COPELAND. 
Lindsaya nitida Copel. spec. nova. Plate XXI. 
Synaphlebium, rhizomate repente, 1.5 mm crasso, paleis mimitis ves- 
tito ; stipitibus hand remotis, ca. 30 cm altis, brunneis, rhachibusque 
quadrangularibus et prof unde sulcatis ; f ronde visa 15 cm alta, 23 cm 
lata, bipinnata; pinnis 5, terminate et lateralibus oppositis biparibus, 
acuminatis, sessilibus ; pinnulis 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 circumdatis, 
papyraceis, subdiaphanis, glabris supra nitentibus; venis anastomosan- 
tibus, areolis longis. 
Penrissen mountain, alt. 900 m, Brooks 12. 
“Fairly common, of constant form.” L. Eewittli has numerous small pinules, 
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 obeunSatis, plus minus profunde incisis, 
lobis ca. 1.5 mm latis, venis 2 in soro subapicale confusis. 
Tringos, Brooks 19, 1909. 
This fern is so distinct in appearance that I at first mistook it for an Odon- 
tosoria. However, its affinity to L. te'nera Dry. is unmistakably very close, and 
until the group of L. orbiculata can be studied as a whole, with 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, deorsum paleis 
brunneis angustis vestitis; f ronde deltoidea, 25 cm alta, tripinnata, rha- 
chibus supra velutinis; pinnis utroque latere 2 vel 3, superioribus pinnatis 
inferioribus bipinnatis; pinnulis stipitatis, dimidiatis, apice rotundatis 
vel truncatis dentatis, acroscopice lobatis, ca. 17 mm longis, 7 mm latis, 
coriaceis, supra atroviridibus, infra caeruleis; venis. lib eris, supra sulcatis ; 
soris in apices exsculptos loborum impositis, indusio coriaceo nigro, 
obreniforme, usque ad 2.2 mm lato. 
Penrissen mountain, alt. 1,150 m, on dry sandstone ledge under overhanging 
rock, Brooks 2. 
Distinguished from its Malayan relatives by the glaucous nether surface and 
large, black indusia. A. affine Willd. has naked rachises, and A. fulvuni 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. From 
the Javan material in hand, it seems probable that Pteris Dalliousiae and Pteris 
rangiferina both exist in Java, but are decidedly distinct. 
Taenitis Brooksii Copel. spec. nova. Plate XXIII. A. 
Stipitibus confertis, basibus paleis minutis angustis nigris vestitis, 
aliter glabris, rubidis, 3-4 cm altis; fronde simplice, ca. 8 cm alta, 12
