place and season : smaller, but flowers larger. 

 Autumnal, annual, 6 to 10 inches high, hardly

 of Bartram's garden cannot account for the 

 spontaneous production of these plants and sev- 

 eral others in their garden.

I must conclude here this beginning and mo- 

 del of a proper Lexicon of our N. American 

 Flora. To continue the whole Flora even in 

 this concise form, would fill several large vol-

 Palms, Grasses and Ferns, Shrubs and Vines . . 

 Our Botanists know or admit of hardly more 

 than one half Botanical Works are filled with 

 plants neglected by them, because rare and lit- 

 tle known. Our Herbals or Botanical Collec- 

 tions contain a crowd of plants as yet unnoticed 

 and undescribed. Baldwin's Herbarium has 

 been a Botanical mine for 20 years past, for Elli- 

 ot, Nuttal, Torrey, &.c. and will continue so a 

 long while. Nuttal will soon increase the Ore- 

 gon Western Botany by perhaps 1000 N. Sp. — 

 Whoever applies to the proper study of a single 

 Genus or family increases or doubles our know- 

 ledge of it. Torrey has lately increased our 

 Cyperacea alone to 25 genera and 326 species 

 and he has not exhausted this tribe ; but omit-
