a stalk 2 cm long and the two lateral ones with a broad lobe be-

bangana v. A. v. R. Handb. Suppl. 517 (— D. labrusca var. ternata
me. A. v. R., Bull. Dép. Agr. I 1908: 16 t. 1) from Java is only a
similar tripartite form of A. labrusca. — The very minute sori of
the two young leaves mentioned are furnished with small, densely
glanduloso-pubescent indusia; the species must, therefore, defini-
tely be plased in the subgenus Sagenia.
Aspidium decurrens Pr. forma simplicifrons. (no. 44).
I refer this single-leaved Aspidium to A. decurrens Pr., with which
it otherwise well agrees, because COPELAND has met with similar
undivided forms in Luzon (Phil. J. Sei. 2: 412). — Rhizome quite
vertical, 5 cm long; leaves nearly sessile, oblanceolate, 50 cm long,
from a base 1—2 cm broad gradually widened to 6 em about 10
cm below the shortly acuminate apex.
Asplenium dicranurum n. sp. (Fig. 1).
Euasplenium rhizomate repente apice squamis pallide luteo-brun-
neis lanceolatis. vel ovato-lanceolatis paulo dentatis onusto. Stipi-
libus subfasciculatis griseo-viridibus 1—1 ’/ mm crassis, 10—12
cm longis, cum rachi squamis iis rhizomatis similibus sed magis
ovatis sparse et decidue praeditis. Lamina pinnata cum impari
sramineo-viridi, herbacea vel tenuiter membranacea, lineari-lan-
ceolata, 15—40 cm longa, 12 cm lata; rachi viridi, superne late
sulcata sursum alata, sparse paleacea. Pinnis lateralibus ad 12-
jugis, alternis, mediis 3—4 cm inter se distantibus, anguste trape-
zoideo-oblongis vel lanceolato-oblongis, 4—7 cm longis, 1.5 cm la-

curvatim cuneatis, antice rotundato-truncatis, leviter et irregulariter
serratis versus apicem grosse dentatis, apicibus sive caudato-acu-
