As with last week's spring orchid, shunran, leaves of the keiran are painted with the teitōsobibyō (釘頭鼠尾描) technique, nailhead (teitō -- 釘頭) and mousetail (sobi -- 鼠尾) brushstroke (byō -- 描). It is a technique in which the brushstroke begins with a strong touch like that of a nailhead and is then trailed away like the tail of a mouse. A significant difference between shunran and keiran is that shunran (spring orchid) has only one blossom per stalk while this week's keiran (autumn orchid) has multiple blossoms per stalk.
Before showing my keiran painting, this sketch is a close-up look a cymbidium, an orchid much like a keiran. If you decide to paint this yourself, don't forget the possible use of the kōrokutensaihō technique. When doing the blossoms, you can first do senbyōhō (line) strokes then fill in the inside, or do the inside first (mokkotsuhō) before drawing lines around the outside.
Here is my demonstration painting of a keiran.
