Description by Reid Moran in Cactus and Succulent Jorunal US 48: 227-228. 1976 :

Plant gray velvety pubescent on all exposed parts, with tapering pluricellular trichomes to 2.5 mm long.

Stems to 70 cm high or trailing to 1 m or more, 0.5 - 2 cm thick, glabrescent, becoming silvery gray, usually little branched but sometimes shrubby.

Rosettes 5 - 20 cm wide, of 8 - 17 leaves crowded at stem apex, or the lower somewhat separated.

Rosette leaves elliptic to oblanceolate or cuneate-obovate, acute to acuminate, 3 - 13.5 cm long, 1 - 3.5 cm wide, 4 - 8 mm thick, channeled ventrally acutely so towards base, the margins rounded, the base subterete, 5 - 8 mm wide.

Floral stems arising just below stem apex but by late anthesis as much as 8 cm below, 20 - 70 (-100) cm high, 4 - 13 mm thick, with 25 - 60 leaves below inflorescence, the leaves ascending to downcurved, elliptic to oblanceolate, acute to acuminate, channeled ventrally, short-spurred, the lowest to 7 cm long, 2.5 cm wide, 4 mm thick.

Inflorescence spicate to subracemose, dense to rather open, of 15 - 60 (-110) flowers, the bracts lanceolate to oblanceolate, narrowly acute, commonly exceeding flowers, the pedicels 2 - 4 mm thick, 0 - 2 (-4) mm long, the paired bracteoles linear, 5 - 15 mm long.

Flowers July to March. Calyx disk 4 - 6 mm wide, the segments mostly spreading or slightly reflexed, nearly equal or those of one flower differing by as much as one-third, triangular-lanceolate, narrowly acute, 5 - 15 mm long, 2 - 5 mm wide, 1.5 - 3 mm thick, biconvex with obtuse margins.

Corolla scarlet to castilian red, orange-yellow within, 9 - 15 mm long, 7 - 10 mm wide at base, 8 - 11 mm wide above, pentagonal with flattish sides, petals connate 3 - 5 mm, narrowly ovate, acute to subacuminate, apiculate, 3 - 5 mm wide, slightly ascending from top of corolla tube and not in contact above middle of free part, acutely keeled, the well-defined nectar pit with conspicuously thickened upper rim, filaments yellow, subulate, 5 - 8 mm long from corolla base, 0.7 - 1 mm wide at base, anthers yellow. .........

Cytology : n = 23, 25.

Note :

1. Echeveria coccinea was the first Echeveria to arrive in Europe, at around 1790. Seeds were sent to the Botanical Garden of Madrid, origin unknown, and in 1793 the Spanish botanist Cavanilles described and illustrated it as Cotyledon coccinea. Later it was found native in Mexico.

2. When in 1828 De Candolle erected the genus Echeveria for the New World Cotyledon species, E. coccinea became the type species of the new genus Echeveria.

3. In 1839 Schlechtendal described E. pubescens - obviously because he ignored the 1793 description of E. coccinea by Cavanilles. E. pubescens is not a species distinctly different from E. coccinea (as incorrectly stated by E. Walther, Echeveria, p. 390), it is only one of the variants of the very variable E. coccinea. Therefore the name E. pubescens is merely a synonym of E. coccinea and should not be used any longer.

4. Plants circulating as E. pubescens are almost always the hybrid E. 'Pulvicox'  and not the species E. coccinea.

5. E. coccinea is easily recognizable by the long bract subtending each flower and conspicuously exceeding the corolla, E. 'Pulvicox', the imposter, is devoid of such bracts.
