The present group of Cypertis is, in Tropical Africa, very difficult to divide into 

 species. The above description is drawn from Mann, 1358, as a typical form ; in 

 this the stem is more than 3 feet high, and there are in the umbel more than 150 

 spikes containing moi-e than 600 spikelets, Mann, 2107, is a foot high, slender,, 

 ono stem ciirr^ing only 6 spikes and 35 spikelets, and is referred by Boeckeler to 

 C. leptocladus, Kunth ; but was marked by Hooker, f. as " = Mann, 1358," with 

 which determination I agree,

The type form of this species has the umbel rather loose, the spikelets longer and 

 darker-coloured than those of C Mannii. As to the synonymy, the plant of 

 Kersten marked Deckenii by Boeckeler, that of Volkens marked clarkeamis by 

 Schumann, and that of Johnston marked leptocladus by Oliver (all tliree from 

 the same level on Kilimanjaro) have been placed side by side and admitted to be 

 identical. Some of the Nyasaland material also appears identical ; but other Nyasa- 

 land material, at present arranged as Deckenii, Las very dense umbels, or paler 

 or shorter spikelets, and may hereafter be separable. This plant in no wise approxi- 

 mates to the genus Mariscus ; and it must have been by some error in ticketing that 

 K. Schumann could have imagined that it was a Mariscus of mine.
