128 CRYPTOGilAMME. 



the case with the Cedar of Lebanon and the Cedar of Himalaya, it is very diffi- 

 cult to remove the inii)ression once made upon the mind, although no tangible 

 character to distinguish them can be detected. 



I shall now consider the ditl'erent variations or forms of our plant, as much as 

 possible under their respective countries, for I allow that the mass of specimens 

 from Europe, Asia, and America, exhibit some slight differences, often not easily 

 defined. 



1. C. cr'ispa. 



a. forma Europaa ; rather slender suljflaccid, pinnules of 

 the sterile fronds of two kinds, subobovate dee})ly cut into 2-5 

 oblong segments, rarely elliptical and pinnatifido-serrated, 

 those of the mature fertile fronds linear-oblong with the mar- 

 gins or involucres more or less recurved, sometimes quite 

 spreading, and then the pinnules are elliptical. — Crypto-

Hab. General throughout Middle and Northern Europe, especially in mountain 

 regions and moist districts, as far north as Lapland and Lake Baikal, Siberia ;t 

 south to the Pyrenees, Spain; Astnrias, Durieu ; Sierra Nevada, Boissier, elev. 

 8-9000 feet; and to Mount Olympus in Asia Minor, Sihthorpe. 



* Pritzel, ' Ic. Bot. Ind. locuplet.,' quotes vol. vi. t. 11, but my copy of this 

 little-known and most ill-assorted work has no title-page, no date, and no tab. 11, 

 and wo figure of this plant. Several of the plates of this volume bear date 1827 ; 

 and this, as far as I can learn, is about the date of the publication of the genus. 



t The authority for the Siberian plant is Ruprecht and Turczaninow, as given 

 in Trautvetter's ' Plantarum Imagines et Descriptioncs Floram Rossicam lllus- 

 trantes,' and Ledebour, in ' Flora Rossica.' This latter author gives four species 

 of Cryptogramme {'^AUosorus") natives of the Russian dominions, and these are 

 divided into three groups: — 1. " Cryptogramme, R. Br.; frondes steriles et fer- 

 tiles dissimiles. Sori secundum totum decursum venularum pinnuLx, cujus marge 

 primum demum cxplanatus." Under this there arc two species, A.foveolatus, Rupr. 

 (A. crispus, Kaulf. Enum. Fil.), from Unulashka and Kadjak, "an idem ae Cryp- 

 togramma acrostichoides, R. Br. V and A. Sitc/iensi.i, Rupr. (Cr. acrostichoides, 

 Bong., from Sitcha). 2. "AUosorus, Bernh. ; frondes steriles et fertiles dissimiles. 

 Sori versus apiccm venularum pinnuhx, cujus margo semper involutus." To this 

 section our atithor refers Pteris crispa, L., stated to he found only in Russian
