NANTOU: Chitou, Hayata s. n.; Chitou, Anonymous s. n. PINGTUNG: Arayurayuwan, Kudo & Mori 1392. TAITUNG: Kiriyama to Tipongoe, Suzuki 11205; Wutoushan, Liu 423; Chihpenshushan, Wang W104. Ying (1975) referred this species to S. propinqua Brand from the Philippines. The latter, however, has very small fruits according to the original description. Further study is needed for the plants in the Philippines. Although the type locality of S. trichoclada is not clearly indicated in the original description, it is the same place as that of S. eriostroma Hayata (see note).

H. P. Nooteboom（见文献引证）将H. Migo应用McClure 13164号花标本建立的Bobua austrosinensis Migo归并于Symplocos sumuntia Buch. -Ham. ex D. Don,但后者的叶卵形或狭倒卵形，边近全缘，干后不呈红褐色等特征与 H. Migo 应用的模式标本显然不同。作者看见了H. Migo应用的模式标本，叶千后呈红褐色，边缘具锯齿；花萼裂片卵形，顶端圆，背面被微柔毛，与萼筒等长等特征与本种相同，应属于本种无疑。
