- Physocarpus capitatus (Pursh) Kuntze (plants.sc.egov.usda.gov)
Pacific ninebark is a long-lived perennial shrub of the Rose family native to the Pacific Northwest. It grows rapidly with multiple stems achieving 2 to 4 meters in an erect to arching form with angled branches. The reddish papery bark peels off in long thin layers giving rise to the common name. Deciduous leaves that appear alternately along the stem are 3-10 cm long, 3-5 lobed and doubly toothed at the margin. They are deeply veined, shiny dark green above and lighter beneath with fine star-shaped hairs
- Tonian (Wikipedia)
The Tonian (from Ancient Greek: τόνος, romanized: tónos, meaning “stretch”) is the first geologic period of the Neoproterozoic Era. It lasted from 1000 to 720 Mya (million years ago). Instead of being based on stratigraphy, these dates are defined by the ICS based on radiometric chronometry. The Tonian is preceded by the Stenian Period of the Mesoproterozoic Era and followed by the Cryogenian.
