188 36. WOODWARDIA, EUWOODWAKDIA, ANCHISTEA. 



subfalcate pinnL J- in. 1., J in. br. ; texture coriaceous ; veins immersed ; main 

 rachis and that of the pinna? densely clothed throughout with ovate-acuminate 

 dark-brown scales. Gaud. Voy. Bonit. Atlas, t. 2. Blechnum polystichoides, 

 Brack. Fit. U.S. Exp.p. 135. 



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

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

 midrib. 



GEN. 36. WOODWARDIA, 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 pinna? and pinnules. 

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

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

 mosing. A small genus with fronds usually ample and bipinnatifid, which belts the 

 world in the North Temperate Zone, extending very slightly within 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. W. radicans, Smith ; st. strong, erect, naked, scaly at the base ; fr. 3-6 ft. 

 1., 12-18 in. 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^ in. 1., 

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

 fruit ; gemmae few and large, placed at the base of the upper pinnse. HTc. Sp. 3. 

 p. 67. 



Hab. Madeira and the Canaries, Spain, Italy, Sicily, Northern India, Java, California, 

 Mexico, and Guatemala. 



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. ; pinnae 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 pinnse ; 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. 



Anchistea, Presl. Fronds uniform, the veins all free between the sori and 

 the margin. Sp. 3-4. 



3. W. Virginica, Smith ; st. strong, erect, 12-18 in. 1. ; fr. oblong-lanceolate, 

 12-18 in. 1., 0-9 in. br. ; pinnae linear-lanceolate, 4-6 in. 1., f-1 in. br., cut 

 down within 1 lin. or less of the rachis into linear-oblong lobes which are 2-3 lin. 

 br. at the base, the lines of sori which margin the midrib of the pinnse often 

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



Hab. United States from Vermont to Florida. 



4. W. Japonica, Swartz ; st. 6-12 in. 1., erect, scaly below ; fr. broadly ovate, 

 12-18 in. 1., 9-12 in. br. ; pinnae lanceolate, often 6 in. 1., 1-lJ in. br., pinnatifid, 

 with lobes J-f in. br., which reach half or two-thirds of the distance down to the 

 rachis, the lines of sori which margin the midrib of the pinnae confined to the 

 upper part of the upper ones. Hk. Sp. 3. p. 69. 



Hab. China and Japan.
