黔西北两铜矿4种藓类植物重金属元素分析

坝口铜矿和长箐沟铜矿是峨眉山玄武岩型铜矿。利用3种光谱仪对卷叶丛本藓（Anoectangium thomso-niiMitt.）、酸土藓[Oxystegus cylindricus（Brid.）Hilp.]、硬叶扭口藓[Barbula rigidula（Hedw.）Mild.]和齿边异齿藓[Regmatodon serrulatus（Dozy et Molk.）Bosch et Lac.]及其基质中的Cu、Zn、Ca、Mg、Cd、Pb、Hg和As8种元素进行测定及分析,并计算出富集系数。结果表明,两铜矿Cu、Zn、Cd和Hg的背景值均超标,特别是Hg和Cu的平均含量分别是其标准值的10.28倍和2.33倍。长箐沟铜矿受Hg污染较重,坝口铜矿比长箐沟铜矿含Cu高。Cu-Cd、Zn-Ca、Ca-Pb和Hg-As均在0.05水平显著相关,Zn-Pb在0.01水平显著相关。Cu-Cd、Zn-Pb和Hg-As均产生协同效应。Zn-Ca和Ca-Pb均产生拮抗效应。富集系数有显著意义。4种藓类植物对Cu、Cd和Pb的吸收能力均是同一水平,可以作为指示植物,构成藓类植物组合来鉴别富集Cu、Cd和Pb的矿区。可利用卷叶丛本藓作为特征植物降低矿区As的污染。

A revision of the moss genus Sciaromium (Mitt.) Mitt. I. General remarks and the section Aloma Dusén

Abstract

The generic name Sciaromium (Mitt.) Mitt. that was originally used as a sectional epithet in Leskea is synonymous with Echinodium Jul E. madeirense Jur. [= E. spinosum (Mitt.) Jur.] is selected as the lectotype of the genus Echinodium. A historical review of taxonomic and nomenclatural problems in Sciaromium is provided and taxa that had previously been excluded from this genus are briefly discussed. Sciaromium flavidulum Dusén is a Eurhynchium and the combination E. flavidulum (Dusén) Ochyra is made. Sciaromium sect. Aloma Dusén is synonymous with Eurhynchium since E. flavidulum serves as the type species of this section. The taxonomic position of S. gracile Dusén is discussed and this species is considered synonymous with Amblystegium chilense Lor., which is transferred to Pseudoleskea and the appropriate new combination P. chilensis (Lor.) Ochyra made. Type specimens of S. bellii Broth., S. elimbatum Broth. & Watts and S. forsythii Broth. in Broth. & Watts are briefly described and illustrated; these species are reduced to synonymy with the polymorphic Cratoneuropsis relaxa (Hook. f. & Wils.) Fleisch. in Broth.     

Aloina and Aloinella (Bryopsida, Pottiaceae) in northern Argentina

Except for a robust habit, two specimens ofAloina collected in northern Argentina are morphologically similar and are tentatively attributed toA. rigida (Hedw.) Limpr. This represents an addition to the moss flora of Argentina. In addition, two specimens ofAloinella represent significant findings: one shows features that agree with those given in the protologue forA. galeata (Müll. Hal.) Broth. and is treated here asA. galeata var.galeata to show the relationship toA. galeta var.andina (Delgad.) Delgadillo & Schiavone stat. nov.; the other belongs inA. cucullifera (Mitt.) Steere, a new record for Argentina. A key to the known species ofAloinella with updated ranges is included.

New records of bryophytes from the Canary Islands

Abstract

Two members each of the Adelanthaceae and Schistochilaceae and three of the Porellaceae are recorded from Mulanje Mountain, of which Adelanthus lindenbergianus (Lehm.)

Development of gametophores from isolated protoplasts of the mossAnoectangium thomsvnii Mitt.

Summary Protoplasts of the mossAnoectangium thomsonii Mitt. were isolated from preplasmolyzed protonemal filaments, grown in suspension cultures, after the digestion of the cell wall by the enzymes cellulase and macerozyme or driselase. Driselase was more effective than cellulase and macerozyme. After purification these protoplasts were plated in the form of small agar drops in modified Kofler's medium without hormones and incubated in the dark at 26 ± 2 °C. Cell walls regenerated within three days and cell divisions started seven days after the initiation of the cultures. When the regenerants were transferred to normal protonemal culture medium and illuminated by 3,000 lux continuous light, a multi-cellular protonema developed which formed leafy gametophores on salicylic acid supplemented medium.

Bosch &; Lac., C. pseudogracilis Card. &; Dix. with C. goughii (Mitt.) Jaeg., C. caudatus (C. Müll.) Mont., C. reduncus (Reinw. &; Hornsch.) Bosch &; Lac. and C. trachythecius (C. Müll.) Jaeg. with C. comosus (Reinw. &; Hornsch.) Bosch &; Lac., C. herzogii Broth., C. subtricolor Lor. and probably also C. nodijlorus (C. Müll.) Jaeg. with C. aureus Bosch &; Lac., C nietneri (C. Müll.) Jaeg. with C. involutusz (C. Müll.) Jaeg., C. subgracilis Ren. &; Card. ex Gangulee and C. latinervis (Mitt.) Jaeg. with C. gracilis (Mitt.) Jaeg., and C. laetus (Mitt.) Jaeg. with C. savannarum (C. Müll.) Mitt. C. pterotoneuron (C. Müll.) Jaeg. is reduced to a variety of C. umbellatus (Arn.) Par. The occurrence of C. exasperatus Brid. on Sri Lanka could not be confirmed. Campylopus flagelliferus (C. Müll.) Jaeg. is reported as new to Sri Lanka.
