H ab. Canada. Pursh.—/3. About the Saskatchewan. Drummond.—The true H. venosum, with broader
leaves and coloured veins, (such as I have received from Dr. Boott, gathered near Boston,) I have never seen
from the British Possessions. But my var. /3.1 have reason to think is not specifically distinct from it. I
must however, state, that, from the varied appearances assumed by the North American Hieracia, I fear they
are nearly as difficult of determination as those of Europe.
3. H. gracile ; scapo nudo seu monophyllo glabro superne cymoso-racemoso pubescente
involucrisque nigro-pilosis subglandulosis, foliis oblongis obtusiusculis glabris in petiolum
longiusculum attenuatis membranaceis integerrimis, floribus parvis.
Hab. On the more elevated Rocky Mountains. Drummond.—12-18 inches high, slender, and with a
good deal the habit of H. venosum; but the foliage is different, the panicle is reduced to a raceme, whose
lower pedicels are considerably elongated, and they, in their upper part, and the involucres, are clothed
with long black hairs, mixed with some pedicellated glands.
4. H. olbiflorum; caule folioso inferne molliter deflexo-piloso, foliis lato-lanceolatis
integerrimis obtusis in petiolum attenuatis longe albo-pilosis, caulinis remotiusculis sensim
minoribus sessilibus, panicula gracili multiflora glabra, pedicellis divaricatis, involucris pilis
longis albidis sparsis, “ floribus albis.”
Hab, Alpine woods in the Rocky Mountains, north of the Smoking River, in lat. 56°. Drummond.—
This has somewhat the habit of H. Gronovii, but it is very different in other particulars. The leaves are
clothed with long, shaggy, very soft white hairs, which are copious, and remarkably deflexed on the
petioles and base of the stem; while the rest of the stem and the panicle are glabrous, and. the involucre has
only a few long, scattered, patent hairs.
5. H. Scouleri ; setoso-pilosum, pilis longis rigidis patentibus fuscescentibus, caule folioso
paniculato, panicula ampla multiflora ramis erectis, foliis lato-lanceolatis subcoriaceis rigidis
acutis vix dentatis, radicalibus in petiolum brevem attenuatis, caulinis remotiusculis sessilibus,
involucris fuscescenti-pubescentibus pube pilis longiusculis glandulosis immixto.
Hab. At the mouth of the Columbia. Dr. Scouler.—A remarkable and distinct species; in its very
long coarse rigid hairs allied to H. echioides of Waldstein and Kitaibel, and to a very singular species from
River St. Clair, United States, (H. longipilum, of Torrey, in Herb. Nostr. ;) but there the hairs are nearly an
inch long, and remarkably upright and appressed. I possess our present plant also from Dr. Schweinitz,
gathered in Pennsylvania.
6. H. Gronovii; caule folioso, infeme prsecipue patentim piloso superne paniculato,
panicula subcompacta, foliis lato-seu obovato-lanceolatis rigide appressim pilosis integerrimis
obtusis, inferioribus radicalibusque sublonge petiolatis, caulinis remotis sessilibus sensim
minoribus, pedicellis involucrisque pube pilisque glandulosis tectis.—Linn. Sp. PI. p. 1127.

Hab. Canada. Michaux. Pursh. Mrs. Sheppard. Mrs. Percival. Lake Huron. Dr. Todd.—From
various parts of the United States I have received two states of this species: the one (a.) a slender plant,
with few and distant and narrower leaves on the stem, and more petiolated radical ones; and (/3.), a much
stouter plant, with broader and more numerous leaves, and larger and more spreading panicles. The latter
is the H. scabrum of Dr. Darlington, and probably of Michaux and other authors. Pursh refers the H.
Marianum of Willd. to the present species, and correctly so, if 1 may judge by Dr. Schweinitz’ specimens.
I infer that our plant is the H. Marianum of Bigelow, for his description agrees with it, and Dr. Boott’s
specimens, from Boston, compared with and named “ H. Gronovii of Michaux’s Herbarium,” have also, for
synonym, H. Marianum, Willd.
