152 BOTANY. 



Aster* ericefolius, Rothrock (in Botanical Gazette, Jan., 1877). — 

 Willow Spring, Arizona (208) ; Santa Fe\ N. Mex. (14). 



Erigekon Canadense, L. — Central Arizona (718, 764). 



Erigeron composititm, Pursh — Colorado (493); also var. discoideus, 

 Gray, from Utah. Number 49(1 from Colorado is a form near E. pedatum, 

 Nutt., but still somewhat hirsute, and the leaves and petioles distinctly 

 hispidly ciliate, and the involucre as hairy as the typical E compositum. 



Erigeron grandiflorum, Hook., var. elatius, Gray (Enum. PI. Par- 

 ry). — A foot or more high, with several heads ; stems leafy almost to the 

 summit ; scales of the involucre with extremely delicate tips, and united 

 into a woolly mass. — Mosquito Pass, Colorado (487, 490). 



Erigeron ursinum, D. C. Eaton (in vol. V, King's Survey, p. 148). — 

 (495.) 



Erigeron uniflorum, L., var. — 4-10' high, more or less pubescent, a 

 single head terminating the erect, sparsely leaved stem ; lower leaves spatu- 

 late-oblong, tapering to a hispidly ciliate petiole; stem-leaves oblanceolate, 

 sessile; scales of the involucre somewhat crowded, hairy, and usually with 

 purple, tapering tips; rays about fiO, purple, twice as long as the disk- 

 flowers (achenia too young); pappus almost uniform and a. little shorter 



* " Dipi.opappus ericoides, T. & G. — To save labor to some others who, like myself, work under 

 the double disadvantage of a rather limited library and an herbarium (rich enough in the later new species) 

 with but few specimens from the origiual sets made prior to 1862, I put the following in print. From 

 our present standpoint it is evident that Diplopappus as formerly understood must be partitioned out 

 among other neighboring genera, and of the species that concern us here, one goes to section Ericame- 

 eia. of Aplopappus, and the other to section Orthomeris of Aster. In the unavoidable changiug of 

 names a confusion arises under the name above given, i. e., Diplopappus ericoides, there being two plants 

 that bear the name in herbaria and books. The following may in some sense clear up the matter: 



Diplopappus ericoides, T. & G. Eucephalus ericoi- 

 des, Nutt. "Inula? ericoides, Torr. I in Ann. Lye. 

 New York, 2, p. 212. Chrysopsis ericoides, EatoD, 

 Man. Bot." 



Now placed in Aster under Sect. Okthomeris. 

 As the name ericoides is preoccupied in this genus 

 I suggest for it Aster criccefoliiis, which indicates 

 even more closely its general habit. 



See also Diplopappus ericoides, T. & G., Vol. V., 

 King's Report; PI. Wright., p. 78; PI. Fend]., p. 

 69 ; Bot. Mex. Bound., p. 78. 



The two plants are so different in habit, — the one suggestive of (so far as arrangement of the 

 foliage goes) Erica, and the other of Adenostoma fasciculatum, Hook. & Am., or of Eriogonum fascicu- 

 latum, Beuth.— as well as in habitat, that any further description is unnecessary." — Botanical Gazette, 

 Januarv, 1877. 



Diplopappus ericoides, Less. Aplopappus ericoides, 

 DC., and apparently also of Hooker and Arnott. 

 See DC., Prod. V., p. 278; Bot. Beechy, p. 146; and 

 Fl. Cal. I., p. 313. 



In the last, Ericameria microphylla, Nutt., is also 

 cited as another name for the name, and by this it 

 appears in Flora of North America, T. & G., 2, p. 

 236.
