First Description by Rose in Addisonia 10 (3): 47, pl.344. 1925 :

 

The stem of White's echeveria is weak, usually less than four inches long, and is crowned by a dense rosette of leaves.

 

The leaves are fleshy, flattened, spatulate, acute, one and one half to two inches long, glabrous, pale green, with purplish margins or sometimes with a blush over the whole surface.

 

The flowering stem is sometimes one foot long, red, bearing a few small leaves.

 

The inflorescence is an equilateral raceme about four inches long, with ten to fifteen flowers.

 

Each flower is subtended by a small linear bract a half inch or less long.

 

The five sepals are linear, acute, unequal, and green.

 

The corolla is red, about half an inch long, with the five petals angled, erect but with spreading tips.

 

There are ten stamens, five of which are borne on the petals, the alternating five free.

 

Cytology : n = 150 ± 4

Note :

Kimnach (2003) has reduced Echeveria rauschii to a synonym of E. whitei. In view of the very different chromosome numbers - E. whitei n = 150 ± 4, E. rauschii n = ~100 - published by Ch. Uhl in Haseltonia 13, 2007, this is no longer justifiable and therefore E. rauschii is reinstated as species.
