HEMIONITIDBa;. llX.. 



Veins uniform, from a costa, everywhere anaBtomosing and form' 

 ing unequal hexagonal, more or less elongated, areoles. 



SVonds cordate sagittate palmate or pinnate, herbaceous or 

 coriaceous, proliferous, the fertile taller. Rhizome short erect 

 or creeping. Sori continuously reticulated, often becoming con- 

 fluent. — A small well-marked genus, as here limited, distinguish- 

 ed by the uniform and universal reticulation of the sori.

(c) Veins pinnate, venules reticulated, without free veinlets, 



81. DICTYOCLINE, Moore, Gard. Ckron. 1855, 854. 



Sori non-indusiate, narrow-linear, superficial on the anasto- 

 mosing venules ; the receptacles therefore reticulated. Veins pin- 

 nate from a central costa; vemiles transversely anastomosing, 

 forming two or three series of roundish-hexagonal areoles be- 

 tween the primary veins. 



Fronds coarse, herbaceous, pinnate with 3 — i pairs of pinnte j 

 the veins very hairy. Sori reticulated between the primary veins. 

 Rhizome short thick decumbent. — This plant has the fructifica- 

 tion of Semionitis, except that the sori, instead of being univer- 

 sally reticulated, only occur on the venules between the primary 

 veins, which latter are not soriferous. The aspect of the plant 

 approaches that of some of the larger species of Aspidimn, 

 while the venation is nearly that of some kinds of Foecilopteris. 

 It is the only hemionitidoid genus with pinnate venation.
