354 COPELAND. 
Cyathea (Alsophila) atropurpurea Copel. spec. nova. 
Caudice 2 m alto, 4 cm crasso; fronde loO cm alta, 60 cm lata; pinnis 
infimis remotis, diminutis; stipite breve usque ad basin pinnis paucis 
perrcductis, lamina fere carentibus, praedito; rhaclii atropurpurea, inerme, 
supra in sulca pubescente, aliter glabrescente ; pinnis medialibus maximis 
30 cm longis, 13 cm latis, acutis, breviter stipitatis, rhaciii supra sparse 
pilosa, infra squamiilis sparsioribus praedita; pinnulis 7 cm iongis, 15 
cm latis, caudatis, brevi-stipitatis, prof unde pinnatifidis, et ad basin majo- 
rum pinnatis nee non pinnis" brevissime pedicellatis, costis supra pubcs- 
centibus infra costulisque squamulis bullatis vestitis; segmentis oblongis, 
obtusis, sat grosse serratis; lamina sicca papyracea, purpureo-viride, 
glabra; venulis simplicibus, utroque latere ca. 5; soris fere costalibus, 
receptaculo grande, indusio nullo. 
Mount Ilalcon, Mindoro, alt. 750-1,050 m, Merrill 6056. This plant differs 
from A. ramispina in being tripinnate at the base of the pinnules, with secondary 
pinnules contracted at the base, and the segments everywhere conspicuously 
toothed. The reduced pinnae at the base of the stipe, so evidently pinni-e that 
Hooker could hardly have failed to mention their nature, are not stout enough 
well to be called spines. A. glabra is without the buUate scales and has the 
lower sori remote from the costa. A. duUa is a form with the pinnules very 
shallowly cut. 
Cyathea mitrata Copel. spec. nova. 
Arbor caudice stipiteque ignotis; rhacliide 6 mm crassa^ brunneaj 
minute nodulosa, sparsissime furfuraceo-squamulosa^ glabrescente, apud 
baseos pinnarum et alibi aerophoris cicatricoideis oblongis praedita ; pinna 
fere 40 cm longa, 15 cm lata, sessile, rachi supra pilis ct paleis paucis 
obscuris vestita, infra paleis sparsissimis lanccolatis 2 mm longis et aliis 
minutis sparsis furfuraceis praedita, ad basin incrassata et supra ap- 
planata; pinnulis ^ 7 cm longis^ 15 mm latis, sensim acuminatis, sessilibus, 
pinnatiSj costis supra pilosis infra paleis parvis irregularibus subbullatis 
et rarius aliis 3 mm longis lanceolatis vestitis ; pinnulis " lineari-oblongis^ 
obtusis, inferioribus multis pedicellatis, crenatis, vel inferioribus profunda 
lobatis, margine deflesa, lamina coriacea glabra supra nigra infra brunneo- 
viride; venulis fere occultis apud costulas furcatis; soris costalibus, 1.5 
mm latis, laminam totam obtegentibus, indusio ilrmo globoso mox in 
partes duas fisso, persistente et perconspicuo. 
Mount Malindang, Mindanao, alt. 2,800 m. For. Bur. ffGSl Mearns & Butch' 
inson. 
A species so remarkable for its black quadripinnatifid fronds and very large 
mitriform indusium, persisting long after the loss of the sporangia, that I think 
it may safely be described from a single pinna. 
Cyathea (Alsophila) Fenicis Copel. spec. nova. 
Pilix arborea gregis C. (Alsophilac) contaminantis (AVall.), paleis 
paucis brunneis ad basin stipitis, segmentis latis, et soris strictissime 
costularibus distincta.
