Egbertville, June 14, 1908 (53222), Oct. 3, 1908 (5677 and 
5612), transplanted and specimens taken Aug. 12, 1909 (5956). 
46. Viola hirsutula x sororia hyb. nov. 
Dark green, pubescent, 2 dm. tall. Leaf-blades broadly ovate, 
obtuse, cordate or somewhat reniform, upper surface appressed- 
pubescent with the characteristic hairs of V. hirsutula, lower sur- 
face pubescent on the veins; margin ciliate, crenate; petioles 
ascending, pubescent, one to three times as long as the blades. 
Cleistogenes not fully developed, small, on prostrate or decumbent 
peduncles; calyx purplish, with short ciliolate auricles. (PLATE 16.) 
This resembles the corresponding cross with V. papilionacea, 
differing chiefly in having pubescent petioles and lower surfaces of 
leaves. A small colony was found in the /” hirsutula patch at 
Egbertville, May 31, 1909 (5682, type), and one plant transferred 
to my garden. 
47. Viola lanceolata x primulifolia hyb. nov. 
Plant taller and more slender than V. primulifolia, and in gen- 
eral appearance intermediate between this and V. /anceolata. Leaf- 
blades ovate to lanceolate, acute or obtuse, decurrent on the petiole, 
margin crenate with low teeth, the points of which are incurved. 
Early flowers on long slender peduncles equal to or longer than 
the petioles; capsules green, about 8 mm. long; seeds brown. 
(PLATE 17.) 
Plants collected at Grasmere, May 29, 1907 (4723, type), and 
some transplanted at home, showed the same intermediate char- 
acter at the end of the season, with a general appearance more 
like V. lanceolata at the end of the season. Other specimens 
were found on South Avenue, June 9, 1907 (4760), transplanted 
and specimens again taken Sept. 29, 1907 (5249); also at Wat- 
chogue, Sept. 20, 1908 (5585), and from transplanted material 
Aug. 6, 1909 (5898). To this hybrid belong probably also: 
Tottenville, Sept. 9, 1868, W. H. Leggett (?); Watchogue, Sept. 30,
