BOTANICAL DESCRIPTION OF SPECIES. 



RENANTHERE/E. 



1. E. coriaceaA. Cunn. Leaves elongated, thick, shining, equally green above 

 and below, veined longitudinally; umbels solitary, lid hemispheric; fruits truncate- 

 ovate, border of orifice depressed, valves inclosed. 



2. E. amygdalina Lab. Leaves thin, equally green above and below; veins not 

 much spreading, oil-dots copious, transparent; umbels solitary, flowers small, lid 

 almost hemispheric; fruits truncate-ovate, border depressed, valves inclosed. 



3. E. risdoni Hook. Leaves, sometimes all, even on the flowering branches, 

 opposite, ovate-cordate and more or less connate, or sometimes those of the flower- 

 ing branches alternate, broadly lanceolate and falcate, rather thick, with oblique 

 veins scarcely conspicuous, the intramarginal one at a distance from the edge. 

 Peduncles axillary or lateral, terete or angular, bearing each an umbel of 4 to 8 

 flowers. Fruit subglobose-truncate, the rim rather broad, flat; valves inclosed. 

 Bark smooth, coming off in regular patches, varying from whitish to dark brown. 



Adapted to cool, moist regions. 



4. E. stellulata Sieb. Leaves small, thick, equally green above and below, veined 

 longitudinally; umbels solitary, flowers very small, numerous, lid semiovate-conical; 

 fruits truncate-globular, border depressed, valves inclosed. Bark rough, scaly and 

 fibrous. 



Adapted to cool, moist regions. 



5. E. eugenioides Sieb. Leaves equally dark green above and below, shining, 

 very inequilateral at the base, much transparently dotted; umbels mostly solitary, lid 

 semiovate; fruits truncate-globular, border depressed, valves barely inclosed. 



6. E. piperita Sm. Leaves less shining beneath, with many transparent dots; 

 umbels solitary, lid semiovate-conical; fruits truncate-ovate, border compressed, 

 valves inclosed. 



7. E. pilularis DC. Leaves rather less shining beneath; umbels mostly axillary, 

 their stalks compressed, lid semiovate-conical; fruits truncate-ovate, border depressed, 

 valves inclosed.

 stalks slender, lid hemispheric, pointed; fruits truncate-ovate, border compressed, 

 valves barely inclosed. Bark rough, persistent, and fibrous.

 inequilateral at the base; umbels solitary, calyces granular-rough, lid hemispheric; 

 fruits truncate-ovate, border compressed, valves inclosed. 



10. E. capitellata Sm. Leaves thick, elongated, rather less shining beneath, 

 very inequilateral at the base; umbels axillary, stalklets none, lid hemispheric; 

 fruits semiovate below, border broad, convex, emersed, valves much exserted.
