292 Andrew Murray's Description 



iana is duller and more opaque than the exposed part, and 

 the streaks or raised lines are less perceptible. In A, Pat- 

 toniana no such difference exists. The bract in A . Pattoniana 

 contracts at about two-thirds of its length from the top, and 

 has a projecting purple ear immediately before the contraction. 

 A. Hookeriana has no such ear, and the contraction takes 

 place at one-third from the top instead of two-thirds. This 

 ear is not to be confounded with a sort of projection, which 

 both have at the top angles. The seed and the wing of A. 

 Pattoniana are both about one- third shorter than in A. 

 Hookeriana, and the wing of the former has a purplish-brown 

 tinge at the top and back, which does not exist in the latter. 



This species was found high up the Californian mountains, 

 about lat. 41° N., where the ground was already covered with 

 snow, on the 16th of October. 



We have named this species in honour of Sir W. Hooker, 

 who has done so much for the botany of this country. The 

 species A. Pattoniana was justly named by the committee of 

 the Oregon Botanical Association, after Mr Patton of the 

 Cairnies, in Perthshire, a gentleman who is following out with 

 equal zeal and discrimination a series of experiments, having 

 for their object the ascertainment of what new pine and other 

 forest trees can be grown with most advantage in our climate. 



Cupressus Laiusoniana. Plate IX. 



C. ramulis quadrangulis mediocriter compressis flexuosis ; 

 foliis crassis decussatis quadriseriatis adpressis ; strobilis 

 polygonis pedunculatis ; squamis fere planis, mucronatis ; 

 seminibus planis, auriculatis. 



Habitat in California, in lat. 40° ad 42° Bor. 



Branchlets quadrangular, somewhat compressed ; leaves 

 decussate, ovate, glaucous, adpressed in four imbricated rows ; 

 cones polygonal, of a light brown colour, about the size of a 

 large pea, pedunculated ; scales, six in number, flat, rough, 

 light brown, corticaceous, irregularly four or five sided, with 

 an umbo or tooth in the centre, pointing straight outwards. 

 Seeds proportionally large, flat, somewhat ear-shaped. Branches 

 flexuose, crowded, ascending. 



This was the handsomest tree seen in the whole Expedition.
