Description
Castanea seguinii is a small tree or shrub that usually stays under 12 meters tall. The plant has lance-shaped stipules that are 0.7 to 1.5 cm long and fall off when itβs producing fruit. The leaf stems (petioles) are 0.5 to 1.5 cm long. Leaves are 6 to 14 cm long, with the undersides covered in yellowish-brown to gray scales and a few hairs along the veins when young. The leaves are oblong or elliptic-oblong with rounded or sometimes slightly heart-shaped bases, becoming wedge-shaped when young, and pointed tips. The leaf edges are roughly serrated.
For male plants, the flower clusters (inflorescences) are 5 to 12 cm long and look like catkins. Female inflorescences are in a cup-like structure, each holding one to two (sometimes more) flowers. These cupules are 3 to 5 cm wide and covered with short, sparse, spiny bracts that are 6 to 10 mm long. Each cupule produces two or three nuts, each nut being 1.5 to 2.0 cm in diameter.
Itβs known to flower and produce over the summer season, longer than other chestnut varieties.
