1. Lendneria humilis (Soland.) Minod. 



Capraria humilis [Soland. in] Ait., Hort. Kew. 2: 354. 1789. "Nat. of 

 the East Indies. John Gerard Koenig, M.D. Introd. 1781, by Sir 

 Joseph Banks, Bart." Identified by Bentham in DC. Prod. 10: 383. 

 1846, as species here considered, his determination with an "!" Our 

 plant has been occasionally reported as an introduction into the Old 

 World Tropics. 



Stemodia parviflora Ait., Hort. Kew., ed. II. 4: 52. 1812. "Nat. of South 

 America. Cult. 1759 by Mr. Ph. Miller." Miller's plant was derived 

 from Houston who collected at Cartagena in Colombia as well as in 

 Mexico and the West Indies. The original introduction of Houston, 

 published as Erinus penicillatus Mill., Gard. Diet. n. 5. 1768, differs 

 so essentially from the account of Aiton's plant, especially in denoting 

 a plant with glabrous stems and leaves, as to lead to the supposition that 

 the latter was described from specimens of a different origin. 



Stemodia arenaria H. B. K., Nov. Gen. et Sp. 2 : 357. pi. 175. 1818. " Cres- 

 cit in ripa inundata fluminis Magdalenae prope Banco et El Pefion inter
