(Ex: Ottawa Naturalist, XVII [1905], pp. 215—216.) 
1. Malus Macounii Greene, l. c., p. 215. 
Tree, 20 feet high, four inches in a diameter; leaves ample, rather 
thin, oval, mostly obtuse, from slightly to conspicuously 3 Jobed, 2 to 
-31/, inches long, 1!/⁄ to 2'/, inches wide, sharply serrate, glabrous on 
both faces even when young; pedicels nearly glabrous and exterior of 
‘calyx wholly so, only the inner face of the acutely triangular reflexed 
lobes tomentulose; corolla large, white; fruit not seen. 
British-Columbia: Margin of Chilliwack Lake, 7 and 13 July, Mr. 
-J. M. Macoun. Thoroughly distinct from M. rivularis by its broad ob- 
tusish thin glabrous 3-lobed foliage, and equally peculiar pedicels and 
-Calyx, 
2. Fragaria latiuscula Greene, 1. c., p. 215. 
Low and not slender, the parts rather firm, peduncles 3 to 6 inches 
high, the leaves nearly as long, both peduncles and petioles villous with 
spreading hairs; leaflets pale, glaucescent and almost glabrous above, 
glaucous and pilose-pubescent beneath; leaflets in the largest leaves not 
very dissimilar, all on uncommonly long petiolules, very broadly cuneate- 
obovate, 1 to 13/, inches long and nearly as broad, those of smaller 
earlier leaves even broader than long, all coarsely deeply and evenly 
crenate; calyx-segments quadrate-oblong, very acute, the elliptic bracteoles 
quite as long; corolla 3/, inch broad, the petals mostly broader than long 
and overlapping; achenes large, superficial.

3. Fragaria retrorsa Greene, l. c., p. 215. 
Slender, soft and delicate woodland plant 6 or 8 inches high; petioles, 
peduncles and pedicels retrorsely long-villous; leaflets light-green above 
and with few scattered hairs, underneath pale and glaucescent as well 
as more hairy, especially along the fine whitish veins, the middle one 
rather acutely obovate-rhomboidal, 1 or 2 inches long, the laterals similar 
but oblique, the teeth of all minutely cuspidate-apiculate; calyx-segments 
almost caudately acuminate; corolla small for plant, about */, inch wide; 
petals round-obovate, not overlapping, dull white, turning red in drying: 
fruits large, subglobose; achenes superficial. 
British-Columbia: Collected in the Chilliwack Valley 1901 by Mr. 
J. M. Macoun and distributed under Geol. Surv. no. 34336. No. 34335 
may be specifically the same, but in this the pubescence is scanty and 
scarcely retrorse; but if habit, foliage and flowers offer here the essential 
marks of a species, the two numbers must bear the same specific name.
