Hab. Sandwich Islands ; gathered lately by Dr. Hillebrand.-i-Very different in habit 

 from No. 1, and the rows of fruit are shorter and not quite close to the inconspicuous 

 midrib. 



Gen. 36. Woodwakdia, Sm. 



Sori linear or linear-oblong, sunk in cavities of the frond, placed in single 

 rows parallel with and contiguous to the midribs of the pinnae and pinnules. 

 Jnvol. subcoriaceous, the same shape as the sorus, closing over the cavity like a 

 lid. Veins furming always a series of costal arclies, for the rest free or anasto- 

 mosing. A small germs with fronds usually ample and bipinnatifld, which belts the 

 world in the North Temperate Zone, extending very slightly loithin the Tropic. 

 Tab. IV. f. 36. 



§ Euwoodwardia.. Fronds uniform, the veins forming at least one series of 

 areolations between the sori and the margin. Sp. 1-2.

 1., 12^^8111. br. ; pinnae lanceolate, the lower ones often 1 ft. 1., cut down below 

 within a short distance of the rachis into finely-toothed lanceolate pinnl. 1-1 J in. 1., 

 those of the under side the shortest ; veins anastomosing once outside the line of 

 fruit ; gemmce few and large, placed at the base of the upper pinnse. — Elc. Sp. 3.

2. W. orientalis, Swartz ; St. erect, densely clothed at the base with large 

 linear-lanceolate scales ; fr. 4-8 ft. 1., 12-18 in. br. ; pinnce lanceolate, sometimes 

 more than 1 ft, 1., cut down below nearly to the rachis into sinuated or pinnatifid 

 pinnl., sometimes 4 in. 1., those of the under side shorter and none at the base of 

 the pinnae ; veins anastomosing copiously outside the sori, upper surface of the 

 frond often producing copious gemmiferous buds. — Hk. Sp. 3. p. 68. 



Hab. Japan southward to Formosa. — Probably this ought to be joined with the 

 preceding.

 12-18 in. 1., 6-9 in. hr. ; pinnce linear-lanceolate, 4-6 in. 1., j-1 in. br., cut 

 down within one lin. or less of the rachis into linear-oblong lobes which are 

 2-3 lin. br. at the base, the lines of sori w^hich margin the midrib of the pinnae 

 often reaching low down in the lower ones. — Hk. Sp. 3. p. 69. 



Hab. Canada, United States &om Vermont to Florida, Bermuda.

 rachis, the line^ of sori which margin the midrib of the pinnse confined to the 

 upper part of the upper ones. — Hi. Sp. 3. p. 69.
