Aylostera einsteinii (Frič ex Kreuz. & Buining) Mosti & Papini


One of the southernmost species, and quite variable over its range, becoming like A. aureiflora in places, to which it is closely related. As a result, several different varieties have been named in the past, but these are not constant. They include var. atrospinosa, var. columnaris, var. conoidea, var. karreri, var. neumanniana, var. pseudoeinsteinii, var. rubriviridis, var. schmiedcheniana and var. steineckei, some of which have been regarded as separate species at one time.

Characterised by its softish, bristly spines, hairy buds and thick-tubed yellow / orangish flowers with yellow centres and styles that are not fused to the tube.

Aylostera gonjianii, given specific status by Mosti & Papini (2011), was formerly regarded as a variety of A. einsteinii.
