plants. Few countries possess such a number of species witMn 

 restricted spaces as North West America ; and the enormous 

 growth and great beauty of many of the trees, especially the 

 Pines, in that quarter, gave an interest and attraction to his 

 introductions beyond those of ordinary discoveries. The climate 

 of Oregon, too, was similar to our own, and consequently the 

 new plants introduced were hardy. To attempt to particularise 

 Douglas's discoveries in North West America would require a 

 book for itself. It wUl be sufficient to remind the reader of a 

 few of the most important. Among trees it is to Douglas that 

 this country owes PiNUS Lambeetiana, whose stupendous 

 dimensions almost ecpial those of Wellingtonia gigantea and 

 Taxodium sempervirens ; P. insignis, the green foliage of which 

 is perhaps the most pleasing and refreshing to the eye of any 

 of the fir tribe ; P. ponderosa ; P. contoeta ; P. sabiniana, 

 remarkable for its great hooked cones, nearly as large as a 

 child's head ; P. monticola ; Picea beacteata ; P. nobilis, 

 perhaps the loveliest of the silver firs, if not of all the conifers ; 

 P. AMABiLis ; P. GEANDis ; Abies Menziesii ; and last, the 

 best of them all, which by happy fortune has been named after 

 Douglas himself, A. Dotjglasii, a tree whose beauty and value is 

 now universally known and recognised. Among numerous shrubs 

 the Mansanita, the Ceanothi, the red-floweiing and other Eibes, 

 and various of the laurel family, may be mentioned, and amongst 

 the more lowly the Calochorti, Cyclobothras,'''' Broditeas, CoUo- 



!L?f ?. * Several Calochorti and Cyclobotlirie were sent liome by Douglas, but unfortu- 



nately were not reared to x^erfection. Even yet their treatment appears not 

 generally understood, as notwithstanding their beauty, and that they are by no 

 means rare in California, they are still seldom to be met with in this country.
