Distribution : Mexico (Hidalgo, Querétero, Michoacán, San Luis Potosí, Zacatecas, Jalisco), 2100 - 2600 m.

 

First Description by Rose in Bulletin of the New York Botanical Garden 3:7. 1903 :

Acaulescent, glabrous throughout.

Basal leaves in a dense rosette, elongated-lanceolate, thickish, about 10 cm long, 1.5 - 2 cm broad, acute, dark green and somewhat mottled.

Flowering branches stout, 60 - 80 cm long, their lower leaves 8 - 10 cm long.

Inflorescence paniculate, the lower branches bearing 3 or 4 sessile flowers arranged along one side of the branch, the upper flowers in the panicle axillary and sessile.

Flowers : Sepals very unequal, somewhat spreading, fleshy, acute, corolla pale lemon-yellow, 10 mm long, petals free nearly to the base, acute at tip and slightly spreading.

Cytology : n = 28

Note :

1. * According to Walther the name "maculata" refers to the blotched leaves of the plant cultivated at Washington, resulting from its having been infested with mealy bugs. That means the leaves of this species are not blotched. Neither are blotches a means to distinguish E. paniculata var. paniculata and E. paniculata var. maculata. Whether this interpretation is correct cannot be verified.

2. In Haseltonia 5, 1997, Kimnach wrote : E. paniculata var. maculata "differs from E. paniculata var. paniculata only in its more succulent leaves, more expanded sepals and longer, pure yellow corolla". This is not correct ; according to the First Description by Rose, the size of the corolla of E. maculata is the same as that of  E. paniculata  - 10 mm. Unfortunately Kimnach based his comment on Walther, Echeveria, 1972, instead of on Rose.

3. The inflorescences of E. paniculata  are variable, either with one-flowered and two-flowered branches and with a terminal flower opening before some below, or with inflorescence branches as elongate (one- or) few-flowered cincinni, the lower flowers subsessile, the uppermost (including the solitary) with long pedicels (Moran in Cactus and Succulent Journal US 40(1): 39. 1968).

4. The photos on crassulaceae.com are not correct, the structure of the inflorescence does not correspond and the flowers should be plain yellow.
