In his brilliant exposition of the Vernonias known at that 

 time Lessing describes a V. arbuscula from Mauritius. My 

 attention was called to his plant by a statement of Lessing 

 that it recalled V. arborescens (L.) Sw. On a visit to Berlin 

 I examined the type of the species, and was greatly astonished 

 to recognize in it a throughout typical V. arctata Gleason. 

 The specimen is labelled: Ex herb. Kunth. Vernonia arbus- 

 cula n. sp. Isle de Bourbon. Salisbury ded. 1816 . It is 

 a puzzle how Mauritius (= Isle de Bourbon) came to be 

 designed as the habitat of the plant; quite certainly it is a 

 typical V. arctata Gleason. 



Though strongly resembling V. bahamensis Griseb., 

 V. arbuscula is a good species, differing from V. bahamensis 

 in the shape and colour of its leaves, as well as in their nerva- 

 ture. In V. bahamensis the lateral veins are 4 6, ascending 

 at oblique angles, in V. arbuscula they are only 2 3, issuing 

 at nearly right angles. 



Vernonia complicata Griseb.

Pappi seta? interiores persistentes, numero 45, tenues,

 papillosis, pilis apicalibus brevissimis aut nullis. Antherse

Hab. in Cuba: Wright n. 2790 (Bss, DC, G, orig. spec, 

 KU, P, S); in rupibus litoralibus prope Leeward Point ad 

 sinum Guantanamo, Mart. 1909. Britton n. 2225 (KU). 



A species of very peculiar habit due to its small, broad, 

 curled, densely tomentose leaves and few, solitary heads.
