 Tandeu's no. 1SS7, from Cuba, and Siutenis* nos. 2()f»2, 4234b, and 6459, from 

 IV>rtu Kico, cited by Hooker and by T*rb;ni, respectively, as A. anisophj/JIum, 

 probably belong here; as does also Linden^s 1890 cited by F^e ^ under this 

 name, without comment, along with Limleifs 1SS7. 



A, sarvodes is allied to A. anisophi/JJi(m Kunze^ and A, sangmnoleniiua 

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

 ophyUam, as shown by two comi)lete si)ecimens out of the series at hand, 

 has tlie riiizome erect 



.Mettenius^, whoso description is otherwise excellent It difi'ers from A. snr- 

 codtH in its firm light-colored subterete sti])e and rachis (those could liardly 

 have been carnose, as in A. snrcodcf^), in its delicate membranous texture and 

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

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

 abrujjtly than in A. ^arcoden; they are also sometinu^^ ju'oliferous. 



A. sauguinolcntum Kunze,^ in the typical form figured by Mettenius/ is 

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

 Minas Geraes, Brazil (X). H. II. Smithes no, 1128 from Santa Marta, Colom- 

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

 and marginal serration, but has the superior base of t}\e pinna} less auriculate 

 and scarcely excis(\l at the inner margin. Both specimens have tlie rachis 

 dark and compressed, as in A. .sarcoJcs. They approach A, sarcoc/cv only 

 through "Wright's Monte Verde spec]m<"iu which is the most extreme of those 

 cited under sarcodc^s and which has the pimue of more delicate texture and 

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

 Kicau ])lants have tlie pinn;e auriculate or even subauriculate or excised at the 

 inner margin, 



A, mrcodes is thus nearest related to the continental A. singuinolcnium, 

 i>eing distinguished ordinarily by its very coriaceous texture, by having the 

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



rachis in some specimens), by its lightly crenate margins, and by its concealed 

 venation. 



Cheilanthes aemula Maxon, sp. nov. 



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

 ered with narrow ferruginous chaff; stipe 22 to 25 cm, long, stout (2 to 2.5 

 mm. thick), more or less flexuose, blackish or dark purplish brown, rigid, 

 terete; lamina snbcoi'iaceons, 30 to 35 cm. long, 20 to 22 cm. broad at base, 

 broadly triangular, very deeply quadripinnatifid bchnv, otherwise tripiniiate 

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

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



"^ Wright 845 was reported first by Eaton (Am. Journ. Sci. II. 27:199. 1S59) 

 as ''Asplenium, salicifolio, L. affine,^' subsequently (Mem. Am. Acad. II. 8:205. 

 1860) as A. anisophyUnm Kunze. It is citetl under the last name by Hooker 

 (Sp. Fil 3:112. 1860).
