than six months later, April 6, 1841, that the Vincennes left 
Hawaii for the northwest coast of America, and these islands 
supplied a rich harvest to the botanists of the expedition. 
The expedition arrived off the bar at the mouth of the Columbia 
River late in April, 1841, and proceeded north along the coast, 
entering Puget Sound about two weeks later, and this remained 
the headquarters for several months. Brackenridge, with 
Pickering, accompanied a party into the interior, under the com- 
mand of Lieut. Johnson. This party proceeded in a general 
easterly direction across what is now the center of the state of 
Washington as far as Lapwai in Idaho, and returned by a more 
southern route, through Walla Walla, up the Yakima River, and 
over the mountains to the headquarters at Fort Nesqually. 
Upon the return of this party, Brackenridge accompanied Mr. 
Eld on his survey of Gray’s Harbor, going down the Chehalis 
River. The trip into the interior and that to Gray’s Harbor, 
each of about six weeks’ duration, occupied the entire summer; 
and early in September Brackenridge, with Rich and severa 
other members of the scientific corps, joined Lieut. Emmons’ 
overland party to San Francisco, while the sqadron sailed down 
the coast to the same place. The overland party went up the 
Willamette River, and through the Umpqua and Shasta regions 
to the headwaters of the Sacramento River, which was followed 
toitsmouth. It was on this trip, near Mt. Shasta, that Bracken- 
ridge, who had dropped behind the rest of the party and was’ 
hurrying to rejoin them, hastily gathered an odd-looking plant 
that had attracted his attention. It was the fifth of October 
(1841, not 1842 as has been stated erroneously in all accounts of 
the discovery of this plant), and the season for flowers was long 
past, but the specimen was sufficient to show evident relation- 
ship to the group of pitcher-plants known, then and now, only 
from east of the Rocky Mountains. Not until nearly ten years | 
later, in May, 1851, was this California pitcher-plant collected, 
in the same vicinity, in flower, so that it was possible to give a 
correct scientific description of the genus Darlingtonia, or, as it 
is now known, Chrysamphora. 
The members of the scientific corps were finally all re-united
