fronde ultra 30 cm alta, oblonga, acuminata, 4-5-pinnatifida 
rhachi decidue puberula, castanea, lamina viride diaphana, prae- 
cipue ad costas pilis longis paucis adspersa; segmentis ultimis 
vix 0.5 mm latis, ad apices plerumque retusis; venis spuriis 
nullis; indusio anguste turbinato-cylindrico, exalato, margine 
subbilabiato et paullo dilatato, receptaculo exserto. 
No. 26. Scandent on base of trunks in shady jungle. 
A remarkably beautiful fern; related to Trichomanes speciosum Willd., 
and superficially much like T. aphlebioides Christ, of New Guinea. The 
larger frond sent me wants the upper part; it was probably 60 cm high. 
DRVOPTERIS PALEATA sp. nov. 
D. Hallieri (Christ) C. Chr. affinis et similis, rhachi ubique 
paleis magnis lanceolatis, et indusiis persistentibus pilosis dis- 
tincta; pinnis insigniter ciliatis, sterilibus 30 cm longis, 4 cm 
latis, fertilibus gracilioribus, apicibus venarum interdum in 
sinubus confluentibus. 
Nos. 136, fertile, and 68, sterile, compose the type specimen. 
Related to Dryopteris Hallieri, as already stated, and also to D. crinipes 
(Hooker) O. K., the veins of which regularly anastomose. 
TECTARI A ( PLEOCN EM I A vel ARCYPTERIS) OLIVACEA sp. nov. 
Stipite fere 1 cm crasso, deorsum paleis filiformibus rufo- 
castaneis crinitis densissime vestito, sursum nitido, castaneo; 
fronde magna, rhachibus nitidis ; pinnae infimae desunt ; sequen- 
tibus ca. 60 cm longis, 20 cm latis, brevistipitatis, acuminatis, 
inferioribus stipitatis, basi cordato-truncatis, 1.5 cm latis, ultra 
mediam laminam pinnatisectis, glabris, papyraceis, superne 
castaneo-viri dibus, subtus olivaceis; lobis falcato-oblongis, ob- 
tusis, integris; venis inconspicuis, interdum more Pleocnemiae 
seriem unam areolarum efformantibus, saepius areolas irregu- 
lares paucas margini vel sinu propiores includentibus ; soris 
medialibus, utroque latere costulae 5-7, nudis. 
No. 172. 
This can easily be mistaken for Tectaria leuzeana, from which it differs 
in superficial view in the exceeding fineness of the basal scales and in the 
less cut pinnules; the slightly different venation is correlated with the pre- 
ceding character. The naked sori would make this an Arcypteris, but the 
appearance is rather that of Pleocnemia. 
TECTARIA (DIGRAM MARIA) ELLIPTICA sp. nov. 
Stipite 50 cm alto, sordide nigro-brunneo, deorsum paleis 
paucis lanceolatis adsperso; fronde ultra 50 cm alta, 35-40 cm 
lata, abrupte acuminata, apice pinnatifida, alibi bipinnatifida ; 
pinnis 5-8-paribus, sessilibus vel superioribus adnatis, infimis 
quam sequentibus brevioribus et latioribus, haud deltoideis sed
