a sphagnum bog in Quaise, June 1 1 ; the stiff nodulose leaves 

 were unusually broad, even as wide as 6 mm. ; the densely flow- 

 ered spikes were 5-7 mm. thick, with perigynia 4-5 mm. long and 

 2 75 mm. thick, less spreading than in the ordinary form and with 

 more deeply colored, appressed-ascending rather than spread.ng 



scales.

Found only near Reed Pond, a fairly typical form, althoug^ 

 only moderately tufted and not forming the strong, dense tuss( ^_

Lower leaf-sheaths becoming strongly cross-fibrillose ; 

 and culms much greener and rougher-margined than in 

 Goodenovii, the leaves longer and narrower ; spikes more .~~~ 

 and narrower with more numerous, smaller, more acu e, ^ 



or obscurely few-nerved perigynia and narrower, mor 



and much less deeply colored scales. oicnffW 



The plant grew in close association with Carex J^^ 



and the two species seemed to intergrade so perfect y a ^ fi

 Ill-defined and intergrading hybrids between very '& 



species scarcely seem to justify formal designation. ^ ^ 



indeed, as most alleged hybrids are, their occurrence sec^ ^ 

 wholly dependent on chance conditions of unusua propi ^ ^ 

 the supposed parent species. Such intermediate P an terme diates 

 fall into a different category from that of well-defined in^ ^^ 

 of wholly detached existence as, for instance, some ° ^ ^ 



hybrids in Viola which, if they be of hybrid origin, a d
