at a very short bow-shot’s distance, the Charybdis of tide-line destruction 
by wave and sun. Nereocystis has solved the problem by the floating 
dock. Its holdfast at the smaller end of the stalk serves as the anchor, 
fastened far enough off shore to prevent stranding at low tide; its hollow 
bulb, surmounting the larger, hollow end of the stalk is the float; attached 
to the bulb are the leaves, constantly at the surface, supple, tough, safe in 
storm, current, and varying tide. However, it has minor troubles, since 
in creating for its own fronds an excellent environment it has created also 
an excellent habitat for other forms as well. It is not uncommon to see 
the bulbs and stalks densely covered with delicate red and green algae, 
and hydroids and bryozoa. Rising from unoccupied territory, and creating 
for its fronds one of the best habitats among marine algae, N ereoc ystis 
Luetkeana challenges the respect of the botanist and the lover of nature

TWO NEW SPECIES FROM NORTHWESTERN AMERICA. 
Miss Epira M. Farr of Philadelphia has recently submitted to the 
writer a small collection of plants for identification. The collection was 
made in the mountainous regions of Alberta and British Columbia, chiefly 
in the vicinity of Banff, Lake Louise, Field, etc., during the summers 
of 1904 and 1905. Among other interesting rarities there are two which 
the writer has been unable to place satisfactorily in any described spea® 
These are characterized as follows: 
Castilleja purpurascens Greenman, n. sp.—Perennial, more OF less 
purplish throughout: stems erect or nearly so, 1 to 3°™ high, usually 
several from a multicipital caudex, glabrous or puberulent below, villous 
above: leaves sessile, subamplexicaul, linear to narrowly lanceolate, 1-5 
to 4.5°™ long, 1 to-7™™ broad, usually attenuate and acute, entire and 
undivided or occasionally 3-cleft near the apex, glabrous or the uppet egecrl 
what villous-pubescent, 3-nerved; the lowermost leaves much reduced: 
inflorescence terminating the stem in a subcapitate raceme, later elongating 
to about 7°™ in length, villous-pubescent; bracts ovate-lanceolate to oblong- 
ovate, 2 to 2.5°™ long, usually entire, occasionally cleft: calyx 1-5 —s 2.50 
long, and as well as the bracts varying in color from a deep purp's"" 
to’ scarlet and rarely to yellow tinged with red or pink, about equally 
divided before and behind, externally villous with glandular hairs ie 
mixed; the lateral divisions 2-lobed, lobes obtuse: corolla 2 to 3 lon: . 
galea about one-half as long as the corolla-tube, green or greenish-yerr™
