collection as first Dominica record of I. veru.

Poix doux.
Small to medium tree to 30 cm dbh; leaflets usually in 2
pairs, 6-10 cm x 2-4.5 cm; inflorescence of axillary, spicate
racemes with pedicels to 0.5 mm long; pods 10 cm x 2.5 cm
and 1 cm thick (* terete), smooth.
Neotropics; common in Dominica in drier lowlands and
midlands, sometimes planted as hedge row: Calibishie (Hodge
3737), Carib Reserve (Hodge 3367, Stehlt! 6#37), La Chaudiere
(Hodge 3524), Coulibistrie (Emst 1393), Clarke Hall (Ernst
2154, Nicolson 21 79), Deux Branches (Hodge 3493), Dublanc

(Cooper 185, Hodge 612), Macoucherie (Hodge 3766), west of
Rosalie (Emst 1357), St. Aromant (Lloyd 564), Sylvania
(Hodge 611), sine loc. (Imuy 188 at K).
Hodge and Taylor (1957561) noted the use of this species to
shade cacao and coffee. A tea is made with the bark.
Leon (1966:284) pointed out that the type of Ingu fugifoliu
(Linnaeus) Bentham is from Barbados and is applicable to this
species (although I note that Linnaeus described the petioles as
marginate, i.e., winged) and reduced I. luurinu. However, he
overlooked the earlier publication of Ingu fugifolia G. Don
(1832) for a different species, which makes Ingu fugifoliu
(Linnaeus) Bentham (1875) an illegitimate later homonym.

obovate, curved and adnate to incurved keel; stamens 9+1;
stigma penicillate below terminal style; pods rough, flattened,

Probably native to Africa, now widely cultivated, apparently
escaped in Dominica: Baiac (Whitefoord 3826), between
Woodford Hill Estate and Calibishie (Erst 1837).

pairs, leaflets 10-20 per pinna, oblique at base and acute at
apex; heads terminal or axilIary: calyx 1 mm long, 5-toothed,
petals 5, linear; stamens 10,3x longer than petals; pods flat,
membranous, valves with raised margins: seeds ovate, transverse.
Neotropical but naturalized in Old World; western lowlands
and midlands of Dominica to 600 m: Cabrits (Hodge 3705),
Canefield (Kimber 1095), Dublanc (Whitefoord 4275), Morne

Lonchocarpus Kunth, nom. cons. (Faboid)
Trees or shrubs (ours); leaves pinnately 5-more compound,
stipels none; inflorescence * paniculate, the pedicels bifurcate
(2-flowered); calyx cupulate, truncate, or toothed; pod oblong,
usually flat, membranous to coriaceous, indehiscent.
1. Standard glabrous; leaves glabrous below, pellucidpunctate;
pod coriaceous . . . . . . . . L. benthamianus
1. Standard pubescent outside; leaves pubescent below: pod
papery . . . . . . . . . . . . . . . . . . L. heptaphyllus
Both these taxa have small, lanceolate bracts (or scars) near
the middle of the floral pedicels, which serves to distinguish
them from other taxa occurring in the Lesser Antilles that bear
orbicular bracts (or their scars) immediately below the flowers.
Mario Sousa (MEXU) is working on the genus but, as yet (Jan
1990), he has not published.
Lonchocarpus benthamianus

Lonchocarpus caritueus Urban, 1921b:156.
Savonette.
Shrub or small tree to 4 m; leaflets usually 7 or more,
glabrous, glandular-punctate, often acuminate and notched at
end, ovate, to 9 cm x 3 cm; calyx truncate; corolla pink to
lavender, >1 cm long: standard glabrous, with a green patch at
base; pods leathery, usually 1-seeded but when 2-seeded,
constricted between.
