Distrib. East tropical Africa (Mozambique). 



This species, to which we consider our Socotran plant may be referred, has 

 been hitherto recognised as an east tropical African plant only. It is nearly allied 

 to a west tropical African form, Ad. Honghel, DC, but has villous lines inside the 

 base of the corolla tube. Probably it will be eventually found over a consider- 

 able district in east tropical Africa. 



On Socotra the plant varies much in size of leaf and of flower. The African 

 plant is small-flowered, resembling those found on the south side of the hills of 

 Socotra. Some of our plants have flowers twice as large as those figured by 

 Klotzsch. Klotzsch mentions glands on the leaves of his plants, but questions 

 their normality. There are no such glands on our specimens. 



This Socotran plant is, I believe, the one referred to by Wellsted (in Journ. 

 Eoy. Geogr. Soc. v. (1835), 198), as the Assett tree. (See page 101 of this 

 volume. ) It is abundant, and forms in many places most fantastic plants. 

 Some of them have a broad basal trunk as much as six or eight feet in diameter,
