The bipinnate-compound leaf of Parkia clappertoniana has prominent, long petiole with a pulvinal base. The pulvinus has wood, periderm, lenticels and extensive cortical layer. Its vascular bundles are elongated with alternating rays. The vascular bundles of the petiole, rachis and veins are oval, with conspicuous bundle caps. Stomatal complex is predominantly paracytic with occasional occurrence of anomocytic stomata near the midrib. The oval stomata have conspicuous stomatal ledges. Trichomes are unicellular, acicular and restricted to the rachis, petiole and pinnule mid-ribs and margin. Ecological and taxonomic significance of features is discussed.

Fossil legumes of Albizia miokalkora Hu et Chaney (Mimosoideae) were found in the Miocene Duho Formation of the Yeonil Group distributed along the coast of Yeonil Bay in the Pohang area. The legume is flat and long and has 5-7 rounded seeds. The legumes of Albizia miokalkora are rare in the Cenozoic floras of the world and only known to Middle Miocene of East Asia. The fossil Albizia may use one of the important taxa to construct the biogeographic history of East Asia. This discovery is the first record of Albizia from the Neogene strata of Korea.

A cross-linked leucaena (Leucaena leucocephala) seed gum (CLLSG) matrix was prepared for the isolation of galactose-specific lectins by affinity chromatography. The matrix was evaluated for affinity with a known galactose-specific lectin from the seeds of snake gourd (Trichosanthes anguina). The matrix preparation was simple and inexpensive when compared to commercial galactose-specific matrices (i.e. about 1.5 US$/100 ml of matrix). The current method is also useful for the demonstration of the affinity chromatography technique in laboratories. Since leucaena seeds are abundant and inexpensive, and the matrix preparation is easy, CLLSG appears to be a promising tool for the separation of galactose-specific lectins.

아프리카 나이제르산 13관 21종 식물체의 부위별로 채집된 31 시료 메탄올 추출물의 벼멸구에 대한 살충활성 및 점박이이응애에 대한 살비활성을를 가각 미량국소처리법과 잎침지법으로 조사한 결고, 시료의 부위 및 종에 따라 살충 및 살비활성에 커다란 차이를 보였다. Caesalpinacras과의 Cassia occidentalis와 Cassia tora 전부위 및 Mimosaceas 과의 Prosopis chinensts줄기의 메탄올 추출물은 벼멸구에 대해서 강한 살충활성을 보인 반면, 비름과의 Celosia trigyna 전부위, Combretaceae과의 Combretum glutinotum 잎과 Combretum micronthum 전부위 및 Prosopis chinensis 잎과 열매의 메탄올 추출물은 점박이응애에 대해 강한 살비활성을 나타내었다.

The Acacia seyal Del. var. seyal belongs to family Mimosaceae is known locally as gum Talha tree. It is a multipurpose tree species occurs throughout the African gum belt in Savannah mostly in pure forest. In Sudan it thrives on heavy clay soils that receive an annual rainfall between 400-800 mm. It is an important source of rural energy (fuelwood and charcoal) and forage. As mentioned by Nair (2007) the economic damage causes by insect in natural forest often difficult to judge due to no enough research attention The tree is frequently affected by biotic factors among them the insect pests. During a survey in the 1980's the tree was severely infested by the longhorned beetles (Cerambycidae) severely infesting other Acacia species, but the ecological data are overlooked. Therefore, the objective of the study was to assess infestation characteristics and to determine environmental factors triggering the attack of longhorned beetles. A temporary random sampling technique was applied to observe the damage characteristics of the longhorned beetles on tree species during May-July 2007. Five sample plots occupies by A. seyal were taken in Kordofan region directly observed for the presence of hole of emergence of the longhorned beetles, presence of dusts, presence of insect stages, girdling as well as other characteristics of damage. The study results indicate that the infestation rate of trees in the sampled sites ranged between zero and 23.08%. Further ecological researches are recommended.
