A Taxonomic Review of Hawaiian Gelidiales ( Rhodophyta )

The present study reviews most collections of Gelidiales known from Hawaii. Three genera, each one including four species, are recognized among nearly 350 specimens examined. The genus Gelidiefla is represented in Hawaii by G. acerosa (Forsskal) Feldmann et Hamel, G. adnata Dawson, G. machrisiana Dawson, and G. myrioclada B0rgesen. The genus Gelidium includes G. crinale (Turner) Lamouroux, G. p...

Crusticorallina gen. nov., a nongeniculate genus in the subfamily Corallinoideae (Corallinales, Rhodophyta).

Molecular phylogenetic analyses of 18S rDNA (SSU) gene sequences confirm the placement of Crusticorallina gen. nov. in Corallinoideae, the first nongeniculate genus in an otherwise geniculate subfamily. Crusticorallina is distinguished from all other coralline genera by the following suite of morpho-anatomical characters: (i) sunken, uniporate gametangial and bi/tetrasporangial conceptacles, (i...

Universal plastid primers for Chlorophyta and Rhodophyta

To date, the majority of molecular genetic studies in algae have utilized a fairly limited range of markers such as the plastid rbcL gene and spacer, the mitochondrial cox2-3 spacer or the nuclear ribosomal DNA and spacers. The lack of available markers has been particularly problematic in studies of within-species variation. Whilst microsatellites are now being developed in many algal species,...

Observations on Two Species of Liagora ( Rhodophyta )

ALTHOUGH THE ONTOGENY of the cystocarp has been studied in a number of species of the nemalionalean genus Liagora (Butters, 1911; Bl1lrgesen, 1915-20, 1927; Kylin, 1930; Yamada, 1938; Levring, 1941; Abbott. 1945), gaps still exist in our knowledge of the development of this structure. Thus, little precise information is at hand concerning the place of origin of the so-called involucral filament...
