NUMBER 77 FABACEAE 91
Caesalpinia pulcherrima
Caesalpinia pdcherrima (Linnaeus) Swartz, 1791:166.-Hattink, 1974:50.
Poinciana pulcherrima Linnaeus, 1753:380.
Usually armed shrub to 3 m, not climbing: leaflets oblong, to
2.3 cm long; petals red, orange or yellow; pod oblong, flat,
glabrous.
New World tropics, widely cultivated in tropics for its showy
flowers; in Dominica naturalized on the dry west coast near sea
level and also cultivated inland Antrim (Gates Clarke s.n.),
Clarke Hall (Erst 1692), Grand Savanne (Wilbur 7654),
Macoucherie (Hodge 3720).
Cajanus A.P. Candolle, nom. cons. (Faboid)
Cajanus cajan
Cajanus cajan (Linnaeus) Millspaugh. 1900:53, “Cajan(us) cajan”.-Maesen,
198665.
Cytisus cajan Linnaeus, 1753:739.
Cujan cujan (Linnaeus) Huth, 1893:133, nom. inadmiss.
Pigeon pea.
Erect shrub to 3 m; leaves 3-foliolate, resin-dotted and
silvery beneath: flowers yellow inside and out or red outside:
pod flattened, obliquely depressed between the seeds.
Said to have originated in India (Maesen, 1986:76) but now
widespread in tropics; widely cultivated as hedge (and for
seeds) in Dominica, apparently escaping: Mt. Joy (Hodge
1299), Pickard River (Whitefoord 5243), Ridgefield (Hodge
2133), Roseau Valley (Nicolson 2140,2141, Whitefoord 4591),
South Chiltem (Hodge 1470), Walkers Rest (Chambers 2613).
Adjanohoun et al. (1985149, pl. 116) reported medicinal
uses.
Although I (1975390) argued for Huth instead of Millspaugh
as the first to make the combination, I now realize that
Huth’s “Cajun cajan” cannot be corrected to “Cajanus cajan”
because Cajun Adanson is a validly published generic name,
not a correctable misspelling of an earlier validly published
frCajanus.” Cajanus is in the nature of a now conserved later
orthographic variant of Cajun but is treated as a different name.
Calliandra Bentham, nom. cons. (Mimosoid)
Calliandra tergemina
Calliandra tergemina (Linnaeus) Bentham. 1844a:96.
Mimosa tergemina Linnaeus, 1753:517.

Madame ti poule.
Shrub to 2 m; leaves bipinnate with 6 leaflets, 3 on each of
the two pinnae (the lower pair being reduced to a single leaflet);
stamens >lo, showy, 2.5 cm long, white below and reddish at
end; fruits green with thickened red margin elastically opening
from end by recurving.
Guadeloupe south into northeastern South America; abun-
dant in Dominica in scrub along the west coast up to 350 m:
Cabrits to Colihaut (Hodge 2659, Nicolson 1897, Whitefoord
4422, Wilbur 8275, 8356), Grand Savanne to Layou River

Hodge 1305, Fairchild 2690, Stehle 6319).
Howard (1988, 4:350) reported cultivated Calliandra
huemutocephala Hasskarl on Dominica (with exclamation
mark, indicating he had seen material).
Canavalia A.P. Candolle, nom. cons. (Faboid)
Another species, Canavalia ensiformis (Linnaeus) A.P.
Candolle, also known as horsebean, has been collected from
Carib Reserve mulch plantings on Dominica (Hodge 3346).
The leaflets are ovate to elliptic, the pods 30-35 cm long, and
the seeds are white to ivory.
Canavalia rosea
Canavalia rosea (Swartz) A.P. Candolle, 1825,2:101.- Verdcourt in GiUett et
al. in Milne-Redhead & Polhill, 1971, Legum., 1(2):576.-Howard, 1988,

Dolichos roseus Swartz, 1788:105.
Dolichos rotundifolius Vahl, 1791,281.
Canavaliu maritima Du Petit-Thouan, 1813:80.Sauer, 1964:163.
Canavalia obtusifolia A.P. Candolle, 1825,2:404, nom. superfl. [incl. Dolichos
rotundifolius Vahl, 17911.
Canavalia maritima (Aublet) Urban, 1919a:400, non C. maritima Du
Petit-Thouars, 1813.-Adams, 1972:357.
Horse bean.
Perennial herbs with prostrate or scrambling stems; leaflets
pinnately 3-foliohte, orbicular to obovate, obtuse to emargi-
~te, 4-10 cm long; inflorescence nodose-racemose; calyx
2-lipped; corolla pink to magenta; stamens monadelphous to
middle; style glabrous; pods 5-15 cm x 2.5 cm; seeds oblong,
brown, marbled.
Tropical sea coasts; reported as common strand plant on
Dominica: Cabrits (Whitefoord 4026), Hatton Garden (Hodge
2961), Pointe Ronde (Hodge 2752), Tarou (Ernst ISOO), sine
loc. (Dudley s.n., Mar 1890).
There is controversy on the nomenclature of this species.
Adams (1972) accepted C. maritimu (Aublet) Urban, while
Gillett et al. (in Milne-Redhead and Polhill, 1971) accepted C.
rosea (Swartz) A.P. Candolle and Sauer (1964), and Lourteig
(1988b:394) accepted C. muritimu (Aublet) Thouars. The
solution to this problem lies in determining whether or not
Dolichos muritimus Aublet and Canavalia maritimu Thouars
are based on the same type. In my opinion, they are not.
Dolichos muritimus Aublet is solely based on Phmeolus
maritimus, fructu duro, semine variegato Plumier (as noted by
Lourteig, 1988b:393), typified by Plumier’s unpublished plate
99 in vol. 2 at Paris (cited by Aublet as “Mss. 99 t. 2”) of the
