ODONTOSORIA (PresI) Fee. 
1. O. decipiens Cesati. 
No. Jt84, Goodenoiigh Bay, altitude 1,200 m. 
New Guinea. 
This plant seems to me too near to the widespread O. chinensis; but T liave 
the judjrmeht of Christ (R^s. Exp. Neerland. 8 (1910) 158) to follow in main- 
taining it as distinct. 
2. O. retusa (Cav.) J. Sm. 
No. 170, Ambasij a rather narrow form. 
Malaya to Melanesia. 
DENNSTAEDTIA Bernhardi. 
*1. pennstaedtia sp., perhaps Dicksonia delicata F. Miiller 
No. 2U- 
This is near to but not identical with D. samoemis (Brack.) Moore. 
MICROLEPIA Presl. 
1. M. Speluncae (L.) Moore. 
Nos. 174, 255. 
Neither of these is typical, and tliey are unlike, but they fall within the 
extremes of M. Speluncae as commonly construed. 
TAPEINIDIUM (Presl) Christensen. 
1. T. marginale Copel. spec. nova. 
^ Stipite 50 cm alto, rhachique supra nigris; fronde fere GO cm alta; 
pinnis maximis 25 cm longis, 1 cm latis, herbaceis, serratis dentibus 
tnmcatis; soris ad apices plurium venarum, latis non altis, strictissime 
marginalibus. 
No. 283. 
A very large relative of T. pinruitum, with strictly marginal sori, usually 
about 2 mm wide and hardly 0.5 mm deep, evident when the frond is seen from 
above. The margin of the frond is slightly modified. The rachis and upper 
end of the stipe are square. . ^^ 
2. Tapeinidium sp. 
No. 261. 
This is distinct from any species known to me, but I suspect that it may be 
Davalha longipinnula Cesati, .
