gracilibus 2 cm longis; stamina petalis duplo longiora; ovaria glabra, 
styli tenues; folliculi ignoti. -- Hab. Among rocks along the ,Link Trail“, 
Manti Nat. Forest, Utah, near Emery. (elev. 2400 m). — Tidestrom. 
— This form, which I at first referred to A. elegantula is distinguished 
from the latter by its uniformly tapering spurs and pink-colored sepals.

Radix ligneus longitudine variabilis, plerumque autem brevis, caudice 
crasso ligneo (uno vel duobus) caules protinus emittente, vel ramis 
plerisque ligneis e superficie superiore caudicis oriundis, qui caules 
singulos usque quaternos gerunt. Caules 1—3 dm. alti, herbacei, scabri, 
in eaudice confertissimi, valde foliosi, praesertim apicem versus. Plantae 
depauperatae paucos tantum et remotos, plantae autem luxuriosae plu- 
rimos et densos caules habent. Folia lineari-lanceolata, in caule 1,5— 
3 cm longa, 2-4 mm lata, in ramis 1,5—2 cm longa, 1 mm lata, minu- 
tatim punctata, margine ciliolata, apice acuto, colore splendido saturate 
viridi et quodammodo flavescente. [Inflorescentia caulem superiorem 
occupans ramosa, foliis minoribus foliosissima, ramis eius terminatis in 
cymo valde contracto, sive plano sive rotundato. Involucra 4,5—5 mm 
alta, cylindrica vel nonnihil turbinata, viscida, summa in 3—4 capitu- 
lorum glomerulis sessilia, lateralia pedunculata. Bracteae involucri in 
3—4 seriebus positae, late lanceolatae, virides vel apicibus viridibus 
pallidae, obtusae vel acuminatae. Flores pallide vel plerumque saturate 
flavi. Flores radiati 4—6, flores discoidei 3—5. — This species belongs 
to the same group as G. diversifolia Greene, and G. scoparia Rydb. The 
former is rather loosely tufted, has an inflorescence of large, turbinate 
involucres in an open and not flat-topped cyme, and 8 or 10 disk- 
flowers. G. scoparia is larger, having stems often 4 dm. in length, and 
its involucres are over 5 mm long and oblong-turbinate. — The plant 
is common in high, dry, sunny prairie soil in central North Dakota, and 
its flowering time is August-September. It is one of the few high 
prairie plants that success-fully resisted the drought of 1910. The type 
was collected at Leeds, North Dakota. 
681. Gutierrezia fulva J. Lunell, l. c., p. 285. — Caules 15—18 cm 
alti, in caudice perenni, ligneo aliquantulum dispersi, fere glabri, angu- 
lati. Folia linearia vel lineari-lanceolata, in caulibus 1—3 cm longa, 
1—2 mm lata, in ramis 0,5 — 1,5 cm longa, filiformia—1 mm lata, colore 
pallide et obscure viridi. Inflorescentia cymum apertum, planum vel 
rotundatum, formans. Involucra 5—6 mm longa, turbinata, lateralia 
longe-pedunculata et saepe simplicia, media in glomerulis 2—4 capitu- 
lorum sessilia vel subsessilia. Bracteae involucri in 3—4 seriebus dispo- 
sitae, ovatae, viridibus, obtusis apicibus pellucidae. Flores fulvi, dis- 
coidei plerumque 5, radiati 6 -8. - The species belongs to the same 
group as G. diversifolia Greene, which has rays 5 or 6, disk-flowers 8 
or 10, G. scoparia Rydb., which is larger in all its parts, has lanceolate 
outer bracts and oblong-turbinate involucres, and G. Greenei, which is 
densely tufted and has a strikingly different color of its foliage, con-
