main uncertain until the order is revised. A solitary fruiting specimen in 

 Dr. Parry's collection of 1861 was very carelessly named Leptotcenia dissecta, 

 which is quite a different plant. 214. Musenium trachysfermum, Nutt. ; near 

 M. divaricaium, but the young fruit much shorter as well as more scabrous. 



215. Thaspium trachypleurum, n. sp.,* in fruit, the same as 159 of Parry in 

 1861, of which the fruit was too young. It proves to be quite different from 

 that of T? montanum, var. tenuifolium. The genus is uncertain; but it can 

 hardly be well separated from Thaspium. 217. T. montanum, Gray, PI. 

 Fendi., in flower and in fruit, the latter with the three dorsal wings some- 

 times barely salient, sometimes as much developed as the marginal ones. 



216. Conioselinum Fischeri, Wimm. ; "alpine and subalpine." 218. C. 

 Canadense, Torr. and Gray, probably a larger and coarser form of 216 ; 

 " on low mountains." 219. Arch angelic a Gmelixi, DO. 220. Archemora 

 Fexdleri, Gray, PI. Fendl.; fine, large specimens with good fruit, ''in sub- 

 alpine woods." It is 155 of Parry's 1861 collection, which I carelessly named 

 Berula angustifolia. 221. An acaulescent Umbellifer, undeterminable for the 

 want of fruit. 222. Cymopterus? anisatus, n. sp., called " C. tei;ebinthinus, 

 var. fceniculaceus" in Parry's 1861 collection (No. 157); but it can hardly be 

 either of Nuttall's species under those names, on account of the very long and 

 subulate leaflets of the involucel as well as calyx-teeth, yet apparently rela- 

 ted to them ; the foliage, &c, very similar. Mature fruit not collected ; some 

 of the present collection pretty well formed has the wings abortive, while in 

 younger fruits of 1861 these are obvious and somewhat undulate. This dubi- 

 ous plant inhabits "dry hills in the middle mountains, and is a very aroma- 

 tic herb." The foliage of the dried specimens and the fruit have a pleasant 

 anisate flavor, characters unknown in the polymorphous genus Cymopterus, 

 and rendering the genus of this plant yet more doubtful. 



ARALIACE.E. 



223. Adoxa Moschatellina, L. " Subalpine ; common." 



CORNACEiE. 



Corxtjs Caxadexsis, L. In the mountains Dr. Parry gathered one or two 

 specimens of the ordinary form of this species ; and in the alpine region also 

 a depauperate form of it, some specimens of which, having a pair of leaves 

 lower down on the stem, and those from the upper axils small, niipiht readily 

 be mistaken for C. Suecica. They are distributed as No. 437 of Parry. 



CAPRIFOLIACE/E. 



224. Linn.ua borealis, Gronov. 225. Symphoricarpus montanps, HBK. 

 227. S. occidextalis, R. Br. 226. Loxicera involucrata, Banks. 228. Vi- 

 burnum pauciflorum, Pylaie. 



RUBIACEiE. 



229. Galium boreale, L. 230. G. trifidum, L., the reduced, northern form, 

 near G. palustre. 



VALERIANACEiE. 



231. Valeriana dioica, L., var. V. sylvatica, Richards. 



* Thaspium trachtpleurum (sp. nov.): glabrum: caule (pedali) striate 1-3- foliate umbellas 2-3 

 longiuscule peduii'-ulatas gerente; foliia ternatodecompositis, segmentis flliformibus mucronula- 

 tis, petiolis basi dilatatis baud scarioso-marginatis ; involucro et involucello e foliolis 1-3 subulat's 

 parvis; fioribus flavis; fructu didymo OTato lateraliter compresso. mericarpiis sectione transveisali 

 fere orbicularis, jugis alisve 5 conformibus crassis suberosis obtireissiiuis scabris cum u no commis- 

 surali a carpophore demum libero, Talleculis omnibus grosse univittatis. On the mountains, at 

 middle and lower elevations. Leaves more decompound than in the T. montanum var. tenuifolium, 

 with which I had confounded it, the segments snorter and more rigid; the fruit shorter, H to 2 

 lines long, the mericarps not at all flattened dorsally, in shape and scent like those of Thaspium, 

 and the short wings remarkably thick and corky, scabrous-roughened. A similar corky mass at 

 the commissure in the section simulates another wing or rib, except that it is partly divided by a 

 groove, which receives the carpophore.
