Remarks on some species with descriptions of the new forms 
ADIANTUM ARISTATUM Christ, Bot. GAz. 51:356. 1911.— 
A. monochlamys var. latedeltoidea Christ, Nuov. Giorn. Bot. Ital. 
N.S. 4:88. 1897.—Tai-pei-shan, no. 79. 
Curist has later identified his proposed variety with A. Davidi Franch. 
(see Bull. Soc. Bot. France Mém. 1:62), but it differs from that species just 
as the recently described A. aristatum does. 
ADIANTUM ERYTHROCHLAMYS Diels.—Tai-pei-shan, no. 78. 
Probably this is what Curist has named A. monochlamys typus elongatus 
(Nuov. Giorn. Bot. Ital. N.S. 4:88. 1897). It differs, from the typical A. 
monochlamys Eat. in the completely entire margins of its pinnae and in its 
very large indusia. 
ATHYRIUM MONGOLICUM (Franch.) Diels var. Purdomii, var. 
nov.—Habitu, magnitudine, rachi sursum complanata, alata 
typo similis, differt: rhizomate vix repente, apice squamis atro- 
brunneis nitidis linearibus longe acuminatis dense onusto; pinnis 
basi aequalibus, i.e., lacinia anteriore vix aucta; laciniis approxi- 
matis fere quadratis apice truncatis leviter crenato vel obtuse
