Aloe gariepensis, the yellow flowering form

As the name indicates, one finds Aloe gariepensis close to the Gariep, previously the Orange River. It thrives in the hot and dry climate of those parts of the Northern Cape. The leaves have characteristic longitudinal lines and the young plants have many leaf spots as well. The spots persist only in some plants. Leaf margins have sharp teeth and a horn-like rim.

Not all the plants have light yellow flowers as the one in picture. Many have red buds that only turn yellow when the flowers open. The long thin racemes are characteristic (Frandsen, 2017; Van Wyk and Smith, 2003; iNaturalist).
