 Porto Rico, cited by Hooker and by Urban, respectively, as L anisophyllum,

 aame, withoul comment, along with Linden's 1887. 



.1. sarcodes is allied to .1. anisophyllum Kunze d and A. sanguinolentum 

 Kunze, the former an African species, the latter South American. .1. anis- 

 ophyllum, as shown by two complete specimens oul of the series at hand, 

 has the rhizome ere.-t ias in .1. sarcodes), nol creeping, as redescribed by 

 Mettenins'. whose description is otherwise excellent. It differs from l. sar- 

 codes in its firm light-colored subterete stipe and rachis (these could hardly 

 have been carnose, as in .1. sarcodes), in its delicate membranous texture and 

 apparent venation, and in having the margins deeply serrate (instead of lightly 

 crenate). The fronds are considerably larger and terminate much less 

 abruptly than in .1. sarcodes; they are also sometimes proliferous. 



A. sanguinolentum Kunze,' in the typical form figured by Mettenins/ is 

 known to the writer only from Regnell's III 1468, from Caldas, province of 

 Minas Geraes, Brazil (N). II. II. Smith's no. ipjs from Santa Marta, Colom- 

 bia, altitude about 1,650 meters (N) is similar to this in delicate texture 

 and marginal serration, but has the superior base of the pinna? less auriculate 

 and scarcely excised at tin; inner margin. Both specimens have the rachis 

 dark and compressed, as in .1. sarcodes. They approach .1. sarcodes only 

 through Wright's Monte Verde specimen, which is the most extreme of those 

 cited under sarcodes and which has the pinnae of more delicate texture and 

 more deeply crenate-serrate than the others. None of the Cuban and Porto 

 Rican plants have the pinnae auriculate or even subauriculate or excised at the 

 inner margin. 



.1. sarcodes is thus nearest related to the continental .4. singuinolentum, 

 being distinguished ordinarily by its very coriaceous texture, by having the 

 pinme rounded-truncate at the superior base (even slightly overlapping the 

 rachis iu some specimens), by its lightly eremite margins, and by its concealed 

 \ enation. 

 Cheilanthes aemula Maxon, sp. nov. 



Fronds about 50 cm, high, clustered; rhizome short-creeping, thickly cov- 

 ered with narrow ferruginous chaff: stipe -- to 25 cm. Ion-, stent (2 to 2.5 

 mm. thick), more or le<s flexuose, blackish or dark purplish brown, rigid. 

 terete; lamina subcoriaceous, ."»<> to 35 cm. long, 20 to 22 cm. broad at base, 

 broadly triangular, very deeply quadripinnatifid below, otherwise tripinnate 

 nearly throughout; primary rachis similar to the stipe, its upper surface 

 and that of the secondary rachis covered with a scurfy jointed pubescence; 



" Wright 845 was reported firsl by Eaton (Am. Journ. Sci. II. 27: P.*:*. 1859) 

 as "Asplenium, Balicifolio, L. affine," subsequently (Mem. Am. Acad. II. 8:205. 

 1860) as .1. anisophyllum Kunze. It is cited under the last name by Hooker 

 (Sp. Fil 3: 112. iMiin.
