black; lowest secondary pinnules deflexed over the rachis and not adnate, 
the others adnate, crowded, narrowly oblong, obtuse, entire or nearly so, 
bullate, coriaceous, glabrous and brownish-green above, apparently 
glaucous beneath, with occasionally a scale on a costule and very minute 
whitish hairs on the veinlets; veinlets about 10 on a side, simple or 
forked near the costules; sori subcostular, soon confluent and covering 
the whole surface, without indusium or subtending scale. 
Luzon (Mount Banajao, alt. 2,000 m). 
75. Cyathea calocoma (Christ) Copel. ( Alsophila calocoma Christ in Philip. 
Journ. Sci. Bot. 2 (1907) 182). 
Trunk 6 m high; frond 4 m long; stipe densely clothed at the base 
with straw-white scales up to 4 cm long and 6 mm wide, which are brown 
at the tip, with ciliate, acicular, brown palete about 1 cm long, and with 
every intermediate form, white with brown borders; rachis stout, dark-

short-stalked, abruptly acuminate, rachises like the main rachis but with 
a distinct hairy line above; pinnules crowded, sessile or the lower ones 
stalked, long- acuminate, up to 15 cm long, 15 to 25 mm wide, pinnate 
in the lower part, and the lowest secondary pinnules short-stalked, costae 
with a narrow hairy line above, dark beneath and bearing very few fine, 
pale scales; segments 2 to 3 mm wide, falcate, rather obtuse, usually 
entire, glabrous except for a few white squamules and rather long hairs 
on the nether side of the costules, herbaceous, deep-green above, sub- 
glaucous beneath ; veinlets about 12 on a side, forked ; sori medial, 1 mm 
wide, not reaching the apex, indusium none. 
Luzon, Mindoro. 
C. calocoma var. congesta Christ ibidem, has a more densely and finely spiny 
rachis, and more coriaceous and very crowded pinnules and segments.

76. Cyathea caudata (J. Sm.) Copel. in Philip. Journ. Sci. 1 Suppl. (1906) 
144. 
Trank 2 to 3 m high, 4 to 7 cm in diameter ; stipe very short because 
of reduced pinnse coming down almost to the trank, almost black, 
minutely scurfy and bearing harsh, acicular, dark scales, such as extend 
some 30 cm up the upper face of the rachis, densely spiny; rachis spiny 
only near the base, very minutely and sparsely roughened above, brown, 
bearing a deciduous scurf beneath; frond 1.5 m long; middle pinnae 
about 35 cm long, subsessile, abruptly acuminate, rachises like the main 
rachis, but the furfuraceous squamules more persistent; pinnules 7 to 11 
cm long, about 2 cm wide, sessile, acuminate or caudate, cut at the base 
to the costa, elsewhere to a narrow wing, costa dark-hairy above, purplish 
beneath and minutely and deciduously scaly; lowest secondary pinnules 
sessile but not adnate ; segments serrulate and subfalcate at apex, obtuse, 
about 3 mm wide, costules naked above, scaly beneath, lamina coriaceous,
