bladeless (or essentially so), consisting of firm tawny or colored 
sheaths 2.5-5 cm. long," ete.! 
On the border of Nowland Lake in Havelock, Digby County, 
Nova Scotia, occurs a plant with technical characters (perianths, 
seeds, etc.) of Juncus 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
