930 CHARACTERS OF TRIBES AND GENERA. 
Oss.—A native of the West Indies and many parts of 
tropical America, the East Indies, Malayan, Java, Philippine, 
and Fiji islands, tropical West and South Africa, and East 
African islands. As might be expected, this wide geo- 
graphical range has led to this Fern being described under 
five generic and eight different specitic names, 
** Sort punctiform, rarely linear, naked, or included under 
an universal indusium. 
Sect. 6.—SrRvTHIOPreRrEs. 
Sori punctiform, included under an universal indusium. 
121.—Srrvurmiopreris, Willd. (1810). 
Onoclea, sp. Hook., Sp. Fil. 
Vernation fasciculate, erect, sub-arboroid. Fronds dimor- 
phous, 1 to 3 feet high, the sterile lanceolate, pinnate, 
pinne lanceolate, sessile, 4 to 6 inches long, pinnatifidly 
lobed, venules in the lobes pinnate. Fertile contracted, 
produced in a compact fascicle, from the centre of verna- 
tion, shorter than the sterile, revolute, the opposite margins 
conniving, forming a universal indusium (siliquaform). 
Veins pinnate, venules short. Receptacles punctiform, 
lateral, pedicils of the sporangia concrete. Sori confluent, 
irregular, or in a transverse row. `

Oss.—This genus agrees in habit and normal structure 
with the bipinnatifid species of Phegopteris, differing only 
in the fertile fronds being contracted as in Lomaria. 
It is represented in Europe by S. germanica, and in 
North America by S. pennsylvanica, and in India by S.
