Marine Benthic Algae of the Houtman Abrolhos Islands, Western Australia
Marine Benthic Algae of the Houtman Abrolhos Islands, Western Australia. John M. Huisman School of Biological and Environmental Sciences, Murdoch University Murdoch, Western Australia 6150, Australia Abstract Recent collections and published records of marine benthic algae from the Houtman Abrolhos are catalogued. Two hundred and sixty species are included, comprising 32 species of green algae (Chlorophyta), 50 species of brown algae (Phaeophyta), and 178 species of red algae (Rhodophyta). Fifty-three species and four varieties are newly recorded for the Indian Ocean coast of Western Australia. The algal flora of the islands includes a mixture of typically temperate species (e.g. the kelp Ecklonia radiata (C. Agardh) J. Agardh) along with many species usually found at more northern latitudes in tropical waters (e.g. the red alga Trichogloea requienii (Montagne) Kiitzing). Introduction The Houtman Abrolhos is a group of mainly coral islands lying some 50-70 km offshore from Geraldton, Western Australia. They include the most southerly coral reefs in the Indian Ocean, and no doubt owe their presence to the influence of the Leeuwin Current, which brings warm waters from the tropics along the coast of Western Australia. The influence of the Leeuwin Current can be sporadic, and this juxtaposition of warm tropical water with the colder water more typical of these latitudes encourages unusual associations and contributes to a wide diversity of organisms (Hatcher 1991). The marine algae of the islands are poorly known, with only sporadic records appearing in the literature (e.g. Levring 1953; May 1946, 1951; Lucas 1926), mostly derived from collections made by the 'Percy Sladen Trust' expeditions of 1913 and 1915 (see Dakin 1918-1922) or collections made by school groups and presently lodged in the Adelaide herbarium. -
Taxonomic Assessment of North American Species of the Genera Cumathamnion, Delesseria, Membranoptera and Pantoneura (Delesseriaceae, Rhodophyta) Using Molecular Data
Research Article Algae 2012, 27(3): 155-173 http://dx.doi.org/10.4490/algae.2012.27.3.155 Open Access Taxonomic assessment of North American species of the genera Cumathamnion, Delesseria, Membranoptera and Pantoneura (Delesseriaceae, Rhodophyta) using molecular data Michael J. Wynne1,* and Gary W. Saunders2 1University of Michigan Herbarium, 3600 Varsity Drive, Ann Arbor, MI 48108, USA 2Centre for Environmental & Molecular Algal Research, Department of Biology, University of New Brunswick, Fredericton, NB E3B 5A3, Canada Evidence from molecular data supports the close taxonomic relationship of the two North Pacific species Delesseria decipiens and D. serrulata with Cumathamnion, up to now a monotypic genus known only from northern California, rather than with D. sanguinea, the type of the genus Delesseria and known only from the northeastern North Atlantic. The transfers of D. decipiens and D. serrulata into Cumathamnion are effected. Molecular data also reveal that what has passed as Membranoptera alata in the northwestern North Atlantic is distinct at the species level from northeastern North Atlantic (European) material; M. alata has a type locality in England. Multiple collections of Membranoptera and Pantoneura fabriciana on the North American coast of the North Atlantic prove to be identical for the three markers that have been sequenced, and the name Membranoptera fabriciana (Lyngbye) comb. nov. is proposed for them. Many collec- tions of Membranoptera from the northeastern North Pacific (predominantly British Columbia), although representing the morphologies of several species that have been previously recognized, are genetically assignable to a single group for which the oldest name applicable is M. platyphylla.

Hypoglossum Group (Delesseriaceae, Rhodophyta), with a Critique of Its Genera*
HELGOLANDER MEERESUNTERSUCHUNGEN Helgol6nder Meeresunters. 42,511-534 (1988) A reassessment of the Hypoglossum group (Delesseriaceae, Rhodophyta), with a critique of its genera* M. J. Wynne Department of Biology and Herbarium, The University of Michigan; Ann Arbor, MI 48109 USA ABSTRACT: A reassessment of the Hypoglossum group (Delesseriaceae, Rhodophyta), with a critique of its genera. Eight genera are assigned to the Hypoglossum group: Bartoniella Kyhn, Branchioglossum Kyhn, Chauviniella Papenfuss, DuckereBa Wynne, Hypoglossum Kfitzing, Phity- mophora J. Agardh, Pseudobrancln'oglossum Bodard, and ZeBera Martens. The circumscription of the group is emended to include forms with network-forming (ZeBera) and spirally twisted (Ducke- rella) thalli. The definition of the group is also modified to include members (e.g. some species of Hypoglossum) in which tetrasporangia are produced by primary cells as in the Caloglossa group. Exogenous branching, a distinguishing feature of the closely related Caloglossa group, never occurs in the Hypoglossum group. INTRODUCTION In a survey of the taxonomy of the red algal family Delesseriaceae, Wynne (1983) assigned seven genera to the Hypoglossum group. This assemblage was characterized by the sohd (non-reticulate) construction of its monopodial blades, restriction of its procarps to transverse pericentral cells, extension of all of its third-order cell rows to the blade margins, and production of its tetrasporangia in two or more layers. Criteria such as whether branching occurred from the midrib or from the blade margin and whether blades were essentially monostromatic or polystromatic throughout were employed to separate genera. Several new species of Hypoglossum and Branchioglossum have been described in recent years, leading to a need for reassessment of the circumscriptions of some of the genera. -

Claudea Elegans (Delesseriaceae, Rhodophyceae)
S. Afr. 1. BOL, 1987,53(4): 311 - 315 311 Ckludea elegans (Delesseriaceae, Rhodophyceae) in Natal, its fll'St record in the western Indian Ocean and Africa R.E. Norris Department of Botany, University of Natal, Pietermaritzburg, 3200 Republic of South Africa Accepted 7 April 1987 A specimen of the uncommon red algal genus, Claudea, was recently found in drift on the shores of northern Natal. Studies have been made on the development of its thallus and, although the plant is sterile, it is possible to positively identify it with the Australian species, C. elegans. This is the first record of the genus Claudea in Africa and the first report of C. elegans outside Australia. Taxonomic criteria are discussed that can be used to separate C. elegans from the other species described in the genus, C. multifida from Sri Lanka and C. batanensis from the Philippines. Conclusions are made regarding the close phylogenetic relationships of Claudea. 'n Eksemplaar van die ongewone rooi alg·genus, Claudea is onlangs in opdrifsels op die strande van noord·Natal gevind. Studies is uitgevoer op die ontwikkeling van die tallus en alhoewel die plant steriel was, was dit moontlik om dit sonder twyfel as 'n Australiese spesie, C. elegans te identifiseer. Hierdie is die eerste vermelding van die genus Claudea in Afrika en die eerste verslag van C. elegans buite Australie. Taksonomiese kriteriums word bespreek wat gebruik kan word om C. elegans van die ander spesies van die genus, C. multifida van Sri Lanka en C. batanensis van die Filippynse Eilande, te onderskei. Gevolgtrekkings word gemaak wat die noue filogenetiese verwantskappe van Claudea betref. -

Any opinions expressed in this memoir are those of the authors and do not necessarily reflect the views of the National Academy of Sciences. HAROLD CHARLES BOLD January 16, 1909–December 18, 1987 Elected to the NAS, 1973 Harold C. Bold, the C. L. Lundell Professor Emeritus of Systematic Botany at the University of Texas at Austin, died December 18, 1987. He was widely known for estab- lishing the classification system and systematics for green soil algae (Tetrasporales, Chlorococcales, Chlorosphae- rales). His research and that of his students showed that 1) virtually every soil, when moistened and placed in light, produces living algal taxa that grow and multiply; and 2) soil algae are structurally simple (unicells, colo- nies, coenobes) but have great diversity in cell form and reproduction, with complicated life cycles that can only be revealed through culturing and detailed microscopic study. Harold discovered that many features differentiate green soil algal taxa, such as cell size and shape, chloro- By Bruce C. Parker plast number and shape, presence of a pyrenoid, the mode and R.

The foundation in this area that Harold laid down over more than three decades represents a major breakthrough in the field of phycology, remains essentially unchanged today, and appears well supported by modern molecular phylogenetic approaches.
