THE TRUE CYPRESSES. 79 



No. 1. CUPKESSUS ATTENUATA, Oordoth, the attenuated-branch- 

 letted Cypress. 



Syn. Cupressus nivea, Lohh. 



„ Bourgeauii, Hort. 



Leaves on the young plants distant, spreading, slender, very 

 small, straight, and of a light glaucous green colour, broadest 

 at the base, and tapering to rather a blunt point ; those on the 

 laterals much shorter, thicker, and closer together, while those 

 on the adult plants are scale-formed, very short, closely imbri- 

 cated, and bluntly oval, with a sunken oblong gland on the 

 back, and very glaucous. Branches horizontal, very distant, 

 long, slender, and little forked, lateral ones alternate, very 

 slender, distant, and spread out somewhat in two rows. 

 Branchlets very short, thin, mostly opposite, and very slender, 

 somewhat four-sided, and loosely imbricated. Cones small, ter- 

 minal, on short scaly foot-stalks, and in large clusters, on the 

 upper branches. Scales irregularly four or five-sided, mostly 

 six in number, shield-shaped, slightly elevated in the centre, 

 and terminating in a short, blunt point, sometimes curved out- 

 wards. Seeds rather small, numerous, and surrounded with a 

 dull brown wing or margin, cut sloping at top and bottom. 



A fine glaucous bush, growing from six to ten feet high, with 

 numerous straight, small, slender spray, covered with obtuse- 

 pointed leaves, more or less spreading at their points and 

 rather distantly placed, especially towards the base of the 

 branchlets. 



This kind was found growing in moist situations, along the 

 banks of mountain streams, in the Shasta country, in Northern 

 California, and in the Oregon territory, by Lobb.
