34. DAVALLIA. § 2. COLPOSOBIA. 223 



Forma minor: Fronds smaller, deltoid, + 15 — 25 cm. long, mostly 

 as broad, much acuminated, as are the pinnae. Indusia usually somewhat 

 elongated, the apex partly truncate partly rounded. 



(II j D. clecurrens, uu. 



Indusium as long as broad or somewhat longer than broad. — 

 Resembles D. divaricata Bl. in the shape and position of the sori, but 

 the fronds less divided. The Sumatran plant determined by Baker is D. 

 sumatrana Copel. — See No. 6a. 



(12) D. elata, Spr. 



A specimen gathered in Amboina differs from Hooker's plate in 

 having the adnata basal portion of the indusium subsemiorbicular, the 

 free apical portion triangular with rather straight edges, and the spurious 

 veins less numerous and less distinct. 



(12f0 D. papuana, Copel., in Philipp. Journ., VF, 81. 



Stipes + 30 cm. long, clothed at the base with narrow, ferrugineous 

 scales. Fronds deltoid, + 45 cm. long, nearly 4-pinnate. Lower pinnae 

 deltoid, + 30 cm. long, acuminate, with the rachis narrowly winged 

 towards the apex. Pinnulae ovate, obtuse, with the largest segments 

 incised again, the ultimate lobes or teeth more or less cornuted. Texture 

 coriaceous; rachis and surfaces naked; spurious veinlets present. Sori 

 intramarginal; indusium as broad as long or narrower, the apex often 

 rounded, sometimes obtusely and l>roadly cuspidate. 



Neto Guinea.

(15) D. bullata, Wall. 



Rhizomes scales pale, narrowly subulate, recurved, ciliate, narrowed 

 suddenly from a suborbicular, adpressed, peltate base, the ciliae at length ; 

 decidous soriferous lobules (teeth) short and broad, broadly sessile or 

 cuneately narrowed at the base; indusium relatively short and broad, 

 semicupuliform, + 1 '/i — 2 X as long as broad, with usually a horn on 

 the outside, the apex whether or not reaching the margin of the lobule.
