Poli/podium.] filices. 459 



the lateral ones diverging and half as long as the central one, all acuminate, 

 entire, thin and glabrous. Yeins reticulate, the primary branches diverging 

 from the midrib halfway to the margin. Son rather small, on the anastomo- 

 sing veinlets, 1 to 3 between each 2 primary veins. 



Hongkong, Champion, Harland ; in a wet shady situation at Little Hongkong, Wilford. 

 In Ceylon, Khasia, Assam, and the Philippines. 



6. P. granulostim, Presl, Rel. Hank. 24, t. 4,/. 2. Fronds 1 ft. high or 

 more, pubescent at least on the rhachis and principal veins, simply pinnate. 

 Pinnae 5 to 7 or sometimes more, oblong-lanceolate, acuminate, slightly fal- 

 cate, 4 to 5 in. long, entire, rounded at the base and shortly petiolulate. Veins 

 very prominent, the primary ones numerous, parallel, with regularly pinnate 

 transverse veinlets meeting in an intermediate line as in Meniscium. Son at 

 the junction of the veinlets, in a single row between each 2 primary veins in 

 the Hongkong specimens, more frequently (but not always) in a double row in 

 the Indian ones. — P. urophyllum, Wall. Catal. n. 299. Nephrodium glandu- 

 losum, J. Sm. in Seem. Bot. Her. 428. 



Hongkong, Hance ; in Water Ravine, Urquhart. In Ceylon, Khasia, Sikkim, the Malayan 

 Peninsula, the Archipelago, aud northward to Chusan. One or two of the peltate scales in- 

 termixed with the sori occasionally persist a long time, so as to have been mistaken for the 

 indusium of an Aspidium. 



7. P. cor (mans, Wall.; Hook. Til. Exot. tf. 91. Rhizome stout, elon- 

 gated. Fronds densely tufted, sessile, 2 to 3 ft. high or more, stiffly coria- 

 ceous, glabrous and shining, deeply pinnatifid or almost pinnate. Lobes nu- 

 merous, the longer ones lanceolate, acuminate, from 3 or 4 in. to twice that 

 length, divided almost to the rhachis in the centre of the frond, becoming 

 gradually shorter and more obtuse below the middle, until the frond again 

 expands into a cordate base often 6 to 8 in. broad, with short rounded lobes. 

 Veins prominent and parallel, starting from the midrib, and connected by 

 transverse reticulations. Sori in 1 row between each 2 primary veins. 



Near Victoria Peak, Wilford. In the mountains of northern and eastern India. 



8. P. tenericaule, Wall. ; Hook, in Kew Joum. Bot. ix. 353. Fronds 

 \\ to 2 ft. high, twice pinnate, with deeply pinnatifid pinnules ; the stipes 

 glabrous, not muricate, with a few brown scales at the base. Lower primary 

 pinnse 6 to 8 in. long, the upper ones passing into the pinnatifid apex. Pinnae 

 lanceolate, the longer ones 2 in. long, the principal veins bearing a few stiff 

 hairs. Segments oblong-linear; the lower ones deeply senate, the upper 

 short and entire. Sori 1 to 4 on each side of the midrib of the segment. 



Near the church of Victoria, Wilford; in Tank Ravine and Washerman's Ravine, Urquhart. 

 In India, from Concan to Assam, in Singapore and the Archipelago, and northward to the 

 Philippines and S. China. 



20. BRAINEA, Hook. 

 (Bowringia, Hook ; not Champ.) 



Sori at first short and distinct, parallel to and near the midrib, at length 

 usually confluent along the midrib and covering nearly the whole surface of 

 the fertile segments. Indusium none. 



A genus limited to a single species.
