124 LAURACFAE SMITHSONIAN CONTRIBUTIONS TO BOTANY
1. Buds large, many-scaled, outer scales smaller than inner;
petioles long (-% the leaf blade length); midrib giving rise
to several major lateral veins above the middle; plants
smelling of camphor ............ C. camphora
1. Buds small, few-scaled, outer scales about as large as bud;
petioles short (-l/6 the leaf blade length): midrib not giving
rise to major veins above the middle; plant smelling of
cinnamon.
2. Leaves narrowly lanceolate, long-tapered at apex; basal
veins arising well above leaf base, attenuating well
before apex ................ C. burmnni
2. Leaves broadly ovate, blunt or round at apex; basal veins
arising at leaf base, continuing almost to apex .....
......................... C. verum
Adjanohoun et al. (1985: 127, pl. 94) reported medicinal use
of Cinnamomum verum (as C. zeylunicum) on Dominica.
Excluded Lauraceae
The genus Phoebe (united with Cinnamomum by Kostermans,
1961) is similar to Persea in that it also has an inner
(fourth series) group of 3 sagittate staminodia and a persistent
perianth in h it However, it has triplinerved leaves, a character
also exhibited by Cinnamomum. Grisebach (1864:711) reported
identifications of Imray collections from Dominica
under the names Phoebe membranacea and Persea nutans.
Both binomials were cited by Mez (1889:202) in synonmy of
Phoebe cubensis, although Mez didn't cite the Imray collections.
The Imray collections were cited by Mez (Imruy 149,
335) under Ocotea imrayana Mez (1889:274). Thus, the
attribution of Phoebe cubensis to Dominica by Mez (in Urban,
1905,4245) is apparently an error. No material attributable to
Phoebe has been seen from Dominica, although it can be
expected. Howard (1981:45; 1988, 4:254) followed Kostermans
in treating Phoebe in Cinnamomum.
Cassytha filiformis Linnaeus was reported for Dominica by
Velez (1957:79). This is a parasitic, aphyllous vine, like
Dodder (Cuscuta) but has the typical Lauraceous androecium
with 9 bilocular stamens and 3 staminodes. Although this
species is widely scattered and expected, no collections from
Dominica have been seen.
