Burke: Solidago simplex

	Solidago simplex
	sticky goldenrod
Habit	Glabrous perennial from a short woody base or short rhizome, 0.5-8 dm. tall, usually more or less glutinous at least in the inflorescence and peduncles.
Leaves	Basal leaves oblanceolate to spatulate, toothed or nearly entire, blunt or rounded, up to 15 cm. long including the petiole, and 3 cm. wide, the cauline leaves progressively reduced and few.
Flowers	Inflorescence long and narrow to short and compact, the heads often with long pecuncles; involucre 4-6 mm. high, its bracts imbricate, blunt; ray flowers normally 8, disk flowers 13, all yellow.

	Solidago simplex
Identification notes	The similar S. multiradiata always has ciliate petioles (hairs along each edge), S. simplex never has these rows of hairs.
Flowering time	June-September
Habitat	Open, slightly moist areas from coastal dunes to alpine meadows.
Distribution	Occurring chiefly west of the Cascades crest in Washington; Alaska to Oregon, east to the Rocky Mountains, northern Great Plains, Great Lakes region, and northeastern North America. [WildflowerSearch map] [BONAP county map]
