Chrysymenia ventricosa (J.V. Lamouroux) J. Agardh 1842, p. 106
Figures 3–8 View FIGURES 3–8
TYPE LOCALITY: “In Mari Gaditano.Ad oras maris Mediterranei Galliae” (from sea around the Straits of Gibraltar, on shores of Spanish Mediterranean Sea)
TYPE MATERIAL: Mediterranean, no indication about collector, ( C 19/f 33), grey label ( Fig. 3 View FIGURES 3–8 ) is by the hand of Lamouroux; extra label written by J. F. Chauvin, his successor at Caen (Dr. Chantal Ballard, pers. comm.) mentions Fistularia ventricosa , a cornetfish ( Fistularia Linnaeus 1758 ). The independence of botanical and zoological nomenclature of F. fistularia is moot since the algal name was not formally described.
BASIONYM: Dumontia ventricosa J.V. Lamouroux 1813, p. 45 , pl. 4, fig. 6
SYNONYMS: Halymenia ventricosa (J.V. Lamouroux) C. Agardh 1822, p. 212
Chrysymenia digitata Zanardini 1863, p. 287
Chrysymenia ventricosa var. digitata (Zanardini) Hauck 1883, p. 159
MATERIAL EXAMINED: carposporophytic specimen, Cap Oullestreil, Côte des Albères, Pyrénées, Mediterranean France, 17.vii.84, coll. M.D. Guiry, Fig. 4 View FIGURES 3–8 . See Table 1.
GEOGRAPHIC DISTRIBUTION: Mediterranean. The occurrence of C. ventricosa outside this area is doubtful (Florida, Greater and Lesser Antilles, Southern Caribbean, Bermuda, Canary Islands, Venezuela, French Polynesia; see records in Taylor 1960, Littler and Littler 2000, Payri et al. 2000).
HABIT, VEGETATIVE AND REPRODUCTIVE STRUCTURE: The type specimen of C. ventricosa ( Fig. 3 View FIGURES 3–8 ) was not available for study, and only a dried herbarium specimen that lacked the basal part of a stipe and holdfast ( Fig. 4 View FIGURES 3–8 ) was analyzed. The thallus, about 17 cm tall, erect, terete to moderately compressed ( Figs. 3–4 View FIGURES 3–8 ), consists of a leading axis bearing alternate to opposite lateral side branches appearing sparsely but broadly pinnulate, giving the thallus a digitate appearance ( Figs 3, 4 View FIGURES 3–8 ). None of the side branches are constricted at their base ( Figs. 3, 4 View FIGURES 3–8 ). The thallus surface is completely corticated ( Fig. 5 View FIGURES 3–8 ), composed of two-to-three cortical cell layers of small roundish cells ( Fig. 7 View FIGURES 3–8 ) subtended by a layer of elongate, narrow subcortical cells and two medullary layers of large hyaline cells ( Fig. 7 View FIGURES 3–8 ). The elongate, periclinal subcortical cells are readily visible from a surface view ( Fig. 5 View FIGURES 3–8 ). Pyriform gland cells ( Fig. 6 View FIGURES 3–8 ) are pinched off singly and thallus inward from the peripheral cytoplasm of any unmodified subcortical or medullary cell ( Fig. 6 View FIGURES 3–8 ), with several gland cells of different sizes typically cut off from a single vegetative cell ( Fig. 6 View FIGURES 3–8 ). Ostiolate, hemispherical carposporophytes are scattered over the thallus surface ( Fig. 4 View FIGURES 3–8 ) and protrude from the surface. Mature carposporophytes reach about 0.8 cm in diameter, and lack an enveloping network of filaments around the globular mass of carposporangia ( Fig. 8 View FIGURES 3–8 ). Male and tetrasporangial thalli were not seen.
