HiB. Point Levy, Canada. Mrs Sheppard. Newfoundland and Labrador. Dr Morison. N.W.Coast,

Brenton._The.remote but large and strong teeth in our var. bring the state of the plant near P. Coronopus,
of which it may be a var.
6. P. pauciflora (Ph. Am. 1. p. 99); foliis lineari-lanceolatis integerrimis glabriusculis,
scapo terpti foliis breviore, spica pauciflora interrupta, bracteis ovatis acutis glabiis.
P. elongata. Ph. Suppl 11. p. 729 (according to Nutt.).
H a b . Labrador (P h . ) but I have great doubts about this plant. The original P. elongata, gathered by
Bradbruy in Upper Louisiana, which Nuttall pronounces to be the same with P. pauciflora, is identical with
pusilla, which I have never seen from British N. America, and I should think is a very unlikely inhabitant
of Labrador.
7. P. gnaphalioides (Nutt. Gen. Am. 1. p. 100);' totalonge sericeo-villosa, foliis lineari-
lanceolatis acutissimis, spica elongata cylindrica densiflora, staminibus inclusis, capsula
biloculari disperma.— P. Lagopus. Ph. {non Linn.)—13. bracteis longissimis spinulosis.— P.
aristata. Mx.
Hab. N. W. America. Menzies (in Herb, nostr.). Common on the barren plains of the Columbia.
Douglas.— The Columbia is probably the northern limit of this fine species. It is an inhabitant of the
Southern United States. Mr Nuttall gathered it in Arkansa ; Mr Drummond at San Felipe m Texas ( O'-
HL n. 854) ; and the var. aristata in the same place (Colt. III. n. 358). Mr Nuttall has proved that the
P. aristata is only an accidental var. of bis P. gnaphalioides.

Hab. About Carlton House Fort on the Saskatchewan. IJnimmunA-Bradbury (from Shom- there is
an authentic specimen in my herbarium) discovered this plant in Upper Louisiana. The present inhabits
much more northern station! the most northerly perhaps of any of the genus ; of which thespec.es are more,
frequent in the south.

River, very frequent. Tolmie.—A particularly, variable plant, perhaps too nearly allied to the following, with
which it agrees in the colour of the flowers, but differs in the foliage; this latter again exactly resembles that
of A. umbellata (Ex. FI. t. 194), differing little but in the yellowish-white and downy, not red and glabrous,
flowers.
