ITPRESSUS MACROCARPA. 215 



Cupressus macrocarpa. 



A tree 50 70 feet high with a trunk 3 4 feet in diameter 

 covered with thickish bark fissured into broad ridges, the branches 

 stout and spreading, in old age becoming tabuliform like those 

 of a Cedar of Lebanon. - In Great Britain a rapidly growing tree, 

 varying in. habit from broadly pyramidal with long spreading branches 

 to strictly fastigiate with erect branches, forms intermediate between 



the.se extremes being far more frequent than 

 either. Trunk mostly simple in the fastigiate 

 forms, often more or less divided in the 

 spreading and intermediate forms. Bark thin, 

 reddish brown, peeling off in longitudinal 

 shreds. Branches numerous, thickly set and 

 much ramified, the branchlets slender with 

 orange-brown bark and tetrastichous (four- 

 ranked) ramification, the herbaceous shoots 

 similarly ramified. Leaves bright grass-green, 

 dimorphic ; 011 the axial growths oblong, 

 acute, concrescent except at the acute tip ; on 

 the lateral growths smaller, deltoid - acicular 

 and imbricated. Staminate flowers about 

 Fig. 62. strobile of Ciipressus one-eighth of an inch long, four-angled, 

 consisting of eight stamens in decussate pairs 

 / each with an ovate connective bearing four five 



anther cells. Strobiles sub-globose, 1 1'5 inch in diameter, in clusters 

 of five nine or more on short stout peduncles and composed of eight 

 ten decussate pairs of rhomboidal, striated scales thickened at the centre 

 into an obtuse unibo, of which the upper and lowermost pairs are 

 sterile, the fertile scales bearing from twelve to twenty seeds each.

var. Orippsii. 



A so-called " plumose " form, the leaves instead of being appressed 

 are more or less spreading ; the branchlets shorter, more rigid, with the 

 tips of all the youngest growths light yellow. 



var. lutea. 



Also a " plumose " form with the whole of the current season's 

 growths light yellow which changes to the normal green of the species 

 in the second year. 



The habitat of Cupressus macrocarpa is extremely restricted ; it is 

 known to grow spontaneously only on a small 'area south of
