Prof. Weiming Zhu ironwood (Xantolis weimingii) described with completely glabrous flower crowns

NEWS - Xantolis weimingii (Sapotaceae, Chrysophylloideae) is described from Yunnan, southwest China and can be easily distinguished from its relatives by the combination of densely covered plants with ferruginous arachnoid-lanate, oblong or obovate leaves and pendulous staminodes at the base. Xantolis Raf. 1838 (Sapotaceae, Chrysophylloideae) is a small genus of trees and shrubs containing about 14 species with a distribution from the eastern Himalayas to the Philippines in tropical Asia. The genus is morphologically characterized by distinct spines, a sharp anther appendage, lanceolate lobes on the calyx and corolla, and aristate staminodes. Molecular data suggest that the genus is sister to the entire subfamily Chrysophylloideae and is a very isolated and poorly understood genus. Specimens was first collected in the Luzhijiang Valley in August 2015, but only sterile or fruiting specimens were collected. In April 2022, a specimen with flowers was finally collected in Wadie, Yuanjiang...

Thomas Sutikna lives with Homo floresiensis

BLOG - On October 28, 2004, a paper was published in Nature describing the dwarf hominin we know today as Homo floresiensis that has shocked the world. The report changed the geographical landscape of early humans that previously stated that the Pleistocene Asia was only represented by two species, Homo erectus and Homo sapiens . The report titled "A new small-bodied hominin from the Late Pleistocene of Flores, Indonesia" written by Peter Brown and Mike J. Morwood from the University of New England with Thomas Sutikna, Raden Pandji Soejono, Jatmiko, E. Wahyu Saptomo and Rokus Awe Due from the National Archaeology Research Institute (ARKENAS), Indonesia, presents more diversity in the genus Homo. “Immediately, my fever vanished. I couldn’t sleep well that night. I couldn’t wait for sunrise. In the early morning we went to the site, and when we arrived in the cave, I didn’t say a thing because both my mind and heart couldn’t handle this incredible moment. I just went down...
