Notes. 



34. Since I then did not have access to the descriptions of the species into 

 which Hooker's plant has been broken up, and did not preserve material enough 

 to justify any such separation now, the old name is here allowed to stand. 



106. The specimen of the grape I have so called, was gathered in fruit, Sept. 30, 

 1898, in a fence-row. It differs from all specimens of Vitis riparia, Mx., that I have 

 seen, in its narrower acute to acutish sinus. The leaves are long acuminate, 

 slightly 3-lobed, and coarsely toothed. Seeds large with distinct rhaphe. Berries 

 blue-black with bloom — sour, in this respect like V riparia, Mx.; but the color 

 of the fruit is no indubitable criterion. It is not uncommon to find true V. riparia, 

 Mx. with jet black fruit, and, as is well known, the flavor of these species become 

 sourer as they are found farther from the coast. I have carefully measured the 

 sinuses of all specimens that I have, with the following result: Specimen of V. 

 riparia, Mx., McCords, Mich., Aug. 6, 1899, bottoms of Thornapple river, outer 

 width of sinus 1V4-1% inches; inner width ^-114 in.; specimen of V. riparia, Mx., 

 Manistee, Mich., Jime, 1900, in flower (leaves immature), banks of Lake Michigan, 

 outer width %-lVi in; inner width V2-% in.; specimen of V. riparia, Mx., Ionia, 

 Mich., May 1896, in flower (leaves immature), thicket, outer width 1-1 1^ in.; inner 

 width y2 in.; specimen of V. cordifolia, Mx., Sturgis, Mich., Sept. 30, 1898, fence- 

 row, outer width V^-% in.; inner width 1-16-% in. The Ionia specimen has a less 

 rounded sinus than the others mentioned of V. riparia. Mx., and was pronounced 

 V. cordifolia, Mx. at Harvard. 



130. This rose, gathered on a lake border, Sept. 1898, has stout curved spines 

 and, ver/ numerous slender prickles; stipules narrow, dilated at summit; flower 

 solitary; leaflets seven, sharply serrate. It resembles Rosa nitida, Willd. very 

 much, but its spines are curved instead of straight, in which respect it differs 

 also from R. humilis, Marsh. These three species are very closely related, and 

 an examination of a very large number of specimens would be necessary to prove 

 that the distinction based on the spines will in all cases hold good. 



409. A form of this without rays was found, a hybrid apparently with Bidens 

 frondosa, L.
