Var. Lyallii, Hook. — This form is intermediate between acutely pin- 

 nate states of A. lucidum (or A. obtusatum) and the less-divided forms of 

 A. Shuttleworthianum. 



Coastal rocks, Sunday Island. 



Asplenium flaccidum, Forst. f. 



Epiphyte in forest, Sunday Island. 

 New Zealand, Australia, Polynesia. 



Variety. — Fronds oblong-lanceolate, pendulous, 50-60 cm. long. Epi- 

 phyte in wet forest, Sunday Island. 



Asplenium Shuttleworthianum, Ktze. 



A very variable species. Fronds broadly ovate, 3-4 pinnate, 30-50 cm. 

 long, 20-25 cm. broad, coriaceous, yellowish-green, erect or pendulous. 

 Sori copious, short. The segments are sometimes reduced to the bare 

 costse, expanding only to support the sori. In the typical form the secondary 

 pinnae are lanceolate, deeply pinnatifid or the lower part pinnate ; seg- 

 ments linear-spathulate, divided into two or more lobes which are linear, 

 obtuse, + 1"5 mm. across. Sori 2-4 mm. long. 



Inland rocks, Sunday Island. Scrub, Meyer Island. 



Polynesia. 



Variety. — Primary pinnae ovate-lanceolate, deeply pinnatifid above, pin- 

 nate below ; the secondary pinnae stipitate, oblong, cuneate at the base, 

 obtuse, deeply serrate ; segments linear, obtuse, the lower ones two or more 

 lobed at the tip. 



Coastal rocks, Sunday Island. 



The typical form of Asplenium Shuttleworthianum appears to be derived 

 from A. obtusatum or A. lucidutn through this variety and A. lucidum Lyalli. 

 In A. Shuttleworthianum the frond lamina is reduced to its utmost limit.
