The rhachilla disarticulates above the two lowest empty glumes of the spikelet, 
falling off in one piece on which the nut-bearing glumes persist—Kyllinga 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, 4 in. 
broad. Head of 1 globose dense spike, } in. in diam., straw-coloured ; 
bracts 3, lowest 24 in. long, similar to the leaves. Spikelets 5 in. 
long, each perfecting 3-2 nuts. Nut-bearing glumes elliptic-lanceolate.

The main difference ‘between this and K. macrocephala is that the stems in 
i, leucocephala arise from a dense bed of the fibres of the torn leaf-sheaths. 
K. leucocephala, K. Schum. in Engl. Pfl. Ost-Afr, C. 123 (i.e., Holst, 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
