Though very unlike the ordinary state of P. Menziesit, 
which is a much smaller plant with fewer flowers and much 
broader smaller often obovate or obcuneate leaves, there 
are so many intermediate states between them that it is 
impossible to challenge Asa Gray’s decision that they are 
one species; and indeed there are other forms no less 
distinct from both, as var. Newberryi, A. Gray, with rose- 
coloured flowers; var. Douglasii, A. Gray (P. crassifolius, 
Lindl.; Bot. Reg. vol. xxiv. t. 16), with quite entire oblan- 
ceolate leaves, and especially var. Lyallui, A. Gray, with 
linear-lanceolate leaves three to four inches long, and often 
racemose flowers. As is to be expected in a plant having 
so wide a range of variation, P. Menziesii has a corre- 
spondingly wide area of distribution, being found on the 
lofty Sierras of Western North America, from the sources 
of the Fraser River in British Columbia, southward to middle 
California; and from the sea-level at Nootka Sound, where 
it was discovered by Archibald Menzies, to an elevation of 
8000 feet on the Sierra Nevada, where I have gathered it 
SEPT. Ist, 1885.
