Chilense to G. Piravira, Mol., which is the same as our G. citrinum, a name that of course must yield to 

 that of Molina's, although we are yet ignorant where it is published. When Lessing referred hither the G. 

 Chilense, he must have trusted a little to Sprengel's character, as we did, for no other plant of Chamisso, 

 from whom Sprengel had it, approached more closely. At p. 260, Lessing informs us that he had overlooked 

 a packet, the description of which would form a supplement. Among these he adopts the G. Chilense, Spr., 

 from California, and although, perhaps inadvertently, he refers to the former part, where he united it to G. 

 Piravira, yet he now adopts the name from Sprengel; contrasting which with the character given by that 

 author, we have now no doubt of the present being what he intended ; and as it is not a Chilian, but a 

 Californian plant, we have considered it necessary to change the specific name. To G. lanuginosum, Kunth, 

 it is very closely allied ; but although Sprengel unites them, we consider the leaflets of the involucre " argute 

 acuta fuscescenti-virescentia" of the bitter, may keep it distinct. Sprengel places this plant erroneously 

 among the " Filagines," but it is much more nearly allied to G. polycephalum, and particularly to G. 

 decurrens. We may here remark, in addition to the two Chilian species already noticed, and described at p. 31, 

 that our G. ulophyllum coincides with Lessing's G. Indicum, and G. coarctatum with his G. stachydifoliwn. 



2. Gnaphalium decurrens; caule herbaceo lanato, foliis lineari-lanceolatis acuminatis 

 decurrentibus supra scabriusculo-puberulis subtus albo-lanatis, corymbis paniculatis glomer- 

 atis paucifloris, involucri foliolis oblongis acutis argenteis nitidis. — Ives, in Sillim. Amer. 

 Journ. — Spreng. Syst v. 3. p. 478. Lessing in Linncea, v. 6. p. 525. 



In the specimens before us, the leaves are narrower than in those we possess from the United States, 

 and the panicle more destitute of foliage, but we can see scarcely any other difference. The woolly coat on 

 the underside of the leaves is subject to be rubbed off. The Californian state approaches very nearly to G. 

 Sprengelii, above described, from which it principally differs by the leaves not being cottony on both sides. 



3. Gnaphalium luteo-album. Linn. 



This was also found at California by Mr. Menzies, and it extends as far north as Nootka Sound.

1. Ipomaea sagittifolia ; glaberrima, caule volubili, foliis sagittato-hastatis sinu profundo 

 auriculis acutis, pedunculis sub flore incrassatis supra medium bracteolas duas lineares ger- 

 entibus, calycibus obtusis, limbo corolke integerrimo. — Pursh, Fl. Am. v. 1. p. 144. — Con- 

 volvulus sagittifolius. Mich. Am. v. 1. p. 138. — C. speciosus. Walt. 



The style is bifid; stigmas two, globose and white; so that this is not a Convolvulus, as defined by Brown, 

 but an Ipomma.

 1. Gilia squarrosa; pubescenti-glandulosa, foliis bracteisque pinnatifidis laciniis incisis 

 subulatis pungentibus, floribus glomeratis. Hook. — G. pungens. Douglas, MSS. in Bot. 

 Mag. t. 2977, (anno 1830.) — Hoitzia squarrosa. Eschcholtz, in Mem. Acad. Imp. St.

At the time Dr. Hooker published this species in the Botanical Magazine, he was not aware of a specific 

 name being already given to it by Eschcholtz, which, however, has the claim of priority. Messrs. Lay and 

 Collie appear to have found it about Monterey, Mr. Douglas near the source of the Multnomack River, one
