Updated 1/3/2024. Index to my other posts.
The purpose of this post is to gather some information about the Sphenotoma species and provide a key to facilitate their identification.
To assist with the Fitzgerald River and Surrounds project I have shown the relevant Local Government Areas in which the species occur (shires of Jerramungup, Kent, Lake Grace and Ravensthorpe):

Key
- Upper leaves of flowering shoots usually small, erect and appresed to stem
- Lower leaves recurved (all leaves recurved on new growth): gracilis
- Lower leaves not recurved
- Lower leaves 40–80mm long, robust shrub in grevices on granite: drummondii
- Lower leaves 35mm long or less
- Corolla lobes 5–8mm long about equal to tube: capitata
- Corolla lobes 2–3mm long much shorter than tube: parviflora
- All leaves spreading
- Bracts small: sp. Stirling Range
- Bract large, especially in lower part of inflorescence
- Corolla lobes 3–3.5mm long shorter than tube: squarrosa
- Corolla lobes 5mm long about as long as tube: dracophylloides
Note that leaves of squarrosa are longer than dracophylloides and recurved. Flower spikes of squarossa in spike whereas those of dracophylloides in almost globular head.
