Brassica Linnaeus
Brassica oleracea Linnaeus, the cabbage, is cultivated in
Dominica and sold in markets.
Brassica juncea
Brassica juncea (Linnaeus) Czemajew, 1859:8.-ALShehbaz in Howard,
1988, 4:278.
Simpis juncea Linnaeus. 1753:668.
Sinapis integrifolia Vahl in West, 1793:296.
Sinapis integrifdia Willdenow, 1804, Hort. 1:14, non Vahl.
Sinapis cuneifolia Roxburgh, 1832.3:121.
Brassica willdenovii Boissier, 184288.-Adams, 1972:308.
Brassica integrifolia Ruprecht. 1860:96.-Bailey. 1922:95.
Brassica iniegrifolia (Vahl) Schulz in Urban, 1903,3:509, non Ruprecht.-
Schulz in Engler, 1919, IV.105 (Heft 70):57.
Wild mustard.
Leaves serrate, not amplexicaul, upper leaves oblong or
wider near apex.
Presumed originally Asiatic, now widely cultivated and
escaping; field weed in Dominica: South Chiltem (Hodge
1504). Dried leaves used as tobacco substitute.
Specimens with lower leaves not or scarcely divided are
commonly treated as a distinct species, a view not accepted
here. This concept is commonly called Brassica integrifolia or
B. willdenovii.
There are questions about the author citation of Brassica
juncea. Many workers cite Cosson (1859:605), who read his
paper on 16 Aug 1859; publication was certainly late in 1859,
at best. I follow Tutin et al. (1964, 1:337) in accepting
Czemajew’s publication as valid and prior to Cosson’s. The
romanization as Czemajew is questionable. A literal transcnption
would be Chemyaev. Tscherniaieff was used by Pritzel.
Again I follow Tutin et al. (1964), assuming that the rather
irregular romanization was used by the author.
Lepidium Linnaeus
Lepidium virginicum
Lepidiwn virginicwn Linnaeus, 1753645.
Pepper grass.
Small herb with white petals; stamens usually 2; beak of fruit
absent.
North American, now widely distributed; a weed of flower
gardens and waste places in Dominica: Cabrit Swamp
(Whitefoord 4085), Clarke Hall (Ernst 1272), South Chiltern
(Hodge 1515, Nicolson 2170).

Rorippa nasturtium-aquaticwn (Linnaeus) Hayek, 1905:22.-Green, 1962:32.
Watercress, cresson.
Aquatic herb with succulent, edible stems and leaves; fruit
beak short.
Old World, widely naturalized; in Dominica growing beside
Gaulettre River in Carib Reserve: (Hodge 3322).
The literature is full of articles on watercress because its
generic disposition is debatable. Some authors include it in
Rorippa. Recent major publications on Rorippa (Jonsell, 1968,
and Stuckey, 1972) separate Nasturtium from Rorippa and
regard it as a separate genus with one diploid species, N.
@cinale, and a tetraploid taxon commonly recognized as a
distinct species, N. microphylla.
The logical combination, Nasturtium nasturtium -aquaticum,
is specifically cited in the ICBN (Art. 23.4) as a tautonym.
Nasturtium aquaticum Garsault (1764,3:241, pl. 403) is not
validly published under Article 23.6(c) (ICBN), because
