Ocotea eggersiana
Ocotea eggersiana Mez, 1889:363.-Howard, 1981 :2W, 1988,4:264.
Laurier caca, laurier fetide.
Tree or shrub; leaves small, to 7.5 cm x 4 cm, with domatia;
flowers unisexual.
Lesser Antilles; not recently collected in Dominica but
reported from La Plaine (Ramage s.n. at K), Rosehill [near
Lisdara Estate] (Eggers 657 at GOET), sine loc. (Eggers 988,
Imray 127,147 at K, Eggers 327 at GOET).
The Dominican materials cited by Grisebach (1860:281) as
Nectandra exaltata belong here, according to Mez (1889:364).
This species is part of a complex apparently involving the
larger-leaved 0. floribunda and other “species” with small
(40 cm long) leaves: 0. dussii (flowers bisexual; domatia
present); 0. I’herminieri (flowers bisexual; domatia absent);
this species .(flowers unisexual; domatia present), and even
material called 0. eggersiana (flowers unisexual, domatia
absent). Only 0. eggersiana is reported from Dominica,
although the others are reported from the French islands
(Fournet, 1978).
Much of the material (US) from the French islands that was
distributed as 0. eggersii (sic) appears to be 0. dussii, some
(Duss 3829) being syntypes of 0. dussii.
Ocotea imrayana
Ocotea hapnu Mez, 1889:274.-Howard, 198155; 1988,4:265.
Small tree; leaf blades glabrous, obtuse to short-acuminate;
flowers bisexual.
Guadeloupe to Martinique; in Dominica without locality:
Imray 335 at K, GOET. This material was identified by
Grisebach as 0. cernua.
A collection (US) from Martinique (Duss 4562) appears to
be this species. A specimen (W) from 100 m at La Chaudibe
(Hodge 3507) is doubtfully referred here. The flowers seem
quite glabrous but, unlike what I assume to be the case in true
0. imrayana, a young leaf bud is remarkably fermginoustomentose
and the pistil appears to be aborted (flowers
unisexual). The stamens are 4-locular but the lower two locules
appear to be latrorse (opening to the side) rather than introrse
(on the outer six stamens) and extrorse (on the inner three
stamens). I am unable to identify it with any certainty.
A duplicate (GH) was identified by Barneby and Allen as
Nectandra dominicana, but I do not find that the flowers have
the distinctive densely glandular-punctate tepals of that species.
