Key to the Bolivian Species of Lindsaea View in CoL
1 Pinnules with distinct midribs (only basally dimidiate) and sori on both sides ............................................................... L. taeniata View in CoL
- Pinnules entirely or mostly dimidiate (unequal-sided), sori restricted to upper (acroscopic) margins ............................................ 2
2 Primary rachises adaxially and secondary rachises on both sides with pale lateral wings; pinnules obtuse ................ L. divaricata View in CoL
- Rachises unwinged or wings restricted to the adaxial sides of the secondary rachises (costae); pinnules variously shaped .......... 3
3 Pinnules coriaceous, veins hidden ....................................................................................................................................... L. stricta View in CoL
- Pinnules herbaceous to subcoriaceous, veins evident ...................................................................................................................... 4
4 Largest pinnules 3–3½ times longer than wide ................................................................................................................. L. arcuata View in CoL
- Largest pinnules to 2½(–3) times longer than wide ......................................................................................................................... 5
5 Indusial margins usually strongly erose; secondary rachises adaxially with pale lateral ridges .............................. L. portoricensis View in CoL
- Indusial margins entire to minutely erose, rarely strongly erose; secondary rachises lacking pale lateral wings ........................... 6
6 Terminal pinnules gradually reduced, confluent .............................................................................................................................. 7
- Terminal pinnules little reduced, not or only slightly connected to the adjacent segments ............................................................. 8
7 Petioles stramineous to basally castaneous, abaxially rounded; rachises rounded to angular, not winged; indusia usually minutely erose-denticulate, 0.15–0.2 mm wide .......................................................................................................................... L. guianensis View in CoL
- Petioles grayish to reddish brown, quadrangular; rachises abaxially rounded, the secondary rachises (costae) with continuous pale ridges or wings; indusia entire, 0.1–0.15 mm wide .............................................................................................. L. quadrangularis View in CoL
8 Blades bipinnate; pinnules ca. 2–2½ times as long as wide, 11–37 × 6–14 mm; terminal pinnules usually longer than wide; blades usually 2-pinnate, rarely 1-pinnate ..................................................................................................................................... L. lancea View in CoL
- Blades simply-pinnate; pinnules to 3 times as long as wide, to 45 × 20 mm; terminal pinnules about as long as wide; blades 1- pinnate ................................................................................................................................................................................
