[Dandelion Seeds] | William Henry Fox Talbot | 2004.111 | Work of Art | Heilbrunn Timeline of Art History | The Metropolitan Museum of Art
This experimental proof is a fine example of the capacity of Talbot's "photoglyphic engraving" to produce photographic results that could be printed on a press, using printer's ink-a more permanent process than photographs made with light and chemicals. Like Talbot's earliest photographic examples, the image here was photographically transferred to the copper engraving plate by laying the seeds directly on the photosensitized plate and exposing it to light, without the aid of a camera. Equally reminiscent of Talbot's early experiments, this image is part of Talbot's lifelong effort to apply his various photographic inventions to the field of botany.

荷花和莲花有什么区别吗?还是都指的同一种花? - 知乎

莲:花柄和叶柄都高出水面,花瓣通常为粉红或白色。产莲子和藕(莲藕)。又称「荷花」。各种成语和古文中出现的基本都是它。Nelumbonaceae(莲科)Nelumbo(莲属)Nelumbo nucifera,曾划入睡莲科。睡莲:叶片浮于水面,叶片有一道深裂口。花也常浮于水面,昼开夜合(所以得名「睡莲」),花瓣常有红、紫红、白、黄等色。莫奈画的是睡莲。Nymphaeaceae(睡莲科)Nymphaea(睡莲属)。

我建议口头上用「荷花」指莲,用「睡莲」指睡莲,这样很明确。

Historical collections reveal patterns of diffusion of sweet potato in Oceania obscured by modern plant movements and recombination
The genes of sweet potatoes reveal that there was contact between Australasia & The Americas at least 500 years before Columbus. What is even cooler? You can also show this voyage across the Pacific just by plotting local names of the crop on a map.

Mere Decorating - e-flux Architecture - e-flux
fern-fever, a decorating trend that spread through Victorian England with such enthusiasm that it has been described as a “social mania.” Individuals would wander the countryside, looking for rare specimens and harvesting them for use as decoration. The plants littered stylish houses and their image made its way into ceramics, furniture design, glassware, and metalwork alike. Hundreds of books were written on the subject. Fern-fever generated a robust economy of its own, which reinforced existing gendered and class-based divisions of labor....

In one of these vials, he noted that a fern spore and grass seedling had accidentally taken sprout in the sealed container and were capable of surviving in the enclosed environment. Seeing the potential, Ward developed his eponymous case, the forerunner to the modern terrarium as well as aquarium, and thus, fern-fever was born.

Wardian cases were like miniature glass buildings, often designed with Gothic arches and detailing. Inside, little landscapes and artificial “ruins” were created out of cork, pumice stone, or coke. Something of a small-scale forerunner to the great glass and iron structures of the era, their economy was propelled by the market novelty and trendiness of glass at the time. ...

“Window gardening (or Hortus fenestralis) originated in Europe and entailed either filling a bay window with plants or attaching a projecting glass case to the exterior of a sash window,” writes Sarah Whittingham, author of The Victorian Fern Craze. “It was particularly recommended for the working classes as the vegetation hid bad views or substituted for no view at all.” Placed primarily in the parlor or drawing room, their maintenance was understood as the job of women, part of a broader “Domestic Floriculture.”

Convergent evolution of effector protease recognition by Arabidopsis and barley | bioRxiv
Carter et al. show that AvrPphB induces defense responses in diverse barley cultivars. They show also that barley contains two PBS1 orthologs, that their products are cleaved by AvrPphB, and that the barley AvrPphB response maps to a single locus containing a nucleotide-binding leucine-rich repeat (NLR) gene, which they termed AvrPphB Resistance 1 (Pbr1).
