Trillium smallii is a species of flowering plant in the family Melanthiaceae. It is native to Japan and Sakhalin.[1] It is a rhizomatous geophyte that grows primarily in temperate regions.[1]
Trillium smallii is a glabrous, rhizomatous perennial with erect stems 20–40 cm tall.[2] It has three sessile, depressed rhombic-orbicular leaves, 7–17 cm long and about as wide.[2] The flowers are ascending to horizontal at anthesis and become erect in fruit.[2] The sepals are green or purple-brown, while the petals are usually absent or occasionally 1–3 and small, purple-brown.[2] The fruit is a globose berry about 1–1.2 cm in diameter containing many seeds.[2]
Distribution and habitat
Reproductive biology
Trillium smallii was included in a comparative study of four Japanese Trillium species by Masashi Ohara and Shoichi Kawano.[3] The authors found that, despite differences in ploidy level, the species shared broadly similar reproductive traits.[3] In that study, T. smallii had a mean seed weight of 4.47 mg, the highest reported among the four species examined.[3] Mean seed production was reported as 104.3 and 113.0 seeds per plant in two sampling periods, with estimated seed-setting rates of 48.34% and 52.29%, respectively.[3]
