or a whorl of fibres. — The type and the varieties are passing into each 

 other by intermediates which are difficult of determination. 



Forma typica: Main rachis naked; pinnae and pinnulae proportionally 

 long and narrow; costae fulvo-tomentose above, naked or sparingly buUato- 

 squamulose beneath; ultimate segments rather numerous; costulae and 

 veins beneath squamulose with scattered, caducous, small, bullate, laciniate- 

 flmbriafe scales; veins forked, the lower often 3-furcate, the higher simple; 

 sori occupying the lower '/i — "/3 of the lobes. 



War. squaiiiiilata : Costae and costulae squamulose on both 

 sides (?) but more copiously on the lower side, the scales flattish, ovate- 

 lanceolate, acuminate, ciliate-lacerate, adpressed, small, whitish, especially 

 the lower of the pinnulae intermixed with longer, linear ones; ultimate 

 segments relatively short and broad. 



far. densa: Costae above fulvo-puberulous, substrigose, beneath 

 naked or sparingly squamulose with very narrow, whitish, minute scales; 

 costulae naked, or sparingly squamulose with minute, caducous, ovate, 

 subbuUate scales ; veins mostly forked ; sori occupying nearly the whole 

 under surface of the lobes except the apex, at length confluent. 



War. microloba s Intermediate between the preceding and the 

 foUomng ; costulae buUato-squamulose between the sori, otherwise setulose. 



Var. isetiilosa : Costae hirsuto-tomentose above ; costulae provided 

 beneath with scattered, moderately long, pale, spreading, acicular setae 

 especially in the barren region; veins and sori as in the type. 



War. sqiiauauloisa: Like the preceding but the setae intermixed 

 with caducous, pale, rather flat, cihate-fimbriate squamules between the 

 sori; ultimate segments relatively long and narrow; veins naked, or 

 sparingly setulose with bristles shorter and finer than those of the costulae; 

 sori as in var. densa in the longer forms. 



War. celeltica: Pinnae and pinnulae relatively short and broad; 

 ultimate segments not numerous, 2 — 3 mm. apart. 



War. louge|»aleata: Main rachis scaly with long, linear-subulate 

 brown scales.
