rather short, oblong, blunt, broadly crenate or coarsely toothed, 

 the crenations or teeth entire or generally crenate to serrulate ; 

 central pinnulae hastate to palmatifid, with the segments rather 

 short, oblong, blunt, similar to the terminal pinnulae but smaller, 

 the terminal segment somewhat larger; lower pinnulae similar 

 to the central ones but pinnate at the base, with the lower leaflets 

 similar to the central pinnulae but smaller. 



Forma elongata (this Bulletin, tab. III): Like the type but 

 the terminal pinnulae much elongated, narrowly linear or linear- 

 lanceolate, as are the terminal segments of the central and lower 

 pinnulae, the pinnae therefore relatively very broad; latéral segments 

 of the pinnulae not rarely subulate, and the teeth of the segments 

 sometimes so. — Amboyna (Rothert), Luzon and Negros (Elmer).

Hydroglossum.— Fronds wide-scandent, the rachis naked, dirty- 

 brown ; primary and secondary pétioles very short, shortly pu- 

 bescent. Pinnae 2 — 3-foliate. Leaflets stalked, dimorphous, the 

 barren ones lanceolate, ca 10—15 cm. long, ca 2 — 21/0 cm. broad, 

 simple, entire, narrowed very gradually towards the base and the 

 acute apex or the upper half suddenly contracted into a very 

 narrow, caudate fertile apex as broad as the fertile leaflets, the 

 very base provided with 1 or more very minute, nearly fi'ee 

 auricles; fertile leaflets much contracted, narrowly linear, 1—5 

 mm. broad. Texture thin-pergamentous, moderately diaphanous ; 

 surfaces naked ; costae prominent on both sides, dirty-brown ; veins 

 reticulate, very conspicuous, forming ca 6 rows of oblique areolae 

 between the costa and margin in the barren pinnulae. Spikes 

 numerous, approximate, shoit, hairy at least when young.

Chilst considers this species to be intermediate between 

 Angiopteris and Marattia because of the présence of spurious 

 (récurrent) veinlets; in the doublet of Versteeg's No. 1681 occurring 

 in the Buitenzorg Herbarium, however, I could not find any trace 

 of a spurious veinlet, even when the leaflets were made trans-
