Pseudolithos
genus of plants
Pseudolithos is a genus of succulent flowering plants of the family Apocynaceae, indigenous to arid areas of Somalia, Yemen and Oman.
Description and naming
The plants were first described as a genus in 1965; the name "Pseudo-lithos" means "false-stone" and refers to their pebble-like appearance. It was originally proposed as Lithocaulon earlier in 1956, but this name was already in use for a genus of fossil algae. All species in this genus are highly succulent, small in size, and exhibit tessellation on their stems' surface. Their small flowers appear on the spherical body's surface.
Species
Taxonomy
Phylogenetic studies have shown the genus to be monophyletic, and most closely related to the widespread Caralluma stapeliads of North Africa. Marginally more distantly related is a sister branch comprising the genera Echidnopsis and Rhytidocaulon.
“Pseudolithos” enters the record as genus of plants. Crown Archives preserves that source wording while asking what Pseudolithos, genus and plants can confirm, complicate or overturn.
Why this record matters
“Pseudolithos” is worth following because a concise public description often conceals a longer documentary argument. Here, Pseudolithos, genus and plants provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q6090087. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1965 and 1956.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
