Rosa acicularis’x< blanda. Rosa blanda glandulosa Schuette, Proc. Am. Assoc. Adv. Sci. 46: 
279. 1898 (aslightly glandular form). ‘This hybrid resembles R. blanda in habit and leaf-form, the 
leaflets being inclined to be obovate and rounded at the apex; but the fruit is more like R. acicularis, 
being ellipsoid or pear-shaped, with a neck; the pubescence of the leaves beneath is longer than in the 
former and finer than in the latter. Along Lake Michigan, near Chesterton, Indiana, August 22, 
1915, C. C. Deam 18002. Indiana to Wisconsin. 
Rosa blanda X virginiana. This resembles R. blanda in habit, having the young shoots 
bristly and the branches unarmed, and the pubescent leaves of that species, but the inflorescence 
is more corymbose, the pedicels and hypanthium have occasionally glandular hairs and the leaflets 
are firmer, dark-green and shining above as in R. virginiana. It lacks the stout prickles of that 
species. Point Abino, on Lake Erie, Ontario, August 28, 1896, J. K. Small. 
55. Rosa anacantha Greene, Leaflets 2: 265. 1912.

rarely with a few small straight prickles; leaflets rather firm, oval, 1.5—3 cm. long, pale and 
dull on both sides, minutely puberulent or glabrate above, somewhat paler and densely puberu- 
lent beneath; flowers corymbose, leafy-bracted; hypanthium glabrous, subglobose, in fruit 
8—10 mm. in diameter; sepals densely puberulent, not glandular, lanceolate, caudate-attenuate, 
15-20 mm. long, erect and persistent in fruit; styles distinct, not exserted, persistent; achenes 
inserted both in the bottom and on the sides of the hypanthium.
