This is Cotyledon Oreades, C. B. Clarke, (Umbilicus Oreades, 
Decne.) so placed on account of its 5 stamens and connate petals, 
which are conjoined for a length of 3 mm. As a matter of fact 
the number of the stamens is quite irregular. In Nos. F. 14,620 
and F. 15,118 there are 10, all fully developed, the epipetalous 
ones 5 mm. long (1 mm. shorter than the others), and adnate for 
half their length.. In F. 11,706 and Wilson 1191 the 5 epipetalous 
stamens are shrunken and abortive. In other gatherings (F. 
6511, F. 7212) we get, for instance, x or 2 abortive epipetalous 
stamens, or 6 petals, 3 of them with abortive stamens. In none 
are epipetalous stamens wholly absent. 
The two first-mentioned plants, with 10 functioning stamens, 
belong to a large race with up to 20 flower stems 4 to 5 inches 
high, and inflorescences with up to 7 (not 1-3) golden (not white) 
flowers. 
The ro-stamened form is excellently figured by Decaisne in 
Jacquemont’s “‘Voyage,”’ Atlas, ii, pl. 73, fig. 2, as Umbilicus 
luteus, a name altered in the letterpress of the same work (iv, 62) 
to U. Oreades ; there the stamens are stated to be five and the 
flowers yellow.

I am glad to have an opportunity of figuring this very inter- 
esting species, and of correcting an error regarding its leaves. 
The leaves of the rosette were described* as “‘basi rotundata,”’ 
and in discussing the plant I referred to them as “narrowed at 
the base and joined to the caudex in the usual Sedum manner 
by a very constricted attachment.”+ A fuller examination of 
the type shows that this statement was founded on an imperfect 
leaf.. The root-leaves are joined to the caudex by a broad clasp-
