Baillieria sylvestris Aublet, 1775807.
Clibadiwn vargarii A.P. Candolle, 1836, 5506.4. Schulz in Uhan, 1911,
7:80.--Domin, 1930dz71.
Clibadiwn terebinthinacewn var. Weri A.P. Candolle, 1836,5506.
Clibadiwn badieri (A.P. Candolle) Grisebach, 1861:368.
Enivre, nivrage, kunami (Carib).
Similar to the above but leaf margins shallowly serrate to 5
entire and aborted ovaries of central flowers with tuft of long
hairs.
Northern South America into Lesser Antilles; lower elevations
of Dominica: Bells (Whitefoord 6145), Carib Reserve?
(Hodge 3199, cult. Clarke Hall (Nicolson 2025), La Ronde
(King 6362), La Plaine (Ernst 1584, King 6373), Salybia
(Stehle 6113).
Hodge and Taylor (1957:615) explained how Dominican
Caribs pound bundles of leaves and throw them into pools to
poison fish. At least one author is cited that believed this
species was brought from South America by Caribs. Nicolson
2025 reported that leaves are dried to make fish, insect, and rat
poison.
Condylidium King & Robinson
Condylidium iresinoides
Condylidiwn iresinoides (Kunth) King & Robinson, 1972b:881.
Eupatoriwn iresinoides Kunth, 1820.4:83.
Eupatoriwn iresinoides f. iniegrum Domin, 193Od:65, "integra."
Pubescent, sprawling herbaceous subshrubs; leaves opposite,
ovate, 3-veined, abruptly attenuated near base, darkglandular
dots beneath, margins * entire to sermlate; inflorescence
lax, often strongly divaricate; involucre of 15 unequal
bracts in 3 series of 5 bracts, inner ones not quickly deciduous;
receptacle flat, naked; florets tubular, few, 5-6; corolla
narrowly campanulate above; anther appendages slightly
longer than broad; style base with distinct enlargement above
nectary, style appendages linear, densely papillose; achenes
5-ribbed, base (carpopodium) strongly contorted.
Northern South American into Central America and West
Indies; occasional in Dominica on dry west coast: Gabriel
(Wilbur 8232), Mero (Ernst 1934).
Although I have not Seen the type (a Domin collection from
Macoucherie), the forma with entire leaves does not seem
different.
Conyza Lessing, nom. cons.
This genus is difficult. I have little faith in my key or
identifications.
1. Leaves very thinly pubescent and often with remote
marginal and midrib hairs only, entire (to * entire);
achenes glabrous . . . . . . . . . . . . . . C. canadensis
1. Leaves conspicuously pubescent, (* entire to) serrate;
achenes villous.
2. Leaves obovate or spatulate, rather abruptly narrowed to

Conyza apurensis
Conyza apurensis Kunth, 1820,4:73.-Cuatrecasas, 1969:221.
Erigeron spathulatus Vahl in West, 1793:303, "spathulatwn," non Conyza
spathulata Homemann.

Conyza subspathdata Cmquist, 1943:632.
Annual herbs; leaves alternate, pubescent, central and lower
ones obovate, usually strongly serrate; inflorescences tending
to be flat-topped (corymbose); involucral bracts in 2-3 series;
receptacle naked; ray-florets pistillate, lower tube 1 mm long,
tipped by an 2-toothed ligule (teste Cuatrecasas, 1%9:205),
which is surpassed by the 2 stigmas; achenes villous, f
flattened, tipped by a bristly 2-seriate pappus, outer series
minute.
Said by Cuaaecasas (1969:222) to have originated in Asia,
now a pantropical weed; in disturbed places of Dominica at
lower elevations: Clarke Hall (Chambers 2748), Grand Bay
road (Ernst 1588), La Chaudiere (Hodge 3548), Pont Casse
(King 6357), Roseau (Hodge 771).
