Curator Finds, Names New Species of Climbing Milkweed

27.09.2002


The climbing milkweed discovered and named by Alexander Krings has tiny, clustered flowers



A new species of climbing milkweed has been named by Alexander Krings, curator of the North Carolina State University Herbarium (also NCSC, its international Index Herbariorum abbreviation). The species - Gonolobus tenuisepalus Krings - was first collected in the tropical rainforests of southern Costa Rica while Krings was a graduate student in the Department of Forestry.

"The flowers are tiny (about 6-8 millimeters in diameter), purplish to dark brownish-red and borne in very dense, umbellate clusters," said Krings. "Although a number of congenerics occur in Costa Rica, its apparently closest relative is known from Mexico. Based on the mildly fetid fragrance, it is likely pollinated by flies."

Climbing milkweeds constitute one of the most species-rich and interesting groups of vines in the world. Highly advanced, members exhibit a startling array of highly modified flowers. Pollen is borne in removable sacs called pollinia - a trait that has evolved in only one other plant family: the orchids.



"New discoveries such as this highlight the continued importance of herbaria - collections of dried, pressed, mounted, and labeled plants," said Krings. All plant species names are governed by an international code of nomenclature. One of the most important requirements of the code is that a physical specimen must be designated for each new species described. This specimen serves as the voucher for the name and is considered the "type" specimen. As each botanical name must be linked to a type, the herbaria of the world maintain literally millions of type-specimens as the basis of all plant names.

Typical of research herbaria, the NC State Herbarium also maintains a collection of type specimens. Founded in 1898, NCSC is maintained by the Department of Botany and serves in a teaching, research, and extension capacity.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Interference as a new method for cooling quantum devices

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
