Distribution : Mexico (Veracruz : Xalapa).
Description :
Stem < 5 cm long, 1 – 1.5 cm in diameter, sparsely branching.

Inflorescences racemes 30 – 50 cm, bracts easily detached, pedicels 4- 10 mm.
Flowers : Sepals widely spreading to reflexed, the longest < 5mm; corolla conoid-urceolate, 9 – 15 mm long, bright red or orange red.
Cytology : n = 18.
Note :
1. The plant Haworth described as E. lurida in 1831 originated in the botanical garden of Berlin. Haworth apparently ignored that it had already been described as E. racemosa by Schlechtendal & Chamisso in the previous year - i.e. Echeveria lurida and E. racemosa are identical. Pretended wild localities for E. lurida therefore always concern E. racemosa which may be more widespread than commonly thought; and pretended differences between E. racemosa and so-called E. lurida either reflect the variability of the former or are due to a misidentification of the latter.
2. The Illustrated Handbook of Succulent Plants (2003) cites Echeveria lucida Steudel (1840) as a synonym of E. racemosa. This is wrong twofold :
1. Steudel wrote : Echeveria lucida Haworth (not Steudel) and
2. ’lucida’ is simply a misspelling of ‘lurida’.
There is no Echeveria lucida Steudel.
