 Capitulescence

Heads are few per stem, mostly at ends of short,
ascending branches. |

pubescent in lines above. |
|
| Basal

winged petioles, often present at flowering. Mid- to upper stem leaves
are oblanceolate, becoming more sessile
upwards. |

spreading, and have a distinct green patch, which may be tinged with
purple. Rays are white. Disc florets are pale yellow or white, turning
