Pteridophyllum racemosum (Pteridophyllaceae), an evergreen herb endemic to Japan, produces winter buds on the ground surface. Buds consist of three to four bud scales, young leaves, axillary buds, and a young inflorescence. Young leaves and the young inflorescence curve downward in the bud. Young leaves show circinate vernation. Bud scale tissues are composed of an epidermis, cortex, and a vascular bundle. The cortex is characterized by relatively wide intercellular spaces and deposition of starch grains in the cells.
