NUMBER 77 VERBENACEAE 225
binomial in 1869. Later workers did not treat it as a hybrid but
at some infraspecific rank in one species or another. More
recently, Moldenke (letter of 22 Apr 1978) agreed with Voss’
disposal, an option mentioned by Moldenke (in Dassanayake,
1983,4:439). Moldenke (1980:100) appeared to regard this as
Clerodendrw umbellaturn Poiret. Pending a detailed study or
revision we maintain the predominant usage.
It is presumed that C. “thomonae” is named for a woman
whose last name was Thomson, which is augmented (thornsoniae)
under Art. 73.10 (ICBN). If demonstrably named for a
man, the epithet is correctable to thomsonii.

Bois cassave.
Finely tomentose shrub or tree to 8 m; twigs and branches
strongly 4-angled; leaves broad-elliptic, to 15 cm x 7 cm, apex
apiculate, base attenuate into 1-2 cm petiole; inflorescence a
narrow terminal panicle to 19 cm x 7 cm; pedicels 3 mm; calyx
1.5 cm, k truncate; corolla irregular, lavender, tube 1 cm, lobes
6 mm; fertile stamens 2, staminodes 2; drupe black, with 1
4-locular pyrene.
Central America and West Indies; common in Dominica
below 600 m: Antrim (Nicolson 1873, Bataca (Stehle 6413),
Cabrits (Whitefoord 3992), Carib Reserve (Hodge 3275, Taylor
19), Castle Bruce (Wilbur 7981), Fonde Hunte Estate (Whitefoord
4450), Grand Bay (Wilbur 7900), Grand Savanne (Stern
& Wasshausen 2453), Hampstead (Lloyd 602), L’Anse Noire
(Wilbur 7515), Salisbury (Wilbur 81 lo), Swamp Gutter (Hodge
867, Wilbur 8254), Sylvania (Hodge 868), Warner (Ernst
1956), Woodford Hill (Ernst 1550, Wilbur 8309). Flowering
vigorously June-July , fruiting August-October.
The fruit juice is used as a blue (red if boiled with lime) ink
or dye and the leaves are one of the ingredients in a tea to treat
pain of a retroverted uterus (Hodge and Taylor, 1957:600).

Shrub or small tree to 2.5 m; branchlets & 4-angled, with
occasional corky lenticels; petiole 1 cm; leaves ovatelanceolate,
to 14 cm x 3.5 cm, apices long-attenuate, bases
rounded; racemes unbranched, to 20 cm; pedicel 4 mm; calyx
to 5 mm, ribbed, k truncate but with 1 mm teeth, persistent in
hit; corolla irregular, lavender, tube 8 mm, lobes 5 mm; fruit
globular, yellow, enclosed by yellowish beaked calyx, 1 cm

Martinique; occasional in Dominica at mid-elevations or
montane (1200 m): Bernard Estate (Wasshausen & Ayensu
361), Morne Diablotins (Whitefoord 3927, 4434), South
Chiltern (Stern & Wasshausen 2491). Flowering June-July.
Lantana Linnaeus
Apomixis and polyploidy play a part in the evolution and
reproduction in this genus; workers relying on morphological
characters (Moldenke and others) have described large numbers
of taxa at specific and lower ranks. New approaches
(Stirton, 1977), utilizing ecology, cytology, as well as
morphology, are recognizing even more infraspecific taxa.
This treatment accords with Sander’s paper (1987) and
treatment in Howard (1989,6226). Sanders (1987) recognized
the unarmed higher elevation material with subglabrous leaves
as a distinct species, L. hodgei. Essentially he has redefined L.
camara of Dominica into three entities: high elevation L.
hodgei, and lower elevation L. urticifolia and L. camura with
many intermediates (regarded as hybrids). These three taxa are
difficult to recognize (requiring study under magnification of
hairs, their frequency, kinds, and distribution on various leaf
surfaces). Moldenke (1980:lOl) did not recognize L. urticifolia
as occurring on Dominica.
