97. Dryopteris Crossii (Bak.) C. Chr. Index 259. 1905. 



Syn. Polypoclium Crossii Bak. Ann. of Bol. 5: 455. 1891. 



Type from Ecuador, Sierra de Roritroche, Andes of Loja, leg. Cross, Ocl. 

 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 costæ are strigosely hairy 

 beneath. 



Rhizome? Stipe to the lowest pair of glanduliform pinnæ up to 15cm long, 

 like rachis purplish-castaneous, glossy and quite glabrous. Lamina lanceolate, 

 25 — 35 cm long, 6—7 cm broad at the middle, narrowed towards both ends, coria- 

 ceous, brown when dry. Pinnæ 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 

 pinnæ, middle ones the largest, 3 — 3'/2 cm long, about 8 mm broad, acute but 

 scarcely acuminate, glabrous above, slrigose on the costa beneath, furnished with 

 a large, 2 — 3 mm long aërophore at the base beneath, incised to a wing 1 — VI-2 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. 



98. D. Galanderi (Hieron.) C. Chr. Revision nr. 16. 

 Area: Argentina, Minas Geraes. 



99. Dryopteris Millei sp. nov. 



Ecuador, in pascuis gelidis Andium Paluguillo, 3300 m, leg. A. Mille 

 nr. 125 (RB!). 



Rhizomate breve, decumbente, apice squamis lanceolatis castaneis hirtis onu- 

 slo. Stipitibus longissimis, usque ad 40 cm longis, fasciculatis, brunneo-stramineis 

 basi fuscescentibus et sparse squamosis, nitidis, decidue hirtis denique glabris, vix 

 ultra Vh mm crassis. Lamina lanceolata, utrinque attenuata, raro ad 20 cm longa, 

 medio 2—5 cm lata, rigide coriacea, pallide viridi. Rachi straminea, puis albidis 

 patentibus decidue hirta. Finnis 10 — 20-jugis, inferioribus sensim reductis more 

 D. oligocarpicae (typus I), saepe reflexis, medialibus maximis, raro ultra 2 cm longis, 

 sessilibus, horizontalibus vel leviter falcalis, apice integro acuto, ciliatis, coslis 

 utrinque el coslulis infra setis antrorsis selulosis, inter venas glabris el eglandulosis, 

 infra apicem integrum vel serratum ad alam 2 mm latam pinnatifidis. Laciniis 

 5 — 6-jugis, ovatis, subobtusis, obliquis, marginibus dense ciliatis revolulis, basalibus 

 aequalibus vel parum auclis. Venis 2— 4-jugis, indivisis. Soris infra medium venu- 

 laruni silis, rotundis, exindusialis; sporangiis glabris.
