P. setigerum — se-tig'-er-um (bristly), Blume. 



A stove species, native of Java, with entire (undivided) fronds Sin. to 

 12in. long and Jin. to fin. broad, borne on densely-tufted stalks 2in. to Sin. 

 long thickly clothed with long, soft hairs of a rusty-brown colour. They are 

 sharp-pointed at the extremity, and the lower part is narrowed rather suddenly; 

 they are of a somewhat leathery texture and thinly clothed on both surfaces 

 with long, soft hairs like those of the stalks. The numerous round sori 

 (spore masses) are disposed in long rows close to the midrib. — Hooker, Species 

 Filicum, iv., p. 171 ; Second Century of Ferns, t. 41. 



P. Sieberianum — Sie-ber-i-a'-num (Sieber's). 

 This is synonymous with P. cyathecefolium. 



P. simplex — sim'-plex (simple, undivided). A 

 variety of P. lineare. 



P. (Phymatodes) sinuosum — Phy-mat-o'-des ; 

 sin-ii-o'-sum (wavy-edged), Wallich. 

 This small-growing, stove species, native of 

 Malaysia, the New Hebrides, and the Solomon 

 Islands, is very distinct through its barren and 

 fertile fronds being totally dissimilar. The former, 

 Sin. to 6in. long and Jin. to lin. broad, have their 

 edge entire, whereas the fertile ones are longer and 

 have their edge undulated. Both fronds are of a 

 leathery texture and naked on both sides. Their 

 large, round or oblong spore masses are situated at or near the margin of the 

 frond, in which they are immersed. Fig. 61 is reduced from Col. Beddome's
