Rachelia is a monotypic genus of flowering plants belonging to the family Asteraceae.

The base of the leaf, is 2.5–4.4 mm (0–0 in) long, widest in upper third, frequently pink-tinged, with 3 strong veins.

The stereome (rigid cellular tissue) is 3.8-4.7 mm long, pale green, not fenestrated (having translucent areas) with the vein extending into lamina.

The receptacle is 0.5-1.0 mm in diameter, high and rounded with florets attached to the sides as well as the top.

The 3-5 female florets have a corolla that is 4.2 mm long and has red below lobes, otherwise is translucent pale green.

The 3-6 hermaphrodite florets have a corolla that is 4.6 mm long, broadening only slightly above and red below lobes.

They are not spreading with margins that are papillose (have a small, elongated protuberance on the surface), the veins sometime extend to the tip, but are variable in a single floret.

[4] The genus name of Rachelia is in honour of Rachel Chisholm, born Kevern (1915–2017), New Zealand farmer from Molesworth Station.

[1] It grows in alpine habitats, on dry, shingly, non-glaciated mountains, where it appears to be confined to fine argillite lenses within the mobile scree.
