NEW AND NOTEWORTHY WASHINGTON PLANTS. 
Cardamine callosicrenata, n. sp. Perfectly glabrous throughout : 
stems erect, 60 to 70™ high, purplish below, shining above, coarsely 
striate ; leaves all similar and pinnately trifoliate, or some of the radi- 
cal rarely simple ; terminal leaflets orbicular, 3 to 5™ long and nearly 
as broad, closely crenate or the uppermost lobed, the crenations tipped 
with a short blunt callous point ; lateral leaflets ovate, entire, mostly 
obtuse, ro to 15™" long: raceme ample: flowers white : pods 25 to 
30™ long, erect on widely spreading pedicels ro™ long : style stout: 
seeds light brown, about twenty in each pod. 
In springy places, Spokane, July 2 and September 27, 1896. 
This species has much the aspect of C. Lyadlii Wats., but is more 
nearly related to C. Brewert. 
DRABA AUREOLA Wats., described from Lassen’s Peak, California, is 
found sparingly in volcanic scoria on Mt. Rainier at 10,000 feet alti- 
tude. Only two other plants, Smelowskia calycina Meyer and Poa Let- 
termani Vasey, occur at higher altitudes on this peak. 
ERYSIMUM ARENICOLA Wats. has yellow flowers like others in the 
same group. It is not rare in its type locality, Mt. Steele, Olympi¢ 
mountains, and grows either in loose sand or in rock crevices. 
ARENARIA PALUDICOLA Rob. (A. palustris Wats.). This interesting 
species, first found in swamps near San Francisco, California, and later 
at San Bernardino by Parish, has been detected by Mr. Flett 
growing in sphagnum swamps near Tacoma. The Washington plants 
agree well with the specimens distributed by Parish, save that the stems 
are sparingly branched and the leaves are not at all flaccid. Some of 
the specimens are peculiar in that the leaves on the uppermost branches 
are decidedly reduced, but more of the specimens do not exhibit this 
character. Dr. Behr’s note in Erythea (Nov. 1896), predicting that 
this plant will some day be found in Alaska, seems likely to be fulfilled 
now that it is known to occur in Washington. 
STELLARIA OBTUSA Engelm. is not a rare plant in the Blue moun-
