34' T. Holm — Studies in the Cyperacece. 



in length, dense-flowered, all, especially the lowest, peduncled, 

 erect ; scales (fig. 12) lanceolate, acuminate, sj^reading, blackish 

 purple with hyaline apex and very short and inconspicuous 

 midrib, the scale narrower, but longer than the utricle ; utricle 

 (fig. 13) sessile or minutely stij^itate, spreading, roundish, com- 

 pressed, granulated, two-nerved, sparingly scabrous along the 

 upper margins, dark green with purplish spots especially above, 

 terminated by a short, entire or subemarginate beak ; stigmata 

 2 ; style exserted, but short. 



This species, to a certain extent, has the aspect of some mem- 

 bers of the Aeorastachyce^ C. cryptocarpa for instance, but 

 seems, nevertheless, to be more naturally allied to the Miero- 

 rhynchcE^ and its place may be defined as near C. hyperhorea 

 Drej., but diverging from this by the long and spreading scales. 



Carex variabilis Bailey. 



Rhizome stoloniferous with persisting, light-brown to pur- 

 plish sheaths ; leaves flat, relatively broad; scabrous along the 

 margins, as long as the culm or longer ; culm erect, stiff, tri- 

 angular, scabrous especially below the inflorescence, from 10 

 to 45^"' in height, phyllopodic ; spikes from 3 to 6, contiguous 

 or the lowest one remote, the terminal and uppermost lateral 

 ones staminate, the others pistillate or, sometimes, androgy- 

 nous, erect, sessile or the lowest peduncled ; a pistillate spike is 

 often developed from the axil of one of the basal leaves, borne 

 on a very slender peduncle to the length of 12*^"' in length ; 

 bracts of the inflorescence leaf-like about as long as the inflor- 

 escence or the uppermost ones shorter, but without sheaths ; 

 staminate spike broadly linear ; the pistillate, cylindrical, 

 obtuse, dense-flowered except towards the base (from 2 to S'S^"^ 

 in length) ; scale of staminate flower spatulate oblong and 

 obtuse, light purplish with hyaline apex and midrib ; scale of 

 pistillate flower ovate to elliptical, acute, dark purplish to 

 almost black with green, not excurrent midrib, shorter and 

 narrower than the utricle ; utricle sessile, light green, granu- 

 lated, two-nerved (the marginal), obovate to broadly elliptical, 

 compressed, terminated by a short, entire, purplish or green 

 beak ; stigmata 2. 



var. sciaphila nob. 



Culms from 25 to 42*^" in height, very slender and reclining ; 

 spikes very short and mostly remote, otherwise as the type. 



Carex acutina Bailey. 



Rhizome csespitose with persisting, purplish or brownish 

 sheaths ; leaves quite broad and flat, scabrous along the mar- 

 gins, as long as the culms or longer ; culm erect, stiff, triangu-
