Hillebrand notes this species from "along cultivated fields in 

 Pauoa, Oahu. A native of China and India; a recent arrival." 

 It does not seem to have spread outside of Pauoa, where it is 

 now rather common.

HELI0TR0PIU3I L. Sp. PI. 130. 1753. 

 Heliotropium curassayicum L. Sp. PI. 130. 1753. 



This widely diffused species is common in low places along 

 the beach, presumably on all of the islands of the group. It is 

 found on Oahu and Kauai, at least. 



May (2383); original locality, "in Americae calidioris mar- 

 itimis."

LANTANA L. Sp. PI. 626. 1753. 

 Lantana camara L. Sp. PI. 627. 1753. 



This species has become the most noxious plant in the Is- 

 lands. Introduced in 1858, it is now abundant, and has ruined 

 hundreds of acres of valuable pasture land. It forms impene- 

 trable thickets on the slopes and in gulches of the lowlands, 

 and has even invaded the lower forests. Here it grows in 

 thick clumps, the stems often becoming weak and vine-like, 

 and intertwining in a very intricate manner. The flowers 

 vary in color, some being almost white, others purplish, and 

 some are orange.
