PLANTA FENDLERIAN. 69 
lis, sterilibus patentibus flagelliformibus; foliis spathulatis mucronulatis inferioribus in 
petiolum gracilem attenuatis integris seu radicalibus parce inciso-lobatis, ramealibus par- 
vulis sublinearibus sessilibus ; ligulis numerosis gracilibus (albis purpureo tinctis) involu- 
crum hirsutum duplo superantibus; pappo radii et disci conformi duplici, exteriore coroni- 
formi-squamellato conspicuo, interiore e setis sub-20 fragilibus.— Low, moist places, along 
Santa Fé Creek; May, June. (381.)— Root slender. Flowering stems 5 to 7 inches 
high, very slender, few-leaved below the middle, naked and pedunculiform above; the 
head rather smaller than in the preceding species; the involucre, &c., similar. Lower 
leaves one to two inches long, including the slender petiole; those of the runner-like 
sterile branches decreasing to 2 or 3 lines in length. This species should rank next to 
the foregoing.*

foliis laxis linearibus vel inferioribus spathulatis scabro-glandulosis non strigosis valde 
hispido-ciliatis. — Sides of ravines in arid places, Santa Fé; also on the Rio del Norte: 
May, June. (348.)— A tufted, Heath-like, suffruticose plant, of a span or less in height, 
apparently subject to considerable variation in the foliage; the leaves being sometimes 
all appressed, linear-subulate or acerose, and hoary with appressed. hairs; sometimes less 
hoary, but showing a close glandulosity ; or again (of which the var. 8. exhibits the most 
marked form) with the leaves loose or a little spreading, destitute of appressed hairs, but 
more glandular, and conspicuously fringed with hispid bristles, the longer ones half an 
inch in length, the lowest strictly spatulate. The same species, in one or two forms, 
was gathered in arid places, at Albuquerque, by Dr. Wislizenus, and at Chihuahua and 
Buena Vista by Dr. Gregg. The outer pappus is inconspicuous, and consists of a few 
very slender, short sete. The rays are white, sometimes tinged with purple. — At Buena 
Vista, Dr. Gregg also collected what I take to be a mere variety of this species, with 
“« yellowish ” rays.

Santa Fé, on arid hill-sides, less frequently in grassy places; April, May. (349.) — 
These are fine specimens of the original type of this well-marked genus, with the sessile 
heads fully as large as in Richardson’s and Drummond’s specimens (the larger almost an 
inch in length), and agreeing with them, except that the rays are more fully explanate 
* Erigeron decumbens, Nutt., communicated by Mr. Spalding, from the Kooskooskee, Oregon, has bright 
purplish-blue rays. He also sends E. ochroleucum, Nu/ft., which is the same as no, 203 of Geyer’s Oregon 
collection. No. 30 of the same collection consists, in my set, of E. pumilum, with E. cxspitosum, 8. grandi- 
florum. I mention this, because some transposition or confusion in respect to these numbers must have occur- 
red either in the distribution of the specimens or in the published enumeration.
