnate, cylindric or 
awl-shaped. 
The histology of the leaf is interesting. In the primordial 
leaves the transverse section is boat-shaped. There is a single 
layer of hypodermal cells beneath the epidermis thickened at the
