Layia Glandulosa, White Daisy Tidytips

There are far fewer white-flowered than yellow-flowered asteraceae species, so such plants are much easier to identify. Characteristic features of layia glandulosa include the broad petals, which have two deep notches at the tip, and the long, bristly white hairs which cover the stems, leaves and phyllaries, often topped by spherical black glands. Plants may have a distinct scent. Lower stem leaves are usually lobed, while those high up the stem are undivided.

Flowerheads have between 3 and 14 ray florets, usually pure white though sometimes light creamy yellow, around a center of up to 100 yellow disc florets, which produce yellow anthers when mature. Ray florets are around 3/4 of an inch long. Phyllaries are dark green, all the same length, and fused for most of their height, curving outwards only towards the top.
