In iii«' earJj i ,;,n "' May, 1903, aud again during the latter pan of the same 

 month in 1904, the writer s] era] days in the rtclnltj of Mount Diablo, 



en both occasions staying at Hollymonnl (altitude about 7~.n meters) by kind 

 permission of the owner of this beautiful estate, w. p, Purdon, Esq., of K 

 t«>n. Among tin- extensive collections made there la a series of specimens 

 Including the connecting forms between the extremes shown by Sloans in 1 1 ■ • * 

 two figures cited above; having regard for which there is no alternative but 

 to combine all under a single name, This is the conclusion at whirl, Jenman 

 arrived in his later work, and be published a good description of the species 

 in this broad Bense in 1896 under the name Sephrodium serrulatum Jenm. 

 i /. c), Oddlj enough, however, ho yet made use of the Swartzian name 

 atplcnioides for quite a foreign group of plants, describing under the name 

 Nephrodium asplenioides Baker several different forms, of which at least a part 

 are associable with Dryopteris radicans (L.) Maxdn of the present paper (p. 

 190). That Jenman should follow Baker in misapplying the name asplenioidc* 

 is rather remarkable, in view of his having examined Sloane's specimens in the 

 British Museum !> and his having drawn a proper diagnosis of the species under 

 the name Vephrodium serrulatum Jenm. i /. c), which description certainly 

 includes the original asplenioides >>f Swartz, 



The reference of Polypodium lunanianum Beward to i>. serrulata Is, from 

 description, doubtful. 



The true />. serrulata is apparently confined to Jamaica. The following 

 specimens, showing a very wide degree of variation, as described by Jenman, 

 are In the r. s. National Herbarium: 



Jamaica: Vicinity of Hollymount, Mount Diablo, altitude about 750 meters, 

 Mamon 1878, 1890, 1893, 1908, 1923, 1925, 1952; Underwood 1890. 

 Hartford and adjoining properties, near Priestmans River, altitude 

 To to 300 meters, if axon 2514. Vicinity of Mandeville, Maxon i_* r. 7 1 . 

 Goniophlebium ampliatum Maxon. nom. nov. 



Polypodium gladiatum Kunze, Linnaea 9: 45. L834, not Veil. 1827. 



It has been customary to refer /'. gladiatum Kunze. founded upon specimens 

 collected in the interior of Cuba by Poeppig, to Polypodium {Qoniophlebium) 

 attenuatum II. & B., 1M<>. the latter a rather uncommon species described 

 originally from plants collected in Venezuela and Brazil with mention of 

 Sehkuhr's plate li. representing Guiana specimens. The Cuban plant, how- 

 ever, seems to differ constantly in the shape of the pinna 1 , these very long 

 attenuate and falcate, narrowed at the base and even Bubpetiolate, the lower 

 and middle ones essentially free and only the uppermost adnate or slightly 



decurrent, ami in the more numerous deeply Impressed or pustulate sorl com- 

 monly borne in four rows. The margins also are conspicuously undulate, 

 especially iu the fertile fronds. The following specimens, which agree with :i 



portion of the type collection in the herbarium of the New York Botanical 

 Garden, show no more than a normal amount of variation.

''The sioane specimens were reported on by Jenman in i ss <"> (Journ. Bot. 24. 



36). At that time he was inclined to regard the two extreme forms as possihly 

 representing twit distinct Bpecies; from this position he later receded, as Stated.
