Crespí, A. L., Fernandes, C. P., Castro, A., Bernardos, S. & Amich, F. 2007: Morpho-environmental characterization of the genus Dianthus (Caryophyllaceae) in the Iberian Peninsula: D. pungens group. — Ann. Bot. Fennici 44: 241–255.

The morphology of several taxa of the Dianthus pungens group (D. gredensis, D. langeanus, D. pungens subsp. brachyanthus and D. pungens subsp. hispanicus) was characterized. In order to correlate the morphological variability with environmental parameters, an altitudinal and bioclimatic approach was applied. The data provided evidence of apparent correlations between the morphological variability within this taxonomic group and the altitudinal-climatic distribution. As the correlations detected here do not allow to establish significant relationships between the environmental variables considered, a complementary analysis (e.g. a geological approach) is needed. An analytical primer is proposed to pursue the morphological characterization of this genus. Two opposite tendencies were obtained: D. gredensis–D. langeanus and D. pungens subsp. hispanicus. Dianthus pungens subsp. brachyanthus is recognized as an intermediate taxon between the two tendencies, at morphological, altitudinal and climatic level. One new subspecific combination is proposed, and some old combinations are applied again in order to establish the taxonomic group Dianthus pungens (D. pungens subsp. brachyanthus (Boiss.)

Janisová, M., Hrivnák, R., Gömöry, D., Ujházy, K., Valachovic, M., Gömöryová, E., Hegedüsová, K. & Skodová, I. 2007: Changes in understorey vegetation after Norway spruce colonization of an abandoned grassland. — Ann. Bot. Fennici 44: 256–266.

We studied the understorey vegetation (including both herbaceous and moss layers) during the Norway spruce (Picea abies) colonization of an abandoned grassland community along a transect established in the direction of spruce dispersal from a linear source (former plantation). We measured a set of climatical, biological, pedological and soil microbiological variables to reveal their effect on the understorey vegetation during the colonization process. Three factors exhibited significant effects — needle and litter accumulation and reduction of light availability. The percentage cover of needles explained 35.8% of the variance in the species data in the RDA and its pure effect (after setting all other significant variables as covariables) exceeded 12%. This factor exhibited the strongest correlation with the first PCA axis representing the colonization progress of spruce. Light conditions (measured as canopy openness by hemispherical canopy photographs or calculated on the basis of tree size and density) explained much lower proportion of the variance (marginal effect about 21.5% and 2.7% pure effect). We discuss the relationship between environmental factors and species abundance (of vascular plants and bryophytes) along the colonization gradient. The results highlight the importance of litter accumulation in controlling the community structure during the successional development of woodland from previous grassland.

Kull, T. & Oja, T. 2007: Low allozyme variation in Carex loliacea (Cyperaceae), a declining woodland sedge. — Ann. Bot. Fennici 44: 267–275.

The genetic diversity within and among 17 populations of Carex loliacea from Estonia, Finland, Sweden, Poland and southcentral Alaska was evaluated by isozyme analysis. An extremely low allozyme variation was found. Fourteen populations were monomorphic at all 18 isozymes. Only three Estonian populations studied showed limited variation of one isozyme, malate dehydrogenase MDH-A, with two allozymes. Almost all allozyme variation was observed as homozygous variants. Of 400 individuals analyzed, only six revealed heterozygous morphs. The high level of inbreeding (F = 0.91) clearly shows that C. loliacea is a predominantly selfing species. The variation of MDH-A showed some geographic distribution. Finnish, Swedish and Alaskan populations form one group, and Polish and Estonian populations form another. The pattern of intraspecific geographic differentiation may reflect the postglacial recolonization routes.

Narbona, E., Arista, M. & Ortiz, P. L. 2007: Seed germination ecology of the perennial Euphorbia boetica, an endemic spurge of the southern Iberian Peninsula. — Ann. Bot. Fennici 44: 276–282.

Patterns of seed germination of the endemic perennial spurge Euphorbia boetica were studied in two populations in southern Spain. We investigated whether its seeds have any type of dormancy, and whether diverse factors such as temperature, darkness, or acid scarification affect germination of the seeds. Freshly matured seeds of E. boetica do not germinate; they need a dry after-ripening period of up to 3 months to reach maximum germination, which indicates that the seeds have a non-deep physiological dormancy. Seeds of this species seem to present a certain tolerance to fire, since many of them survived after exposure to the mildest treatment simulating fire conditions. Finally, darkness and acid scarification had no effect on seed germination. The high germination capacity of E. boetica seeds both in natural conditions and under diverse treatments suggests that germination per se does not represent a crucial phase in the life cycle of this rare species.

Sood, A., Prasanna, R. & Singh, P. K. 2007: Utilization of SDS-PAGE of whole cell proteins for characterization of Azolla species. — Ann. Bot. Fennici 44: 283–286.

SDS-PAGE profiles of whole cell proteins were used to differentiate among 13 Azolla accessions belonging to six species in section Euazolla. Azolla mexicana, A. microphylla, A. rubra, A. filiculoides and A. caroliniana showed highly identical protein profiles except A. caroliniana 3001, in which two distinct bands of molecular weight 81 kDa and 97 kDa were absent. This can be a useful marker for distinguishing this strain among accessions belonging to section Euazolla. The protein profiles of two accessions of A. pinnata, placed in section Rhizosperma consisted of unique bands in the range of 12–17 kDa, which were absent in all species of section Euazolla. The distinct SDS-PAGE profile, especially those of A. caroliniana and A. pinnata, provide useful fingerprints for identification of strains belonging to these species among mixtures.

Surenciski, M. R., Dematteis, M. & Flachsland, E. A. 2007: Chromosome stability in cryopreserved germplasm of Cyrtopodium hatschbachii (Orchidaceae). — Ann. Bot. Fennici 44: 287–292.

Cyrtopodium hatschbachii is a recently-described orchid species distributed in norteastern Argentina. Natural populations of this species require conservation because they have a very restricted size and distribution and are in danger of destruction. Cryopreservation in liquid nitrogen is the most commonly-applied technique for ex situ conservation of plant genetic resources, but genetic stability after cryopreservation is an important consideration. Chromosome number and morphology are primary cytogenetic parameters that must remain stable after cold storage. We analyzed plants of C. hatschbachii cytogenetically in order to determinate their stability level. The plants from cryopreserved encapsulated seeds were stable at chromosome and phenotypic level, but showed more limited condensation of the chromatin during the first stages of their development. The chromosome number and karyotype analysis of C. hatschbachii is presented for the first time.

Kotiranta, H. & Ryvarden, L. 2007: Botryobasidium baicalinum sp. nova (Aphyllophorales, Basidio-mycetes). — Ann. Bot. Fennici 44: 293–297.

Botryobasidium baicalinum Kotir. & Ryvarden is described from Lake Baikal, southern Siberia, Russia. It is characterized by constantly clamped hyphae, long, thin-walled cystidia, ephemeral small basidia, smooth, thick-walled chlamydospores and navicular or subnavicular basidiospores. The new species is fairly similar to B. parvisetosum, which, however, differs in having smaller cystidia, specialized chlamydospore-bearing cells, ornamented chlamydospores and narrower basidiospores. The new species is illustrated and compared with B. parvisetosum.

A new species, Steccherinum tenuispinum Spirin, Zmitr. & V. Malysheva is described. Its closest relative is S. robustius, and it differs in having lighter-coloured spines, smaller spores, and a peculiar ecology. Steccherinum narymicum is reported for the first time after its original description in 1936. New records and some data on morphology, anatomy and ecology of S. murashkinskyi are given and S. bourdotii is reported as new to Russia.

Spirin, W., Zmitrovich, I. & Malysheva, V. 2007: New species in Junghuhnia (Polyporales, Basidiomycota). — Ann. Bot. Fennici 44: 303–308.

Three new Junghuhnia species are described. Junghuhnia autumnale Spirin, Zmitr. & V. Malysheva is pileate or effused-reflexed, with pale-ochraceous to reddish hymenophore; its spores are broadly ellipsoid. Junghuhnia imbricata Spirin has substipitate basidiocarps, ellipsoid spores, and very thick-walled and heavily encrusted cystidia. Junghuhnia micropora Spirin, Zmitr. & V. Malysheva is strictly resupinate, with tiny pores; its spores are cylindrical and smallest among the Junghuhnia species known in temperate Northern hemisphere. All three species grow on large fallen trunks of Populus tremula in old broad-leaved forests. In addition, a new combination, J. aurantilaeta (Corner) Spirin, is proposed; Junghuhnia vitellina Spirin is its taxonomic synonym.

Tyler, T. 2007: Four new species of Hieracium (Asteraceae) from southern Sweden. — Ann. Bot. Fennici 44: 315–319.

Three new species belonging to Hieracium sect. Hieracium, viz. H. argentarium, H. irmae and H. mucrodentatum, are described from the Swedish province of Värmland. In addition, H. acidolepis is described anew to accommodate the taxon hitherto known as H. acidotum (Dahlst.) Dahlst., because the type specimen (from Värmland) for that name has been shown to belong to a different species.
