188 36. WOODWARDIA, EUWOODWARDIA, ANCHISTEA. 



subfalcate pinnl. |~ in. 1., J in. br. ; texture coriaceous ; veins immersed ; main 

 rachis and that of the pinnae densely clothed throughout with ovate-acuminatft 

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

 Brack. Fil.U.S.Exp.p.\35. 



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 pinnae and pinnules. 

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

 lid. Veins forming always a series of costal arches, 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.l., 

 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 pinnae. Hk. Sp. 3. 

 p. 67. 



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

 Mexico, and Guatemala. 



2. W. orientals, 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 pinnatifi d 

 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. 



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. L, 6-9 in. br. ; pinnce linear-lanceolate, 4-6 in. 1., f-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 which margin the midrib of the pinnae 

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



Hab. Canada, United States from Vermont to Florida, Bermuda. 



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

 12-18 in. L, 9-12 in. br. ; pinnce lanceolate, often 6 in. L, 1-1| in. br., pinnatifid, 

 with lobes |~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. United by Dr. Hance with the last.
