Hymenolepis, Kaulf. Emm. Fil, 14G. 
(Hyalolepis, Kunze ; Macroplethiis, Presl.) 
Sori superficial, linear-elongate or linear oblong, on the contracted apex of the fronds ; the receptacles contiguous to and coale- 
scent with the costa, sometimes covered while young by the revolute margin ; Veins indistinctly pinnate from a central costa or nearly 
uniform, venules compoundly anastomosing, forming crowded irregular areoles, from which proceed variably directed, included free veinlets. 
Fronds simple opaque, linear lanceolate the apex fertile contracted or curved — Rhizome creeping. (Moore.) 
1. Hymenolepis spicata, (Presl.) Rhizome creeping fronds simple opaque linear lanceolate, the apex contracted and soriferous on 
the imder side, much curved veins obscure.

Gymnopteeis, Bernhardt Schrade)-'s of Bot. 1800, II, 121. 
(Leptochilus, Kaulf uss ; Dendroglossa, Presl.) 
Sori superficial, non-indusiate, linear continuous, at length effuse ; the receptacles contiguous to the costa of the contracted 
fronds, often occupying nearly the whole under-surface, sometimes double on each side the costa. Veins pinnate from a central costa, the 
venules compoundly anastomosing, forming irregular areoles, from which proceed free divaricate veinlets, those of the fertile fronds much 
less developed. 
Fronds, simple, pinnatifid, or pinnate, dimorphous ; the fertile much contracted. Rhizome short creeping. (Moore.) 
1. Gi/m7i027teris querci/olia, (Bernh.) Caudex creeping, fronds ternate, sterile ones membranaceous, subciliate, the lateral ones 
small subcordato-lobate, sessile, unequal sided, the middle one much larger, petiolate, oblongo-ovate sinnately lobed, fertile fronds, on a 
long slender stipe which is squamose below, pinnas small narrow linear. Bernh., Presl., Tent., Pter., p. 'S.AA ; Acrostichum qnerci/ulium,

2. Gymnopteris Feci, (Moore.) Caudex creeping, fronds on long .stipes, dark green glabrous shining subcoriaceo-membra- 
iiaceous, lanceolate acuminated, fertile ones much contracted, sori contiguous to the costa forming a broad line of each side of it or often 
from the greater contraction of the frond occupying the whole under surface. Leptochilus lanceolatus, Fee. 
Very common in all alpine and .subalpine forests on the western side of the presidency, growing on rocks and trunks 
of trees.
