SMITHSONIAN CONTIUBUTIONS TO BOTANY
New World, even though Sauer (1964:163) lectotypified it on
“Phaseolus maritimus purgans . . . Pluk. Phytogr. t. 5 1, fig. 2.
1691,” a South Indian element from Bisnagar (more correctly
Vijayanagar or Victory City), an element not mentioned by
Aublet or Plumier. Canuvalia maritima Thouars may be
typified by material from Madagascar or Reunion, but it clearly
was considered by the author to be identical with Katu tsjandi
(or Canavali in Hindi) Rheede (1688, 8:83, pl. 43) and
Phaseolus maritimus purgans . . . Pluk. Verdcourt’s lectotypification
on Plukenet’s illustration seems acceptable. The
synonymy hinges on Dolichos maritima Aublet (New World)
and Canavalia maritima Thouars (Old World) being nomenclaturally
heterotypic, albeit taxonomically conspecific.
Centrosemu (A.P. Candolle) Bentham, nom. cons. (Faboid)
Twining vine with 3-fOliOhte leaves; stipules and stipels
persistenc nodes of inflorescence not swollen; flowers subtended
by striate bracteoles, large, with standard spurred near
base; stamens 9+1; style glabrous; pod linear, flattened but
twisted in age, the 2 valves thick-edged.
Centrosema plumieri (Persoon) Bentham was attributed to
Dominica by Vklez (1957:99) on the authority of Britton and
Wilson (1924, 5:412), who reported Bradburya plumieri “St.
Kitts to Trinidad.” This species has conspicuous bracteoles in
flower that are glabrous and longer than the calyx. The pods are
larger and with definite wings about one-third from each valve
margin. Howard (1988,4:459) listed this species for Dominica
with an exclamation mark.

long as other deltoid teeth; pod 5-7 mm broad
