ENUMERATIO FILICUM PHILIPPJNAKUM, 407 



DiPLAZiUM, Sw.s Presl. 



130. Ti.porrectum.—Ksplemum porrectum, Wall Malacca? 



{n. 387.) 



131. D. deflexum, J. Sm.— Malacca ; («. 386.) 

 ii32. D. Sorzogonense^ Presl. — Leyte ; {n. 301.) 



Obs, The paleaceous rachis is the cliief character that distin- 

 guishes this from Diplaziwn striatum, a native of the West 

 Indies, which with the present, and some other nearly related 

 species, present difFe rent forms, according to the difference of 

 age or size of the fronds from which the specimens are taken, 

 and which circumstance has evidently led to the creating of 

 more than one species from the same plant ; for it has been 

 observed that the fronds of young plants are, for a certain 

 period only, pinnate, and yet appear perfect by being sori- 

 ferous, although at a subsequent period the same plant will be 

 found producing bipinnate or tripinnate fronds, five or six feet 

 in length ; thus one of the ultimate pinnae of such a frond is 

 analogous to the whole frond in the early or nascent condi- 

 tion of the plant. I have considered it necessary to notice 

 this on account of my having in the present enumeration 

 placed two or more very different looking specimens under 

 the same name. 



133. D. Schkuhrii, J. Sni. — Asplenium ambiguum, Schk. 

 Crypt, t. 75. a. non Svvartz, neque Raddi.— Malacca; («. 389.) 



Obs. Schkuhr has figured two distinct plants for the Asple- 

 nium ambiguum of Swartz; the one is the jpresent species, and 

 the other {t. 75. b.) is Gallipteris Malabarica of this enume- 

 ration. 



134-. D. affine, J. Sm. — Luzon; («. 167.) 



135. D. exiensum, J. Sm.— Luzon; (n. 170, 199.) Samar; 

 (n. 333, 336) ; Bohol ; {». 349) ; Malacca ; {n. 388.) 



0^-5. The specimens numbered No. 199, 333, and 338, are 

 not unlike Dlplazium grandifoUum from the \\'est Indies, but 

 I consider them different, and that they are young plants of 

 the species which produces the large bipinnate fronds, 

 numbered 170, 336, and 349.
