The tropical Ochna Schweinfurthii and Hexalobus senegalensis 
increase their southern limit. 
Intermediate distribution is shown for Polygala abyssinica and 
Odina Schimperi, known only from East Tropical Africa, Trans- 
vaal and Natal, and Pepalanthus Wahlbergii, known from South- 
east Afriea, Angola, and Transvaal. 
Potamogeton natans, occurring in the Matopos aud on the 
Zambesi, is quite new for Tropical Africa ; and the Matopos is 
a new locality for the cosmopolitan, but rarely found, Nitella 
hyalina. 
An interesting record is the genus Pseudolachnostylis, previously 
known only from Angola and German East Africa, and Euphorbia 
matabelensis, collected by Penther, is one of Pax's new types. 
Twenty-three new species are described. The most interesting 
is perhaps the handsome grass aptly named Erianthus terctifolius 
by Dr. Stapf, which is so conspicuous ou the banks and islands 
of the Zambesi above the Falls; and a very characteristic 
Hlephantorrhiza trom the Matopo Hills makes a new species in 
this limited genus. 
List or Puanrs collected in August, September, and October 
1905, in the Matopo Hills and at the Victoria Falls, 
Zambesi, Southern Rhodesia.
