The species grows in sandy or gravelly soils in subalpine habitats.[2][3]

Description

Chaenactis nevadensis is a perennial herb growing several short stems just a few centimeters high surrounded by a basal rosette of small, woolly, multilobed leaves. The inflorescence arises on a short peduncle. Each flower head is lined with rigid, blunt-tipped, glandular phyllaries. The flower head contains several white or pink flowers with long, protruding anthers. The fruit is an achene with a pappus of scales.[4]

gollark: Median might not actually be the right term either, but it's probably close enough.
gollark: There are two *medians*. There are not two *means*. This is why I said "mean" and not "average" a lot.
gollark: Sure. What is that modelling?
gollark: But in most cases they are motivated by real world examples of some kind.
gollark: Probability distributions are just functions, and you can define functions with all kinds of fun properties even if they aren't actually things you would likely encounter in real life.
