Allamanda or golden trumpet ( Allamanda cathartica ) is a species of plant in Apocynaceae, evergreen, woody shrub, upright, up to 2 meters high, old stems are brown due to wood formation and young shoots are green. The leaves have pointed tips, rough surfaces, 6-23 cm long and gathered in 3-4 strands. The flowers are yellow and shaped like trumpets, 9 cm long and 5-7.5 cm in diameter. This species grows around rivers or open areas that are exposed to lots of sunlight with sufficient rain and high humidity throughout the year. This plant is unable to grow in saline or too alkaline soil and cannot withstand low temperatures. A. cathartica grows well and produces flowers in full sun intensity without obstruction. This species grows well in sandy soil, rich in organic matter and well aerated. The right climate for growth is a tropical climate. The native habitat is at an elevation of 0-700 meters, rainfall 1000-2800 mm/year. Flowers grow year-round in many habitats, propagating by seed an...

NEWS - Hairy crown loosestrife ( Lysimachia pubiflora Q.L.Gan, Z.Y.Li & H.Xu, sp. nov.) from western Hubei Province, China is similar to Lysimachia jinzhaiensis S. B. Zhou & Kun Liu 2014, but can be distinguished from all other species in Subgenus Lysimachia and Sect. Lysimachia nummularia by its pubescent and woody corolla. Lysimachia L. in Primulaceae (sensu lato) comprises about 180 species distributed mostly in temperate and subtropical regions of the Northern Hemisphere with a few species in Africa, Latin America and Oceania. “Flora of China” records 138 species in China distributed mostly in the southwestern Karst region. About 20 new endemic species have been discovered in China, mainly in the vast mountainous region south of the Huai River highlighting Central China as a hotspot for Lysimachia diversity. In June 2014, during an expedition in Fang County, western Hubei Province, Qi-Liang Gan discovered a specimen of Lysimachia that is new to science. L. pubiflora is ...

NEWS - Sumbawa longhorn ( Nemophora sumbana Kozlov, sp. nov.), Timor longhorn ( Nemophora timorella Kozlov, sp. nov.), shining shade longhorn ( Nemophora umbronitidella Kozlov, sp. nov.), Wegner longhorn ( Nemophora wegneri Kozlov, sp. nov.), long brush longhorn ( Nemophora longipeniculella Kozlov, sp. nov.), and short brush longhorn ( Nemophora brevipeniculella Kozlov, sp. nov.) from the Lesser Sunda Islands in Indonesia. The Lesser Sunda Islands consist of two parallel, linear oceanic island chains, including Bali, Lombok, Sumbawa, Flores, Sumba, Sawu, Timor, Alor, and Tanimbar. The oldest of these islands have been continuously occurring for 10–12 million years. This long period of isolation has allowed significant in situ diversification, making the Lesser Sundas home to many endemic species. This island chain may act as a two-way filter for organisms migrating between the world's two great biogeographic regions, Asia and Australia-Papua. The recognition of a striking cli...

NEWS - Three-spot grass-veneer ( Glaucocharis triochellaris Matsui, Yagi & Hirowatari sp. nov.) and dull gray grass-veneer ( Glaucocharis plumbofascialis Matsui, Yagi & Hirowatari sp. nov.) from the Ogasawara Islands of Japan with adult, male and female genitalia and molecular phylogenetic analysis revealed a sister relationship between the two new species and the monophyly of Glaucocharis Meyrick 1938. G. triocellaris is easily distinguished from the other species by distinctive morphological features, such as three black spots on the margin, each enclosing a silvery white spot in the middle of the forewing; a valve with a strong hook-shaped protrusion emerging from the middle of the ventral valve margin and a phallus with hook-shaped apical spines curved ventrally on the male genitalia; and a circular spinous antevaginal lamella on the female genitalia. Although larvae were not found, adults emerged from various Bryopsida species collected on Hahajima Island. The larvae ma...
