The world's oldest herbarium specimen collection, Dalea candida Willd NCSC00010804

BLOG - Two dried plant fragments about 40 cm long provide insight into the importance of documentation systems for science. The specimens taken from a rocky cliff in the Americas were unidentified for more than 300 years.

The world's oldest herbarium specimen collection, Dalea candida Willd NCSC00010804

There is no information about who first, in 1501, took the specimen with ID: 376f695f-67b0-414e-82e7-8934027c80b3 from nature and there was no official taxonomic description of the plant until the 1800s, Carl Ludwig Willdenow, wrote to Species Plantarum ed. 4. 3: 1337 (1802) with the name Dalea candida.

Willdenow who got the standard abbreviation Willd was born in Germany on August 22, 1765, and began his career as a pharmacist, but was fond of collecting herbariums in his teens. He is considered one of the earliest figures in phytogeography who investigated the geographical distribution of plants.

Willd became a member of the Berlin Academy of Sciences in 1794 and was director of the Botanical Garden in Berlin from 1801 until his death in 1812. He studied many South American plants brought by Alexander von Humboldt (1767-1835), related their adaptation to climate and showed that similar climates had species with similar characteristics.

Humboldt (Humb) was also one of the earliest and most famous phytogeographers who influenced Charles Darwin and Ernst Haeckel. He eventually continued and helped expand the garden after Willd's death. The herbarium contains over 20,000 species.

Over time the taxon has been synonymized with several species including Petalostemon candidus Willd. (Michx. in Fl. Bor.-Amer. 2: 49, 1803), Psoralea candida Willd. (Poir. in J.B.A.M.de Lamarck, Encycl. 5: 694, 1804) and Kuhnistera candida Willd. (Kuntze in Revis. Gen. Pl. 1: 192, 1891).

Somehow the specimens passed to Delzie Demaree (1889-1987), an American botanist and plant collector. Demaree collected more than 50,000 specimens and are stored at Southern Methodist University, University of Arkansas, University of North Carolina, National Herbarium of Victoria Royal Botanic Gardens Victoria, National Herbarium of New South Wales, and Australian National Herbarium.

The specimens are stored at North Carolina State University Vascular Plant Herbarium with catalog ID: NCSC00010804 until now. D. candida is a flowering plant in the Fabaceae, has two varieties, namely Dalea candida var. candida and Dalea candida var. oligophylla (Torr.) Shinners.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Chameleon forest dragon (Gonocephalus chamaeleontinus)

Bunglon hutan or chameleon anglehead lizard or chameleon forest dragon ( Gonocephalus chamaeleontinus ) is an animal species in Agamidae, having a larger size than other species, the most unique head shape and has the ability to change color by changing mood rather than for camouflage. Morphology G. chamaeleontinus has a total length of 40 cm, the muzzle to the buttocks is 16 cm, the base color is green with orange, yellow to brownish spots and sexual dimorphism. The eyes are protected by a movable eyelid surrounded by a slightly darker color, while males have a bright blue color around the eyes. Short head with a triangle and thorns above the eyes.

Takenoshin Nakai swallow-wort (Vincetoxicum nakaianum) replaces V. magnificum and C. magnificum

NEWS - Researchers reported an erect herbaceous species distributed in the eastern part of Honshu Island, Vincetoxicum magnificum (Nakai) Kitag. based on Cynanchum magnificum Nakai, nomen nudum. Therefore, they named this species Takenoshin Nakai swallow-wort ( Vincetoxicum nakaianum K.Mochizuki & Ohi-Toma). Vincetoxicum Wolf (Asclepiadeae) is the third largest genus in the Asclepiadoideae consisting of about 260 species geographically extending from tropical Africa, Asia and Oceania to temperate regions of Eurasia. A total of 23 species are known from Japan, including 16 endemic species. Molecular phylogeny divides Japanese Vincetoxicum into four groups: the “Far Eastern” clade consisting of 11 endemic species and 4 more widespread species, 1 sister species to the “Far Eastern” clade, the “subtropical” clade consisting of 2 species and the “Vincetoxicum s. str.” clade consisting of 5 species. V. magnificum (Nakai) Kitag. (Japanese: tachi-gashiwa) is closely related to V. macro...
