aes: 
OF CEYLON PANGIACES. 197 
A very large forest-tree, not uncommon in the Central Province, at an 
elevation of about 3000 feet. The young branches are tomentose, and 
the growing apices are covered by the imbricated, rather large, concave 
stipules. The leaves are from 5 to 12 inches long, and from 2 to 4 
inches wide, rounded at the base, coarsely dentate or sinuate upwards, 
and terminating in a narrow acumen; veins underneath tomentose, as 
are the cylindrical petioles, which are 2-3 inches long. Flowers 6 lin. 
wide, pale green. Fruit spherical, containing from 1 to 3 roundish or 
oblong seeds 9—11 lin. in diameter. 
Closely allied to Hydnocarpus, from which genus however it differs 
in many important particulars, as a comparison of the generic characters 
will show. The Cinghalese call the tree Teitigaha or Tettigass, and 
extract an oil, which they use for burning, from the ripe seeds. The 
wood is of little or no value.
