 above connnon t^-enera there occur othei's in those ])ai'ts which in their 

 essential characters differ but slightly from the nearest allies found in 

 Alabama, forming with them such pairs as Glaueidium and Hydrastis, 

 Sphaerostemon and Schizandra. Ste})haiiandra and Neviusia. Corv- 

 lopsis and Fothergilla, Paris and ^Nlodiola, Scilla and Quaniasia, liox- 

 biirghia and Croomia, and some others. 



The iuunl)er of types indigenous to Alabama w'hich are identical 

 with species found in eastern Asia is small, amounting scarcely to 

 forty. Though this number by itself considered is insigniticant, it 

 must be viewed together Avith the fact that every one of the genera 

 common to Alabama and eastern Asia is represented in the latter 

 region by one or several species closeh'^ allied to the forms found in 

 Alabama, so closely in not a few cases as to be dilHcult to sepai'ate.
