97. Dryopteris Crossii (Bak.) C. Chr. Index 259. 1905. 
Syn. Polypodium Crossii Bak. Ann. of Bot. 5: 455. 1891. 
Type from Ecuador, Sierra de Roritroche, Andes of Loja, leg. Cross, Oct. 
1861 (Kew !). 
A very fine plant very near (too near?) to D. laevigata, which it resembles 
by its purplish-castaneous stipe and rachis, size and texture of lamina, but the 
lamina is more gradually narrowed downwards and the cost are strigosely hairy 
beneath. 
Rhizome? Stipe to the lowest pair of glanduliform pinnz up to 15cm long, 
like rachis purplish-castaneous, glossy and quite glabrous. Lamina Jlanceolate, 
25—35 cm long, 6—7 cm broad at the middle, narrowed towards both ends, coria- 
ceous, brown when dry. Pinnz close, sessile, subopposite or alternate horizontal 
or slightly ascending, the lower 3—4 pairs very small, like tubercles on the stipe 
at distances of 3—4 cm; above them 2—3 pairs of gradually larger auriculiform 
pinne, middle ones the largest. 3—3!/» cm long, about 8 mm broad, acute but 
scarcely acuminate, glabrous above, strigose on the costa beneath, furnished with 
a large, 2—3 mm long aérophore at the base beneath, incised to a wing 1—1'/» mm 
broad. Segments a little oblique, close, obtuse but the margins being revolute 
apparently acute, and triangular of shape, the basal ones equal or a little longer. 
Veins about 6 to a side; sori a little above the middle of the vein, exindusiate, 
small, consisting of a few sporangia only.

Ecuador, in pascuis gelidis Andium Paluguillo, 3300 m, leg. A. MILLE 
nr. 125 (RB!). 
Rhizomate breve, decumbente, apice squamis lanceolatis castaneis hirtis onu- 
sto. Stipitibus longissimis, usque ad 40 cm longis, fasciculatis, brunneo-stramineis 
basi fuscescentibus et sparse squamosis, nitidis, decidue hirtis denique glabris, vix 
ultra 11/2 mm crassis. Lamina lanceolata, utrinque attenuata, raro ad 20cm longa, 
medio 2—5 cm lata, rigide coriacea, pallide viridi. Rachi straminea, pilis albidis 
patentibus decidue hirta. Pinnis 10—20-jugis, inferioribus sensim reductis more 
D. oligocarpicae (typus I), saepe reflexis, medialibus maximis, raro ultra 2 cm longis, 
sessilibus, horizontalibus vel leviter falcatis, apice integro acuto, ciliatis, costis 
utrinque et costulis infra setis antrorsis setulosis, inter venas glabris et eglandulosis, 
infra apicem integrum vel serratum ad alam 2 mm latam pinnatifidis. Laciniis 
5—6-jugis, ovatis, subobtusis, obliquis, marginibus dense ciliatis revolutis, basalibus 
aequalibus vel parum auctis. Venis 2—4-jugis, indivisis. Soris infra medium venu- 
larum sitis, rotundis, exindusiatis; sporangiis glabris.
