 Spikelets i in. long, each perfecting 8-5 nuts. Nut-bearing glume

The rhachilla disarticulates above the two lowest empty glumes of tlie spikelet, 

 falling off in one piece on which the nut-bearing glumes persist — Kyllinrja and 

 Pycreus are two closely allied genera ; they cannot be distinguished by the number 

 of flowers (or nuts) to the spikelet. According to the character relied on here 

 to separate them, K. macrocephala is an unmistakable Kyllinga. 



37. K. leucocephala, Boeck. in Flora, 1875, 257. Stems 1 ft. 

 high, densely tufted, thickly surrounded at the base by the torn 

 lacerate dark-brown tough leaf-sheaths. Leaves 4-5 in. long, 1 in. 

 broad. Head of 1 globose dense spike, J in. in diam., straw-coloured ; 

 bracts 3, lowest 2J in. long, similar to the leaves. Spikelets \ in. 

 long, each perfecting 3-2 nuts. Nut-bearing glumes elliptic-lanceolate.

The main difference between tliis and K. macrocephala is that the stems in 

 K. leucocephala arise from a dense bed of the fibres of the torn leaf-slieatlis. 

 K. leucocephala, K. Schum. in Engl. Pfl. Ost-Afr. C. 123 (i.e., Hoist, 2018, collected 

 at Tanga), has a single row of stems having their bulbous bases contiguous on a hori- 

 zontal rhizome. It is very young (possibly = K. crassipes ?) but I believe cannot be 

 K. leucocephala, Boeck. 



38. K. eximia, C. B. Clarke in Durand d- Schinz, Conspect. Fl. 

 Afr. V. 529. Stem 1 ft. long, at the base somewhat thickened by sheaths 

 hardly torn. Leaves as long as the stem, ^-J in. broad. Head of 

 1 globose spike exceeding J in. in diam., dense, pale cinnamon-coloured ; 

 bracts 3, lowest 4 in. long, similar to the leaves. Spikelets J-^ in. 

 long, each perfecting 3-5 nuts, much compressed. Nut-bearing glume 

 ovate, acuminate, acute, 3-4-ribbed on each side ; keel wingless, some- 

 what scabrid. Young nut very large.
