Fronds of membranous texture ... ... 2151 



2151. Fronds simply pinnatilobed or some entire. 



Perceptibly fragrant, chiefly on stems and branches of trees, 

 also on trunks of arborescent ferns ; root-stock widely 

 creeping ; fronds much decurrent along the stalk, thir 

 lobes often semi-lanceolar and generally few only, seldom 

 much elongated ; venulation hardly prominent, reticular ; 

 fruit-masses orbicular, distant, biseriate. 



P. scandens. 

 Fronds repeatedly pinnate. 



Tall ; root-stock creeping ; fronds very long and also of ample 

 breadth, mostly tri-pinnate, much beset with short often 

 glandule-bearing hairlets, usually rather membranous, but 

 occasionally also somewhat rigid, broadest towards the 

 base ; stalk somewhat rough ; ultimate pinnules almost 

 semi-elliptical, from deeply to slightly but always bluntly 

 lobed, often reflexed at the margin ; fruit-masses rather 

 small, often approaching towards the middle of the pin- 

 nule, though singly near a sinus, occasionally somewhat 

 concealed under a recurved lobule, sometimes almost 

 confluent ; spore-caselets on conspicuous stalklets. 



F. puuctatum. 



HYFOLEFIS, 



2152. Fruit-masses placed basally each into a sinus of the 



ultimate frond-lobes. 



Tall ; root-stock creeping ; frond long and of ample breadth, 

 mostly rather flaccid, tri-pinnate, somewhat beset with 

 very short hairlets ; ultimate pinnules or segments almost 

 semi-lanceolar, from deeply to slightly lobed ; fruit-masses 

 strictly marginal, never reaching towards the middle of 

 the pinnule ; fruit-cover somewhat renate, only at and 

 towards its upper margin membranous ; spore-caselets on 

 conspicuous stalklets. H. tenuifolia. 



DAVALLIA. 



2153. Length of the fruit-cover much greater than its 

 breadth. 



Hardly tall; root -stock far - creeping ; frond very firm, 

 generally somewhat deltoid in outline, glabrous, bi- or tri- 

 pinnate ; pinnules or segments indented or pinnatifid, 

 gradually much narrowed upwards, the ultimate lobes 

 often excised at the upper end ; cover of fruit-masses 

 longitudinally adnate, thus only terminally open, hemi- 

 ellipsoid, denticularly overreached by their pertaining 

 lobes ; spore-caselets on conspicuous stalklets. 



D. pyxidata.
