50 BIONONIA~AE SMITHSONIAN CONTRIBUTIONS TO BOTANY
fruit gourd-like, indehiscent; seeds unwinged, embedded in
Pulp.
Neotropics, often semi-cultivated, occasional in Dominica at
lower elevations: Bataca (Stehle 6369, 6372), sine loc. (Taylor

As elsewhere, the hard-shelled fruits of various shapes are
used to make containers (Hodge and Taylor, 1957:607).
Adjanohoun et al. (198555, pl. 22) reported usage to treat
wounds.

locality) at 500 m: Dleau Gommier (Nicolson 4035). Flowering

This genus is sometimes put in the Scrophulariaceae
(Armstrong, 1985).
Tabebuia Gornes ex A.P. Candolle
This genus is badly in need of revision. The taxa occurring in
Dominica are remarkably distinct in morphology and habitat,
perhaps more so than elsewhere. Because the taxonomy has
long been unsettled, nomenclature is remarkably entangled,
various authors using the same names for very different or
broad senses or different names for the same senses. We
decided to simply accept four more or less discrete taxa as
species for a basic classification and work out the nomenclature
(types) under that assumption.
The four species accepted are (1) Tubebuiu roseu (Bertoloni)
A.P. Candolle (1845,9:215), a native of Central America and
northern South America, which is cultivated in the Antilles,
including the Roseau Botanic Garden (Anonymous s.n. at K);
(2) Tubebuiu riparia (Rafhesque) Sandwith (1955:44), endemic
to Jamaica; (3) Tabebuia heterophyllu (A.P. Candolle)
Britton (1915:48), a (3-)5-foliolate pan-Antillean species
(excluding Jamaica); and (4) Tubebuiu pullidu (Lindley) Miers
(1863:199), a 1(-3)-foliolate species endemic to the volcanic
Lesser Antilles, but sometimes cultivated elsewhere.
We do not give formal synonymies for the first two species
since they are not known to occur naturally on Dominica. We
will give formal synonymies for the last two species that are
native to Dominica. However, an attempt to sort out all the
different misapplications of names used by various authors for
Dominican species results in such incomprehensible synonymies
that we decided to minimize the citation of names “sensu
auct.” and “pro park.” The following narrative account of
various names that have been used is an attempt to express their
disposition (typification) and to suggest the difficulties of
accounting for their misapplications.
The earliest legitimate name applicable to this group is
Bignoniu leucoxylon Linnaeus (1753:624). Sandwith
(1953:453; 195544) identified the Linnaean type with the
Jamaican endemic species (T. ripariu (Raf&sque) Sandwith);
the epithet is unavailable in Tubebuiu because of the existence
of the binomial I: leucoxyla A.P. Candolle, based on Vellozo
material.
Bignoniu leucoxylon Linnaeus (1763:870) is interpreted by
Sandwith (1953:453) as an illegitimate later homonym of B.
leucoxylon Linnaeus (1753:624). The type of the later
homonym is identified with what is here called T heterophylla.
