GENUS 48. LOMARIA. Sori and indusia linear, unit- 

 iog the vein tips or running them transversely. 

 Fronds simple or pinnate, dimorphous, the fertile 

 fronds or segments narrowly linear. Stipes with 

 3 to many vascular strands placed in a circle. 



Tribe V. Biechneae. Sori transversally oblong or linear, 

 distant from the margin, parallel to the midribs of the 

 fronds or their segments. Indusium of the same shape 

 as the sonis, not marginal, attached at the outer side 

 of the sorus, opening inwardly. 



GENUS 49. BLECHNUM. Sori long, linear, sometimes 

 interrupted, ± close to the midribs. Veins of 

 fertile fronds united near the base by subcostal 

 strands bearing the sori. 



GENUS 50. SADLERIA. Like genus 49, but the veins 

 of both barren and fertile fronds united near the 

 base. 



GENUS 51. DOODIA. Sori oblong, superficial, in one 

 or more rows on each side, not + close to the 

 midribs. 



GENUS 52. WOODWARDIA. Like genus 51, but the 

 sori in 1 row, immersed in cavities. 



Tribe VI. Asplenieae. Sori oblong or linear, attached to 

 the sides of the veins which unite the midribs or 

 main veins with the margin, therefore mostly oblique 

 to the midribs, rarely placed between the veins. In- 

 dusia of the same shape, springing from the veins on 

 the same side as the sori. 



GENUS 53. DIPLAZIUM. Stipes w»tb 2 ± flattened 

 vascular strands mostly uniting towards the apex 

 of the stipe (or higher) into a single diarchous 

 one ( \ / , V. W > U. U )■ Sori linear or 

 linear-oblong, the lower of each group of veins 

 mostly double.
