Published in Crassulacea No.5, 29. Sept. 2017. 


Synonym : Echeveria halbingeri var. goldiana  Kimnach (1997)

Type : CAS 413601 (not 413901 as indicated in the Spanish First Description).

Etymology : Named for Dudley B. Gold who according to Walther had collected the plant - see Note 1. below.


Distribution : See Note 3.  below.


First Description (in Spanish) by Walther in Cactáceas y Suculentas Mexicanas 4: 27. 1959 :


Plant glabrous, stemless, with offsets none or produced belatedly.


Rosettes densely leafy.


Leaves to 40 or more, broadly obovate-cuneate, very turgid, beneath rounded and not keeled, above shallowly convex and only slightly flattened near apex, the latter truncate and minutely mucronate, to 4 cm long, 25 mm wide near apex, less than 15 mm broad at base, lettuce green to dull light coffee-coloured.


Inflorescences 2 - 3, each a simple, secund raceme, peduncle to 40 cm tall, slender, erect, with 10 - 12 bracts, these linear-lanceolate, acuminate, flat above, beneath rounded, slightly spreading to recurved, to 14 mm long, pedicels slender, to 15 mm long, somewhat turbinate below calyx.


Flowers 8 - 10, strongly nodding in bud, sepals very unequal, longest to 10 mm long and lanceolate, others much shorter, deltoid, acute, lettuce green to dull light coffee coloured, corolla conoid-urceolate, 13 mm long and to 9 mm broad near base, only 4 mm in diameter at mouth, begonia-rose at base, greenish at apex, petals not keeled and only slightly hollowed within base, with small subulate apiculus below tips, carpels 7 mm long, nectaries to 2 mm broad, reniform, oblique.


Note :


1. Walther indicated that he had got this plant from Dudley B. Gold who would have collected it originally near Valle de Bravo, Estado de México. However Mr Gold disclaimed any knowledge of E. goldiana saying that it must have been collected by somebody else and that the locality very likely is wrong. At any rate, the plant has never been found near the Valle de Bravo.

2. The leaf colour indicated in the English description in Echeveria, p. 117, 1972, does not correspond to that mentioned in the Spanish protologue.

3. In a letter of 1 July 1963 to Reid Moran, Kimnach "called attention to the similarity of this plant to Esanchez-mejoradae [ > now E. hyalina ]. He found one green and so did I", Moran wrote.  This comparison is quite appropriate because indeed the plant on the black-and-white photos of E. goldiana could as well represent Ehyalina. So in all likelihood E. goldiana should be considered a synonym of E. hyalina. 

4. In Haseltonia 5,1997, Kimnach however reduced E. goldiana  Walther to a variety of E. halbingeri  Walther, stating : "This taxon seems very close to E. halbingeri, differing mainly in its green leaves, and seems best considered as one of its varieties." However a comparison of the descriptions of E. goldiana and E. halbingeri and of the photos of the two plants published in Echeveria, 117 & 121, 1972, reveals conspicuous differences between the two plants regarding the shape of the leaves as well as the shape of the flowers. Apparently Kimnach had forgotten that previously he had pointed out - rightly - the similaritiy of E. goldiana and E. sanchez-mejoradaeKimnach's re-combination does not make sense and is not followed here.
