Blake — New and Noteworthy Compositae 45 
which DeCandolle’s earlier name was established. A recent col- 
lection of S. Dombeyana is the following, in the Berlin Herbarium: 
between Piura and Hacienda Nomala, Peru, 23 Mar. 1912, Weber- 
bauer 5934. 
SIMsIA EXARISTATA Gray, Pl. Wright. ii. 87 (1853); Blake, 
Proc. Am. Acad. xlix. 380 (1913). This species, like several other 
members of the genus, proves to have two varieties differing only 
in achenial characters. The typical plant, which may be called 
var. epapposa (S. exaristata Gray, l.c.), has awnless and strictly 
glabrous achenes. To S. exaristata must also be referred the fol- 
lowing variety: 
Var. perplexa: acheniis biaristatis pubescentibus. — TExas: 
valleys in the mountains east of El Paso, May—Oct. 1849, Wright 
331 p.p. (TyPE in hb. Kew, fragments and tracing in Gray Herb.). 
All other specimens of this number examined (Gray Herb., Brit. 
Mus., U.S. Nat. Herb.) have the glabrous calvous achene of var. 
epapposa. Although by the key given in my revision this new 
variety would be referred to S. lagascaeformis DC., yet it differs 
from that species and agrees with S. exaristata in the few small 
characters — longer narrower phyllaries, narrower pales, longer 
disk-florets, fewer larger heads, and leaves not at all glandular 
beneath — which in addition to the usual achenial differences 
serve to distinguish the latter species from its close ally S. lagascae- 
formis. Were it not for the rather striking gap in their ranges — 
which however Botteri 804 (Gray Herb.) from Orizaba, which is 
S. exaristata, and Bourgeau 3320 (hb. Kew) from Orizaba, Nov. 
1866, with Gouin (hb. Paris) from the state of Vera Cruz, 8 Nov. 
1866, both of which are S. lagascaeformis, show is not an absolute 
one — §. exaristata might require reduction as a variety to S. 
lagascaeformis. 
Smusia FortTrpa (Cav.) Blake, Proc. Am. Acad. xlix. 385 (1913). 
— An authentic specimen from Pavon (in the Prodromus Herba- 
rium at Geneva) of Cavanilles’s Coreopsis foetida, on which the 
name Simsia foetida was based, is not that species as interpreted 
In my revision but is identical with S. adenophora (Greenm.) Blake, 
l. c. 388. The name Simsta ForTIDA must accordingly be used for 
the latter species, and to it should be referred the synonyms Core- 
opsis foetida Cav., Ximenesia foetida Spreng., Encelia foetida 
Hemsl., and Simsia ficifolia Pers. quoted on page 386 of my treat-
