from Greenland and from Kamtschatka, which differ in no respect from those in Capt. Beechey’s collection.
The plant is still slenderer than A. propinqua. As is the case with that species, Chamisso and Schlechtendal
notice two vars., the one glabrous, the other pubescent.

Franklin and Capt. Back. Kotzebue’s Sound. Lay and Collie in Capt. Beechey’s Voyage. <y. Coast, west
of the Mackenzie River. Dr. Richardson.—This very fine species seems peculiarly to merit the name of
arctica. Mr. Drummond did not meet with it upon the Rocky Mountains: but in more southern latitudes
the A. obtusa of Dr. Torrey is found on the higher parts of the same range, and both from a specimen in
my Herbarium, and from that Author’s own remarks, (See Torrey’s Account o f Plants from the Rocky
Mountains, p. 170,) it is very nearly allied to, if not the same as, the present.

Hab. North-West Coast of America. Nelson in Herb. Banks. (Pursh.) Chamisso’s Island and Island
of St. Lawrence. Chamisso.—I have placed this next to A. arctica, because, judging from Pursh’s description,
it must be nearly allied to it. Chamisso, however,.keeps it distinct; but says, that in the Bay of St.
Lawrence (on the Asiatic side of Behring’s Straits) he found a plant that was intermediate between
the two in question. The chief distinction from A. arctica, appears to me to be in the capsule, which Pursh
says is thrice as long as the calyx.
14. A. fasciculata; (?) “ glabriuscula, caespitosa, cauliculis stricto-erectis, foliis subu-
latis pungentibus striatis, floribus dense fasciculatis, calycibus subulatis striatis, petalis
brevissimis.”—Pursh, FI. Am. v. 1. p. 319.
Hab. Canada; in Mr. Lambert’s Herbarium from Kew Gardens. (Pursh.)—This plant must be considered
very doubtful. The true A. fasciculata of Gouan is perhaps one of the rarest of all plants. His
Herbarium in my possession proves it to be quite distinct from the plant so named and figured by Jacquin,
(Austr.p. 182,) which is the A.fastigiata of Smith. The Canadian plant Mr. Pursh alludes to, can scarcely
be the following, which indeed comes nearer to the true A. fasciculata than any other species, inhabiting,
however, a’widely different part of America, which was a terra incognita at the time Mr. Pursh wrote.
15. A. Franklinii ; ramis erectis fastigiatis numerosis fragilibus, foliis nitidissimis subu-
lato-setaceis, floribus fasciculatis, sepalis subulatis scariosis late uninerviis petala lineari-
oblonga superantibus. (Tab. XXXV.)—A. Franklinii. Douglas, MSS.
Radix sublonga, descendens, perennis. Caules breves, foliorum vetustorum vestigiis obsiti, in ramos nu-
merosos, erectos, subpalmares, basin versus divisi. Rami valde fragiles, glabri. Folia opposita, basi connata,
vix unciam longa, subulato-setacea, erecta, nitidissima, albescentia, obscure uninervia, integerrima vel sub
summa lente minute ciliato-dentata. Flores terminales, dense fastigiati. Pedunculi breves, foliosi seu bracteati.
Bractea foliis similes, sed paulo minores magisque scariosse. Sepala semiunciam longa, subulata seu lanceolato-
subulata, acuminatissima, membranacea, scariosa, albida, dorso nervo latiusculo obscure viridi notata, margine
nunc integerrima, nunc, ut in foliis, minutissime ciliata. Petala oblonga, obtusissima, basi attenuata, calyce
breviora. Siam. 10, vix petala aequantia. Germen ovale. Styli 3. Capsula ovali-rotundata, calyce multo
brevior, apice 3-valvis, valvis medio bifidis.
Hab. Abundant on barren sandy plains and undulating grounds of the Columbia, from the “ Great ” to
the “ Kettle Falls;” and south of that river as far as the source of the Missouri. Douglas.—This is the most
beautiful, and, at the same time, the most distinct of the genus, remarkable for its fragile stems, and glossy
foliage and calyces. Its nearest affinity is assuredly the A. fasciculata of Gouan; but that is at once
recognized by its decidedly annual root, its coarser, rigid, and more opaque aspect, and, above all, by the
leaves and sepals being strongly 3- or 5-ribbed.
