Taxonomic notes on European taxa of Crataegus (Rosaceae)

In connection with systematic study of European taxa of Crataegus (Rosaceae subfam. Maloideae) lectotypes are designated for Crataegus monogyna f. subdigyna and C. monogyna var. ronnigeri. C. microphylla subsp. malýana is described as a taxon new to science and a key to the recognised taxa of C. microphylla and of the closely related C. rhipidophylla is given.     

Taxonomic and nomenclatural rearrangement in the Hookeriales with notes on West Indian taxa

The Hookeriales are evaluated to discern familial limits. Five families are recognized in the order: Hookeriaceae, Leucomiaceae, Daltoniaceae, Callicostaceae, and Adelotheciaceae fam. nov. Chaetomitrium Dozy & Molk., Chaetomitriopsis. Fleisch., Dimorphocladon Dix., and Elharveya Crum are transferred to the Hypnaceae. Hookeriopsis (Besch.) Jaeg. is split into four genera: Hookeriopsis s. str., Brymela Crosby & Allen, Thamniopsis (Mitt.) Fleisch., and Trachyxiphium Buck, gen. nov. The following new combinations are proposed to coincide with the recognition of these four genera rather than Hookeriopsis s. lat.: Brymela acuminata, B. callicostelloides, B. cuspidata, B. fissidentoides, B. fluminensis, B. obtusifolia, B. parkeriana, B. rugulosa, B. websteri, Thamniopsis cheiloneura, T. cruegeriana, T. diffusa, T. incurva, T. langsdorffii, T. pappeana, T. purpureophylla, T. secunda, T. sinuata, T. terrestris, T. undata, T. utacamundiana, T. versicolor, Trachyxiphium aduncum, T. guadalupense, T. heteroicum, T. hypnaceum, T. pernutans, T. subfalcatum, T. tenue, T. vagum, and T. variable. Excluded species are treated as Isopterygium plumicaule, Schizomitrium cirrhosum, and S. subsecundum. Schizomitrium belangerianum (Besch.) Buck, comb. nov. is considered distinct from S. depressum (Hedw.) Buck & Steere, and S. pallidum (Hornsch.) Crum & Anders. is shown to have a smooth seta sometimes. The taxonomy of the aquatic species of Cyclodictyon Mitt. and Lepidopilum (Brid.) Brid. is clarified, resulting in the recognition of three species, Cyclodictyon subtortifolium (Bartr.) Buck, comb. nov., C. roridum (Hampe) Kuntze and L. tortifolium Mitt. Two new combinations are proposed in Calyptrochaeta Desv., C. setigera and C. albescens.     

Taxonomic, nomenclatural and chorological notes on several taxa of the genus Echinodorus (Alismataceae)

Taxonomic, nomenclatural and chorological notes on several taxa of the genus Echinodorus are given. A new species E. maculatus is described. The name Alisma intermedium (basionym of the name E. intermedius) is lectotypified. Echinodorus major and E. martii should be treated as two distinct taxa. The name E. xinguensis was invalidly published. It is also confirmed that E. africanus, E. veronikae and E. viridis (all belonging to the E. uruguayensis group) do not originate from Africa. The name E. bleherae should be written with a female suffix (-ae); this name is considered here as a synonym of the earlier name E. grisebachii.     

A comparative study on two closely relative Tulipa L. taxa from NE Anatolia

This study presents observations on the anatomical, palynological and ecological features of Tulipa gumusanica Terzio?lu and its morphologically similar relative, T. armena Boiss. var. armena, in order to clarify their similarities and differences. We found that these taxa have some important differences with regard to anatomical, palynological and ecological features, as well as morphological traits. General anatomical traits of both examined taxa are similar, both having isolateral leaves with distinct hypodermis and a stem with distinct monolayer collenchyma close to the epidermis. However, some anatomical characters such as mesophyll width, average number of stomata on lower epidermis, and epidermal cells on upper epidermis are found to be important in delimiting these taxa. In addition, considerable differences have been observed in pollen shape and size. The species differ ecologically in that T. gumusanica prefers slightly acidic soil with low organic content in the woodland, whereas T. armena var. armena prefers slightly alkali soil with high organic content in steppe vegetation.

Even more new taxa from South and East Anatolia I

A total of 25 items are listed. 16 are new taxa described from South and East Anatolia:Papaver (1),Heldreichia (1),Astragalus (1),Lotus (1),Onobrychis (3),Sempervivum (2),Hellenocarum (1),Cirsium (2),Campanula (1),Omphalodes (1),Allium (1) andPuccinellia (1). Nine other species belonging to the generaDiplotaxis, Beta, Acacia, Lupinus, Cirsium, Limonium, Calamagrostis andPuccinellia, are new records for the Flora of Turkey area. Two combinations are made, one inPapaver (p. 113), the other inHellenocarum (p. 122).     

Taxonomic notes on Calymperes

Abstract

The features that distinguish the hitherto confused species Calymperes moluccense Schwaegr. and C. palisotii Schwaegr. ate outlined and the nomenclature of these taxa is revised. Attention is drawn to the similarity between the Asian species, Calymperes geppii Besch. and C. palisotii subsp. richardii (C. Miill. Hal.) S.R. Edwards, from tropical America.     

Even more new taxa from South and East Anatolia II

10 new Turkish taxa are described:Arenaria eliasiana, A. sivasica, A. monscragus, A. angustifolioides; Campanula lycica; Scutellaria orientalis subsp.tortumensis; Stachys choruhensis, S. tundjeliensis; Calamintha caroli-henricana; Aristolochia rechingeriana, the latter two species named in honour ofKarl Heinz Rechinger;Allium vuralii. Dedicated to Prof. DrKarl Heinz Rechinger on the occasion of his 80th birthday. For part I see Pl. Syst. Evol.154, 111–128.     

Taxonomic notes on Polygonaceae from southern tropical Afkica

As part of taxonomic studies of the family Polygonacrae For the Flora Zambesiaca project, two new species from southrrn tropical Africa are described: Persicaria nogueirae S. Ortiz & Paiva, from Zambia and Angola, and Oxygonum annuum S. Ortiz & Paiva, from Zambia. In addition, two new combinations are proposed: Polygonum glomertum Dammer is transferred to the genus Persicaria as Persicaria glomerata (Dammrr) S. Ortiz & Paiva, and Persicaria attemtata (R. Br.) Soják subsp. africana K.L. Wilson is renamed Persicaria madagascariensis (Meisn.) S. Ortiz & Paiva.     

Taxonomic notes on some freshwater Gastrotricha from West Bengal,India

The present paper is a taxanomic account of seven species of gastrotrichs (Gastrotricha: Chaetonotidae) collected from Calcutta and its adjacent areas (Lower Bengal). All the reported species represent new records from the north-eastern region of this subcontinent and three of them are new records from India.     

Taxonomic notes on Calymperes II

Abstract

Calymperes dozyanum Mitt. is recognized as a misapplied name. It is proposed that the taxon described under this name by Fleischer (1904) should be known by its earliest valid combination, Calymperes boulayi Besch., and that C. dozyanum Mitt. should become a synonym of C. moluccense Schwaegr.

The features that distinguish the hitherto confused species C. boulayi [= C. dozyanum sensu Fleischer] and C. graeffeanum are outlined and the nomenclature revised. Calymperes hispidum Ren. & Cardot and a form of this species superficially resembling C. graeffeanum are described.

Ethnobotanical aspects of some taxa in east Anatolia, Turkey

This paper presents a list of some medicinal plants distributed in the East Anatolia region. The list was prepared during an ethnobotanical survey of the region from 1995 to 2002. East Anatolia has a rich flora due to its variable climate and its many ecological zones. This diversity in flora provides a rich source of medicinal plants that has been long utilized by Anatolian cultures; and hence, accounts for the remarkable accumulation of medicinal folk knowledge for the region. This paper provides information about 71 useful plants grown in the region, 20 of which are reported for the first time. In addition to the scientific names, vernacular names and medicinal uses are given for each plant.     

Notes on two nominal taxa of Ephemerum (Bryophyta: Pottiaceae) described from France by Charles Douin

Abstract

Evidence is presented contradicting claims that tubers occur on the rhizoids of Ceratodon purpureus (Hedw.) Brid. These claims are believed to have arisen through confusion with other plants, particularly Dicranella staphylina Whiteh., Barbula arcuata Griff. and Ditrichum pusillum (Hedw.) Britt. An account is given of the tubers of B. arcuata.
