Description

This is a petite annual herb producing a short, glandular stem along the ground or somewhat upright to a maximum length of about 18 centimeters. The fleshy green leaves are oval in shape, with the larger ones roughly lobed and up to 4 or 5 centimeters in length. The inflorescence is borne on a short peduncle. The flower head has a base of overlapping green phyllaries which form a cup to hold several small white ray florets. The center is filled with yellow disc florets with purple anthers.

The fruits are small achenes of two types. The ray florets yield hairy, curved fruits with no pappus, while the disc florets yield fruits with a long, hairlike pappus.

gollark: Heavpoot wanted me to track "average letter frequency", and is also my alt sometimes, but that would be bad for performance probably.
gollark: I'm sure you'd like to think so.
gollark: Maybe I'll implement an average word length function in minoteaur's editor, to spite you, then.
gollark: I did, I think I would know.
