 Vernonia erigeroides, DC, Prodr., v. p. 25; Miq., Fl. Ind. Bat., ii. p. 13. 



Arrou ; Timor Laut ; Babar ; Wetter. — Generally spread in the tropical regions of 

 the Old World. An exceedingly variable plant, and a somewhat anomalous species of the 

 genus, which comprises about 400 species spread nearly all over the tropics, though only 

 the present species has been found in Australia. The original Vernonia diffusa, Dene., is 

 a very distinct form, but we follow Bentham in reducing it to Vernonia cinerea. 



Vernonia chinensis, Less. 



Vernonia chinensis, Less. ; Miq., Fl. Ind. Bat., ii. p. 18; Hook, f., FL Brit. Ind., iii. p. 235. 

 Cyanopis pubrscens, DC, Prodr., v. p. 69. 



Timor Laut. — This species ranges from Pegu, China, and the Philippines through the 

 Malayan Archipelago. It is also recorded from the Marianne Islands.

 Hook, f., Fl. Brit. Ind., iii. p. 242; Seem, Fl. Vit, p. 140. 



Arrou ; Ki. — This annual herb is almost everywhere in warm countries, but especially 

 abundant in the Old World. It is very variable, and should, according to Bentham, 

 include all the Old World forms of the genus published as species by De Candolle. 



Ageratum conyzoides, Linn. 



Ageratum conyzoides, Linn. ; Benth., Fl. Austr, iii. p. 462; Miq, Fl. Ind. Bat, ii. p. 23; Hook, f, 

 Fl. Brit. Ind, iii. p. 243; Seem, Fl. Vit, p. 140. 



Arrou. — Also an annual, aDd common throughout the tropics, including many of the 



Polynesian Islands ; yet probably of American origin, as are all the other species of the 



genus.

 Archipelago. Blumea comprises upwards of sixty species, spread over the warmer parts 

 of Asia, Africa, and Australia.
