Although this investigation has added nothing new to 

 botanical science, vci ii is necessary that the existing 

 - and plants should be described so as to be identified, 

 and their importance properly estimated. A familiar de- 

 scription has been prcfern d to strictly botanical language, 

 to convey all that is necessary with regard to the present 

 tati n. The catalogue will be added to during the 

 ensuiug season. 



For present purposes, the plants arc arranged simply 

 in alphabetical order, without reference to any particular 

 Scation.
