Endemic. 
Tetracera Havilandii , n. sp. 
A climber. Leaves obovate, rounded or emarginate at 
the tip, cuneate at the base, running down to the petiole ; 
coriaceous 4 in. long, 2J- in. wide ; stiffly scabrid, hairy on 
the petiole edge, midrib sunk above, hairy with appressed 
hairs, petiole flat. Panicles small, branches covered with 
stellately arranged hairs. Sepals in fruit, subequal ovate, 
shagreened 1 cm. long, margins ciliate. Carpels 3 1*2 cm. 
long, ovate apiculate shining. 
Sarawak : Kuching, October 8, 1892 (Haviland, 1811). 
The only specimen I have seen is rather a poor one in 
fruit. The species is nearest to T. axillaris, Martelli, but

From T. radula , Martelli, it differs in its equal sepals, 
glabrous except along the edge. 
Tetracera scabricaulis , n. sp. 
Stem fairly stout, woody climbing ; at first scabrid, with 
short stiff hairs, then simply scabrid. Leaves oblong, 
obtuse base rounded, apex blunt, margins undulate be¬ 
tween the nerve-tips, stiffly coriaceous, above and beneath 
scabrid, nerves seven pairs, elevate beneath; midrib de¬ 
pressed, above hairy; young leaves hairy above, with 
scattered stiff pale hairs 10 cm. long and 4 cm. wide ; 
petiole scabrid, flattened black, 5-6 mm. long. Panicles 
10-14 cm. long, its lower half nude; branches, few, short;
