lower ones, a cinereous band usually developing near the top in the 

 second year ; the uppermost sheath subtending the fruit, broadly cam- 

 panulate, black, with about ten very broad 6-8-ridged teeth : teeth 

 broad, rigid, erect or incurved, persistent, black, with a narrow white 

 often deciduous border above, abruptly pointed, tipped with a rough 

 black deciduous awn, deeply 3 -grooved the whole length. Fruit-spike 

 on a short stalk about 12 cm. long, apiculate. Coville& Kearney, no. 

 1084, from Hubbard Glacier, Disenchantment Bay, is taken as the 

 type. A. A. Eaton. 



The anatomical characters of this variety are those of variegatum. 

 The vallecular bast traverses the walls to the holes, thus separating the 

 parenchyma, a character said by Milde never to occur, but shown in 

 some specimens from Hungary. By its external characters, it might 

 well be taken for a variety of hyemale, the dark green rigid stems and 

 appressed sheaths, becoming ashen above, being distinctly those of 

 that species ; but the latter has more numerous ridges which, in 

 American specimens, bear no carinal grooves, while these are very 

 evident in the present variety, and the teeth of hyemale are thin and 

 evanescent, usually twisted together at top and articulated with the 

 sheath below so as to become mechanically detached by the growth of 

 the stem and hence coming off like a candle-extinguisher, leaving very 

 blunt sheath-tips behind, while in the present plant the teeth do not 

 disarticulate but are rigid, persistent, and deeply grooved centrally, 

 with a short deciduous awn. From -variegatum it differs in being 

 taller and stouter, and, principally, in the short appressed sheaths and 

 broad black narrow-bordered incurved teeth. The appressed sheaths 

 would place it with the European trachyodon, which differs from 

 variegatum principally in this character. A. A. Eaton.
