8. Taxillus ritozanensis (Hayata) Chiu in Taiwania 41(2): 163. 1996. 李棟山桑寄生

Leaves subopposite, coriaceous, ovate to obovate-oblong, 4.5-5 cm long, 2-2.5 cm borad; apex obtuse to rounded, base cuneate; petioles 3 mm long. Flowers in dense pedunculate or sessile fascicles; bracts triangular, 1.6 mm long, 1 mm broad; calyx tube 2 mm long; corolla tube 2 mm long, thinly pubescent outside; anthers 4 mm long; style filiform.

Endemic. Parasitic on Mallotus paniculatus (Lam.) Muell.-Arg.

HSINCHU: Litungshan, Kawakami 8664 (Type, TAIF). CHANGHUA: Pakuashan, Takayanagi s. n. 1932. PINGTUNG: Mutanwan, Kudo & Mori 2539; Suchungchi, Sasaki 8671 (Isotype of Loranthus theifer Hayata, TAIF), Hurukawa 8672, Morimoto 790. TAITUNG: Chuyunshan, Liao et al. 10303.

The anthers of isotype are less than 4 mm long, which is in conflict with the original description. This may cause confusion with T. theifer. However, the population at Litungshan and Chuyunshan are not only larger than T. theifer in leaves, flowers and fruits, but also have ferruginous-tomentose vegetative buds.
