Description of New Coniferous Trees from California. By 

 Andrew Murray, W.S. 



The expedition, in the course of which the trees now to be 

 described were found, was undertaken by my brother, Mr 

 William Murray, last autumn. He was joined by Mr A. F. 

 Beardsley, a gentleman from whose energy and knowledge of 

 the mode of life in the regions they traversed, he derived much 

 assistance. They left San Francisco in the month of Septem- 

 ber, and directed their course northwards and eastwards, so 

 as to explore the country lying between the coast range and 

 the Rocky Mountains. For a great distance their researches 

 were not rewarded by the discovery of anything of much in- 

 terest or novelty, and they were almost despairing of success, 

 when they came upon one of those patches of country so cha- 

 racteristic of North-western America, in which were crowded 

 together a number of totally new species, as well as several of 

 the rarest of those which have been already described or intro- 

 duced into this country. 



Among the pines they found and procured seeds of Abies 

 nobilis and grandis, Pinus Jeffreyi, monticola, Benthamiana, 

 tuberculata, Lambertiana, &c. Whilst camped amongst 

 these their attention was a good deal directed to their growth 

 and habits, and some of the information which they acquired 

 regarding them might be practically useful to the cultivators 

 of them in this country. For instance, the difficulty of procur- 

 ing sound seed of Abies nobilis and Abies grandis is well 

 known. No collector who has met with it (and a number have 

 gone expressly to secure it) has omitted to send it home ; but 

 (with the exception perhaps of the seed sent by Douglas) I be- 

 lieve it has invariably arrived so bored and worm-eaten by 

 maggots, that it has germinated only in rare instances. The
