bladeless (or essentially so), consisting of firm tawny or colored 

 sheaths 2.5-5 cm. long," etc. 1 



On the border of Nowland Lake in Havelock, Digby County, 

 Nova Scotia, occurs a plant with technical characters (perianths, 

 seeds, etc.) of Juricus militaris but differing conspicuously from the 

 typical form of the species in having two well developed cauline 

 leaves, the upper with the sheath much less chartaceous than usual 

 and terminated by a green blade two to four times its length; and in 

 the large accumulation of material in the Gray Herbarium and the 

 herbarium of the New England Botanical Club there are 2 similar 

 specimens from Cape Cod and 1 from southern Connecticut. After 

 finding the Nowland Lake plant with two frondose leaves, Mr. Long 

 and I watched the species carefully, and, although discovering no 

 more of the Nowland Lake form, found that there are occasional 

 colonies with the ordinary submedian erect leaf but quite lacking the 

 firm bladeless sheath above. Sometimes large colonies of this form 

 are uniform, sometimes it occurs with typical J. militaris. 



In the material at hand, 125 collections show the typical form of 

 J. militaris with one long leaf-blade and above it a large colored 

 bladeless or nearly bladeless sheath; 4 collections have two well 

 developed leaves and 21 a single long leaf without the large bladeless 

 sheath above. The latter form, occuring as it does often intermixed 

 with the typical plant, is a minor variation but the other seems to 

 be a well pronounced form and it will facilitate reference to both 

 these extremes if they are designated
