2. (1) Leaves not tomentose, stem and leaf hairs stiff with enlarged bases; achenes glabrous 3
Leaves usually tomentose, at least beneath, hairs not stiff with enlarged bases; achenes
setuliferous 4
3. (2) Small, usually decumbent herbs; leaf lamina 3-veined at base; achenes compressed with 2
ribs; pappus reduced or lacking
Philoglossa
Robust, erect herbs or subshrubs; leaf lamina with 5–9 veins radiating from base; achenes
usually 4-angled; pappus of many awns or setae
Erato
4. (2) Anther thecae usually blackish; style arms of disk florets less than 1/3 as long as hipidulous
upper part of style shaft
Munnozia

longer 5
5. (4) Leaf lamina pinnately veined; leaves basal and rossettiform; corollas orange to reddishyellow
or reddish
Pseudonoseris
Leaf lamina 3-veined; plants with leafy stems; corollas yellow 6
6. (5) Inflorescence with all bracts or with all but basal bracts and branches subopposite or
alternate; receptacle scarcely alveolate, glabrous; stems with latex
Microliabum
Inflorescence with all or at least primary bracts and branches opposite; receptacle with
minute hairs, chaff or projections; stems without latex
Liabum
Key to the genera of the Mutisieae
1. All capitula ligulate, or rarely with mixtures of ligulate and bilabiate florets in one capitulum
as well as ligulate capitula on one plant
Hyaloseris
Capitula containing actinomorphic, bilabiate, or pseudoligulate florets, or mixtures there of
