208 SOLANACEAE SMITHSONUN CONTRIBUTIONS TO BOTANY Acnistus Schott Acnistus arborescens Acnistus arborescens (Linnaeus) Schlechtendal, 1832:67.-Hunziker. 1960:236.-Linle et al., 1974866, pl. 686.-Hunziker, 1982:85.

Large shrubs, twigs <strong>of</strong>ten tomentose; leaves ovate or elliptical, entire; flowers clustered on stems; pedicels slender, 1-2 cm long; flowers whitish, 9-14 mm long; berry orange, -8 mm across. Widespread but sporadic in neotropics; midlands <strong>of</strong> <strong>Dominica</strong> at edges <strong>of</strong> woods and forming roadside thickets, 150-750 m: Colla Anglais (Hodge 1148, Webster 13430), Delices (Whitefoord 3770), Freshwater Lake area (Chambers 2685, Eggers 803, Ernst 1086, Hodge 1791, 2030, Lloyd 126, Smith 10288, Wasshuusen & Ayensu 318, Wilbur 7447), Soufribre road (Burch 1339), South Chiltern (Hodge 1531), Syndicate (Ernst 2010), sine loc. (Cooper 42). Browallia Linnaeus Browallia americana Browallia americana Linnaeus, 1753:63 1.-D’Arcy, 1973:576. Browallia demirsa Linnaeus, 1759a:1118. Herbs; leaves ovate or elliptic, entire; flowers solitary, pedicels 2-6 mm long; flowers blue or violet, rarely white, salverform, the limb 1-2 cm across; capsule -9 mm long, enclosed by the ribbed calyx. Neotropical weed; common in <strong>Dominica</strong> on roadsides and in fields: Bellevue (Hodge 2351), between Fern Villa and Mome Gay (Hodge 2209), between Fond Baron Estate and Pichelin (Ernst 1583, Laudat (Lloyd 239), Layou River (Chambers 2797, Ernst 2180), Lisdara Estate (Hodge 796, 797), Montpelier (Lloyd 588), Morne Colla Anglais (Hodge 1028), Soufriere (Lloyd 476), Sylvania (Cooper 83), Syndicate (Ernst 1998, Whitefoord 4463), Wallhouse (Eggers s.n. in 1880), sine loc. (Eggers 507). Brugmansia Persoon Brugmansia suaveolens Brugmanria suaveolens (Willdenow) Berchtold & Presl, 1823, 1:45.- Lockwood, 1973:281. Datwa suaveolens Humboldt & Bmpland ex Willdenow, 1809, Enum., 227.-Bri~tol, 1966240. Shrubs; leaves ovate, entire; pedicels solitary, stout; flowers pendulous, large and showy; calyx tubular, 5-pointed; corolla to 30 cm long, broadly tubular, white or pink. Native <strong>of</strong> South America, widely cultivated as an ornamental, sometimes escaping; known in <strong>Dominica</strong> as an escape: Wcllhouse (Eggers 622), “along banks <strong>of</strong> a river, 2000 ft” (Jones 12 at K). Separation <strong>of</strong> the woody Brugmansia from herbaceous Datura was justified by Lockwood (1973) on the basis <strong>of</strong> bits and seed coat. Plants from cultivated stocks are not known to set fruit. Adjanohoun et al. (1985:177, pl. 144) reported (as Datura suaveolens) that the dried flowers, smoked in cigarettes, are hallucinogenic. Brunfelsia Linnaeus Brunfelsia americana Brunfelsia americana Linnaeus, 1753:191.--Little et al., 1974:868, pl. 687.-Plowman in Hawkes et al., 1979:479. Brunfelsia fallax Duchassaing ex Grisebach, 1857:242. Rain tree, empoisonneur, peep zombie. Glabrate shrub or small tree; leaves thick, entire, blunt or round-tipped; petioles short; pedicels solitary, short and stout; calyx 5-9 mm long, blunt-tooth&, corolla showy, white but fading yellow, fragrant, salverform, the tube 3-7 cm long, the limb 2-5 cm across; berry round, 1-2 cm across, yellow, thick-skinned. Hispaniola to Trinidad; in <strong>Dominica</strong> mostly at lower elevations on windward coast: Carib Reserve area (Hodge 3298, Stehle 6375, 6382, 6643, 6710), between Capucin and Bellevue (Wasshausen & Ayensu 384), Cabrits (Hodge 3720 at US), Hatton Garden (Hodge 3183, 3209), road to Laudat (Burch 1344A), Melville Hall (Ernst 1679), Pagua Bay (Burch 1401, Wilbur 7532), Roseau Botanic Gardens (Hodge 1001), Sophia Bay and Walkers Rest (Chambers 2623), Vieille Case (Beard 663). Hodge and Taylor (1957503) reported the ripe berries were used by the Caribs as a poison. The name Brunfelsia americana has been misapplied to several different horticultural species that have longer corolla tubes, shorter corolla limbs, and different calyces. Some may be cultivated on <strong>Dominica</strong>. Capsicum Linnaeus Capsicum annuum Capsicum annuum Linnaeus, 1753:188.-D’Arcy & Eshbaugh, 1974:98. Capsicum frutescenr Linnaeus, 1753:189. Capsicum annuum var.frutescens (Lumaeus) Kuntze, 1891,2:449. Capsicum baccatum sensu Grisebach, 1862:436. non Linnaeus. Red pepper, piment, bud pepper. Slender, erect or sprawling herb or weak shrub; leaves ovate, entire, sparingly pubescent; pedicels mostly solitary, stiff; calyx truncate or with minute (
NUMBER 77 SOL~VACEAE 209 collected in <strong>Dominica</strong> in woodlands: Layou River valley (Ernst 1264, Soufriere (Lloyd 439, South Chiltern (Hodge 1556); seen around houses but not collected. Cultivated by Caribs for relish, seasoning, and medicinal purposes (Hodge and Taylor, 1957:603). Adjanohoun et al. (1985:175-177, pl. 142-143) reported medicinal uses for both Capsicum annuum and C. frutescens. Plasticity and selection have largely obscured relationships in cultivated peppers. Characters <strong>of</strong> fruits, long used to separate species, have proven unreliable. Recent workers (as Howard, 1989, 6:271) have separated Capsicum annuum (bell pepper) from C. frutescens (shrubby chili pepper), and their wild counterparts, including Capsicum annuum var. aviculare (Dierbach) D’Arcy & Eshbaugh. More recently, workers have found the wild progenitors <strong>of</strong> the two cultivated peppers to be largely inseparable and recognize only one species, C. annuum. The <strong>Dominica</strong>n collections seen, all wild, correspond to C. annuum var. frutescens (Linnaeus) Kuntze. Two other peppers are probably cultivated in <strong>Dominica</strong>: Capsicum annuum var. annuum, the common garden bell pepper, and Capsicum chinense Jacquin, a pepper with thick-walled, <strong>of</strong>ten pink fruits. Cestrum Linnaeus The following species, both with showy inflorescences to 10 cm long, are presumed to be only cultivated: Cestrum diurnum Linnaeus (Little et al., 19745376, pl. 691), with clustered flowers and corolla
