Acomat St. Christophe, aukuma (Carib).
Tree to 20 m with scaly bark leaf-blades ovate-elliptic,
cuneate-rounded at the slightly emarginate base, apex roundedacuminate,
5-15 cm long; pedicels to 1 cm long; fruit ovoid,
yellow, to 2.5 cm long.
West Indies; in Dominica as a timber tree at lower elevations
(Hodge and Taylor, 1957595): sine loc. (Zmay 3, Jones s.n.
both at K), the latter specimen is likely from the Roseau
Botanic Garden where Jones was Director.
Two arguments have been put forward that Lam’s generic
name, Mastichodendron, was invalidly published. Cronquist
(1946b:246) said that it lacked a Latin description. However,
the taxon is not new but a transfer of Sideroxylon sect.
Mastichodendron Engler (1890, IV( 1): 144) by indirect reference
(through citation of Dubard, 1912:81). Van Royen
(1960:123) suggested that Lam regarded the name as provisional
but this does not seem to be true under the Code’s
definition (Art. 34.l(b)).

SCROPHULARIACEAE
Angelonia angustifolia Bentham, locally called “Mauve” or
“orchid,” is presumed to be only in cultivation and was
collected in Bataka (Hodge 3382) and Portsmouth (Nicolson

showy, purple flowers.
Torenia fournieri Linden ex Fournier was collected (Hodge
813) as a “weed in gravelly drain, probably escape” at Sylvania
