Tulista marginata (Haworthia marginata)
This plant and its close relative Tulista pumila were long included in the genus Haworthia, but they differ in having a stouter multi-branched flower stalk, and also in their chunkier flowers. DNA evidence shows that they are a distinct lineage, and they have now been put in their own genus, Tulista. From south of the Langeberg mountain range in the southwestern part of South Africa.
