(3) C squaiuiilosn, Miefon., in Hedwi., LVII, 318; (? C. sub- 

 cordata, Copel, forma or var.). 



Very near C. subcordata Co'pel. but the under surface pilose with 

 scattered, articulated hairs. 

 Lu2on. 



(4) C inacro|>hy93a, lUet'on., in Hedwi., LVII, 291 ; C. fraxinea, 

 Diels, var. Gopelandi, Christ, in Philipp. Journ., IF, 171; Gymnogramma 

 javanica, Bl, var. macrophylla, BL, Flor. Jav., II, 95; Fee, Gen. Fil., 

 167; — var. sumatrana, v. A. v. R., in BuH. Btz., 1917, XXIV, 2. 



Fronds simply pinnate; pinnae entire or subrepand, cuneate to 

 rotundate-cuneate at the base, the largest 20 — 30 cm. long, 4 — 8 cm. 

 broad ; vein tips straight or falcate, terminating in a more or less elongated 

 bundle of sclerotic cells reaching or nearly reaching the cartilagineous 

 edge consisting of 4 or more rows of sclerotic cells; surfaces naked. 



Forma typica: Pinnae elongate-lanceolate, the cartilagineous edge 

 rather thick, more or less reflexed or recurved, the apex subabruptly 

 acuminate, the acumen 1 — 3 cm. long. — I cannot distinguish from this 

 rar. Copelandi (Hieron., 1. c, 292). — Java.i Luzon. 



War. sumatrana: Pinnae elliptical, the cartilagineous edge 

 rather thin, flat or hardly reflexed, the apex abrubtly cuspidate, the 

 cusp 2 — 4 cm. long. — Sumatra. 



(5) C interuiedia, Hieron., in Hedwi., LVII, 301. 

 Fronds pinnate; lower pinnae forked, or pinnate with 1 — 8 pinnulae 

 on each side below the terminal one; pinnulae Unear-lanceolate or 

 linear-oblong, cuneate or rotundate-cuneate at the base, serrulate, often 

 more coarsely serrate at the gradually acuminate to abruptly cuspidate 

 apex; serratures deltoid or falcato-deltoid, spreading or arcuate-ascending; 

 surfaces naked or the under surface provided with scattered, articulated 

 hairs ; vein tips terminating in an elongated, rather narrow, straight or 

 alcate bundle of sclerotic cells produced into the serratures and whether or 

 not reaching the marginal strand consisting of 2 — 3 rows of sclerotic cells. 

 — Very variable, with the forms passing gradually into each other. — 

 Backer's No. 9742, from Java, probably a form of this species, agrees 

 very well with Hieronymus' diagnosis ; the hairs of the under surface, 

 however, are not bulbous at the base.
