THE BINDWEED TRIBE. 



Herbs or shrubs, usually twining, rarely creeping, or erect, by Lindl. re- 

 ferred to 28 genera. Of these, though much underrating, Spreng. syst. 

 enumerates about 150 for S. America, Mexico and the W. Indies; 18 for 

 Europe ; 16 for N. America ; 8 for N. Africa ; 6 for Guinea ; 7 for the Cana- 

 ries ; 5 for Siberia ; 4 for E. Africa ; 4 for the Mascarenhas Islands ; 2 

 for Madagascar ; 4 for Arabia ; 4 for China ; 3 for Japan ; 3 for Tauria ; 

 2 for the Orient; 1 for Dahuria ; 1 for Persia; and 1 for the Azores. 

 Many are common to several parts of the world. In S. Africa, excluding 

 Falkia, Retzia, Lonchostoma and Cuscuta, have been found 23 species, 

 {Harvey) ; in N. Holland and the South Sea Islands more than 50 ; (R. Br.) 

 and in the E. Indies, according to Choisy, 130; viz. 5 of Rivea ; 31 of 

 Argyreia, (including A. floribunda. Wall.) ; 1 of Bl'mkworthia ; 2 of Moor- 

 croftia; 2 of Qiuamoclit ; 3 of Batatas ; 3 of Pharbitis ; 3-4 of Colony ction ; 

 2 of Lepistemon ; 53 oilpomoea; 6 of Convolvulus; 4 of Aniseia ; 1 of 

 Calystegia ; 1 of Hewittia ; 1 of Skinnera ; 4 of Parana ; 2 of Neuropeltis ; 

 4 of Breweria ; 1 of Cressa ; and 2 of Evolvulus. They are to be found 

 everywhere both in the mountains and plains, but most abundantly on 

 the latter. 



" Their roots abound in an acrid milky juice, which is strongly purga- 

 tive ; this quality depends upon a peculiar resin, which is the activa prin- 

 ciple of the Jalap, the Scammony, and the others whose roots possess 

 similar qualities." (Lindl.)
