Taxonomy and etymology

Joseph Nelson Rose described Echeveria runyonii in 1935, named in honour of Texas amateur botanist Robert Runyon.{{cite book|author1=Eggli, Urs |author2=Newton, Leonard E. |title=Etymological Dictionary of Succulent Plant Names |publisher=Birkhäuser|date=2004|pages=207|isbn=3540004890|url=https://books.google.com/books?id=u2n5vusQ1DEC&q=Echeveria+runyonii&pg=PA207}} Runyon had collected the type specimen from a Matamoros, Tamaulipas garden{{cite journal |first=William |last=Scheick |title=Echeverian Beauty among the Rocks |journal=Texas Gardener |date=July–August 2012 }} in 1922.{{Cite web |url=https://plants.jstor.org/stable/10.5555/al.ap.specimen.us01014098 |title=Isotype of Echeveria runyonii Rose, J.N. 1935 [family CRASSULACEAE] |website=JSTOR Global Plants|publisher=JSTOR |date=2011-05-25 }}{{cite web |url=http://collections.si.edu/search/results.htm?q=record_ID:nmnhbotany_2164724 |title=Echeveria runyonii Rose ex E.

The cytology of Echeveria species is helpful in identification, as many species can be very variable in appearance; E. runyonii has 14 chromosomes.

Echeveria is named for Atanasio Echeverría y Godoy, a botanical illustrator who contributed to Flora Mexicana.Gledhill, David (2008). "The Names of Plants". Cambridge University Press. {{ISBN|9780521866453}} (hardback), {{ISBN|9780521685535}} (paperback). p. 149

Description

Image:Echeveria runyonii 1.jpg

Echeveria 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.

Echeveria desmetiana has similar-coloured glaucous leaves, but its leaves are wedge-shaped with mucronulate (pointed) tips.{{cite book|author=Cactus and Succulent Society of America|title=Haseltonia: yearbook of the Cactus and Succulent Society of America, Issues 6-10|year=1998|page=81}}
