with a ciliate callous cap; caryopsis 6™" in length, plump, 
pointed at the base, longitudinally grooved on the side toward 
the upper palet. 
This species has been confounded with S. vz//oswm Sm., from which it is 
separated chiefly by the character of the leaves. In typical S. vz//osum Sm. 
the basal leaves are short, flat, and rigid ; the cauline ones are also rigid, flat, 
tapering from the base to the pungently pointed apex, and they are usually 
divaricately disposed. This species is far more common throughout the 
plains of eastern Washington, while S. vi//osum Sm. was discovered on rocky 
exposed points along the Snake river. Type specimen was collected by the 
writer at Parker Station, Yakima county, Washington, July, 1898, and is in 
my herbarium. 
Hypericum bryophytum, n. sp.—A loosely tufted subaquatic 
annual, with smooth fibrous roots. Stems densely covered with 
foliage, glabrous, 2-5°™ long, rather weak, procumbent and 
branched near the base. Leaves opposite, obtuse, ovate to 
oblong or obovate, entire, larger ones 5™™ long and almost as 
wide, sessile, ascending, attached by a broad base, usually much 
overlapping, glabrous or glaucous on both sides. Flowers soli- 
tary or rarely cymosely disposed, small, barely surpassing the 
upper pair of leaves; the 4 sepals persistent, distinct, ascending, 
glabrous, usually obovate, 3™™ long; petals 4, very thin, shorter — 
than or equaling the calyx, deciduous or soon withering, deep 
yellow, elliptical or obovate, delicately nerved, with a fine fringe 
of hairs along the upper edge, otherwise smooth ; stamens numer- 
ous, equaling the corolla, separate, anthers orbicular; styles 3, 
distinct, persistent, slightly exceeding the stamens, terminated 
by small capitate stigmas; capsule septicidally dehiscent, tricar- 
pellary, many seeded; seeds light brown, cylindrical, 0.5™™ long; 
puberulent, longitudinally striate. 
This is a strictly alpine species, which in its native place is invariably 
associated with mosses, to which it bears a strong resemblance. It has 
frequently been referred to A. amagalloides C. & S., which has usually a 
lower altitudinal range and from which it differs in its smaller size, more 
numerous leaves, and fewer flowers. I collected it above timber line in the 
Olympic mountains, Clallam county, Washington, August, Ig00. Type speci- 
men (number 2833) is in the herbarium of Stanford University. 
Orthocarpus olympicus, n. sp.—An erect annual, 2-3% high. 
Stems smooth, slightly angular, usually dark brown on the
