2. Lindsaya brevipes Copel. species nova. 
Species L. concinnae J. Sm. affinis, stipitibus brevibus et frondibus 
deorsum sensim angustatis distinguenda ; stipitibus confertis, ca. 1 cm 
altis; frondibus 20-30 cm altis, 15 mm latis, pinnis deorsum in rudi- 
menta 1-2 mm longa, integra vel flssa haud remota diminutis, media- 
libus ut L.' concinnae, soris inframarginalibus, venis 1-5 insidentibus. 
No. 237, type; No. 266. 
Lindsaya gracilis Bl. has a wide-creeping rhizome with the fronds far apart 
and the pinnae lobed. 
3. Lindsaya microstegia Copel. species nova. 
Rhizomate repente, 1.5 mm crasso; stipitibus inter se ca. 15 mm 
distantibus, frondium bipinnatarum ca. 12 cm altis; fronde normale 
bipinnata, ca, 30 cm alta., 20-25 cm lata; pinnis utroque latere 2 vel 3, 
subsessilibus, 15-18 cm longis, 25 mm latis, acutis; pinnulis utroque 
latere ca. 30, brevistipitatis, basi cuneatis, apice rotundatis, margine 
inferiore integro plerumque recurvo, superiore erenulato ; soris a margine 
remotis, parvis, pinnulae quaeque ca. 10, ad venulas 1-2 insidentibus, 
indusio pallido, vix 0.2 mm longo, 0. 5-1.0 mm lato, mox sporangiis 
occulto. 
No. 2Jf2. . 
This species suggests L. Natunae Baker, but is very distinct in the position 
of the sorus. 
4. Lindsaya Kingii Copel. species nova. 
Bulindsaya, rhizomate repente, 3 mm crasso ; stipitibus proximis, 
25-30 cm altis, brunneis, deorsum ob baseos palearum aspera, tota 
planta aliter glabra; fronde 45-70 cm alta, 25-30 cm lata, bipinnata, 
rhachi quadrangulare sulcata; pinnis utroque latere 10-15, infimis valde 
diminutis, superioribus vix abbreviatis, medialibus usque ad 18 cm 
longis, 15 mm latis, subsessilibus, acuminatis; pinnulis utroque latere 
30-40, brevistipitatis, dimidiatis, ca. 8 mm longis, 3-4 mm latis, superne 
inciso-crenatis ; soro in lobo quoque uno, inframarginale, plerumque ad 
venulas 2 insidente, indusio breve et lato, pallide brunneo. 
No. 2Jfl (type), 280. 
In appearance, L. Francii- Rosenst. in Fedde’s Repert. 9 (1910) 73, must be 
very like this except as to the lower pinnae, but its sori put it into Odontoloma. 
5. Lindsaya trichophylla Copel. species nova. 
Rhizomate erecto; stipitibus confertis, tenuibus, ca. 2 cm altis; 
frondibus (plantae meae) 5-8 cm altis, ca. 1 cm latis, utrinque angus- 
tatis, glabris, rhachi sulcata; pinnis stipitatis, dimidiatis, ad costam 
anguste alatam in segmenta pauca, divaricata, 0.2 mm lata dissectis,
