E-mail: [email protected] Key words: Bartsia alpina, Castilleja lapponica, Pedicularis lapponica, Pedicularis sceptrum-carolinum, Rhinanthus minor, Scrophularia nodosa, haustorium. Summary. The root structure and the haustorial formation of 5 northern hemiparasites: Bartsia alpina, Castilleja lapponica, Pedicularis lapponica, Pedicularis sceptrum-carolinum, Rhinanthus minor subsp. groenlandicus (Oro- banchaceae) have been studied. The autotroph Scrophularia nodosa (Scrophulariaceae) has been chosen as a control. It is shown that the main preconditions providing the possibility of rapid haustorium development are the long life of the primary outermost tissue of the root – the rhizodermis that covers the entire length of both young and older roots, and constant readiness of this tissue to form special haustorial hairs, and also an unusual structure of exodermis, which in many details is similar to rhizodermis. The formation of haustorial hairs is one of the earliest structural events in haustorium development; the haustorial hairs are long, with a smooth surface. The division and elongation of cells in the outer tissues play a major role in the early stages of endophyte development. The parasitic form of life influence the inner structure of the vascular cylinder that appears as the reduction of phloem conductive elements and the ac- cumulation of large amounts of starch in the xylem.

Features related to peculiarities of the leaf, bracteole, alar pedicel and corolla were found to be important in sep- arating the taxa morphologically, but principal component analysis of all characters showed some anatomical characters (mean number of stomata, diameter of vascular bundle and scleranchymatic sheath) to be more important than morphological ones in explaining the variation between the examined taxa.

Ernst J. van Andel D.W. Janssen and H.J.M. Nelissen Department ofEcology andEcotoxicology, Free University, Amsterdam, and'Department ofPlant Ecology, State University of Groningen, Haren, The Netherlands SUMMARY The reproductive allocation of dry matter and mineral nutrients to flowers, capsules and seed was studiedin plants of Scrophularia nodosa grown in a factorial, three(irradiation) x three(soil fertility), scheme in an experimental garden and in an irradiationgradient (on a natural soil) in a glasshouse. In the irradiationgradient a marked trade-off between sexual reproduction and vegetative propagation was shown: more flowering and seed production at higher irradiation, exclusively rhizome production at the low irradiation. There was no convergence between carbon allocation and nutrient allocation. At decreasing irradiation, biomass production decreasedand concentrations of K, N, Na and P increased inall plant parts. In the factorialexperiment a reduction of the irradiationfrom full daylight to 8% of daylight decreased the biomass production and the shoot:root ratio, once more enhanced by decreasing soil fertility,and increased the leaf area ratio. The specific leaf weight was only affected by the irradiationlevel, except at high soil fertility. The dry weight of the rhizome showed an irradiation and soil fertility interaction. Key-words: Scrophularia nodosa, mineral nutrition. irradiation, reproductive allocation, soil fertility.

  • Pseudorchis Albida (L.) Á
    Pseudorchis albida (L.) Á. and D. Löve Small White Orchid As the common name suggests, Pseudorchis albida is a diminutive orchid with tiny, creamy- white, scented flowers that attract a variety of day-flying insects. It is able to tolerate a wide range of ecological conditions, having a pH range of between 4 and 7, but is most often found in low fertility mesotrophic grasslands and acid heathlands, and more rarely in base- rich mires, limestone heath, and cliff ledges. It is most widespread in the north and west of Scotland but has experienced substantial declines across its range, particularly in Ireland, England and Wales. Pseudorchis albida is assessed as Vulnerable in GB and Critically Endangered in Wales. ©Joan Canals IDENTIFICATION having stomata above (only on the underside of the leaf in P. albida), G. repens by the presence of petioles and C. viride by Pseudorchis albida is a diminutive orchid with a dense spike the absence of longitudinal streaking (Poland & Clements, of very small, creamy-white flowers (2-4 mm across) with a 2009).

General background The Swedish government and Parliament have during the years since Sweden in 1994 ratified the Convention on Biological Diversity (CBD) taken decisions at several occasions regarding biodiversity. The earliest decisions after the ratification are the following: - Bill to Parliament 1993/94:30: A Strategy for Biological Diversity (enclosed) - Bills to Parliament in 1996 (1996/97:75) and 1997 (1997/98:2) on action plans for biodiversity. These two Bills were based on four sectoral action plans produced in 1995 by the National Board of Forestry, the Swedish Board of Agriculture, the National Board of Housing, Building and Planning, and the National Board of Fisheries (enclosed), plus an action plan also from 1995 produced by the Swedish Environmental Protection Agency (SEPA) (attached). The biodiversity strategy and action plans from the 90:ies have been, in several but not all parts, superseded by the system of sixteen environmental quality objectives, adopted by Government and Parliament. These objectives express the environmental quality that should be reached within a generation (ca 25 years from 1999).

Coeloglossum), Gymnadenia (incl. Nigritella) and Pseudorchis were examined by light microscope and SEM. Qualitative and quantitative characters were analyzed. In Dactylorhiza, the seeds are fusiform, but some populations of D. viridis show clavate seeds. According to the ornamentation of the periclinal walls, 3 types of seeds are recognized in this genus. The considerable variation in the seed coat ornamentation pattern in the taxa belonging to majalis, maculata, and praetermissa groups of the genus Dactylorhiza is congruent with the genetic processes that occurred during the history of this genus. Gymnadenia shows clavate seeds with stout and straight to slightly curved anticlinal walls, although these are straight to wavy in some taxa considered previously as Nigritella. These taxa also show low values of seed length. Pseudorchis has fusiform seeds without ornamentation in the periclinal walls and fine anticlinal walls.
