inches long and as well as the main rachis ebeneous, fronds 

 3 — 6 inches long glabrous thick-membrauaceous rather soft 

 and flaccid deltoid-ovate tri-quadripinnate, pinnules all ob- 

 long-obovate or subcuneale entire or lobed auricled at the 

 base above and more or less deeply pinnatifid all of them 

 decurrent so as to form a winged rachis, lobes oblong-ovate, 

 sterile pinnules and lobes the broadest and penniveined, all 

 of them crenate at the margin, involucres on the teeth of the 

 crenatures broad membranous suborbicular rarely free (the 

 edge very thin and fringed) mostly combined and forming a 

 continuous lobed or broadly crenated involucre extending all 

 round the margin. — H. B. K. Nov. Gen. et Sp. Am. i. p. 18,

 able and easily distinguished plant, and pretty widely distributed, even well 

 figured (both by Humboldt and Galeotti), yet strangely misunderstood. 

 Kunze, who distributed Poeppig's Allosorus ciliatus under that name, did 

 not seem to be aware that Martens and Galeotti's Allosorus chtprophyllus 

 was identical with it, for he separates it from Allosorus, with the remark 

 " indusia spuria lobulata et saepius interrupta ad Cheilanthem sine dubio 

 delegant." He was familiar with the Mexican and Peruvian plants, yet 

 places them in two different genera. Humboldt's name is very character- 

 istic. Link's H. rufescens is appropriate to some states of this plant, which 

 is very variable in colour. There seems no reason why Presl should change 

 Humboldt's specific name to " citiata," unobjectionable as the latter may 

 be in allusion to the generally ciliated edge of the involucres, well repre- 

 sented by Humboldt, but omitted by Martens and Galeoiti. The broad 

 involucres, when continuous on each margin, almost meeting at the back, 

 resemble those of Cryptograrnma crispa, Br. 



{Involucres continuous. Pteridoideae).
