PIPER—NEW OR NOTEWORTHY PACIFIC COAST PLANTS. 209 
plant may be is uncertain, as the specimens have not been found either at 
Washington or in the Gray Herbarium. No Douglas specimens could be found 
either at Kew or in the British Museum, but in both herbaria are undoubted 
specimens of Ligusticum scothicum labeled “ Fort Vancouver, ex Herb. Gre- 
ville.’ While it would not be strange to find this plant on the Washington 
coast, inasmuch as it is common on the shores of Alaska, it has been collected 
by no recent botanist. It is quite certain that the plant does not grow at 
Fort Vancouver, and that the label is erroneous. as many other plants have 
been recorded from this place which do not occur there, 
Pentstemon cinereus sp. nov. 
Cespitose, with several to many slender erect stems from a much-branched 
woody base, the whole herbage densely and minutely canescent-puberulent and 
the inflorescence glandular; leaves all entire, subcoriaceous, the basal ones 
numerous, spatulate-lanceolate, acute, the blades 10 to 20 mm. long, usually a 
little shorter than the petioles; cauline leaves about 6 pairs, lanceolate, broad- 
est at the sessile base, 2 to 38 mm. long, gradually reduced upwards, the mar- 
gins somewhat involute; inflorescence narrow and strict, 10 to 20 em. long, the 
puberulence becoming glandular especially on the peduncles and flowers; 
peduncles erect, 3 to 7-flowered; pedicels very short; calyx 2 mm. long, the 
broadly ovate sepals abruptly acute, not margined; corolla dark blue, tubular, 
10 to 12 mm. long, slightly bilabiate, puberulent on the outside. slightly hairy 
within; sterile filament bearded at the top; anthers splitting their whole length. 
Type in the U. S. National Herbarium, no. 690798, ccllected in dry rocky 
ground at Bend, Crook County, Oregon, July 4, 1907, by Kirk Whited (no. 
8055a ). 
The species is perhaps most closely allied to P. collinus A. Nels. 
Plectritis congesta minor Hook. Fl. Bor. Amer. 1: 291. 1834. 
The original specimens of Douglas were said to be from “ near the mouth of 
the Columbia.” The specimens at Kew, apparently the originals, are labeled 
“near the ocean.” They are merely small plants of Plectritis congesta, and 
have nothing to do with Plectritis macrocera Torr. & Gray, under which P. 
congesta minor Hook. was cited as a synonym in the Synoptical Flora. Plectri- 
tis macrocera is not known to occur west of the Cascade Muntains. 
Erigeron filifolius (Hook.) Nutt. Trans. Amer. Phil. Soc. n. ser. 7: 308. 1841. 
Diplopappus filifolius Hook Fl. Bor. Amer. 2: 21, 1834. 
In the original description this plant, collected by Douglas, was said to be 
“Common on the Great Falls of the Columbia; and barren grounds of the 
interior.””’ There has been doubt as to whether this name properly applies to 
the plant with yellow flowers named Frigeron peucephyllus by Gray,’ or to 
a closely related species with violet or purple flowers. The doubt is probably 
traceable to Hooker’s original description, where the rays are described as 
“ flavescentibus.”” In the British Museum there are three sheets of Douglas’s 
specimens labeled Diplopappus filifolius. One of these is inscribed “ Sandy 
ground near the Great Falls of the Columbia, 1825.” This plant is the species 
described as Hrigeron filifolius in the Synoptical Flora of North America, and 
the sheet is doubtless the type or a duplicate type. The other two sheets are 
labeled ‘‘ Dry grassy plains of the Columbia, 1826.” Both are Hrigeron peuce- 
phyllus Gray. In the Kew Herbarium are also three Douglasian sheets of 
Diplopappus filifolius Hook., but all represent the same species as the “ Great 
Falls” plant in the British Museum. Thus it appears that Doctor Gray’s 
treatment in the Synoptical Flora is correct and that Hooker was misled as 
*Proc. Amer, Acad. 16: 89. 1810.
