Rafinesque’s “absurd” botanical legacy, Gray wrote, amounted to little more than a “curious mass of nonsense.” Gray’s note wouldn’t be the last unkind obituary in the annals of taxonomy, nor would it be the worst. That’s because the rules dictating how taxonomists name and classify living things bind these scientists in a web of influence stretching far back into the 18th century. When an agent of chaos like Rafinesque enters the scene, that web can get sticky fast. In a field haunted by ghosts, someone has to reckon with the dead.
The mysterious and useful Vegetable Lamb of Tartary: a plant whose ripe seed-pods yield tiny live lambs. Or was it a plant growing in the shape of a full-size lamb, but with an umbilical tether to the ground? (Oh, and do you know about the barnacle goose?) A tale from the medieval science grapevine.

In 1928, a farmer digging in his garden found a flower blooming underground. Three years ago, scientists discovered that it's so well adapted to living underground that it has lost almost all of its chloroplast genes. While this species is unusual for an orchid in the extent of its parasitism, it turns out that all orchids are actually parasites--stealing nitrogen from tiny fungi in the soil without trading any carbon back as plants usually do. See photos of the underground orchid here.
"My subject is a barren one – the world of nature, or in other words life; and that subject in its least elevated department, and employing either rustic terms or foreign, nay barbarian words that actually have to be introduced with an apology. Moreover, the path is not a beaten highway of authorship, nor one in which the mind is eager to range: there is not one of us who has made the same venture, nor yet one Roman who has tackled single-handed all departments of the subject."Naturalis Historia was written by Pliny the Elder between 77 and 79 CE and was meant to serve as a kind of proto-encyclopedia discussing all of the ancient knowledge available to him, covered in enough depth and breadth to make it by a reasonable margin the largest work to survive to the modern day from the Roman era. The work includes discussions on astronomy, meteorology, geography, mineralogy, zoology and botany organized along Aristotelian divisions of nature but also includes essays on human inventions and institutions. It is dedicated to the Emperor Titus in its epistle to the Emperor Vespasian, a close friend of Pliny who relied on his extensive knowledge, and its unusually careful citations of sources as well as its index makes it a precursor to modern scholarly works. It was Pliny's last work, as well as sadly his sole surviving one, and was published not long before his death attempting to save a friend from the eruption of Mt. Vesuvius that destroyed Pompeii and Herculaneum, famously recounted by Pliny's eponymous nephew Pliny the Younger.

Search for wildflowers by location, color, flower shape, flower size and time of blooming. 3,126 plants indexed. This web site helps those of us with limited knowledge of botany to identify flowering plants that are found outside of gardens. This help is provided by presenting you with small images of plants. You can use a number of search techniques to get to the images that are most likely the plant you are looking for. When you click on a plant image the program shows you links to plant descriptions and more plant images. The site has about 5 ways of searching for a plant. You can use these searches in any combination. Some searches eliminate some plants from consideration. Most searches give a "score" to each plant depending on how well the plant matches the search criteria. The plants with the highest score are displayed at the top of the results.

Mosses Make Two Different Plants From the Same Genome, and a Single Gene Can Make the Difference
One of the most astonishing secrets in biology is this: every plant you see makes two different plants from the same genome. And, scientists recently reported, a single gene from an ancient, powerful lineage can make the difference.

Leafsnap is a free field guide for iPhone (Android coming soon) that uses the phone's camera and some biometric processing to identify trees by the shape of their leaves. Development was financed by the National Science Foundation (NYT article), and includes research by Columbia University, University of Maryland, and the Smithsonian Institution.

The geranium: Nature's camera. The sensitivity of certain silver salts to light was known from about 1727, when Johann Heinrich Schulze published his findings in the Nuremburg Academy of Natural Philosophers. But many natural things are sensitive to light. Long ago people noticed the effect of light on green plants, or how it made coloured fabrics fade. It is the effect of light on plants that makes Roman Photography possible. [via bifurcated rivets]
