Copeland, E. B., Notes on the Steere collection of Philippine 

 ferns. (Phil. Journ. of Sc. C. Bot. II. p. 405—407. December, 1907). 



Critical notes upon a small collection of Philippine ferns made 

 by Dr. Steere and published by Prof. Harrington in 1877. 

 The following new "combinations" appear: Dryopteris Bakeri (Harr.) 

 Copel. {Nephrodium Bakeri Harr.), the species being related to D. 

 canescens; Hemigramma latifolia (Meyen) Copel. (syn. Leptochilus 

 latifolius Meyen, Hemionitis Zollingeri Kurz, Hemionitis gymnopter- 

 oidea Copel., {Hemigramma Zollingeri Christ), the peculiar features 

 of fructification and venation being indicated; and Stenochlaena 

 areolaris (Harr.) Copel. {Lomaria areolaris Harr.), this species being 

 regarded as very distinct from its nearest relative, S. palustris. 

 Several species described as new by Prof. Harrington are referred 

 to species earlier described. Maxon. 



Copeland, E. B., Pteridophyta Halconensia : A list of the ferns 

 and fern-allies collected by Eimer D. Merrill on Mount 

 Halcon, Mindoro. (Phil. Journ. of Sc. C. Bot. IL p. 119—150, pl. 

 1—4. April, 1907). 



Introducing the systematic enumeration of the peteridophyta 

 collected there is given a brief account of the trip, of previous scant 

 exploration in this region, and of the character of the fern flora. 

 Mount Halcon is stated to be "probably the third in height amorig 

 Philippine mountains, being nearly 2700 meters in altitude and, 

 so far as known, surpassed only by Mount Apo and Mount Ma- 

 lin dang, both in Mindanao." 



The following are described by the writer as new: Dennstaedtia 

 Merrillij Diplasium brachysoroides, D. oligosorum, D. Merrilli, D. 

 Woodii, Asplenium {Thamnopteris) colubrinum taeniophyllum , Asple- 

 nium laxivenum, Plagiogyria falcata, Acrosores Merrilli, Prosaptia 

 polymorpha, Polypodium setosum calvum, P. paucisorum, P. cuculla- 

 tum planum, P. subfalcatum semiintegrum , P. halconense, Polypodium 

 {Goniophlebium) integriore, Polypodium {Selliguea) calophlebium , Hy- 

 menophyllum halconense, Alsophila melanorachis, Lygodium Merrilli, 

 and Lycopodium halconense. The relationship of these is discussed , 

 and several of them are figured. Maxon. 



Copeland, E. B., Pteridophytes ofthe Hörn ofNegros. (Leafl. 

 of Phil. Bot. II. p. 387—426. October 30, 1908). 



An enumeration of some 180 species of ferns and fern allies 

 collected upon the Hörn ofNegros, a mountain somewhat more 

 than 1800 meter in height, situated at the extreme southern end of 

 the Island of Negros, Philippine Islands. The climate is said 

 to be exceedingly humid, owing to the heavily laden moist winds
