BOTANICAL INFOUMATION. 297 



notice till the legumes are formed. Authors have sometimes 

 described the calyx from apetalons flowers, which has caused 

 some discrepancies. Lupinus, being mainly a genus of 

 Western America, most of the species (forty-five in number) 

 have been detected by Douglas. There are fourteen species 

 of Baptisia. Virgilia hitea, here constitutes the genus 

 Cladrastus of Rafinesque. Of the genus Hoffmanseygia, 

 two species are now known to inhabit North America, II. 

 Drummondii, from Texas, and H.Jamesii, from the sources of 

 the Canadian River. CcBsalpinia pulcherrima, awd Giiilandina 

 Bonditc, are denizens of the southern extremity of Florida. 

 Algarobia too, a genus of South America (a section of 

 Prosopis in De Candolle), (and the species Proaopis glandn- 

 losa of Torrey) has been found by Dr James at the Cana- 

 dian River, and by ])rummond in Texas, The remainder 

 of the MimosecB are few in nimiber in point of species. 



The RosacedB occupy a considerable portion of the pages of 

 Part Iir. Chrysobalanus Icaco, or Cocoa Plum, (together 

 with several other tropical plants,) seems io have attained its 

 northern limits in South Florida. Spircea extends to thirteen 

 species, exclusive of Gillenia. Geum and Sieversia of Brown 

 are united, and Stylopus (Rafinesque) is also received into 

 Geum, and the number of species is fourteen. Daliharda 

 lobata, {Baldw. and Hook. Ic. pL L 76,) is united to Wald- 

 steiniay and we have the remark that Comnropsis, DC, is not 

 distinct from it. Of the curious and rare Genus Cercocarpus, 

 there are three new species of Nuttall, all of them figured in 

 Hook. Ic. plant, (tabs. 323, 324, 325.) Horkelia (of Cham, 

 et Schlecht.) has six species, Potentilla 38, (exclusive of 

 Comaruni.) The genus Rubus, (23 species,) is worked up 

 with great care. The Roses (here amounting to 13,) scarcely 

 seem to possess more tan2;ible characters than those oi 

 Europe. The North American species of Cratagus, (17,) 

 seem to us to be here for the first time clearly defined. 

 Perapkylhm is a new genus of Nuttall, allied to Amelanchier, 

 forming a low much-branching shrub in the Blue mountaiiis 

 of the- Columbia.
