The position of the callose wall is related to the position of the primexine matrix that forms around the peripheral tetrads during microspore development of the compound unit, the pollinium. We report a combined freeze-fracture and freeze-substituti

In Pterostylis concinna individual pollen grains all possess an outer exine wall, pollinia are mealy, and they fall apart easily. In contrast, Dendrobium spp. have hard pollinia in which only pollen grains on the outer surface have an exine, inner po

Pterostylis plumosa (Neottioideae) is an orchid with monosulcate monad pollen. Tetrads may be isobilateral, decussate, tetrahedral, rhomboid or T-shaped, but all pollen grains have a similar shape. Those belonging to the same tetrads are contiguous f

Thelymitra epipactoides has a highly variable visual display achieved through polychromatic flowers and variable inflorescence size, bearing between 7 and 31 flowers, which attract foraging polylectic bees. Only bees of the genusNomia were observed c

Three distinct secretory events in tapetal cells correspond to key processes of microspore development: microspore release and expansion, exine development, and pollen-coat formation and dispersal. First, at the tetrad stage, the lower part of the ra

The stigmatic surface of the orchid Dendrobium speciosum is a cup containing detached cells suspended in a mainly carbohydrate mucilage. The fine structure of the detached cells and their organelles is indicative of secretory cells. The cells contain

The stigma of Dendrobium speciosum does not correspond to any morphological category previously described. The stigma lies on the lower surface of the column as an oval, bowl-shaped depression containing a wet, jelly-like, viscid material, which comp

Summary The influence of levels of temperature, soil moisture, soil nitrogen status, and of light intensity on the survival of New Zealand strains of ryegrass (Lolium spp.) was examined. It was found that not only was the survival of plants reduced b
