MARINE ALGAE FROM THE TROPICAL ATLANTIC OCEAN: V. ALGAE FROM THE LESSER ANTILLES WILLUlI RANDOLPH TAYLOR Introduction In preparing a general account of the marine algae of the West Indies and neighboring coasts the writer has had many occasions to note apparent discontinuities of range, or ranges of conspicuous algae much less extensive that it seems reasonable to expect. One who knows the West Indian algal flora well discounts these deceptive ranges, but is nevertheless restricted in the range he can cite for species. The algae of very few places in the West Indies or nearby have been thoroughly studied; even those places that have been visited and the algae superficially studied are widely scattered. The marine algae of the Virgin Islands (while still the Danish West Indics) were thoroughly studied and described by B~rgesen (1913-20), and his papers are the most informative of any dealing with West Indian algae. Famous among the algal works on the Lesser Antilles are the books based on the collections of A. Schramm and H. Maze in Guadeloupe (Schrsmm and Maze 1865, 1866; Maze and Schramm 1870-77), the identifications having been made by the brothers Crouan, well-known phycologists of Brest. These are rare books in the original issues. The collections were made with great discern­ ment, but the identifications took little account of the great varia­ bility of many of these plants, and the publications while proposing scores of new species seldom provided descriptions of the plants. It appears that no definitive set of specimens was set aside; several institutions possess considerable series of them but the specimens under a given collection number are not always identical as to species. Hamel and Hamel..Joukov supplemented these works later (1929, 1931), as did Questel (1951). Grieve gave a brief list of Dominican algae (1909). The algae of Martinique have often been collected but reported only in scattered notes. A study of the algae of Barbados (Vickers 1905, 1908) yielded a rather limited list and a handsome atlas of selected Chlorophyceae and Phaeophyceae. The writer has reported on small collections from the Lesser Antilles in a few papers (1929, 1940, 1942). Lists 43 44 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM from several sources appear in the reports of the famous H.M.S. "Challenger" expedition, but they arc in part simply recapitulations of earlier-published accounts. The only comprehensive catalog of West Indian (including Lesser Antilles) algae is that of Murray (1888, 1889) which brings together all reports up to that date in one list, but unfortunately it is quite uncritical, including records Itlmost without question or verification, in particular those of Schramm and Maze without remark, even when their names are nomina nuda. The writer in his recent (1960) general work has attempted to select the most reliable reports from the Lesser Antilles as well as other West Indian and mainland eountries and to segregate those which arc doubtful. It is very satisfying to be able to report now on useful collections from the British Virgin Islands, Bnrbuda, Nevis, and Antigua, and even more substantial ones from St. Kitts, St. Lucia, and Grenada, which in tho very great majority of cases provide the first records of these plants from those islands, aud in several cases extend the known ranges of the plants along the cbltin. These collections did not come to hand in time to be studied and the records entirely incorporated in the general account mentioned above (Taylor 1960), though it was possible to introduce a very considerable number of the Grenada records and a few others of special interest. No general conclusions can be derived from these collections-they fill in gaps in our knowl­ edge but do not cbange our general picture of the West Indian algal flora. The materiltl from the Smithsonian-Bredin Caribbcnn Expeditions of 1958 and 1959 was submitted through the kindness of Dr. Fenner A. Chace, Jr., Curator of Marine Invertebrates, U.S. National Museum, and Dr. Waldo L. Schmitt, Emeritus Head-Curator of Zoology and one of the collectors on the expeditions. That (rom the Institute of Jamaica-Arnold Arboretum (Harvard University) Ex­ pedition was submitted by C. Bernard Lewis, Director of the Institute, on behalf of the collector, Mr. George R. Proctor and of Mrs. Lena Green, the curatorial assistant who prepared the material (or study. To all of these the writer is exceedingly grateful for the opportunity of studying the specimens. The first set of the Smithsonian-Bredin collection is in the U.S. National Museum, and tJu,t of the plants collected by Mr. Proctor in the Science Museum of the Institute of Jamaica. Localities As a large number of species are involved and as it is impossible in any case to designate the precise environment of individual speci­ mens, since they were grouped together in large jars, a general charac­ terization of each major station will be given below.

TAYLOR-MARINE ALGAE FROM LESSER ANTILLES 45 numbers for the Smithsonian specimens were supplied by the writer when mounting the plants for study; those with the Proctor specimens were assigned by the Science Museum. SMITHSONIAN-BREDIN CARIBBEAN EXPEDITION OJ' 1958 The algae of the Smithsonian-Bredin Expeditions were collected incidental to other tasks by various persons, particularly by Dr. Waldo L. Schmitt, to whose continuing interest in all living things of the shore, and generosity in contributing the plants for study, the writer has been deeply indebted for many years. Dr. Schmitt collected at most of the localities; Dr. Richard S. Cowan collected at Pigeon Island, St. Lucia, at some of the Barbuda localities, and Man-of-War Bay, Tobago, and Dr. Paul Denckla collected the algae at Antigua. Station 9-58.

Plants arising from very small, lobed, cushion-flbaped holdfasts, briefly terete below and often with 1-3 proliferations from the hold­ fast or the stalk, each expanding above to a 4-8 times irregularly dichotomous blade with a tapering base, the strap-shaped branches 4-10 mm. broad above the lower forkings, 1-2 mm. in the uppennost divisions, the tips rather acute, the margins entire. Blade thickness to 400-500 1', the cortex of one layer of small cells and the outer medulla of two layers, the inner ones rather large; medullary cavity small, loosely crossed by oblique thicker-walled filAments about 18-25 I' in diameter, and thinner-walled ones about 4.5-14 1'. Tetra­ sporangia scattered over the thallus, extending inward from tbe cortex, zonate, 30-38 I' in diameter, 45-55 I' long. Spennatangia widely distributed in patches over the surface. Cystocarps promi­ nent, marginal, with a parenchymatous core, the pericarps ostiolate, filamentous within, with some strands extending between the gonimo­ blasts to the sterile center; carposporangia produced in short centri­ petal series. Type in the U.S. National Herbarium, collected in Man-of-Waf Bay, Tobago, British West Indies, April 7, 1959, by Richard S. Cowan (No. 41). These plants agree in most respects with the description of Sarco­ diotheca, the only particular discrepancy lying in the restriction of the cystocarps to the margin, where they are strongly elevated. Individuals of west-coast species of the genus may, on occasion, have some of them along the margin. Since this is the first record of the genus in the western Atlantic in a family not represented there by many species, it is of particular interest. AgardhieUa tenera (J. Ag.)

Structurally showing an outer cortex of one layer of oval cells about 5 I'in diameter, 15 I' tall, below a firm gelat­ inous cuticle, and resting on a layer of small rounded ones. Outer medulla of abou~ 3 layers of thick-walled cells, the inner ones being very large, enclosing a filamentous central medulla, this being rather loose in the younger parts, dense near the base. Spermatangial plants several times irregularly to subdichotomously forked, to 1.0 cm. broad in the lower parts, or 1.5 cm. where subcuneate below a fork, the ultimate divisions more band-ilhaped and tapering, moderately to strongly erose-dentate. Cystocarpic plants with relatively broader, simpler and more irregular lobes rather than forking blades, these very strongly acuIeate-dentate above and, scattered Over the surface, bearing conspicuous superficial or elevated eystocarps 0.5-2.5 mm. in diameter, each with a thick 08tiolate pericarp, this parenchymatous without but with a filamentous lining. Gonimoblasts sW10unding a parenchymatous· core, this externally interrupted by groupe of fila­ ments spreading over the surface and bearing the sma.1l carpospor­ angia. Tetrasporangial plants not seen. Type in the U.S. National Herbarium, collected in Man-or~War Bay, Tobago, British West Indies, April 7, 1959, by Richard S. Cowan (no. 40, apermatangial and cystooarplo plant.). In the absence of tetrasporangial material and with too little cystocarpic material to permit a developmental study, the generic assignment of these plants must be considered tentative. They are far smaller and less broadly foliar than M.:f/crida Kylin, an ill-known plant although reported from Florida to Panama, and more regularly branched tban the type species, M. papuJ.osa (Mont.)
