(3058.) R. circinatus, Sibth.; Cray, Man., ed. VI., 40 (1890.)
All references under R. hederaceus, Part I., 15, and under R. aquatilis, var. heterophyllus, Part III., 479, belong here. Quite common in many parts of Vancouver Island, especially at Cedar Hill, Goldstream, Nanaimo, and Salt Spring Island, Gulf of Georgia; also at Agas;uz and by a pond on the mountain south of Spence's Bridge, B.C., 1889. (Macoun.) True R. hederaceus has been collected by the Rev. A. Waghorne on Newfoundland.
(29.) R. multifidus, Pursh, var. terrestris, Gray, Man., ed. VI., 41 (1890.)
References under R. multifidus, Pursh, var. ß. Part I., 16, belong here. On mud, Bonaparte River, B.C. (J. M. Macoun.) Shore of Griffin Lake, B.C. (Macoun.)
R. Flammula, Linn., var. reptans, Meyer; Macoun, Cat., I., 17.
We agree with Dr. Britton in going back to the old name for this species and hence would place all our specimens of R. Flammula var. reptans under this name.
(31.) R. Flammula, Linn., var. intermedius, Hook. Fl. I., 11.
Gravelly or muddy margins of streams. Donald, Columbia Valley, 1885; Griffin Lake, Gold Range; Kamloops, Agassiz, Port Haney, Hastings, and Lulu Island, B.C., 1889; also frequent on Vancouver Island. 1887. (Macoun.)
(3060.) R. natans, C. E. Meyer.
To this species must be referred all the specimens included in R. multifidus, var. γ. repens, Part I., 16, & III., 480. Albion Road, Prince Edward Island, 1888; Bonaparte River, and Griffin Lake, Gold Range, B.C., 1889. (Macoun.)
(3061.) R. Eschscholtzii, Schlecht. Hook. Fl. I., 18.
All references under R. nivalis var. Eschscholtzii, Watson, Part L, 20, & III., 480, belong here. Common on Mount Queest, and other summits of the Gold Range, B.C., at an altitude of 5000 to 7000 feet, 1889. (Macoun.)
(3062.) R. aeriform is, Gray, Proced. Amer. Acad., XIII., 374.
B. acris, Hook. Fl. L, 18, in part.
"A foot high, strict, with pubescence in good part appressed; leaves all palmately or pedately and deeply 3-5 parted or even divided, and often again 2-3 cleft into narrow lanceolate or linear segments or lobes; petals orbicular-obovate, one-fourth inch long, hardly double the length of the spreading calyx; akenes over a line long; beak of half their length." Northern Rocky Mountains, Lat. 58°. (Drummond vide Gray.)
(3063.) R. hispidus, Michx.; partly DC.
B. repens, Linn., var. hispidus, Torr. & Gray; Macoun, Cat. I., 21.
All the specimens of our native forms referred to R. repens var. hispidus, belong here, or to the next. Dr. Cray in his last revision placed the species after R. Pennsylvanicus, which is evidently its proper place. At present it is rather difficult to separate specimens of this form from R. septentrionahs, Poir., and it is very desirable that all Canadian collectors get good fruiting specimens of what we formerly included in R. repens and its variety. Our specimens of R. hispidus are as below. Mouth of Nepigon River, Lake Superior; Pheasant Plain, Man.; Red Deer River, near Hand Hills, Alberta; along the Columbia River at Donald; at Kamloops, Agassiz, and Port Haney, B.C. (Macoun.) Wigwam River, B.C. (Dawson.)
(3064.) R. septentrionalis, Poir.; Gray, Man., ed. VI., 43. (1890.)
Nearly all the synonymy placed under R. repens var. hispidus by me in Part I., page 20 of this Catalogue is transferred to this species by Dr. Gray, so that nearly all the localities for the former species may possibly belong to this, which ranges from New Brunswick to Manitoba. Our specimens of it are as below. In low ground along streams, in alluvium. Campbellton, N.B. (Chalmers.) Chipman, N.B. (Wet-more.) Whycocogmah, Cape Breton; Black River, Prince Edward Island; Becscie River, Anticosti; Madeline River, Gaspé, Q.; Cold Creek Valley, near Wooler, Ont. (Macoun.) Vicinity of London, Ont., and var. nitidus, Part I., 22, from London. (Burgess.)
(3065.) R. hebbcarpus, Hook. & Arn.
Introduced in ballast on the wharves at Nanaimo, Vancouver Island. (Macoun.)
(51.) R. occidentalis, Nutt.; Gray, Proced. Amer. Acad., XIII., 372; Macoun, Cat., I., 22.
R. Nelsoni, Gray; Macoun, Cat., I., 22.
Dr. Gray in his late revision takes R. occidentalis as the type of a multiform species and places the following varieties under it.
Var. robustus, Gray, 1. c, 373.
R. occidentalis, Gray, Proced. Amer. Acad., VIII., 374.
A span to a foot or more in height, stout-stemmed and ample-leaved, large flowered. Chiefly Alaskan. (Gray.) Our specimens are from Queen Charlotte Islands, 1878 (Dawson), and Victoria, Vancouver Island, 1887. (Macoun.)
Var. Lyalli, Gray, 1. c.
This variety has rather large thin leaves, short peduncles and petals not longer than the calyx. Valley of Flathead River, Rocky Mountains; mountains, south of Tulameen River, B.C. 1888. (Dawson.) Mountains, north-west of Spence's Bridge, B.C. 1889. (J. M. Macoun.)
Var. tenellus, Gray, 1. c.
R. Nelsoni var. tenellus, Gray; Macoun, Cat., I., 22.
Slender, sometimes tall and with long internodes, often glabrate; leaves simpler and smaller. Common on Vancouver Island and west of the Coast Range, B.C. (Macoun.)
(2099.) E. parvulus, Linn.; Gray, Proced. Amer. Acad., XIII, 378.
R. muricatus, Macoun, Cat., III., 481.
"Akenes smooth and even or at length sprinkled with some scattered papillae, especially towards the margin." In R. muricatus the akenes are strong-beaked, tuberculate or echinate. Only station known St. John's, N.B. (Hay.)
