the corolla, composed of 15 to 18 linear-lanceolate hyaline palese (which are broader 

 than in H. Wislizeni), with a very strong hispid midrib, produced at the apex into 

 a short hispid-barbellate awn. The aspect of the heads in fruit is something like 

 those of Petalostemon corymbosura. 



Galinsoga parviflora, Cav., var. Caracasana. Vargasia Caracasana, DC. 

 Prodr. 5. p. 676. Valley of Coppermine Creek, New Mexico; Aug., Oct. (1267.) 

 — The achenia of the ray are slighly hairy near the summit, and furnished with a 

 very small setiform pappus, as De Candolle characterized Vargasia, much more 

 reduced than in the figure in Deless. Ic. Sel. 4. t. 47.

 Pep. p. 144. t. 6. Valleys between Eagle Springs and the Kio Grande; and on the 

 Mimbres; July. Near El Paso, abundant ; April, May. (1269.) 



B. PLENiRADiATA, Harv. 8p Gray, I. c. Valleys west of Chiricahui Mountains, 

 Sonora; Sept. (1270.) 



Achillea Millefolium, 2/«?m. Mountain ravine near the Mimbres ; Oct. (1271.) 

 Artemisia dracunculoides, Pursh. ; Gray, PI. Wright, p. 124. Hills, around 

 the copper mines, New Mexico; Oct. (1272.) 



A. FiLiFOLiA, Torr. Valley of Coppermine Creek; Oct. (1273.) 

 A. Canadensis, Michx. ; Torr. ^ Gray, Fl. 2. p. 417. Hills and valleys around 

 the copper mines; Aug., in flower; Oct., in fruit. (1274.) — A form with the 

 radical leaves canescent. 



A. LuDOViciANA, Nutt. ; Torr. Sc Gray, I. c. Side of mountains at the copper- 

 mines ; Oct. Also on mountains near Conde's Camp ; Sept. (1275.) Also a small- 

 leaved and very canescent form, like Wright's No. 391. (1276.) 



A. LuDoviciANA, var. foliis lobisve lineari-lanceolatis supra glabratis. — Valleys 

 near the copper mines; Oct. (1277.) — A form resembling Lindheimer's No. 442, 

 and approaching that called A. Mexicana. 



A. LuDoviciANA, var. Mexicana, forma tenuifolia. — Mountains around the cop- 

 per mines ; Oct. (1278.) — Lobes of the leaves finer, and the involucre less pubes- 

 cent, than in Lindheimer's No. 444, which I cannot specifically distinguish from A. 

 Ludoviciana. — Collected with the above is a plant with similar and canescent 

 leaves on the sterile shoots ; but those of the fertile stems glabrate, pinnately 3 

 5-parted, with the lobes and rhachis nearly filiform. (1279.) 



Gnaphalium palustre, Nutt. ; Torr. ^ Gray, Fl. 2. p. 427. Sandy banks of 

 the Rio Grande above El Paso; July. (1280.) 



* The following is a New Mexican representative of a Californian and Oregon genus : — 

 Layia (Madaroglossa) Neo-Mexicana (sp. nov.) : hispida, parce glandulosa; foliis linearibus inte- 

 gerrimis ; Jigulis trifidis albis ; acheniis radii pappo parvo paleaceo subdimidiato laciniato coronatis, disci 

 parce pilosis ; cast, fere L. glandulosse. — Near Santa Barbara, New Mexico, Aug., Dr. J. M. Bigelow. 

 (Communicated by Dr. Torrey.) — This might, perhaps, have been taken for Layia glandulosa, if it were 

 not for the constant presence of a pappus in the ray-flowers ; in which respect it differs not only from 

 the rest of the genus, but from the sole distinguishing character of the division Madiecs. The character 

 of the genus and of the section Madaroglossa must accordingly be extended in this particular.
