174 MISS L. S. GIBBS ON THE FLORA AND PLANT FORMATIONS 
Mariscus MICROCEPHALUS, Presl, Rel. Henk. i. 182; C. B. Clarke, 
in Hook. f. Fl. Brit. Ind. vi. 624. 
Spheromariscus microcephalus, Camus, 1. c. 79, 
Tenom, 700’, in ditches along the bridle-path to Melalap. Fl. Jan. 2663. 
Distrib. Borneo (B. N. B. N.E. Coast, Creagh; Melingtang on the Kapala 
river, a most elegant plant in pepper gardens, Motley, 443).  Indo-Malayan 
region and Mauritius. 
KYLLINGA BREVIFOLIA, /tottb. Deser, et Icon. 13, fig. 3. 
Tenom, 700', in ditches along the bridle-path, common. Fl. Jan. 2072. 
Distrib. Borneo (Labuan, Motley, 41, 159, 172 ; Sarawak, near Kuching, 
Haviland, 1936; Dutch S.E. Borneo, near Martapura, Motley, 89). 
SCIRPUS CLARKEL, Stapf in Trans. Linn. Soc. ser. 2. Bot. iv. (1894) 
244, 
Kinabalu, summit, 12,000-13,000’, cracks in granite. Fl. Feb. 4190, 4195. 
Distrib. Borneo (B. N. B. Kinabalu, 11,000', /Javiland—in a taller state, 
1398). 
Apart from the shorter stems—most of the flowering ones are only 15 em. 
high though those of the last season measure as much as 30-35 cm.— Miss 
Gibbs's specimens agree entirely with those collected by Haviland at a lower 
elevation, and theytconfirm me in my view that S, Clarke is distinct from 
S. subcapitatus, Thw. To the characters emphasized as distinctive in my 
original deseription I would now add the distinctly barbellate condition of 
the 6 sete.  TheyZare about twice as long as the earyopsis and barbed in 
their upper half, theipapille exceeding the diameter of the bristle. (0. 8.)
