FEBNS OF THE MALAY-ASIATIC REGION. ( J 



Angiopteris augustifolia Presl is the commonest Philippine species. Fronds 



up to S in long, the pinnules green on both surfaces, typically about 13 cm long. 

 less than 1 cm broad, apex finely serrate: recurrent veinlets evident; sori of ."> 

 or sporangia. A. caudata de Yr.. does not seem to be more than a form of 

 this, with especially pubescent axes. 



Angiopteris pruinosa Kze. (as construed by Christ) is a beautiful plant 

 with fronds dark green above and bluish-white beneath, sori of about S sporangia 

 close to the margin, and the tine apex obscurely toothed, the base not cordate. 

 It is found in the Visayas and north to central Luzon; -it does not seem to me 

 identical with the Javan plant of Kunze. 



Angiopteris similis Presl, described from Java and recently found in Minda- 

 nao, has pinnules up to 18 cm long and 21 mm broad, seriate only on the sterile 

 tip. pale green beneath, with very line recurrent veinlets and dark brown sori. 



Angiopteris cartilagidens Christ (Plate IV) is a Benguet plant, with the 

 pinnules everywhere prominently and usually very sharply toothed, recurrent 

 veinlets conspicuous but short, and sori of 8 to 12 sporangia well inside the 

 margin. 



A. crassipes Wall, is an example of the species without recurrent veinlets. 

 It extends from Nepal and Burma to Japan. 



2. MACROGLOSSUM Copeland. 



Caudex globose; fronds very large, simply pinnate: recurrent veinlets 

 none; sori about 40; sporangia borne on the specialized, convex margin of 

 the pinna?. A single species. 



Macroglossum alidae Copel. Philip. Journ. Sci. Bot. 3 (1908) 343. (Plate 

 V.) 



Fronde suberect. about 3 m high; pinnae attached to raebis by a pul- 

 vinus, up to 50 cm long, (I em wide, abruptly narrowed to the caudate 

 tip, base rounded, coriaceous, glabrous. 



Borneo (Sarawak, Bidi). 



3. ARCHANGIOPTERIS Christ et Gies. 



Frond simply pinnate, pinna 1 with swollen pulvini, few; veins free: 

 sori long, midway between costa and margin; sporangia very small (for 

 tbis family) and numerous; scales of the indusium persisting as a white 

 line along the middle of each sorus. A single species. 



Archangiopteris henryi Christ et Gies. (Plate VI.) 



Stipe and stalks of pinnae finely scaly; pinnae 5 to 12, stalked above the 

 pulvini, about 20 cm long by 4 cm broad, acuminate, serrate toward the 

 apex, glabrous, herbaceous; sori on most veins except at base and apex 

 of pinna; sporangia up to 160 in a sorus.
