PAPUAN FERNS.

16. P. musaefolium Bl. 
Nos. 148, 190, Ambasi. 
New Guinea and Malaya. 
The species is wonderfully rich in forms. 
DENDROCONCHE Copeland genus novum. 
Genus a Polypoclio ob frondes non ad rhizoma articulatas, dimor- 
phas, steriles ut Drynariae humiferas, integras separandum; frondis 
fertilis parte inferiore sterile, oblata, parte superiore valde elongata, 
lineare ; venulis anastomosantibus. ISTomen ex SevSpov, arbor, et kojxo? 
concha in formam frondium sterilium illudens. 
1. D. Annabeliae (Forbes) Copel. comb. nova. 
Pohjpodium Annabeliae Forbes in Journ. of Bot. 26 (1888) 33. 
This plant is without any reasonable doubt descended from Polypodium musae- 
folium Bl., or some form very close to it; it is generically to be separated because 
aberrant in such important details that its inclusion in Polypodium would be 
decidedly too inconvenient. Drynaria has the same ancestry; but Drynaria and 
Dendroconche represent distinct lines of development, and therefore are not to be 
united, unless with the parent. 
An excellent illustration accompanies the original publication of the species. 
CYCLOPHORUS Desvaux. 
1. C. adnascens (Sw.) Desv. 
No. 19 7, Ambasi, common. 
Polynesia to India. 
2. C. stigmosus (Sw.) Desv. 
No. 116, Waria River, altitude 300-600 m; No. 2 49, Ambasi. 
Malaya, India. 
3. C. Lauterbachii (Christ) C. Chr. 
No. 846, Lakekamu. 
Known only in New Guinea. 
The sterile fronds are broader toward the base than is typical; and the sori 
are not close enough to the margin to be visible from the upper surface. The 
midrib is visible above and below. 
DRYNARIA (Bory) J. Smith. 
1. D. sparsisora (Desv.) Moore. 
Nos. 207, 231, 242, common. 
Fiji and tropical Australia to Ceylon. 
2. D. quercifolia (L.) J. Sm. 
No. 32 7, Ambasi. 
Same range as the last. 
The segments are connected by a broader wing than are those of the specimens 
sent, of D. sparsisora. 
3. D. rigidula (Sw.) Bedd. 
Nos. 127, 225, 296, at moderate altitudes. 
Same range as the preceding.
