А tree 30—40 feet high, with a straight trunk and a fine head of spreading branches, 
called by the natives kyai-gyce; it is also found at Moulmcin. It forms a species quite 
distinet from most of the preceding, differing in its much broader leaves, on short petioles, 
and in its flowers arranged in pairs, and its fruit with winged margins. Its leaves, very 
crowded at the extremity of the branches, are 16 in. long, 6 in. broad, on a petiole 6 lines 
long, 4$ lines broad, with about 13 pairs of very spreading nerves; raceme upwards of 
3 feet long, rachis 6 lines thick below; pedicels 1 line long; calyx 4 lines long; petals 
10 lines long, 6 lines broad; stamens above an inch long; fruit (perhaps immature) 11 
lines long, 8 lines broad, quadrate, with winged margins, its single seed is suspended, 
5 lines long. 
8. PETERSIA. 
This is a singular genus, proposed by Dr. Welwitsch for a plant discovered by him in 
Angola, a tree of large size, with an expanded сотозе head: it has terminal pendent 
racemes, оп a rather thin rachis, bearing many small flowers, each upon a long slender 
pedicel, which is bibracteolated in the middle; the calycine limb consists of 4 small 
rounded erect sepals, distinct in the bud; 4 obtuse petals, fixed by their claws to the 
staminiferous tube; an inferior turbinate 4-winged ovary, which is 4-locular, with several 
ovules suspended in the summit of each cell; the fruit is of a narrow linear cylindrical 
shape, coarsely hispid, with 4 very large extremely broad membranaceous wings. By 
abortion it is unilocular, with few linear compressed suspended seeds.
