Rabbit Tobacco is a widespread member of Asteraceae (the composite family) which grows in various dry soils. When abraded, squeezed, or otherwise harassed, the plant has a pleasant scent which is interpreted differently by each individual. Native people used various parts of the plants for medicinal and spiritual purposes

#DidYouKnow? In the area of the Franklin and Sterling Hill mines in Sussex County, #NewJersey, 357 types of minerals are known to occur. These 357 types account for approximately 10% of the minerals known to science. Thirty-five of these minerals have not been found anywhere else. Ninety-one of the #minerals #fluoresce. See a display of some of these minerals at the @sterlinghillminingmuseum. #nj #njhistory #SpreadTheHistory #historygirl #history #americanhistory #blog #blogger #travelblog #travelblogger #jerseycollective #explorenj #journeythroughjersey #ogdensburg #ogdensburgnj #sussexcounty #sussexcountynj #skylands #njspots #visitnj #minimgmuseum #sterlinghillminingmuseum #mine (at Sterling Hill Mining Museum) https://www.instagram.com/p/Bwf5ccCHDub/?utm_source=ig_tumblr_share&igshid=1683r4t3b86un

Tree frog found to fluoresce

A moment of serendipity in scientific research led to the discovery of the first known fluorescent amphibian that (in the manner of certain nightclub fashions) glows when exposed to UV light. Pigments in the skin absorb the UV wavelengths; electrons jump to a higher energy state and then give the energy off as visible light as the system returns to equilibrium. What surprised researchers was to find the phenomenon in a well known species of Argentinean tree frog (colloquially called polka dot for obvious reasons, aka Hypsiboas punctatus) while researching their skin pigments at the Buenos Aires Natural Sciences Museum.

The frog was found to emit fluorescent substances from lymph and other glands, increasing its overall brightness by 20=30% depending on the ambient light level. Unlike us some creatures can see in UV wavelengths, though mostly it consists of insects seeing the UV component of flower pigments. The purpose of the glow is unknown at present, and the assumption that these frogs can see in these wavelengths has yet to be tested.

Land animals that glow in this manner are very uncommon, the main other ones being some species of parrot or marine turtle and occasional scorpions, and the compound used was previously unknown in animals, though some plants synthesise similar substances. No one knows how many other frogs around the world glow in this manner, but the team are putting together a research programme to find out with some 250 other species. Future herpetologists hunting their study specimens at night may find it useful in the future to carry a UV torch with them into the field.

Yucca filamentosa, photographed in UVIVF on the left and traditionally on the right. The glowing anther lend a nice alien aesthetic to these lovely flowers.

I’ve grown this Oncidium for 2 years since I bought them coming into a small bloom of 6 flowers. My first rebloom after that time has two extensive sprays of flowers which smell amazing like a blend of jasmine, chocolate, and vanilla. I have no ID for this plant, since it is an unnamed complex hybrid, but it exhibits marked similarity to Oncidium ‘heaven scent.’ The anther caps on these glow with an intensity unmatched by the rest of the plant, and the sepal and petal tips which match the lip in visible light fail to fluoresce to the same degree in UVIVF.
