abot79-6a abot79-6a Flowering rosette of the extremely rare Mauna Kea silversword (Argyroxiphium sandwicense subsp. sandwicense growing with a shrubby or tree-like member of the Hawaiian silversword alliance (Dubautia arborea) at about 2,950 m elevation. In spite of great morphological differences (including unbranched monocarpic rosette shrubs, highly branched polycarpic shrubs, trees, and vines), virtually all 28 species in the three genera constituting the silversword alliance retain the ability to hybridize, and many striking hybrid combinations are produced in nature. copyright: Gerald D.

abot80-10 abot80-10 Transverse section, one locule of vigna vexillata (Fabaceae) anther. The three developing pollen grains are at the microspore stage; each has ektexine ridges overlying a thick inner exine wall (endexine). An additional plug of wall material (Zwischenk copyright: Carlos A. P̬rez-Munoz, BSA

abot80-11 abot80-11 Salt-secreting stem cuttings of Avicennia germinans (left) and Frankenia grandifolia (right) placed in a flask containing 30 mM NaCI under continuous fluorescent light. A. germinans salt deposits are scattered white spots, mainly on the upper (adaxial) leaf surface. Long, hairlike, white salt deposits are obvious on both surfaces of leaves and on the internodes of the stem of F. grandifolia. copyright: Ronald A. Balsamo, BSA

abot80-4 abot80-4 Autofluorescent cell walls of the connective bases of three anthers of a thistle, Cirsium horridulum. The stamen filaments extending down from each connective base are not visible because they lack the autofluorescent component in their cell walls. copyright: Thomas C. Pesacreta, BSA

abot81-1 abot81-1 At left, female (top) and hermaphrodite (bottom) flower of bladder campion (Silene vulgaris); their nectaries differ in production of sugar content. At right, a European skipper (Thymelicus lineola) removes nectar from a female bladder campion flower. Differences in nectar production between the genders of plants may affect pollinator activity and, ultimately, indbreeding. copyright: Claudia L. Jolls, BSA

abot81-10 abot81-10 The Bitterroot Valley of western Montana, showing a typical habitat for the rare species, Arabis fecunda: dry and rocky with erodible, sparsely vegetated slopes. This species has a mixed mating system and exhibits inbreeding depression, attributes of reproductive biology that may complicate efforts to preserve its populations. copyright: Matthew B.
