TaxonomyJoseph Nelson Rose described Echeveria runyonii in 1935,[2] named in honour of Texas amateur botanist Robert Runyon.[4] Runyon had collected the type specimen from a Matamoros, Tamaulipas garden[5] in 1922.[6][7] Wild populations were unknown until 1990, when one was discovered by the staff of Yucca Do Nursery.[8]The cytology of Echeveria species is helpful in identification, as many species can be very variable in appearance; E. runyoni has 14 chromosomes.[2] DescriptionEcheveria runyonii forms a rosette {{convert|8|–|10|cm|in|abbr=on}} in diameter. Leaves are spatulate-cuneate to oblong-spatulate, truncate to acuminate, and mucronate. They are a glaucous pinkish-white in color and measure {{convert|6|–|8|by|2.5|–|4|cm|in|1|abbr=on}}. The single stem reaches {{convert|10|cm|in|abbr=on}} in length or more and a diameter of roughly {{convert|1|cm|in|abbr=on}}. Inflorescences are {{convert|15|–|20|cm|in|abbr=on}} tall and have 2 – 3 cincinni, conspicuous bracts, and pedicels approximately 4 mm long. The red flowers have ascending-spreading sepals to 11 mm and pentagonal corollas measuring 19 – 20 × 10 mm.[2]Echeveria peacockii has similar-coloured glaucous leaves, but its leaves are wedge-shaped with mucronulate (pointed) tips.[9]CultivarsSeveral named cultivars exist, including 'Texas Rose', 'Dr. Butterfield', 'Lucita', 'Tom Allen', and 'Topsy Turvy'. The last is a mutant form originated in California, with leaves positioned upside-down.[1] Hybrids
