A. macrophyllum Pursh Fl. 267. (Larae LeAvepD Mapir). A_ tree 
50—90 feet high, 1—3 feet in diameter: leaves 6—12 inches long, nearly

cleft initio 8—5 sinuate, acute lobes, pubescent beneath when young: 
flowers yellow, fragrant, in crowded pendent racemes 3—6 inches long, 
appearing after the leaves: calyx petaloid, campanulate, the broad

sepals: stamens S—12 exserted, filaments hirsute at base style longer 
than the stamens, deeply 2-lobed: fruit densely hispid, the glabrous 
wing 1144—2 inches long. In mountain ravines and river bottoms, Brit.

* * Flowers in loose umbel-like corymbs or fascicles: fruit

A. glabrum ‘Torr. Ann. Lyc. N. Y. ii, 172. (*moorn Maprie). A shrub 
or small tree 6—30 feet high, 2—8 inches in diameter, glabrous through-

round-cordate with shallow sinus, 2—4 inches broad, nearly as long, 
more or less deeply 3-lobed or parted, the ovate acuminate lobes doubly 
serrate with acuminate teeth, conspicuously veined and reticulated: 
flowers few, greenish-yellow, somewhat corymbose, on short 2-leaved 
branchlets, appearing after the leaves: calyx campanulate, deeply 5- 
cleft, the spatulate segments about 2 lines long: stamens 8, shorter 
than the spatulate petals: fruit very smooth, with slightly spreading 
wings, about.an inch long. Along streams and on the highest moun- 
tains, Vancouver Island to California and the Rocky Mountains.

villous beneath and on the veins above when young, becoming glab- 
rate: flowers in loose 10—20-flowered terminal corymbs; calyx dark 
red, deeply 5-lobed or parted, the ovate acute sepals 2—3 lines long,

GLOSSOPETALON Gray Pl. Wright. ii, 29, t. 12. not Schreber. 
Low and rigid shrubs with slender spineseent branches, and 
small alternate simple entire leaevs, which separate in age by an 
indistinct articulation from a dilated scale-like minutely. 2-stip- 
ulate base; the setaceous-subulate stipules adnate to the scales, 
and small solitary flowers, terminating short axillary branchlets, 
or spur-like fascicles. Calyx deeply 4—5-cleft, persistent, its flat 
base within filled by an 8-10-lobed perigynous disk; petals 4 or 
5, inserted on the margin or under the edge of the disk, some- 
what withering-persistent. Stamens 8 or 10 inserted at the sin- 
uses of the disk, shorter than the calyx; filaments subulate, 
persistent: anthers didymous. Ovary 1-celled, of a single ovoid 
earpel, with style extremely short or none, anda depressed en- 
tire or obscurely 2-lohed stigma. Ovules 2, collateral or nearly 
so inserted on the ventral suture barely above the base of the
