Porella densifolia (Steph.) S.Hatt. var. densifolia, J. Jap. Bot. View in CoL 20: 109. 1944.

Specimens examined:— CHINA. Hubei, Shennongjia Nature Reserve, 29 Aug. 1983, K.C. Chang & E.Z. Bai [K.C.Y. Chang] 34386 (IFP, reported by Chang (1988 as P. densifolia var. robusta )).

Notes:— Porella densifolia var. robusta was originally described based on U. Faurie’s collection from Japan by Stephani (1910) as Madotheca robusta . It is separated from P. densifolia var. densifolia by the obtuse apex of the leaf lobe usually with 3 − 4 teeth, and leaf lobule apex often with 1 − 2 teeth as shown in Hattori (1969). The Hubei plants, previously reported as Porella densifolia var. robusta by Chang (1988), have subacute to acute apex of the leaf lobe strongly 1 − 2-toothed, and obtuse apex of the leaf lobule without any teeth ( Fig. 2 View FIGURE 2 ), which fits well with P. densifolia var. densifolia . Porella densifolia var. densifolia is one of the most common Porella taxa in China, and also known from Japan, Korea and Vietnam ( Pócs 1968; Hattori 1978). With its exclusion in China, Porella densifolia var. robusta is thus far known only from Japan.
