Species 2 (2 in the flora).

Although Eubotrys sometimes is included in Leucothoë, morphological and molecular work (K. Waselkov and W. S. Judd 2008; K. A. Kron et al. 1999, 2002) indicated that it is actually a sister lineage to Chamaedaphne, rather than to Leucothoë in the narrow sense. Notably, the pedicel bracts are located close to the pedicel apex in Eubotrys, while the bracts are near the base of the pedicel in Leucothoë. The development of the inflorescences on twigs of the current year in autumn has apparently evolved in parallel within Eubotrys and Leucothoë in the narrow sense.
