Lindsaya nitida Copel. spec. nova. Plate XXI. 
Syaaphlebium, rhizomate rcpeiite, 1.5 mm crasso, paleis minutis ves- 
tito; stipitibus hand rcmotis, ca. -50 em altis, brunneis, rhachibusque 
quadranguiaribus et profunde sulcatis; fronde visa 15 cm alta, 23 cm 
lata, bipinnata; pinnis 5, terminale ot lateralibus oppositis biparibus, 
acuminatis, sessilibus; pimiulis sessilibus; ca. 12 mm longis, 5 mm latis 
basiscopice (sensu frondis) integris, acroscopice integris vel levissime et 
late incisis, apice rotundatis et soro angusto inframarginale eircumdatis, 
papyraceis, subdiaplianis, glabris supra niteiitibus; venis anastomopan- 
tibus, aroolis longis. 
Penridsen mountain, alt. 000 m, Brools 12. 
Fairly connnon, of constant form." L. Hexmttii lias numerous small pinnies, 
the areolae being, as in other related species, shorter and broader. There is 
usually but one sorus, rarely another small one in a lobe. 
Lindsaya orbiculata (Lam.) Mett. var, odontosorioides var. nova. 
Fronde lanceolata, pinnulis obcimeatis, plus minus profunde incisis, 
lobis ca. 1.5 mm latis, venis 2 in soro su1)apicale confusis. 
Tringos, Brooks 19, 1909. 
This fern is so distinct in appearance that I at first mistook it for an Odon- 
fasoria. However, its afhnity to L, tenera Dry. is unmistakably very close, and 
until the group of L, orbiculata can be studied as a whole, M'ith very ample 
material, it seems better not to try to separate its forms as species. 
Adiantum pulcherrimum Copel. spec. nova. Plate XXII. 
Adiantellum, stipitibus confertis^ atrocastaneis, nitidis, dcorsuni paleis 
bruniieis angustis vostitis; fronde deltoidea, 25 cm alta, tripinnata, rha- 
cbibiis supra velutinis; pinnis utroque latere 2 vel 3, superioribus pinnatis 
inferioribus bipinnatis; pinnulis stipitatis, dimidiatis, apice rotundatis 
vel truncatis dentatis, acroscopice lobatis, ca. 17 nmi longis, 7 mm latis, 
€oriaceis, supra atroviridibus, infra caeruleis; venis liberis, supra sulcatis; 
Roris in apices exsonlptos lobonmi impositis, indusio coriaceo nigro, 
r 
obrenifonne, usque ad 2.2 mm lato.

^ock, Brooks 2. 
Distinguished from its Malayan relatives by the ;j;lauctjus nether svirface and 
large, black indusia. A. affine Willd. lias naked rachises, and A. fulcum Raoul 
segments attenuate at the apex. 
Pteris rangiferina Presl. 
Penrissen mountain, alt. 1,200 m, on dry sheltered rock, Brooks 15.- 
This is a form with but few pinnae, all simple, the fertile recurved and the 
sterile very broad; in essentials, however, it is like specimens from Java. Friini 
the Javan material in hand, it seems probable that THeris Dalhousiae and Pteris 
rangiferina both exist in Java, hut are decidedly distinct. 
Taenitis Brooksii Copel. spec. nova. Plate XXIII. A. 
Stipitibus coiifertis, basibus paleis minutis angustis nigris vestitis, 
alitor glabris, rubidis, 3-4 cm- altis; fronde simplLce, ca. S cm alta, 12
