^Mindanao, Lanao, Camp Keithley, 800 m. s. n!., Clemens. 112. 
Near A. contaminans Wall., but different in the numerous, dark, stout spines 
and small frond; distinguished from A. lutehrosa Hk., hy the absence of scales 
among the sori. 
CYATHEA Sm. 
'/ Cyathea caudata (J. Sm.) Copeland. (Alsophila caudata J. Sm. in Hooker’s 
Journal of Botany 3 (1841) 419; Species Filicum 9: 52.) Indusium mem- 
branous, disappearing completely. 
Luzon, Cuming 267 ; Province of Benguet, Baguio, Elmer 5867 ; Province 
of Bataan, Mount Mariveles, Whitford 320, Merrill 3195, Elmer 6809, Top- 
ping 366. 
Cuming’s plant was distinguished by Hooker ehieffy by the long-caudate 
tips of the pimndes; in this respect, none of our plants are equally conspicuous, 
though the tendency is evident. It is variable also in the serrateness of the 
segments. I am altogether unable to distinguish the specimens with an indusium 
from those which have lost it. 
\/ Cyathea christii Copeland n. sp. 
Caudice 3-4 m. alto, 7 cm. crasso, apice basibusque stipitmii jjaleis 
duris sordidis l)ninneis setaceis 15 mm. long’is vestitis; stipitibiis indu- 
mento minuto deciduo vestitis, aculeis sparsis 1-2 mm. longis asperatis; 
fronde 1.5-2 m. longa, tripinnatifida ; rliaclii infra glabrescente subas- 
pera, supra fusca brevi-pubescente ; piniiis infimis dimiimtis deflexis, 
medialibus horizontalibns, 50 cm. longis, 12-14 cm. latis, acnminatis; 
pinnulis 7 cm. longis, 15 mm. latis, serrato-candatis, fere ad costam in 
segmentis lineari-oblongis denticnlatis satis remotis ])lernmqne obtnsis 
divisis, venis infra sparsim et minute paleaceis, aliter glabris, tenui- 
coriaceis, supra atro-viridibns, infra pallidis; ventdis fertilibus fnrcatis, 
sterilibns fnrcatis vel simjdicibns ; soris costalibus; indnsiis fragilibiis. 
Mindanao, Davao, Monte Apo, 1,800 m. s. m., Copeland 1141. 
A relative of G. caudata (J. Sm.) Copeh, and of C. spinulosa Wallieh, more 
delicate in form than either, and rather more pubescent. 
In the same locality is another new species distinguished by bearing large, thin 
paleae on the midribs of the pinnules. The mateiial at hand, Be Vore and Hoover 
326, is not sufficient for a good description. 
TRICHOMANES Sm. 
- Trichomanes merrillii Copeland n. sp.

crassis, pilis rigidis atro-rnbis 1-2 mm. longis vestitis; fronde 15-20 cm. 
alta, 5-6 cm. lata, acuta, bipinnata; rhaclii tereta, pilosa; pinnis patenti- 
horizontalilnis, 3-3.5 cm. longis, 7 nim. latis, obtnsis; pinnulis acros- 
copicis majoribus, 9 mm. longis, 5 mm. latis, in segmentis setaceis pro- 
fnnde dissectis, glabris, coriaceis, atro-viridibus; urceolis supra axillas 
segmentorum acroscojncorum pinnarum, deflexis, biangnlatis, limbis

BauawA-N, Puerto Princesa, 500 m. s. m., Merrill 716. 
A plant with quite the aspect of T. javanicuni, but much more dissected.
