Adromischus Explained

Adromischus is a genus of flowering plants. They are easily-propagated, leaf succulents from the family Crassulaceae, which are endemic to southern Africa. The name comes from the ancient Greek adros (=thick) and mischos (=stem).^[1]

  • Adromischus liebenbergii subsp. orientalis^[5]
• Adromischus montium-klinghardtii
• Adromischus roanianus
• Adromischus subdistichus

Section 2 (Boreali)

Grooved, tubular flowers, with ovate-triangular, recurved lobes that are undulated on the margins. Anthers protrude from flower tube. Indigenous to the arid, summer-rainfall interior of Southern Africa.

• Adromischus schuldtianus
  • Adromischus schuldtianus subs. juttae^[6]
  • Adromischus schuldtianus subs. brandbergensis^[7]

  • Adromischus umbraticola subs. ramosus^[9]

Section 3 (Brevipedunculati)

Grooved, funnel-shaped flowers with acuminate-triangular, widely spreading lobes, born on long stalks. Inflorescence branched. Usually spreading or stoloniferous plants.

• Adromischus caryophyllaceus
• Adromischus diabolicus
• Adromischus fallax
• Adromischus humilis
• Adromischus nanus

• Adromischus inamoenus
• Adromischus maculatus
• Adromischus mammilaris
• Adromischus maximus
• Adromischus sphenophyllus

Section 5 (Longipedunculati)

Pale or pubescent inflorescence with elongated, lanceolate-triangular lobes.

• Adromischus cooperi
• Adromischus cristatus
  • Adromischus cristatus var. clavifolius
  • Adromischus cristatus var. mzimvubuensis
  • Adromischus cristatus var. schonlandii
  • Adromischus cristatus var. zeyheri
• Adromischus leucophyllus
• Adromischus marianiae
  • Adromischus marianiae var. hallii

  • Adromischus marianiae 'Antidorcatum'^[13]
  • Adromischus marianiae 'Bryan Makin'^[14]
  • Adromischus marianiae 'Herrei'^[15]
  • Adromischus marianiae 'Little Spheroid'^[16]
  • Adromischus marianiae 'Red Mutation'^[17]
  • Adromischus marianiae 'Tanqua'^[18]
• Adromischus subviridis^[19]

So-called Adromischus oviforme specimens are actually Adromischus filicaulis subsp. marlothii; Adromischus oviforme doesn't actually exist.
