valves unequal; outer one elongated, tapering and subulate, much longer 
than the inner one. Ovarium surrounded at the base by 5 glands, 2-celled: 
ovules numerous, in a double row in each cell. Fruit a drupe: nut smoothish 
or tubercled, 1-2-celled. Seeds solitary in each cell.—Trees. Leaves lan- 
ceolate or cuneate-oblong, serrated or entire.

p: 85) has referred several species, principally, at the time, undescribed. To it also 
belongs El. Varunua, Ham. ! (E. serratus, Wall. ! L. n. 2666, g, h.)

wards enlarged: æstivation imbricated. Petals hypogynous, sessile or 
scarcely unguiculate, often slightly connected at the base: sestivation 
twisted. Stamens indefinite, hypogynous : filaments dilated at the base, 
free or irregularly cohering : anthers erect, bilocular, acuminated or

pendulous; style and stigma simple. Fruit coriaceous, l-celled by
