Aylostera eos (Rausch) Mosti & Papini
A lot of confusion exists around this white or pale pink flowered species, with misapplied field collection numbers and interchange between A. eos, A. amblypetala, A. canacruzensis, and others. Several forms have been named, some of which have been found to be distinct enough to be separate species (A gavazzi, A. odehnalii, A. mixticolor, A. pelzliana, A. rafaellii, A. violascens).
Regarded by some as a yet another form of A. pygmaea or sometimes A. haagei. In places all three of these grow in proximity, but there is no evidence of hybridisation. A. eos was given specific status by Mosti & Papini (2011). Note that the former A. rosalbiflora is now included with A. eos, but the former A. rosalbiflora var. amblypetala is not: it becomes A. amplypetala, a species in its own right.
