Key to the Bolivian genera of Dryopteridaceae View in CoL
1 Sporangia acrostichoid, uniformly distributed over the surface of the fertile segments; fertile and sterile leaves often dissimilar in size and/or dissection ........................................................................................................................................................................ 2
– Sporangia in discrete, ± round sori that are centered on or along the veins; fertile and sterile leaves usually similar in size and dissection .......................................................................................................................................................................................... 8
2 Sterile blades simple, pedately divided, or if 1-pinnate then <10(–17) cm long .............................................................................. 3
– Sterile blades 1-pinnate or more divided,> 25 cm long .................................................................................................................... 4
3 Veins areolate ......................................................................................................................................................................... Bolbitis View in CoL
– Veins free, ± perpendicular to blade margins, simple or forked, rarely or sporadically anastomosing .................... Elaphoglossum View in CoL
4 Sterile blades 1-pinnate-pinnatifid or more divided ............................................................................. Polybotrya subg. Polybotrya
– Sterile blades 1-pinnate .................................................................................................................................................................... 5
5 Sterile blades with anastomosing veins ............................................................................................................................................ 6
– Sterile blades with free veins or with parallel veins joined by a submarginal connecting vein ....................................................... 7
6 Plants mostly terrestrial; leaf buds present near pinna apices; leaf apices usually pinnatifid and tapering .......................... Bolbitis View in CoL
– Plants usually hemiepiphytic; leaf buds lacking or produced at the pinna bases; leaf apices usually conform or subconfrom ......... .............................................................................................................................................................................................. Mickelia View in CoL
7 Sterile pinnae with parallel veins joined by a submarginal connecting vein; distal pinnae conform; each meristele not surrounded by a dark sclerenchymatous sheath ...................................................................................................................................... Olfersia View in CoL
– Sterile pinnae with free veins not joined on the margins; distal pinnae reduced; each meristele surrounded by a dark sclerenchymatous sheath ................................................................................................................................................... Polybotrya subg. Soromanes
8 Veins anastomosing .......................................................................................................................................................... Cyclodium View in CoL
– Veins free .......................................................................................................................................................................................... 9
9 Midribs of penultimate segments adaxially flat or commonly grooved, or with slightly raised edges .......................................... 10
– Midribs of penultimate segments adaxially raised ......................................................................................................................... 14
10 Blades 1-pinnate; sori indusiate ........................................................................................................................................ Cyclodium View in CoL
– Blades 1-pinnate-pinnatifid or more divided, if 1-pinnate then with exindusiate sori ................................................................... 11
11 Sori exindusiate or (in two species of Polystichum View in CoL ) with peltate indusia ...................................................................................... 12
– Sori with round-reniform indusia ................................................................................................................................................... 13
12 Vein endings not thickened, ending close to the segment margins; blades lacking pellucid-punctate glands in laminar tissue; segment margins spinulose ............................................................................................................................................ Polystichum View in CoL
