21. P. sp. nov., Hiern, MSS. 
Amongst palms Golungo Alto. Cuango River, Welwitsch, 
5304! 
22. P. mussmnvorvEs, Baker, in Journ. Linn. Soc. (Bot.), vol.

EXcLUDED SPECIES. 
P. invotucrata, Baker, in Kew Bulletin (1895), p. 66. 
This is Spermacoce dibrachiata, Oliver—Fuambo, Carson, 40! 
which is common in the Shiré Highlands (Buchanan, 204, 1094, 
3951). 
P. speciosa, Baker. 
This isa new species of Otomeria closely allied to O. dilatata ; 
this latter genus should, I think, be included in Pentas, but it is 
distinctly not advisable to make alterations in the genera unless 
the entire order is monographed. 
The original Otomeria dilatata, Hiern, contains the following 
plants : Barter, 1237! Congo, Hens, 34! Blantyre, Last ! Milanje 
Whyte ! Buchanan, 310! 1493! 
Otomeria speciosa, S. Elliot, contains Welwitsch, 5316! 5317! 
and Scott Elliot, 5239 and 5392! 203 miles south of Niamkolia 
Tanganyika, Carson!
