Introduction<\/h1>\n

Pseudolithos migiurtinus<\/em> is endemic to northeastern Somalia<\/strong> (the old Migiurtinia region, including localities around Eyl). It grows on open, stony grit in full sun under desert to semi-desert<\/strong> conditions\u2014genuinely arid terrain rather than merely \u201cslightly arid\u201d\u2014within desert\/dry-shrubland biomes.<\/p>\n

Bottom line: this is a true arid-land stapeliad<\/strong> that lures small flies with carrion-mimicking cues from tiny, dark, urn-shaped flowers; actual pollen transfer is done by minute midges and other saprophilous flies<\/strong> attracted by the ruse.<\/p>\n

The Details<\/h1>\n

How it attracts pollinators<\/h4>\n

Like most stapeliads, P. migiurtinus<\/em> uses sapromyiophily<\/strong>\u2014mimicry of carrion\/dung. The small, dark maroon to reddish flowers are urn-shaped with a narrow mouth and tufted lobe tips. A faint foul odor plus the color\/texture guides flies to probe the flower throat and across the corona, where pollinia are picked up or deposited.<\/p>\n

Pollinators (what visits\/does the job)<\/h4>\n

Direct observations in the genus point to very small flies (midges)<\/strong> as effective pollinators. More broadly in stapeliads, saprophilous Diptera<\/strong>\u2014blow flies, house flies, flesh flies\u2014regularly visit and likely contribute to pollination of P. migiurtinus<\/em> where it occurs.<\/p>\n

What the plant looks like<\/h4>\n

A leafless, stone-like succulent<\/strong>, usually a single globose to short-cylindrical stem with a tessellated (\u201ccobbled\u201d) surface, typically 4\u201312 cm tall and ~2\u20136.5 cm across<\/strong>, colored green to ochre or reddish-brown depending on light stress. Flowers arise in small clusters; the tube is paler, the lobes deep red to maroon with short hairs. Fruits are the characteristic stapeliad paired follicles<\/strong>.<\/p>\n
