Mountains. The particular field of Mr. Geyer's operations, 

 and the extent of his journey, were undecided at the time 

 of his departure from St. Louis. Mr. Luders expects to 

 spend the next winter, and perhaps the ensuing summer, 

 at a station of some Roman Catholic missionaries, on the 

 upper waters of Lewis and Clarke's or Great Snake river. 

 These botanists being well acquainted with the vegetation 

 of the general valley of the Mississippi and of Lower Mis- 

 souri, will doubtless avoid the common and better known 

 plants of this region, and thus their collections may be ex- 

 pected to prove unusually choice and valuable. The third 

 collector. Dr. Lindheimer, a very assiduous botanist, intends 

 to devote a i^w years to the exploration of Texas, and he 

 pledges himself to exclude from his sets all the common 

 plants of the South Western United States. The collec- 

 tions will be assorted, distributed, and for the most part 

 ticketed by Dr. Englemann, of St. Louis ; he will also be 

 assisted by Drs. Torrey and Gray. 'J'he three explorers 

 are entirely independent of each other, and their collections 

 are to be separately subscribed for. 



The price of the Rocky Mountain collections of Geyer 

 or of Luders is fixed at ten dollars (or two guineas) per 

 hundred ; that of Dr. Lindheimer's Texan collections at 

 eight dollars (or £\. 13s. 6d. sterling) per hundred, payable 

 on delivery of the sets, at St. Louis by Dr. Englemann, at 

 New York by Wiley and Putnam, and Prof. Gray, at Cam- 

 bridge, Mass., to Avhom subscribers may address them- 

 selves; {postpaid) by mail. — (Silliman's Journal iox July.)

iiWy'iAam Paxt. Whitish flowered currant. A hnrdy shrub ; growing four feet high ; with 

 uhili^!h flowers; a eeedlins production; increased by cuttings and layers; grown in any 

 good soil. Pax. Mag. Bot. Vol. X. p. 55. 



The red flowering currant {Rlbes sanguineum) is well 

 known as one of the most ornamental shrubs, though yet 

 but little cultivated in the vicinity of Boston. The present 

 subject is said to be a seedling production of that species, 

 and is like it in most respects. " The flowers are of a very 

 delicate French white, with a pink eye," and the racemes 

 are more profuse than in the former. It forms a beautiful 

 contrast with the sanguineum, and, being easily grown, is 

 a very desirable acquisition. It will thrive in almost any 

 soil. (Pax. Mag. Bot. April.)
