and then added the American species without modifying the general 

 diagnosis. 



Ligusticum (Cynapium, Nutt.) apiifolium. Nuttall's two forms, 

 Hall and Harbour's No. 218 from the Rocky Mountains, and the Cal- 

 ifornian specimens (some of them with leafless stems) may comprise 

 two or more species ; but wholly mature fruit has been collected only 

 by Nuttall. In this the seed is scarcely more concave on the face 

 than in some genuine species of Ligusticum, to which genus Bentham 

 and Hooker refer it. 



Ligusticum scopulorum : L. (Gonioselino) Fischeri affine ; mer- 

 icarpiis parum brevioribus ovali-oblongis ; alis angustioribus crassi- 

 oribus, intermediis et dorsali minus evolutis 1-2 sagpe obsoletis ; vittis 

 perspicuis majusculis in valleculis omnibus 3 nunc in lateralibus 4 ; 

 sectione seminum fere reniformi. — Santa Antonita, New Mexico, Dr. 

 J. M. Bigelow, with ripe fruit ; the plant enumerated in the Botany 

 of Whipple's Expedition, p. 38, as Gonioselinum Ganadense. Also in 

 the Rocky Mountains of Colorado Territory, being doubtless Parry's 

 No. 156, and Hall and Harbour's 216 (at least in part), published as 

 G. Fischeri. Apparently the same collected at Fort Steilacombe, 

 Washington Terr., by Dr. Suckley. Fruit in size and shape interme- 

 diate between that of Gonioselinum Fischeri of the Old World, which 

 Bentham and Hooker refer to Ligusticum, and G. Ganadense which 

 (having the vitta? usually solitary in the dorsal and in pairs in the 

 lateral intervals, and the carpels more orbicular) they remand to Seli- 

 num. Unless more definite distinctions can be found, it were better to 

 unite Selinum with Ligusticum. (The Gonioselinum from Ochotsk, in 

 Rodgers's Expedition, mentioned by Bentham and Hooker, is probably 

 the form or doubtful variety cited in the Flora Rossica and Flora 

 Ochotensis under G. cenolophioides.) 



Ligusticum montanum = Thaspium ? montanum, Gray, PI. 

 Fendl., PI. Wright, &c, (referred to Ligusticum by Bentham and 

 Hooker, but by their characters should be a Selinum,) has mericarps in 

 some specimens almost orbicular, including the broad marginal wings, 

 in others oblong-oval ; in both the strong vitta? are sometimes single, 

 sometimes double. The foliage is very variable for one and the same 

 species ; but the form with long and slender divisions to the leaves 

 shows fruit of both shapes. 



Angelica lineariloba : glabra ; caule valido ; petiolis prorsus 

 spathaceo-dilatatis ; foliolis longe linearibus acutatis (1-2-poll.) inte-
