8. Bolbitis sinuata (C Presl) Hennipman
Bolbitis diversifolia (Blume) Schott
Bolbitis subsimplex (Fée) Ching
Bolbitis hydrophylla (Copel.) Ching
Hybrids:
H. 1. Bolbitis x arguta (Fée) Ching
Hennipman doubts whether this fern warrants a separate treatment as
a hybrid; it may be close to Edanyoa difformis (=B. heteroclita).
H. 2. Bolbitis heteroclita x rhizophylla Hennipman, Leid. Bot. Ser. 2 (1977) 291, Fig. 831o
H. 3. Bolbitis x sinuosa (Fée) Copel., two nothomorphs distinguished:
nm. sinuosa
nm. foxii (Copel.) Hennipman
Bolbitis x foxii Copel.
Dubious species:
Leptochilus stolonifer Christ, Bull. Herb. Boiss. Ii, 6 (1906) 1004.
Luzon: Rizal prov., Angilog (type locality). Possibly synonymous with B. heteroclita
but the venation pattern as given by Christ is deviating. Type not traced (Hennipman,
Fl. Males. Ser ii 1 (1978) 330).
Excluded:
Bolbitis presliana (Fée) Ching
Included in Copeland’s treatment in Fern Fl. Philipp. 2 (1960) 260. This taxon
does not occur in the Philippines nor anywhere in Malesia.
4. Cyrtomium C Presl
1. Cyrtomium cf. caryotideum (Wall.) Presl
Phanerophlebia caryotidea (Wall. ex Hook. & Grev.) Copel.
Philippine record based on a sterile specimen by Mearns from Mt. Sto. Tomas
[Copeland, Fern Fl. Philipp. 2 (1960) 248].
2. Cyrtomium cf. falcatum (L.f.) C Presl
Phanerophlebia falcata (L. f.) Copel.
Philippine record based on a Loher collection from Mt. Data [Copeland, Fern Fl.
Philipp. 2 (1960) 248] at the turn of the 1900s.
Diacalpe Blume =Peranema
5. Didymochlaena Desvaux
1. Didymochlaena truncatula (Sw.) J Sm.
6. Dryopsis Holttum & PJ Edwards
