100 FABACEAE SMITHSONIAN CONTRIBUTIONS TO BOTANY
Crotalaria lotifolia
Crotalaria lotifolia Linnaeus, 1753:349, "latifolia".-Senn, 1939:349.
Shrub with golden pubescence on young growth; leaves
3-fOfiOlate, glabrous above; racemes axillary, few-flowered,
pods with appressed pubescence.
Neotropics but scatter&, mid-elevations in northwest Dominica:
halfway between Colihaut and Syndicate Estate (Ernst
1991), a new record.
Crotalaria micans
Crotalaria micans Link, 1822,2:228.-Whdler & McLaughlin, 1980606.
Crotalaria anagyroides Kunth, 1824,6:404.4m, 1939:365.
Shrubs, upper branches striate; leaves 3-fOfiOlate, about 3x
longer than broad; calyx lobes considerably longer than calyx
tube, inflorescence elongate, terminal, pod appressed, puberulent.
South America, scattered in neotropics; introduced on
Dominica as a cover crop: Morne Nurseries (Bassett 14 at K),
sine loc. (Imray 201 at K).
Crotalaria pallida
Crotalaria pallida Aim, 1789,3:20.-Polhill, 1968:262.
Crotalaria mucronata hvaux, 1814:76.4enn, 1939:355.
Crotalaria striata A.P. Candolle, 1825,2130.
Crotalaria pallida var. obovata
Crotalaria pallida var. obovata (G. Don) Polhill, 1968:365.
Crotalaria falcata Vahl ex A.P. Candolle, 1825,2:132.-Adams, 1972:346.
Crotalaria obovaka G. Don, 1832,2:138.
Shrubby herb; leaves 3-foliolate; leaflets obovate, rounded to
emarginate, -6 cm x 4 cm; inflorescence terminal, calyx
pubescent, the lobes k longer than the tube, pod appressed,
pubescent.
Pantropical, scattered weed in Dominica: Carib Reserve
(Hodge 3343, Copt Hall (Basseft 4 at K), Delices (Whitefoord
3701), Dublanc (Hodge 2550), Fond Figues River (Ernst
1455), Goodwill (Wilbur 7581), Milton (Hodge 2922), Mome
Daniel (Kimber 1074), Pont Casd (Ems? 1240), Roseau
(Anderson s.n., 31 Aug 1965).
The Dominican specimens, indeed most West Indian
materials of this species (at US), fall into this variety. Typical
C. pallida, with larger leaflets broadest near the middle and
tapering to the apex, occurs mostly in Jamaica with a few
specimens from Cuba.
Crotalaria retusa
Crotalaria retrcsa Linnaeus, 1753:715.-Senn, 1939:327.
Glaucous subshrub with striate stems; leaves simple,
oblanceolate, rounded to retuse at apex; stipules minute,
deciduous; inflorescence terminal; calyx pubescent; pods erect
or spreading.
Pantropical; common field and roadside weed at low
elevations all over Dominica: Cabrit Swamp (Whitefoord
4053), Castaways Hotel (Stern & Wasshausen 2423, Dublanc
(Whitefoord 4284), Fond Figues River (Ernst 1454), Goodwill
(Hodge 603, Wilbur 7579), Marigot (Hodge 601), Pointe
Ronde (Hodge 2691), Ridgefield (Hodge 2141), Roseau
(Hodge 600), Roseau Valley (Fairchild 2823), Scotts Head
(Wilbur 7599), Sylvania (Hodge 1246), Wooten Waven
(Hodge 602), sine loc. (Cooley 8770).
Similar to C. spectubilis but lacking stipules.
Crotalaria spectabilis
Crotalaria spectabilk Roth, 1821 :34 l.Senn, 1939:326.
Yellow sweet pea.
Robust subshrub, leaf simple; stipules persistent, ovate to
deltoid, reflexed; inflorescence terminal; pods spreading to
declinate.
Asia, introduced into neotropics; common roadside weed in
lowlands of Dominica: Bibiay (DeFilipps 188), Coulibistrie
(Wilbur 8136), Fond Figues River (Ernsr 1241), Mome
Plaisance Estate (Whitefoord 4481), Ridgefield (Hodge 2142),
Wmten Waven (Hodge 605), sine loc. (Basset? 3 at K).
Similar to C. retusa but with persistent stipules. The Bassett
specimen was collected as C. sericea Roth (non Burman) as
introduced for a cover crop.
Crotalaria stipularia
Crotalaria stipularia Desvaux, 18 14:76.4enn, 1939:332.
Plants pubescent; leaves simple; stipules large, foliaceous,
decurrent below with free, incurving apices above; inflorescence
axillary, elongate but few-flowered.
South American species extending into Hispaniola; dry
lowlands of Dominica: Bellevue (Eggers 830), Grand Savanne
(Lloyd 835, Nicolson 1943), Soufri&re Village (Lloyd 432), sine
loc. (Bryant s.n. 1905 at K (misidentified as C. sagittalis L.)).
There are problems with the nomenclature of the infraspecitic
ma. Even their taxonomy is suspect, largely involving size
differences that may be more environmentally than genetically
determined.
Crotalaria verrucosa
Crotalaria verrucosa Linnaeus, 1753:715.--Senn, 1939:325.
Stem 4-angled, leaves simple, broadly ovate; stipules
persistent, lunate, deflexed; flowers blue (ours); inflorescence
terminal; pod many-seeded, stipitate.
Old World, introduced in New World; roadside weed in
Dominica: Imperial Road near coast (Lloyd 781), Lime Exp.
Station (Bassett 8 at K), Pringles Bay (Whitefoord 3738),
Roseau-Canefield (Hodge 604).
