ning two-thirds of way to end, from which numerous veins 

 branch flabellately to edge; segments ovate heart-shaped, set at 

 an angle to costa and somewhat decurrent upon it, obtuse or 

 somewhat acute, edges entire or obscurely toothed ; general out- 

 line of spores bluntly triangular, occasionally round or crescent- 

 shaped ; texture moderately thin but varying somewhat with 

 shade or location. 



In general it can hardly be claimed that our eastern Botry- 

 chia are handsome plants, the exception being fine specimens of 

 var. disscctum; but the species now under consideration will cer- 

 tainly rank among our most beautiful ferns. This variety does 

 not fruit so freely as obliquum proper. Out of ten specimens 

 gathered in 1902 only three were fruited. In some cases the next 

 year's bud has broken out of its sheath and cast away its hairy 

 envelop or covering.

Botrychium obuquum elongatum var. nov. Gilbert & 

 Haberer. This variety is easily recognized by one who has made 

 any study of the Batrychia. It is generally of medium size, has 

 long narrow pinnules with rounded, or barely acute, closely 

 placed segments that are finely serrate as in ternatum proper, the 

 pinnae generally acute. The lowest pair of pinnae are twice 

 pinnate, the lowest segments on the inferior side being much the 

 longest, or one-half the length of the pinnule itself. This is 

 sometimes true also of the second pair of pinnae. The rest of the 

 pinnule is only pinnatifid with rounded segments, as are also the 

 upper pinnae. The effect of this large segment on the lower pin- 

 nule is almost like that of an auricle, except that it is generally 

 fully separated from the rest of the pinnule ; and it renders the 

 variety very easy to be recognized.
