five acres. It grows quicker than C. obtusa in youth, attaining in its fifth year a 

 height of 2 to 5 ft., in its tenth year 7 to 10 ft., and in its fifteenth year 13 to 20 ft. 

 It begins to bear fertile seed when about fourteen years old. It appears to be more 

 hardy in Prussia than either C. obtusa or C. Lawsoniana. (H. J. E.)

A tree, attaining in America 120 ft. in height and 18 ft. in girth. Bark about 

 \ in. thick, brownish grey, and separating on the surface into large thin loose scales. 

 Branches of the fifth year smooth, terete, brown ; those of the third and fourth year 

 roughened with persistent brownish remote leaves. Branchlet systems distichous, 

 on the upper part of the tree pendulous in vertical planes at right angles to 

 the stem, tri-pinnate, with alternate pinnae disposed in one plane. Ultimate 

 branchlets flattened, compressed, ^ in. wide. Leaves, \ to T ^ in. long, green, not 

 marked with whitish lines or streaks, appressed ; lateral pair conduplicate, acute and 

 minutely mucronate at the spreading apex ; facial pair flattened, rhomboidal, with an 

 acute or mucronate apex, and a shining median ridge, often furrowed longitudinally. 

 Leaves on the main axes equal in length, \ in. long, with acute free tips. 



Staminate flowers yellow, \ in. long, with eight to twelve stamens. Pistillate 

 flowers dark plum colour. Cones, ripening in the second year, and falling soon after 

 the escape of the seed, on the ends of short leaf-clad branchlets, dark brown tinged 

 with a glaucous plum colour, globose, \ in. in diameter ; scales usually four, rarely 

 six, bearing near their centre a prominent triangular sharp - pointed process, 

 occasionally covered with resinous glands. Seeds two on each scale, flattened- 

 pyriform, acute at the apex, reddish brown, without resin-vesicles ; with the broad 

 wings nearly \ in. wide. 



Seedling : Cotyledons two, \ in. long, sessile, linear, rounded at the apex. 

 Primary leaves usually in whorls of fours, occasionally in pairs or threes, in. long, 

 decurrent at the base, acute or acuminate at the apex, linear, green beneath with 

 indistinct stomatic bands. The stem in the first year attains about an inch in height,
