lineatum Blume Enum. (1828) 144. 
Mindanao, Province of Zamboanga, San Ramon (1218 Copeland) April, 1905, 
700 m. alt. 
Glabrous, the frond not reduced at the base. It has the appearance of 
Cyclopeltis semicordata, but the pinnae are less numerous, broader and not 
articulate. 
Malayan region. 
.37. Dryopteris Spenceri (Copeland MSS, Nephrodium) n. sp. 
Khizomate elongato, radicoso, foliis paucis (3) stipite 20 ad 30 cm. 
longo rufostramineo, pennae anserinae crassitie, fronde 50 cm. et ultra 
longa 12 cm. lata, oblonga, pinnata, pinna magna basi saepe petiolata 
12 cm. longa 3.5 cm. lata acuminata grosse lobata terminata, pinnis 
lateralibus sessilibus, oblongis, falcatis, breviter acuminatis, plus minus 
crenato-lobatis (lobis 5 mm. latis) 8 cm. longis, 2 cm. latis basi 
inaequalibus antice truncatis postice semicordato-rotundatis rhachimque 
tegentibus, et versus stipitem in auriculas breves trigonas numerosas 
(usque ad 10 utrinque) abeuntibus. Tota planta pube'brevi griseo 
parce obsita, nervis manifestis prominulis, pinnarum lateralium ca. 
6 utrinque 3 aut 4 areolas inter costam et marginem formantibus, 
nervis pinnae terminalis usque ad 12, saepe furcatis, et 10 areolas cum 
areolis aliquot lateralibus (more Pleocnemiae) formantibus, soris numer- 
osis, 4 usque ad 10 utrinque, costulis approximatis saepe ovatis exindu- 
siatis. Textura herbacea, colore laete virente. 
Mindanao, District of Davao, Todaya ( 1464 Copeland) October, 1904, alt. 800 
m. ; Sibulan River (981 Copeland) April, 1904. A plant from San Ramon, 
Mindanao (Copeland s. n.) April, 1905, from about the same altitude as the 
above is distinguishable by its shorter and more numerous pinnae. 
A very large species of the group of D. Stegnogramme (Gymnogramme aspid- 
ioides Blume FI. Jav. pi. 98.) but very different from that species in having a 
large terminal pinna instead of a pinnatifid apex, and with auricles descending 
along the stipe. 
38. Dryopteris simplicifolia (. 1 . Sm.). Nephrodium, simplicifolium J. Sm. 
in Hook. Journ. Bot. 3 (1841) 411. 
A reduced insular form of the D. glandulosa type. The plant small, the 
terminal pinna only developed, the lateral ones reduced to auricles. 
Leyte (315 Cuming). This is the plant figured by Hooker Sp. Fil. 1 : 19. A 
sterile frond with the above specimen shows that it is a larger plant than 
figured and demonstrates clearly that the species is - more especially a reduction 
of D. Spenceri. Specimens from San Ramon, Mindanao (Copeland) February, 
April, 1905, have the nerves less pronounced, the terminal pinna narrower and 
the pubescence more grayish. 
39. Dryopteris prolifera (Retz.) C. Chr. Ind. Fil. (1905) 286. Memionitis 
prolifera Retz. Obs. 6 : 38. 
Luzon, Province of Cagayan (133 Bolster) July, 1905: Province of Tayabas, 
Lucena (61(f Wliitford) August, 1904: Without locality (168 Cuming). 
Throughout the Malayan region to tropical Africa.
