This paper demonstrates experimentally the feasibility of a novel micro-rotor actuation concept. We demonstrate how a fluid flow, created by the interactions between a bubble and acoustic waves, can be exploited to assemble and power a micro-rotor at a speed as high as 625 rpm. The 65μm microrotor is manufactured in SU-8 using photolithography, all inspired by a biological structure: the winged seed of the maple tree. Variables controlling the rotation speed are investigated, such as the bubble diameter, the acoustic excitation amplitude and frequency, as well as the rotor geometry. The extractible power is estimated to be in the femtowatt range. Finally, steps are outlined to develop this micro-rotor into a MEMS-based motor delivering tunable, rotary power at the microscale.

Common buckwheat (Fagopyrum esculentum) (2n = 2x = 16) and Fagopyrum homotropicum (2n = 2x = 16) were mated in an interspecific cross and amplified fragment length polymorphism (AFLP) linkage maps were constructed by analyzing segregation in the F2 population. Six hundred and sixty-nine bands were identified using 20 AFLP primer combinations, of which 462 (69%) segregated in the F2 population. The map of F. esculentum has eight linkage groups with 223 markers covering a total of 508.3 cM. The map of F. homotropicum has eight linkage groups with 211 markers covering 548.9 cM. There was one to one correspondence of the esculentum and homotropicum linkage groups. Three morphological markers, distylous self-incompatibility, shattering habit, and winged seed, were located on the AFLP map. Distylous self-incompatibility and shattering habit are tightly linked to each other (1.3 cM) and are located near the center of linkage group 1. Winged seed is located on linkage group 4. Key words: common buckwheat, AFLP, linkage analysis, distylous self-incompatibility, shattering habit.

Gladiolus hamzaoglui (Iridaceae) is described and illustrated as a new species from Erzincan province in Eastern Anatolia, Turkey. It resembles G. halophilus by its secund inflorescence, obovoid fruit, and winged seed, and is related to G. anatolicus based on its leaf and flower features. Also it is compared to G. illyricus because of having some leaf, flower features, and winged seed characteristics. Its distribution, habitat and ecology, etymology, conservation status and diagnostic morphological, and taxonomic features with familiar species are discussed in this paper. Additionally, pollen and seed micromorphological characteristics of G. hamzaoglui, G. halophilus, and G. anatolicus are examined and compared using LM and SEM analyses. IUCN conservation status of G. hamzaoglui is suggested as Endangered (EN) category.

Abstract. Boonthasak W, Ngernsaengsaruay C. 2021. The genus Dolichandrone (Fenzl.) Seem. (Bignoniaceae) in Thailand. Biodiversitas 22: 1120-1128. Morphological, anatomical, and palynological studies of the genus Dolichandrone (Bignoniaceae) Thailand were conducted. Three species, D. columnaris Santisuk, D. serrulata (Wall. ex DC.) Seem., and D. spathacea (L. f.) Seem. were investigated. Morphological descriptions, distributions and ecological information are provided. A key to the species based on morphological characters are leaflet margins, length of lower cylindric tube and upper campanulate tube of corolla, width of upper campanulate tube of corolla, winged seed, shape and characters of fruits, width of septum, characters and width of pseudoseptum. D. columnaris occurs in low-lying rice fields and marshlands only in the peninsular region. D. serrulata occurs in mixed deciduous forest and low-lying rice fields in the eastern, central and peninsular regions. D. spathacea occurs in edges of mangrove forest in the central, south-eastern and peninsular regions. A key to the species based on anatomical characters includes leaf type, number of rows of palisade cells, arrangement of axial parenchyma, and height of ray parenchyma. All pollen grains are similar and do not provide characters for identification within the genus Dolichandrone.
