The generic name has been suggested by the narrowness 
of the follicle (unilaterally dehiscent seedvessel). The 
main technical difference that marks the group in its tribe, 
‘is the striking anomaly of the seed being winged at the 
base, instead of the summit. 
Both species are smooth shrubs with alternate entire 
leaves, axillary or terminal umbels borne on stalks, and 
cream-coloured or greenish white flowers. They are com- 
prised in the following general character: Corolla irre- 
gular, petals distinct, in one direction. Stamens sunk in 
the hollow of the tops of the petals. Hypogynous gland (a 
gland below the germen) solitary semicircular. Germen 
È dicled (with a stalk), many-seeded. Style deciduous. 
Stigma slanted, orbicularly dilated, flattish. Follicle linear. 
Seeds winged at the bottom. 
The species is distinguished from its congener Forsteri 
by elongately lanceolate leaves with three nerves at the 
base. 
We should observe that the flowers are exceedingly fra- 
grant; with the flavour of those of OLEA odoratissima.
