Common Foxglove

<em>Digitalis purpurea</em> is a biennial or short-lived perennial plant in the family Plantaginaceae, order Lamiales, commonly known as common foxglove. This species is widely cultivated as an ornamental plant and has been naturalized broadly across the globe, with presence documented across Africa, Asia, Europe, North America, Oceania, and South America. <em>Digitalis purpurea</em> typically grows in open woodlands, woodland clearings, hillsides, and disturbed ground, particularly on acidic, well-drained soils. In its first year, the plant forms a rosette of large, softly hairy leaves; in its second year it produces a tall flower spike, often exceeding one meter, bearing distinctive tubular, purple-pink flowers with spotted throats. The flowers are adapted for pollination by bumblebees. The plant contains potent cardiac glycosides, particularly digitoxin and digoxin, compounds that have been critically important in the development of heart failure medications. Despite its medicinal importance, the plant is toxic if ingested. Biological traits of this species remain poorly documented in the scientific literature.

Complex-toothed Flying Squirrel

<em>Trogopterus xanthipes</em>, the complex-toothed flying squirrel, is a medium-sized gliding rodent in the family Pteromyidae endemic to China, where it inhabits montane broadleaf and mixed forests at elevations typically between 1,000 and 2,700 metres in provinces including Sichuan, Yunnan, Guizhou, Hubei, and neighbouring regions. This species is the sole member of the genus Trogopterus and is distinguished by complex tooth morphology compared to other flying squirrels. Like all flying squirrels, it possesses a patagium — a gliding membrane stretching between fore and hind limbs — that enables it to glide between trees rather than undertake powered flight. The complex-toothed flying squirrel is nocturnal and arboreal, spending its days sheltering in tree hollows and foraging at night for leaves, bark, seeds, and fungi. Its faeces, known as Wuflingzhi, have been used in traditional Chinese medicine for centuries, leading to trapping pressure in parts of its range. The IUCN classifies this species as Near Threatened, reflecting population decline driven by overhunting for medicinal use and ongoing habitat loss from logging and agricultural encroachment in montane forests. Biological traits including average body mass, lifespan, litter size, and home range are partially documented but detailed population estimates are limited. Conservation measures include legal protections under Chinese wildlife law.
