626. Polypodium (Adenophorus) abietinum, Eaton (sp. nov) : 

 " parvum, delicatulum, glandulis clavatis rubris conspersum, caudice 

 paleaceo brevi repente ; rhachi flexuosa subcapillacea ; frondibus 

 ovato-oblongis pinnatis ; pinnis oblongis ad costam capillaceam pinna- 

 tisectis; segmentis 9-15 anguste spathulatis venulam unicam ad 

 apicem soriferam excipientibus ; soris latitudinem segmentorum multo 

 excedentibus. — Hawaii (Brackenridge, mixed with P. hymenophyl- 

 loides) ; Oahu, or trees 3,000 feet above the sea (D. D. Baldwin) ; 

 Hanalei, Kauai (M. & B.). — Fronds 1-3 inches high, very delicate, 

 apparently bipinnate, the pinnules less than a line long, and about one 

 sixth of a line broad, the sorus near the end, and nearly three times 

 the width of the pinnule. Perfectly distinct from P. hymenophylloides, 

 and much more delicate than P. tamariscinum, from which its hairlike 

 flexuous rachis will also distinguish it." Eaton, mss.
