L*arLETS OF Paitippine BOTANY [Vor. II. ART. 
E. Blumeanum J. Sm. (Achrostichum Fée Mém. Il. p. 
62) Cuming 194 is E. petiolatum.  Fée's specimen of this 
number evidently had a much shorter stipe than mine, but 
it ean hardly have differed specifically. 
E. Gumingii Fée is unknown to me; it may be E. decurrens. 
My understanding of E. laurifolium (Thours) Moore is 
based on determinations by Dr. Christ. I cannot distinguish 
some of our specimens from E. angulatum (Bl.) Moore, as 
figured by Blume.

CYATHEA Smith. 
Cyathea heterochlamydea Copel. spec. nova. 
Arbor, caudice 3-5 m., alto, 5 cm. erasso; fronde sessile

parvis scabra; pinnis maximis 30-85 em. longis abrupte 
aeuminatis, rhachidibus eastanis, paleis minutis bullatis aliis 
lanceolatis basibus dilatatis 2.5 mm. longis castaneis sparsis 
vestitis, demum  glabrescentibus, subscabris; pinnulis sese 
vix tangentibus subsessilibus, 7 em. longis, ad basin 15 mm.

brevissime stipitatis, 2-3 mm. latis, subfaleatis, acutis, apices 
versus obscure serrulatis, coriaceis, lamina glabra, supra

The nearest relatives of this species are probably C. Christi 
and C. negrosiana, from which it is distinguished by the 
double pubescence of the secondary rachises and the peculiar 
"indusium."' The scale which subtends and half covers the 
'sorus appears to be homologous with the indusium of other species 
rather than with the paleae on the axes,
