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. A brief history, as well as links to its type catalogue, can be found at: http://www.cals.ncsu.edu/botany/ncsc/history.htm.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
