1906; Province of Tayabas, Mount Banajao (922 Whitford) October, 1904. 
Hymenophyllum subdemissum Christ, Bull. Herb. Boiss. 6 (1898) 140, should 
be united wi th this species. 
7. Hymenophyllum Blumeanum Sprengel, Syst. Veg. 4: 131. 
Luzon, Province of Bataan, Mount Mariveles (3232 Merrill) October, 1903, the 
lanceolate form figured by Van den Bosch Hymen. Jav. Tab. 36, 2. H. polyanthos

8. Hymenophyllum paniculiflorum Presl, Hymen. (1843) 32, 55. 
A small plant recognizable by its large sori which are ovoid or globose, 
terminal and occupying all the segments at the summit of the frond. 
Luzon, Province of Benguet, Mount Tonglon, 2,250 m. alt. (Loher) April, 1904. 
Identical with specimens from Java, leg. Giesenhagen and Raciborslci, and with 
specimens from Japan, leg. Faurie. 
I am now of the opinion that H. discosum Christ, Bull. Herb. Boiss. 6 (1898) 
140, should be united with this species, although the sori are much broader and 
more round than those in the Javan plant, leg. Giesenhagen.

100 .

This plant is identical with the form found in New Zealand and Celebes, low, 
with small sori, the rachis winged only near the summit. H. productum Kze. 
Bot. Zeit. (1848) 305, Van den Bosch Hymen. Jav. Tab. 1,5, of Java, is a larger 
plant with triangular elongated valves and winged stipes.
