9. WOODWAEDIA. 



Sori oblong or shortly linear, more or less immersed in the substance of the 

 frond, near and parallel to the midrib of the pinna or of its segments, and 

 sometimes confluent when old, with a stiff longitudinal indusium. — Stem or 

 rhizome decumbent or creeping. Fronds pinnate or bipinnate ; the stipes 

 scaly at the base. 



A small genus, dispersed over the temperate regions of the northern hemisphere, more 

 rarely penetrating within the tropics. 



Pinnse of the fertile fronds 3 to 7, entire i. W. Harlandi. 



Pinnse more than 7, pinnatifid i. W. japonica. 



1. W. Harlandi, Hooh. Spec. Fil. iii. 70 ; Ml. Exot. t. 7. Ehizome 

 creeping, with small subulate scales. Fronds ^ to 1^ ft. high, including the 

 long stipes. Fertile pinnae 3 to 5, lanceolate, 4 to 8 in. long, more or less 

 decurrent or confluent at the base, rather rigid, entire or serrulate. Veins re- 

 ticulate. Sori at first distinct, at length confluent along both sides of the 

 midiib, and sometimes with short lateral sori diverging from it. Ban-en 

 fronds usually cordate at the base, simple or deeply 3-lobed, the segments 

 shorter and broader than in the fertile ones. 



Hongkong, Harland, Lorrain ; among long grass and low bushes on the first hiU going 

 to -Victoria Peak, Wilford. Not known from elsewhere. 



2. W. japonica, Sm).; Hooli.Spee.Ml.m. ^9. Ehizome creeping, with 

 copious lineai--lanceolate acuminate scales. Fronds 1 to Ij- ft. high, pinnate. 

 Pinnse about 6 to 8 pair, aU distinct, or the upper pair- confluent with the 

 terminal one, pinnatifid with short obtuse lobes, all ending in a lanceolate en- 

 tire point. Veins reticulate, with a principal vein corresponding to each lobe. 

 Sori linear, distinct or confluent along the midrib of each lobe, more rai-e 

 along the midrib of the pinna, and only in its upper portion. Barren fronds 

 smaller, with fewer and broader pinnse than the fertile ones.— Blechmm ja- 

 ponioum, Linn. ; Thunb. Fl. Jap. t. 35. 



On HUs and in the Happy Valley, TJrquUrt, Harland. On the Chinese continent and 

 in Japan. 



10. LINDSJEA, Dryand. 



Sori linear, continuous or interrupted along the margin of the frond-seg- 

 ments with a longitudinal indusium opening along the outer edge (next the 

 margin) —Ehizome usually creeping. Fronds pinnate or bipmnate very rarely 

 (in species not Chinese) simple. Veins forked or reticulate.
