Observations
. – The
type
(the only collection known when the species was described) is sterile. Four recent collections have broadened our knowledge of this species.
Dumetz 696
(st.) is also from Mandena, at an altitude of
10 m
.
Rajoharison & al. 222
is from Antsotso, and occurs in “forêt sur sable”. Its fruits are round, smooth, ca 1.3 ×
1.3 cm
, with the tepals persisting on top of the fruits, and its infructescences are short, up to
3 cm
long.
Ramison & Rabehevitra 557
is from Sainte Luce in “forêt littorale”. The inflorescences are short, ca
2 cm
long, clustered distally on the twigs and resemble a terminal inflorescence. The young growth is densely ferruginous pubescent although the indument wears off quickly. Leaves of this species are to
10 cm
long, with an obtuse to rounded base and a rounded or emarginated apex. Lateral veins are immersed on the upper leaf surface and immersed or weakly raised on the lower surface. The fruits are ruminate.
Cryptocarya oblonga
, a small tree to
10 m
tall, is restricted to asmall area of coastal forest on sand Nof Tolagnaro (Fort Dauphin).
