258 UMBELLIFER.E. [Sanicuia. 



correctly united the S. Canadensis of Linnaeus, with ♦S'. Marylandica. I do not see the necessity even of 

 making a variety of it; and the Lirinaean character is equally applicable to the one as to the other plant.

Hab. North -West coast of America. A. Menzies, Esq. On the banks of the Columbia, in dry sandy 

 soils. Dr. Scouler^ Douglas. — This is a very distinct species from the S. Marylandica, but very nearly 

 allied to the S. Liberia of Charaisso in Linnaea, v. 1. p. 253, a native of Chili. If it should prove to be the 

 same, it has then a very extensive geographical range; for that author states it to be the " S. Mary- 

 landica, of Willdenow's Herbarium, an Humboldtian plant, foxmd. at Caripe." The Naturalists of Captain 

 Beechey's Voyage, gathered our plant in California.

Har. North -West coast of America. A. Menzies, Esq, — This plant has very much the appearance of 

 the genus Arctopus, the leaves and segments of the leaves being curiously pinnatxfid at the margin, with 

 crowded, acuminated, unequal teeth. The umbel is nearly simple, and scarcely rises above the foliage. 

 The root is fusiform.

4. S. hipinnaiifida ; caulescens, foliis bipinnatifidis inferioribus longe petlolatis segmentis 

 remotis obovatis seu obovato-lanceolatis acutis inciso-serratis serraturis acutissimis, racbide 

 acutissime dentata, pedunculis elongatis, umbellis compositis subproliferis, umbellulis 

 globosis. (Tab. XCll.)— Douglas, MSS. 



Radix fusiformis. Caulis erectus, graciHs, ramosus, glaber, ut et tota planta, subpedalis. Folia bipin- 

 natifida, inferiora et radicalia longe petiolata, petiolo basi dilatato vaginato ; segmentis (primariis prsecipue) 

 remotis, obovatis, obovato-lanceolatisve, varie lobatis inciso-serratisque, serraturis acutissimis. Rachis 

 linearis, profunde dentata, dentibus horizontalibus acutissimis. Folia superiora sessilia, segmentis omnibus 

 angustis, acuminatis. Pedunculi elongati. Umbell<B subcompositffi, involucre laciniato, laciniis inaequalibus 

 acuminatis; radiis gracilibus non raro proliferis. Umhellulm ^\oho^, densiflorse. Flores fceminei nt videtur, 

 sessiles.
