Notes on some African hepatic genera 1–5

The present study deals with five genera of hepatics in Africa, Isotachis Mitt., Anastrophyllum (Spruce) Steph., Tritomaria Schiffn. ex Loeske, Gymnocoleopsis (Schust.) Schust. and Lophozia (Dum.) Dum. All African populations of the genus Isotachis Mitt. are considered to be one species, I. aubertii (Schwaegr.) Mitt. Four species of Anastrophyllum (Spruce) Steph. (s.l.), A. auritum (Lehm.) Steph., A. piligerum (Nees) Spruce, A. subcomplicatum (Lehm. et Lindenb.) Steph. and A. minutum (Schreb.) Schust., and two species of Tritomaria Schiffn. et Loeske, T. camerunensis S. Arnell and T. exsecta (Schrad.) Schiffn. ex Loeske occur in Africa. Gymmocoleopsis multiflora (Steph.) Schust. represents a genus and species hitherto unreported for the African flora. Finally, five Lophozia (Dum.) Dum. species, L. argentina (Steph.) Schust., L. capensis S. Arnell, L. decolorans (Limpr.) Steph., L. hedbergii S. Arnell and L. tristaniana (S. Arnell) Váňa, are reported from central and southern Africa; two of these (L. argentina (Steph.) Schust. and L. decolorans (Limpr.) Steph.) represent the first reports from Africa.     

New chromosome counts in nine endemic species from Iran

Original meiotic chromosome counts are presented for nine endemic species in seven families of Angiosperms from Iran including:Arum giganteum Ghahr. (Araceae) (n=14),Caccinia actinobole Bunge (Boraginaceae) (n=8),Delphinium aquilegifolium (Boiss.)Bornm. (Ranunculaceae) (n=8),Diplotaenia damavandica Mozaff., Hedge etLamond (Apiaceae) (n=11),Gypsophila caricifolia Boiss. (Caryophyllaceae) (n=17),Iphiona arachnoidea (Boiss.)Anderb. (Asteraceae) (n=9),Moltkia gypsacea Rech. f. etAellen (Boraginaceae) (n=20),Onobrychis gaubae Bornm. (Fabaceae) (n=8) andOnosma platyphyllum Riedl (Boraginaceae) (n=9). Eight counts are reported for the first time. Furthermore, the previous chromosome count forIphiona aracnoidea is corrected. Based on cytological data the species status ofMoltkia gypsacea is confirmed; it is not merely synonymous withM. coerulea (Willd.)Lehm. The basic chromosome number n=11 is reported in the genusDiplotaenia for the first time.     

LignicolousHyphomycetes from Czechoslovakia 1.Brachysporium

Four species of the genusBrachysporium Sacc. emend.Mason etHughes are treated in this paper from Czechoslovakia:B. nigrum (Link)Hughes,B. obovatum (Berk.)Sacc. and two new species,B. abietinum Hol.-Jech. andB. brevius Hol.-Jech.     

Chromosome counts of some Cuban Angiosperms

Chromosome numbers are reported for 14 species collected in Cuba. The first chromosome records are reported forAlbizzia cubana Britton etWilson (2n=26),Atkinsia cubensis (Britton etWilson)Howard (2n=26),Caesalpinia violacea (Mill.)Standl. (2n=24),Colubrina ferruginosa Brongn. (2n=24). Chromosome numbers of the following species were confirmed:Albizzia lebbeck (L.)Benth. (2n=26),Canavalia maritima (Aubl.)Thouars (2n=22),Casuarina equisetifolia Forst. (2n=18),Cedrela mexicana M.J. Roem. (2n=56),Delonix regia (Bojer)Raf. (2n=28),Guazuma tomentosa H.B.K. (2n=16),Lysiloma bahamense Benth. (2n=26),L. latisiliqua (L.)Benth. (2n=26),Samanea saman (Jacq.)Merrill (2n=26),Thespesia populnea (L.)Soland (2n=26).     

The arthropodBundenbachiellus giganteus from the Lower Devonian Hunsrück Slate, Germany

The large Hunsrück Slate arthropodBundenbachiellus giganteus (Broili, 1929) has been interpreted as a myriapod, a possible arthropleurid, and most recently as a distorted specimen of the arachnomorph arthropodCheloniellon. The Single specimen lacks the head region and is characterised by a narrow trunk bearing a series of biramous appendages with a segmented endopod and filamentous exopod. A reinvestigation demonstrates that it is not referable toCheloniellon but represents a distinct taxon of whichEschenbachiellus wuttkensis Briggs &;Bartels, 2001, also based on a Single Hunsrück Slate specimen, is a junior synonym. Minor features ofStürmer &;Bergström’s (1978) reconstruction ofCheloniellon, which were based on the holotype ofBundenbachiellus giganteus, are revised.     

A revision of the genusOlpitrichum Atk

A revision of the genusOlpitrichum Atk. was undertaken, revealing three species:O. macrosporum (Farlow exSacc.)Sumstine,O. patulum (Sacc etBerl.)Hol.-Jech. andO. tenellum (Berk. etCurt)Hol.-Jech.O. macrosporum andO. tenellum occur on decayed cotton bolls,O. patulum on dead rotten wood and bark. Aspergilliform phialosporous state has been found inO. macrosporum andO. patulum.     

Verbeitung einiger seltenen und subendemischen Arten der griechischen Flora mit taxonomischen und chorologischen Betrachtungen

The taxa very rare in Greece,Gentianella bulgarica (Velen.)J. Holub andPrimula elatior (L.)Hill subsp.intricata (Gren. etGodron)Lüdi Balkan-South Carpathian and mountain subendemic taxon of South and South-Central Europe also the oreophytesGentiana asclepidaea L. andAndrosace villosa L. rare in Greece at high altitudes endemic species of Central Europe and arcto-alpic element both extending South as far as Central Italy and Central Greece as well as the relatively rare species in Greece,Crocus biflorus Mill. which exists in South Europe from Sicily and eastwards and finally four otherIridaceae, i.e.: the South Balkan Asia-Minor subendemic speciesCrocus olivieri Gay andC. pulchellus Herbert, the South Balkan endemic speciesC. veluchensis Herbert and the Mediterranean and mostly East-para-mediterranean subendemic speciesHermodactylus tuberosus (L.)Miller are reported and investigated. However new habitats and records in the Greek area of the investigated species are given, their distribution is discussed, while the existence of the taxa most rare in GreecePrimula elatior (L.)Hill subsp.intricata (Gren. etGodron)Lüdi inHegi,Gentianella bulgarica (Velen.)J. Holub,Gentiana asclepiadea L.,Androsace villosa L. andCrocus biflorus Mill. are presented in the form of a dot map and thus the southernmost limits of their spreading in the Balkan peninsula or in S.E. Europe are elucidated.     

Echinodorus grandiflorus (Cham. etSchlecht.)Mich., its geographical distribution and variability

The taxonomy and geographical distribution ofEchinodorus grandiflorus (Cham. etSchlecht.)Mich. (Alismataceae) are stated. Former authors also included plants from southern Brazil and Argentina in this species, without the typical pellucid points on the blades; these belong to different species or to hybrids. The author further describes the hybrids ofE. grandiflorus with some other species of the same genus and two varieties.     

The genusMicromeles revisited

Micromeles Decaisne emend.Koehne (Rosaceae, Maloideae) is shown to be generically distinct fromSorbus L. emend.Crantz. Problems in the taxonomy of the genus are reviewed. The genus appears to be most closely related toRaphiolepis Lindl. but is readily distinguished by a constant set of characters. Both genera may be derived fromSorbus L. emend.Crantz subg.Aria Pers. Analysis of morphological characters is provided. A survey for flavonoids revealed the presence of vitexin and/or luteolin 7-O-glucoside in some members of the genus in a pattern similar to that found in certain Asian species ofSorbus. There are also brief taxonomic notes on some of the species which were examined.     

New fig insects [Hym.: Chalcidoidea] from India: Three torymids parasitic on agaonids

Two new species of fig wasps (Sycoscapter punctatus Abdurahiman & Joseph andSycobiella amplissima Abdurahiman & Joseph) parasitic onManiella delhiensis Abdurahiman & Joseph fromFicus amplissima Smith, and the female of a known species (Philotrypesis anguliceps Westwood) parasitic onBlastophaga quadraticeps Mayr fromFicus religiosa L. are described.     

Taxonomic status of the belemnite genusBelemnopsis Bayle 1878

The Tethyan genus “Belemnopsis” of authors, notBayle 1878, includes 110–120 Bajocian to Hauterivian belemnite species and subspecies from Europe and the southern hemisphere. Its type species,Belemnites sulcatus Miller 1826 from the Callovian to Oxfordian of England, belongs to the Boreal belemnite genusLagonibelus Gustomesov 1956, since Phillips selected a lectotype for it in 1870. But the subsequent designation of the type species byDouvillé in 1879 is invalid according to Art. 67 (h) ICZN, and consequentlyBelemnopsis Bayle gets a nomen dubium. It is also a homonym ofBelemnopsis Edwards inGray 1849, and has, therefore, to be replaced byPachybelemnopsis Riegraf 1980, a junior subjective synonym, the family Belemnopseidae Naef 1922 by MesohibolitidaeNerodenko 1983, and the suborder BelemnopseinaJeletzky 1965 by PachybelemnopseinaRiegraf inRiegraf et al. 1998.
