NOTES ON THE WILLOWS OF THE CHILLIWACK VALLEY, B.C. i I By J. M. Mac'OI N. The number of species of Salix in the Chilliwack Valley is remarkably small for that region, only four species having been seen in 1901 in the valley itscU and five on the mountains on either side of it. In the valley .9. Si/c/iens/s is common everwhere, and was the only willow growing along the river between Chilliwack Lake and the point at which the river enters the Eraser Valley with the exception of one clump of S. pscudomyrsinites Anders., which grew on a gravel bar in the river This species was also found by a rivulet at an altitude of 6,000 feet. The other valley species were S. camlata {^nX.\..), collected at Chilliwack village, and S. Lyallii, Heller, at Sumas Lake and by a stream flowing into Chilliwack Lake. ?76 The Ottawa Naturalist. [March The only common species on the mountains was S. comi)iiitaiti, Bebb., always by rivulets at about 5,000 feet altitude, where snow has lain late in the sprinj;'. S. coiijunctu, Bebb., was found on one mountain in a similiar habitat. .S\ nivalis. Hook., which mig'ht be expected to be common, was seen only on Tami Hy Mountain at an altitude of 5,500 feet. S. siibconiuia covered a large boulder at 5,600 feet and S. cnissi/'iilis, Trautv , was abun- dant on a rocky slope on Tami Hy Mt. but seen nowhere else. Specimens ot all the abpve were examined by Dr. P. A. Rydberg who has verified my determinations and named the species about which I was uncertain. TARAXACUM IN CANADA. About a year ago Dr. Edw. L. Greene described several new species of Taraxacum from Canada.* Several sheets of specimens have been added to the Geological Survey collection since our material was examined by-.Dr. Greene, but these are all referrable to one or other of the species enumerated below. In his intro- ductory note Dr. Greene says : " Indigenous species will probably be found sufficiently numerous thougb perhaps only upon western mountain territory." It is probably true that the number of in- digenous species in eastern and northeastern Canada is small, perhaps, indeed, there is only one species which ranges from the mountains if eastern Quebec through Labrador and Ungava to Hudson B y, but that there is at least one indigenous species in eastern Canada no one who has travelled through the unsettled 'Piltoni.-i, Vol. IV, pp. 227-233. ■W'W wmmmmm mmm «PIHP1 1 902 J Macoun— Taraxacum in Canada. 277 parts of the country ciin doubt.

Stems about two feet high, very erect, divested of all lower leaves at flowering time, parted from below the middle into numerous leafy and flowering branches forming a somewhat contracted and subpyramidal panicle ; the reddened bark of stem and branches glabrous or obscurely pubes- cent : leaves ot the panicle narrowly lance-linear, two inches long more or less, entire, sessile by a broad more or less perceptibly auricled base, thin, delicately scaberulous above, scabrous on the margin, glabrous beneath, marked by a delicate midnerve only, spreading or slightly Jeflexed : heads few and subracemose on the M. nches, or solitary at the ends of them, nearly an inch broad measuring the rays, the involucre short-canjpanulate, its bracts in about three series, narrowly spatulate lanceolate, scaberulous, at least marginally, and spreading or recurved at tip : rays many and showy, apparently pale violet. The types of this strikingly handsome new Aster are Mr. Macoun's numbers 26,3^>4 and 26,385 from the Chilliwack Valley, B.C., collected 18 Aug., igoi. Tts immediate allies are A. longi- foliusy Lam., A. hespcrius, Gray, and A. eiisatits, Greene. From all of these it diff^ers not only in aspect, but in its foliage which, though sensibly roughened above, is yet of a texture so delicate that all the lower and properly cauline ones fade and fall before the time of flowering. It is perhaps more elegant and beautiful than any of its near te4-ations, and ratJier smaller in stature, though growing in generous soil, and a climate abundantly moist and not severe. Gnaphalium macounii. Apparently biennial, the stems rigidly erect, about two feet high, rather loosely leafy and clothed with a somewhat hirsute and viscid glandular-pubescence : leaves narrowly oblanceolate, acute, 3 inches long, the upper decurrent, all white-woolly beneath, light green and merely glandular-pubes- cent above : branches ot the subpyramidal close panicle and the main stem for some distance below it densely white-woolly : invol- ucres of middle size, their pearly scarious brads all ovate, very acute : flower and fruit not seen. r902| Greene — Some New Northwestern Composit.e. 279 ColIecteLl in the Chillivvack Valley, B.C., 29 July, by Mr. Jas.

Annual, erect, rather slender, a foot high, rather amply leafy, even up to the subsessile leafy-bracted clusters of heads : leaves thin, equally hoary ou both faces, about i]4 indies long, from ovate-lanceolate to oblong-lanceolate, broadest at the sessile and subcordate-clasping base, somewhat cuspidately acute : small plants simple and with hut a terminal cyme ; hi-'crer ones with many short but strict branches, each with its cyme : bracts of the rather smallish involucres j^reenish-white, the outer broadly triangular lanceolate and acute, the inner very obtuse : pappus rather scanty, dull-white. In moist ground in the vicinity of the Mammoth Hot Springs, Yellowstone Park, Messrs. A. and E. Nelson, 1899, distributed under No. 6,036 for G. Spreugelii, from which the species differs widely in habit, form of foliage, etc. Arnica l.kvigata. Near A. la ti folia and as large, the herbage of a deeper green and of much more thin and delicate texture : radical leaves from round-ovate aud cordate to lance- ovate, and subcordate, 2 "t6"3 inches long, on slender' petioles as long, the 2 or 3 cauline pairs broad and sessile, glabrous on both faces and coarsely, incisely, often doubly serrate-toothed, the larger 3 inches long and more than 2 in breadth : peduncles about 3, slender, puberulent under their narrowly turbinate in- volucres, the bracts ot these uniserial, lanceolate, acuminate, scarcely pubescent except as to the villous-ciliolate margins ; rays light-yellow, long and narrow ; disk-corollas narrow-fnnnelform, the very short and i.irtellous tube passing gradually into the limb, which much exceeds it in length : pappus white ; achenes glabrous. 28o The Ottawa Naturalist. [March By sprinji^s in woods of the Chilliwack Valley, B.C., 5 Aug., 1901, J. M. Macoun, No. 26,926. However much like A. latijolia in general habit and leal-outline this may be, it must needs be dis- tinguished sprcifically by its total lack ot pubescence, thin texture, narrow involucres, funnelform corollas, etc. in true A. hitifolia the bracts are glandular-hairy throughout, and not at all ciliate ; and its disk-corollas are much larger and not funnelform, the throat and limb swelling out abruptly from the short tube. Mr. Macoun writes that this species was collected in 1901 on Mt. Cheam by Mr. J. R. Anderson and Dr. Jas. Fletcher. Arnica aprica. Also akin to A. lati folia and like it com- monly more or less pubescent, but the hairs less rigid, and obviously jointed ; the whole plant much smaller in all its parts, and the heads more numerous : radical leaves long-petioled and broadly or narrowly cordate-ovate, the cauline oval, sessile, all serrate or dentate, the teeth callous-tipped : bracts of turbinate involucre few, thin, oblanceolate, acute or acuminate, often purple- tipped, nearly glabrous : rays few, rather deep-yellow, not deeply toothed, the teeth short and broad : disk-ccrollas with slender tube about as long as the subcylindric but abrupt limb : pappus firm, white ; achenes long and slender, glabrous except a few obscure bristly very short hairs and as few minute glands about the summit. This is represent.:.! by Mr. James Macoun's numbers 26,284 and 26,285 from the Chilliwack Valley. It is said to be a plant not of the woods, but of open ground along streamlets. It is readily distinguishable from A. latifolia not only by its smaller size and more numerous flowers, but by the character of its pubescence, and especially by its short merely tridentate rays ; these last, in the real A, lafijolia, being elongated, and very deeply cut at summit into narrow almost ligulate teeth or seg- ments. Arnica Macounii. Greene, Pitt, iv., 160. This species, hitherto known to me only from Vancouver Island, was copiously collected by Mr. James Macoun in the Chilliwack Valley, last season, the specimens bearing the numbers 26,927, 26,928 and 26,929 of the Geol. Surv. Herb. 1902] GRliliNIi — SOMK NkW NoKTHWESTIiKN C'OMPOSIT.K. 28 1 Arnica aurantiaca, Greene, Torreya i, 42, founded on a plant of Orej^on collected only by Mr. Cusick until now, must be credited to Hritish Columbia, Mr. Macoun's No. 26,934 from the Chillivvack reji;ion matching' perfectly the originals of the species. Arnica conkinis. Less than a foot I'igh, monocephalous, or else with also a pair of monocephalous peduncles from the axils of the uppermost pair of leaves, these surpassing- the terminal one ; herbage of a light green, viscid-puberulent as to the foliage, the stem with a sparse hairiness : lowest leaves obovatc to oblanceo- late, an inch long or more and petiolate, the cauline in about three pairs, ovate to lanceolate, i to 2 inches long, callous-denticulate, or serrate-dentate, or even subentire, acutish : heads of middle size, the involucral bracts biserial, acuminate, sparsely hirsute : rays deep-yellow, not larg^e ; disk-corollas with hirsute tube and naked limb about equal ; achene.-> with a few hirsute hairs ; pappus tawny, subplumose. Chilliwack V^alley, B.C., Mr. Macoun, No. 26,933. In characters of pubescence, (lower and fruit this approaches A. ova/u, Greene, but in toiiag-e and habit it differs widely. Arnija asi'era. Stems clustered, often 2 feet high, equably leafy to the corymbose summit, loosely hirsute, more strong-ly and quite retrorsely so toward the base : leaves about 2 inches long", ovate-lanceolate, sessile by a broad base, the upper long-er, the lower shorter than the internodes, roug-h-hairy on both faces, saliently callous dentate : peduncles several, slender ; involucres small for the plant, can^panulate, their bracts uniserial, hispidulous with pustulate hairs ; rays very obtuse and only minutely triden- tate ; disk-corollas with very short tube and rather longer limb about equally and very sparsely setose-hairy : achenes setose- hairy; pappus tawny, subplumose. The type of this species is a plant found by myself on Mt. Rainier, 19 .Aug., 1889, and then supposed to be A. amplexiciiiilis^ which I have vc^w for some time known to be a very different plant. A. aspeni has also been collected by Mr. Piper at Snoqualmie Falls, Washington, and again in the Olympic Moun- tains. Mr. M. W. Cior:nan obtained it in 1897 among his plants of the Washington Foiest Reserve. 282 The Ottawa Naturalist. [March Arnica cana is a name needed to replace that of A. incann, Greene, Pitt., iv, 169; there being an Arnica incana ot Persoon of much earlier date. Arnka crocina, Greene, Torreya, i. 42, first published in Piitonia, iv,- 159, by the untenable name of A. croceu, is now in hand from two additional stations. It is Mr. James Macoun's No. 26,931 from dry slopes north of Chilliwack Lake, 26th July, 1901 ; also No. 34,074 of the Canad. Geol. Surv., collected by J. R. Anderson, 1901, from Mt.
