Regarded as a form of Gonialoe variegata, Gonialoe ausana comes from southern Namibia. For comparison a photograph of Gonialoe variegata from the Oudtshoorn area is also included.
The differences between the two forms are not massive and they are easy to tell apart.
Gonialoe ausana - Leaves not keeled, olive green, with off-white yellowish spots. Inflorescence branched, Flowers pinkish red , perianth 2 to 3 cm + in length
Gonialoe variegata - Leaves, upper half keeled, dark green with whitish spots. Inflorescence unbranched, Flowers red , perianth 2 to 4 cm + in length. The flowering time is approximately in September and a second flowering time in November has been observed.
Note: Literature states that Gonialoe variegata can have a branched peduncle. I do not know if this occurs in plants of South Africa. The old Aloe book from Reynolds also shows a Gonialoe ausana that has an unbranced peduncle. So perhaps the above analysis does not carry much weight if the whole distribution area is taken into account.
