Woodblock print of stylized plants growing and flowering together. The Saururus is instantly recognizable by the spikes subtended by white-variegated leaves. The hypericum flowers are typical for the genus: yellow with a mass of stamens.

My last Saururaceae (for now):
I love seeing interesting plants represented in art. “[Saururus chinensis and Hypericum patulum]” (1930) is a woodblock print in the shin-hanga style by Asano Takeji of Japan. #Hypericaceae #Saururaceae #botany 🌾🧪🌱

Large yellow flowers of Hypericum. Each flower has a conspicuous pompom of stamens bearing yellow pollen.

Pollen is often yellow (from carotenoids & flavonoids), which may be the ancestral color in Angiosperms. Pigments may be UV-protective but have other functions, too, from pollinator attraction to crypsis. 📷: Hypericum frondosum 'Sunburst' #Hypericaceae #pollen #color #Botany #PlantScience 🌾🧪
