Botanical Name
| Hopea sulcata Symington |
| Genus | Hopea |
| Family | Dipterocarpaceae |
| Distribution | This species is endemic to the Malay Peninsula. It occurs in Kedah, Perak, Pahang, and Johor. It appears to be of scattered, rare occurence, and to live at low elevations or on hills up to 500 m. Many of its former localities no longer exist and if not already extinct, it must now be regarded critically endangered. |
| Bole Characteristics | Tree of the smooth-barked Hopea group, up to 2 m girth; buttresses short, tending to develop a stilted habit; bole grey-brown with lighter colored patches, becoming irregularly and rather closely fissured; vertical rows of white corky lenticels common; occasionally small exudations of clear dammar may be seen.
|
| Herbarium Characteristics | Elliptical, shortly acuminate, about 10 x 5 cm but rather variable, drying silvery grey above and sparsely silvery beneath; midrib slightly raised on both surfaces; venation sub-dryobalanoid, main nerves about 15 pairs with short intermediate nerves and almost invisible scalariform reticulations. |
