A new genus in the Compositse has been dedicated to the 

 memory of I. N. Nicollet, Esq., "who spent several years 

 exploring the country watered by the Mississippi and Mis- 

 souri Rivers, and who was employed by the United States 

 government in a survey of the region lying between the 

 sources of those rivers," — is to be found among these descrip- 

 tions made out by Dr. Gray, under the name of Nicollet/a 

 occidentalis. It belongs to the tribe SenecionidejE, and the 

 sub tribe Tagetine^. The plant is agreeable on account of 

 its odor, and grows in naked sands, on the banks of the Mo- 

 hatve River, flowering in April. 



A notice of the Fremontia. already spoken of, gives some 

 further details concerning this curious and interesting plant, 

 and is accompanied with a plate of several figures of its 

 flowers, seed, «fcc. 



In the collection, were numerous specimens of the Conifera, 

 which suff'ered less than those of other plants, and most of

 from longitude 111° to 128°, and through a considerable 

 range of latitude, was, however, a new and singular species 

 of pine, which from its general use among the Indians of that 

 region, as an article of food, and, from its flavor, w^as called 

 the nut pine (Pinus monophyllus Tojt. 4* Frem.) It is 

 chiefly remarkable among the true pines for its soUfanj 

 leaves, which are from an inch to two and a half inches long: 

 often more or less curved, scattered, very stout. The seeds 

 are oblong, about half an inch long, without a wing : the 

 kernel of a pleasant flavor, resembling that of Pinus Cembra.

In perusing the pleasant pages of this portion of the Re- 

 port, we frequently meet with names of plants familiar to us, 

 from their agreeable associations, as connected with our 

 flower-gardens, or with the weeds which grow around our 

 houses. Along the banks of the Roseaux, or Red River, in 

 latitude 41° 59' 31'', and on an elevation of 4670 feet above 

 the sea, were "fields of Malva rotundifolia." On the 6th of 

 March, 1844, in the vicinity of the Sacramento River, they 

 came to a valley " gay with flowers — some of the banks be- 

 ing absolutely golden with the Californian poppy, (Esch-
