Thunbergia Vogeliana. Benth. in Hook. Fl. Nigrit. p. 470. Anders. Afr. 

 Acanth. in Journ. of Proc. of Linn. Soc. v. 7. p. 18. 



A most lovely plant, native of Fernando Po ; first detected 

 by Dr. Vogel, after whom Mr. Bentham named the species, and 

 since by our indefatigable collector Mr. Gustav Mann. In 

 many respects it has considerable affinity with the Meyenia 

 erecta, Benth., from Cape Coast, figured at our Tab. 5013 ; but 

 this is much more beautiful, with much larger and serrated leaves, 

 and larger flowers, with exceedingly large bracts, more than half 

 the length of the tube of the corolla, and very thick and fleshy. 

 The calyx, too, has much longer segments of the limb. It bears 

 copious flowers in our stove in May. 



Having adopted the genus Meyenia for the M. erecta, I have 

 thought it better to refer this to the same genus, though Dr. 

 Anderson, our best authority for Acanthaceous plants, considers 

 it in no way distinct from Thunbergia ; and, certainly, the ori- 

 ginal Indian species of Meyenia, M. Hawtayniana of Nees, has 

 july 1st, 1863.
