	Rubus spectabilis	Rubus lasiococcus
	salmonberry	roughfruit berry, dwarf bramble, hairy-fruit smooth dewberry
Habit	Rhizomatous, thicket-forming, woody perennial 1-3 m. tall, the stems bristly at least below, the bark brown and shredding.	Unarmed, pubescent, trailing perennial with stolonous, freely-rooting, herbaceous stems up to 2 m. long, the erect flowering stems up to 1 dm. long.
