518 APPENDIX. 62. CONIOGBAMMA. 



1. Hydathocles neither reaching the marginal strand of sclerotic cells nor 

 terminating in a bundle of sclerotic cells. 



2. Segments cuneate to rotundafe at the base. (1) C. fraxinea. 



S.3. Segments cordate to rotundate-truncate at the base. 



3. Segments naked beneath. (2)0. subcordata. 



3.3. Segments more or less sparingly pilose beneath. 



(3) C. squamulosa. 

 s.l. Hydathocles either reaching the m,arginal strand of sclerotic cells or 

 terminating in a more or less elongated bundle of sclerotic cells, lohich 

 may reach the marginal strand. 



* Segments entire or subrepand. (4) C. macrophylla. 



** Segments crenulate, serridate or toothed. (5) C. intermedia. 



(1) C fraxinea, IHels; Hieron., in Hedwi., LVII, 286; — var. 

 serrulata; Gymnogramma serrulata, BL, Flor. Jav., II, tab. XLII; var. 

 crenulata, v. A. v. R., in Bull. Btz., 1916, XXIII, 8. 



Stipes at best somewhat squamulose at the base, for the rest naked, 

 as are the rachises; fronds of young soriferous plants simply pinnate, of 

 adult plants 2-pinnate to sub-3-pinnate at the base; segments (leaflets) 

 herbaceous, gradually acuminate to abruptly cuspidate at the apex, 

 cuneate to rotundate at the base, bounded by a narrow marginal strand 

 consisting of 1 — 3 rows of pale-coloured sclerotic cells. 



Forma typlca: Edges entire or subrepand throughout; vein tips not 

 reaching the marginal strand. — Brit. India acros Ceylon and Malaya 

 to Formosa. 



War. lierriilata: Edges crenulate to serrulate below the entire 

 or repand acumen; vein tips not reaching the bases of the crenulations 

 or serratures. — Java. 



(2) C siibcorilaia, Copel., in PhiUpp. Journ., IIF, 823. 

 Stipes and rachises more or less sparingly provided with mostly 



caducous or rarely persistent squamules; fronds 2-pinnate; pinnulae 

 membranaceous, the apex proportionally shortly acuminate or cuspidate, 

 the base cordate to rotundate-truncate; edges serrulate or serrate except 

 at the very base, the acumen often more coarsely serrate ; surfaces naked ; 

 vein tips not reaching the marginal strand consisting of 2 — 3 rows of 

 sclerotic cells though often produced into the serratures, 

 Luzon.
