| Identification | In a group of plants (Lactuca) that often look much alike, this one is a welcome relief. Its leaves are dissected into the narrowest segments of any Lactuca, usually linear or broadly linear, with the midrib being strikingly whitish. Moreover, the inflorescence is unique in being very long (a foot or more), unbranched, the heads narrow and sessile. The florets are pale yellow -- others in the genus are medium yellow or lavender-blue. | |
