NOTES ON WEST AMERICAN CONIFERZ. 227 
Thuin and Poiret, to incline one to believe that the Pine of 
Monterey was certainly alluded to by them, for, besides being 
partially described, as to leaves, the tree was then, as now, 
abundant around that ancient embarcadero, visited by Col- 
lignon, and is, practically, the only pine that would be noted 
for miles around, except by keen-eyed botanists like Douglas 
and Coulter, who did not visit the region until 1830-1831. 
Nevertheless, all that has been said and written about the 
Loiseleur pine will apply to any three-leaved, maritime pine 
which the members of the Peyrouse expedition might have 
collected on their long voyage, and which, subsequently, was 
grown, feebly for a few years, at the Jardin des Plantes. 
Consequently, P. Californiana must be rejected; and the 
first name followed by a description sufficiently full for iden- 
tification must be employed for this species. 
When preparing in 1887 the Botanist’s Report upon the 
Pines of the Pacific Slope for the California State Board of 
Forestry, I entered into the discussion of the nomenclature 
of this pine with some detail and argued that David Don’s 
name of Pinus radiata, published in 1837, (Linn. Trans. xvii, 
442), was the rightful name of the species. Don’s description 
(being translated) reads: 
Pinus radiata. Erect trees attaining the height of about 
100 feet, with copious spreading branches reaching almost to 
the ground. Cones in clusters, ovate, about six inches long, 
ventricose at the external base; scales bright brown, shining, 
radiately-cleft, cuneate, dilated at the apex, quadrangular, 
truncate with a depressed umbilicus, those at the external 
base three times larger than the others, with the apex ele- 
vated, gibbous and somewhat recurved. 
The leaves were not seen by Prof. Don. They were rightly 
conjectured to be in threes. All these terms correctly desig- 
nate the large-coned form of the Monterey pine. The 
character ascribed to the cone-scales—“ radiato-rimosis,” 
variously translated as “radiate-scaled” and “radiate-spread- 
ing”—perhaps was suggested to Don by the radiating lines 
often found marking the apex of the larger, knob-like scales.
