This is a floristic treatment of benthic marine red algae (Rhodophyta) in the order Rhodymeniales which occur in British Columbia and northern Washington. The following 12 species in 9 genera are recorded and illustrated: Botryocladia pseudodichotoma (Farlow) Kylin, Fauchea fryeana Setchell, Fauchea laciniata J. G. Agardh, Faucheocolax attenuata Setchell, Fryeella gardneri (Setchell) Kylin, Gastroclonium subarticulatum (Turner) Kützing, Lomentaria hakodatensis Yendo, Minium parvum Moe, Rhodymenia californica Kylin, Rhodymenia pacifica Kylin, Rhodymenia pertusa (Postels et Ruprecht) J. Agardh, and Rhodymeniocolax botryoidea Setchell. Rhodymenia stipitata Kylin is treated as a taxonomic synonym of Rhodymenia pertusa. Previous reports of Coeloseira parva Hollenberg from British Columbia and Leptofauchea auricularis Dawson and Leptofauchea pacifica Dawson from northern Washington were based on misidentifications or could not be confirmed. Also provided is a historical background of the Rhodymeniales. Keys to and descriptions of local taxa (at the ordinal, familial, and generic levels), as well as information on synonyms, location of type specimens, type localities, and what is known about the life histories, distribution, seasonality, and habitats of all local taxa, are provided. Rhodymenialean species occurring in British Columbia and northern Washington which are also reported in the California flora are listed, as are those which are restricted to one or the other flora. References are given and representative specimens cited that document our concepts of the taxa and their morphological variability, seasonality, and geographical distributions.

This is a floristic treatment of benthic marine red algae (Rhodophyta) in the order Palmariales that occur in British Columbia and northern Washington. Seven species (including one new species of Palmaria) in four genera are recorded as follows: Halosacciocolax kjellmanii Lund, Halosaccion glandiforme (S. G. Gmelin) Ruprecht, Palmaria callophylloides Hawkes et Scagel, sp. nov., P. hecatensis Hawkes, P. mollis (Setchell et Gardner) van der Meer et Bird, Rhodophysema elegans (P. L. et H. M. Crouan ex J. Agardh) P. S. Dixon, and R. georgii Batters. Rhodophysema minus Hollenberg et Abbott is treated as a taxonomic synonym of R. elegans. An historical background of the Palmariales is provided. Also provided are revised circumscriptions of the family Palmariaceae and genera Palmaria, Halosaccion, and Rhodophysema based on recent life-history studies by other workers that demonstrate the presence of sexual reproduction in several palmarialean taxa. Keys to and descriptions of taxa (at the ordinal, familial, generic, and specific levels), as well as information on synonyms, location of type specimens, type localities, and what is known about the life histories, distribution, seasonality, and habitats of all taxa, are provided. References are given, and representative specimens are cited that document our concept of the taxa and their morphological variability, seasonality, and geographical distributions.

The benthic marine algal order Gigartinales (Rhodophyta) is introduced, and a key to the families found between Cross Sound, Alaska, and northern Washington is provided. The family Dumontiaceae is monographed. Ten of 16 currently recognized genera and 14 of some 48 recognized species are described and illustrated: Constantinea rosa-marina (Gmelin) Postels et Ruprecht, C. simplex Setchell, C. subulifera Setchell, Cryptosiphonia woodii (J. G. Agardh) J. G. Agardh, Dilsea California (J. G. Agardh) Kuntze, Dumontia contorta (Gmelin) Ruprecht, D. simplex Cotton, Farlowia mollis (Harvey et Bailey) Farlow et Setchell in Collins, Holden, et Setchell, Neodilsea borealis (Abbott) Lindstrom, N. natashae Lindstrom, Orculifilum denticulatum Lindstrom, Pikea californica Harvey, Thuretellopsis peggiana Kylin, and Weeksia coccinea (Harvey) Lindstrom. Farlowia compressa J. G. Agardh is recognized as a taxonomic synonym of F. mollis, and Pikea robusta Abbott as a taxonomic synonym of Pikea californica. Vegetative keys to the genera and species of the family are also included. Basionyms, synonyms, type specimens, type localities, and what is known about life histories, distributions, phenologies, and habitats of the species are given. Representative specimens are cited.

Eleven new taxa are described from California; two species, in addition, have new varieties added to them; and two species are given new circumscriptions to include a number of entities previously known under other names. New species are described in Percursaria (Chlorophyta), in Feldmannia (Phaeophyta), and in eight genera (Membranella, Porphyra, Rhododiscus, Peyssonelia, Prionitis, Blinksia, Besa and Rhodoglossum) of Rhodophyta. Two monotypic genera of Rhodophyta are described for the first time. One, Membranella nitens, is added to the Bangiales, and the other, Blinksia californica, is the type for a new family, the Blinksiaceae (Gigartinales). Half of the species of red algae are crustose non-corallinaceous species.

This is a floristic treatment of the gigartinalean families Caulacanthaceae and Plocamiaceae that occur in southeast Alaska, British Columbia, and northern Washington. Caulacanthaceae is represented by one genus, Caulacanthus Kützing, and one species, the type, C. ustulatus (Mertens ex Turner) Kützing, whereas Plocamiaceae is represented by two genera, Plocamiocolax Setchell, including the type species, P. pulvinata Setchell, and Plocamium Lamouroux, including three species, P. cartilagineum (L.) Dixon, P. oregonum Doty, and P. violaceum Farlow. For each species, we provide a description of its habit and life history, vegetative and reproductive morphology, habitat and seasonality, and list its global and local distributions and the representative specimens examined. Keys are provided to genera and species where appropriate. The habit and salient vegetative and reproductive features that can be used to distinguish the taxon in the local flora are illustrated. Emended diagnoses are provided for the family Caulacanthaceae, for the genus Plocamiocolax, and for the species Plocamiocolax pulvinata and Plocamium oregonum. Reasons are given for not recognizing the northeast Pacific specimens of Plocamium cartilagineum as a distinct subspecies. Plocamium tenue Kylin is considered a synonym of P. violaceum. A neotype is designated for Plocamiocolax pulvinata. Lectotypes are designated for P. pacificum Kylin and for P. tenue Kylin.

Tetralophozia setiformis is a widespread species occurring usually without organs of sexual and asexual reproduction. Gemmae of Tetralophozia setiformis were observed for the second time in Russia and Eurasia in the Northern Urals, Komi Republic. They form compact masses over upper leaves. The compact masses consist largely (70 %) of immature gemmae. Description of gemmae and gemmiparous shoots from the Northern Urals and their comparison with those from the other known localities, namely British Columbia (Canada) and the Murmansk Region (European Russia) were carried out. The gemmiparous plants of T. setiformis from the Northern Urals have approximately the same width as plants without gemmae but they are shorter. The leaves of gemmiparous plants from the Northern Urals are similar to leaves of gemmiparous plants from British Columbia. The leaf shape in upper part of the gemmiparous shoots varies from the typical to ± modified from gemmae production. These leaf shape transitions include reduction of leaf size and lobe number from 4 to 2–3, suppression of development and disappearance of characteristic teeth at the base of sinus. Gemmae size (17 × 22 μm) of plants from the Northern Urals is within variability recorded for plants from the Murmansk Region and British Columbia.

Much has been written of William Duncan, "the Apostle of Alaska", who came to the coast of northern British Columbia in 1857 as a missionary to the Tsimshian Indians. Although he deplored it, in the course of his sixty years' residence in this area controversy raged around him as a result of his clashes with church and state, and his work has been the subject of numerous investigations, both public and private. His enemies have called him a tyrant and a ruthless exploiter of the Indians under his control; and there are men still living who find a disproportionate amount of evil in the good that he did, especially during the declining years of his long life. On the other hand, he has had ardent and articulate supporters who have written numerous articles and no less than three books in praise of his self-sacrificing ideals and the soundness of his program for civilizing the Indian.

Paepalanthus decorus was described by Delia Abbiatti from a single collection of individuals made by Carlos Luis Spegazzini in Uruguaiana, Rio Grande do Sul state, Brazil, deposited at the La Plata Museum. The species is known only from the type specimens, which were unusual for being collected far to the south of the distribution of the other species included in P. sect. Diphyomene. In recent nomenclatural treatments for P. sect. Diphyomene, P. decorus was disregarded, remaining known only from its original publication. Here, we critically evaluate the protologue, type specimens, and the vegetative and floral morphology of this species. As a result, we propose its synonymization under P. flaccidus. A detailed comparison of these species is provided, along with comments on typification, with a lectotype designated for P. flaccidus.

At the present time, when our fin de siècle knowledge of “general paralysis” enables us to recognize under that generic term many types of the disorder, and when the relation between it and syphilis continues a rather vexed question, little apology is needed for introducing to notice the following cases. They illustrate unmistakably some of the instances in which syphilis is solely responsible for what. Is termed by Dr. Savage” A process of degeneration which ultimately produces the ruin we recognize as general paralysis.”∗ Whatever may be hereafter formulated from the present evolutionary crisis in the history of the disorder there can be but little doubt that syphilis will be one of its most intimate and important relations. The story of its methods is briefly sketched in the following two short life-histories—in one asserting itself in the offspring of its victims by right of impure heredity, in the other carrying death direct into the vital centres by the force of its malignant virus.

Scorzonera amasiana Hausskn. and Bornm. was described from type specimens collected by J.F.N. Bornmueller in 1889 but it was not collected again until 1993, when it was found near Amasya, Turkey. Populations of S. amasiana were quite small at that limited locations and were vulnerable to human impacts. Therefore, suitable conservation strategies should be developed immediately in order to protect the species from probable extinction. Here, an additional three small populations are reported. Brief history, morphology, habitat and ecology of this endemic species have been discussed. Its current conservation status was reevaluated with respect to the latest IUCN criteria. A key to distinguish it from the other closely related Turkish species is also provided and its distribution map is appended.   Key words: Endangered, Rediscovery, Scorzonera, Turkey DOI = 10.3329/bjb.v36i2.1502 Bangladesh J. Bot. 36(2): 139-144, 2007 (December)
