Yamamoto Baiitsu (1783–1856) was exceptionally skilled in the distinctive mokkotsu and tarashikomi techniques of painting. Mokkotsu is known as the 'boneless' style, wherein ink or paint is applied with no outlines, or very few, and with washes of ink. Tarashikomi is a technique where a second layer of ink is applied while the first is still wet, creating an effect of pooled colours. It was typically used for petals and leaves, like the large grey-brown leaves here.
