Since more than two decades, the taxonomy of Hopea has been a point for discussion. Time to time, various taxonomists have tried to classify the species of Hopea on the basis of morphological and anatomical characters. This type of controversy can be solved by the study of various disciplines. Among them, the Scanning Electron Microscopic (SEM) study may be taxonomically useful to resolve the controversies over the classification of the genus Hopea. The SEM study was carried out in Hopea of Sri Lanka. The result of SEM indicates that the two taxa (Hopea jucunda ssp. jucunda and H. jucunda ssp. modesta) possess different epicuticular appearance justifying to upgrade the subspecies of H. jucunda to species level. Key words: epicuticular wax; SEM; stomata; trichome.DOI: 10.3126/botor.v6i0.2919 Botanica Orientalis - Journal of Plant Science (2009) 6: 106-108

AbstractOne new and one known species of Aulolaimus are described, viz. A. multipapillatus sp. n. from Israel and A. nannocephalus from Ukraine. Aulolaimus multipapillatus sp. n. is particularly characterised by a cuticle bearing ca 60 distinct longitudinal ridges, cuticle with distinct ornamentation on ventral body side anterior and posterior to vulva, 6-11 midventral sensilla anterior to cloaca, and spicules ca 25 μm long. Aulolaimus nannocephalus is redescribed on the base of both light and scanning electron microscopic observations on two populations from Ukraine. An emended diagnosis and a revised classification of the genus are proposed. The morphological variability and systematic position of Aulolaimus are discussed and a key to the species of the genus is provided.

Although scanning electron microscopy has a great potential in biological application, there are certain limitations in visualization of the biological structure. Satisfactory techniques to demonstrate natural surfaces of the tissue and the cell have been reported by several investigators. However, it is commonly found that the surface cell membrane is covered with a minute amount of mucin, secretory substance or tissue fluid as physiological, pathological or artefactual condition. These substances give a false surface appearance, especially when the tissue is fixed with strong fixatives. It seems important to remove these coating substances from the surface of the cell for demonstration of the true structure.

The authors have investigated the dissolution process of human cholesterol gallstones using a scanning electron microscope(SEM). This study was carried out by comparing control gallstones incubated in beagle bile with gallstones obtained from patients who were treated with chenodeoxycholic acid(CDCA).The cholesterol gallstones for this study were obtained from 14 patients. Three control patients were treated without CDCA and eleven patients were treated with CDCA 300-600 mg/day for periods ranging from four to twenty five months. It was confirmed through chemical analysis that these gallstones contained more than 80% cholesterol in both the outer surface and the core.The specimen were obtained from the outer surface and the core of the gallstones. Each specimen was attached to alminum sheet and coated with carbon to 100Å thickness. The SEM observation was made by Hitachi S-550 with 20 kV acceleration voltage and with 60-20, 000X magnification.
