Alder Tree Branch with Catkins and Cones - Botanical Illustration #160986 (License: Personal Use)

This vintage-style botanical illustration depicts a mature alder branch with multiple reproductive structures: elongated greenish-yellow male catkins, small reddish-purple female inflorescences, and dark brown woody strobili (cones) from prior seasons. Emerging green leaf buds line the slender, olive-brown twigs, capturing the transition from dormancy to spring growth. The precise rendering reflects 19th-century scientific illustration standards, emphasizing diagnostic features for taxonomic use.

Used in botanical field guides, educational resources, and arboretum signage to help users identify alder species by their unique cone-and-catkin morphology; matches search intent for plant ID, dendrology, or historical botany imagery.
