84 CHEILANTHES. 



but then there are inteimcdiate foiins which seem to combine them. I 

 cannot agree with Kunzc in saying of it, "a Ch. Icnuifolia, Sw., abunde 

 d\Seilfio7i(le memhranacca : " for our specimens are, except those in a very 

 young state, more rigid. That author also notices its affinity wiih Ch. rti- 

 pestris, Wall., — which latter is true (enuifolia. 



13. Ch. micropliylla, Svv. ; caudex subiepent, stipes rather 

 short and rachises dcciduously ferrugineo-pubescenl or hir- 

 sute, fronds lanceolate pubescent or glabrous elongate lan- 

 ceolate bi- rarely subtripinnatc, pinntc lanceolate, pinnules 

 oblong obtuse entire or more or less crenate or pinnatifid, 

 involucres copious rounded or elongated frequently much 

 confluent.— ^V. Syn. Fit. p. 127. IVil/d. Sp. PI. v. p. 458.

 Salto and Panama, Tweedie. — To say that this is a variable species, is only 

 what may be said of almost all Ferns : and I do not see that any the most 

 minute description can meet the difficulties of the case : for they rather 

 tend to confuse and to mislead. The general form of the frond is tolera- 

 bly well expressed in Plumier, though on his usually exaggerated scale : 

 but there are some slates that bring our species into near relationship with 

 Ch. tenmfolia : our largest specimens on the other hand have an affinity 

 with some states of Hypolepis spectabilis. The involucres are particularly 

 variable, sometimes short and orbicular, at other times linear and continu- 

 ous, approaching, as so many of these plants do, to Allosorus : — this depends 

 doubtless much on the entireness or indentation of the pinnules. Our El 

 Paso specimens from Mr. C. Wright, are small, quite glabrous (not from 

 age), and the caudex is decidedly creeping. They may prove a different spe- 

 cies. Galeotti's n. 6564, though rather small, has the pinnules larger than 

 usual. Mr. Seemaun's from Sierra Madre, has some fronds with the invo- 

 lucres continuous ; others with the sori all small and distinct. 



14. Ch. Tiveediann, Hook. ; caudex a good deal creeping 

 horizontally, clothed with subulate brown bristly scales, sti- 

 pites scattered on the caudex short in proportion to the frond 

 slender ebeneous a little scaly towards the base, fronds quite 

 glabrous a span to a foot or l^^ foot long linear-oblong bipin- 

 nate, pinnae short distant oblong or ovate, pinnules membra-
