96 FABACEAE SMITHSONIAN CONTRIBUTIONS TO BOTANY This element seems within the range <strong>of</strong> variable and widespread (neotropics and Africa) Andira inermis (W. Wright) Kunth ex A.P. Candolle. Bauhinia Linnaeus (Caesalpinoid) R. Wunderlin (USF) kindly reviewed this text and the determinations. Several species have been identified from collections made in the Roseau Botanic Garden: Bauhinia acum'nata? Linnaeus (Hodge 899 at GH) with large white flowers, Bauhinia racemsa Lamarck (Hodge 3905) with small white flowers, and Bauhinia romentosa Linnaeus (Hodge 902,1000 at GH) with large yellow flowers. All have 10 stamens. Two pink-flowered species are also expected in cultivation: Bauhinia purpurea Linnaeus (with 3 perfect stamens) and Bauhinia variegata Linnaeus (with 5 perfect stamens). Woody; leaves mostly 2-lobed or 2-foliolate, with palmate venation. 1. Cirrhiferous climber; corolla white to pinkish yellow; stamens 10 . . . . . , . . . , . , . . . . . B. guianensis 1.

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 <strong>Dominica</strong> 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 <strong>Dominica</strong>, 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 <strong>of</strong> 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 <strong>of</strong> an earlier validly published frCajanus.” Cajanus is in the nature <strong>of</strong> a now conserved later orthographic variant <strong>of</strong> 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. Anneslia tergemina (Linnaeus) Britton & Rose in North Amer. R., 1928,23:53. Madame ti poule. Shrub to 2 m; leaves bipinnate with 6 leaflets, 3 on each <strong>of</strong> 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 <strong>Dominica</strong> 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 (Chambers 2779, Ernst 1041, Hodge 3775, 3791, Webster 13289, Wilbur 7640), Layou to Roseau area (Eggers 519, Hodge 1305, Fairchild 2690, Stehle 6319). Howard (1988, 4:350) reported cultivated Calliandra huemutocephala Hasskarl on <strong>Dominica</strong> (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 <strong>Dominica</strong> (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, 4:457.-Nicolson et al., 1988:128. Dolichos maritimus Aublet, 1775:765. Dolichos obtusifolius Lamarck, 1786,2:295, non Jacquin, 1768. 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 <strong>Dominica</strong>: 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 <strong>of</strong> 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”) <strong>of</strong> the
