A couple from the Lily family

Pictured above is Streptopus amplexifolius (clasping twistedstalk). This species is distinguished from other members of the Streptopus genus by it's branched stem arrangement (Pojar). Greenish-white blooms occur either singularly or in pairs at leaf axils, bourne beneath the leaves (just visible in the photo, click to enlarge). The base of the leaves clasp the stems. Common at low elevations. Fruits range in color from yellow to red to dark purple.

Prosartes (formerly Disporum) hookeri (Hooker's fairybells). Easily differentiated from Streptopus when in bloom, this species bears flowers only at the end of the stems. There are two species in this genera native to western Washington, the other being P. smithii (Smith's fairybells). P. hookeri has hairs on the upper sides of the leaves and along the stems, as well as forward-pointing hairs along the margin whereas P. smithii exhibits smooth leaves and stems. Fruits are yellow to red in color and also often hairy.
