The Trees of Great Britain and Ireland 



They also say that the trees are usually sound and free from hollow butts, and 

 produce a large proportion of lumber free from knots. 



Mayr^ states that each species of the cypress family, including Thuya, etc., 

 has a wood recognisable by a special odour, that of C. nootkatensis being the 

 strongest and most disagreeable. The wood of Lawson cypress, he adds, is so 

 strongly aromatic, that it can easily be smelt on approaching a saw-mill where 

 it is being cut up, and many pieces of the wood are so saturated with an oily 

 resin that they become heavy and reddish in colour. He speaks of the durability 

 of the wood in the highest terms, saying that, when used as piles for building in 

 swampy ground near the sea-coast, it lasts four or five times as long as that of 

 Douglas fir. 



The trees in this country are as yet too young and mostly too branchy to show 

 how soon these good qualities will be developed, but I have no doubt that in time it 

 will be one of our most valuable home-grown timbers. (H. J. E.)

A tree, attaining in New England 50 ft. in height and 2 ft. in diameter, and 

 in the south-eastern United States 80 ft. high and 4 ft. in diameter. Bark, an inch 

 thick, reddish brown, irregularly divided into narrow flat connected scaly ridges, 

 which are often spirally twisted around the stem. Branches of the sixth year very 

 slender, terete, brown, smooth, but retaining traces of the leaves, which roughen 

 with their brown acute spreading tips the branchlets of the third, fourth, and fifth 

 years. Branchlet systems alternate,^ somewhat umbellate or radiating, forming 

 short erect wedge-shaped expansions, tri-pinnate, with the pinnae more or less 

 m one plane and often directed to one side. Ultimate branchlets flattened, ^ in. 

 wide. Leaves, t^ to ^ in. long, glaucous green, and not marked with whitish lines 

 or streaks ; lateral pairs conduplicate, with mucronate spreading tips ; facial pairs 

 appressed, ovate-triangular, acute, flat or keeled ; most of the leaves marked on the 

 back with a conspicuous raised circular resinous gland. Leaves on the main 

 axes, equal in length, glandular, \ in. long, oblong, with a triangular mucronate 

 spreading tip. ^ 



Staminate flowers minute, dark brown, with five or six pairs of stamens, 

 ristuiate flowers with ovate acute spreading dark brown scales, and black ovules. 



pecuW branching of this species is described by Masters, in/.Li. Linn. Soc. (Bo,) xxvii. 288 (.890).
