var. Degeneri R. Krauss. a, b, Degener 8253 ■ 
purpurei-maculosis, nervosis 5-8 gracilibus 
basis ad apicos extendentibus breve stipitatis 
apicibus rostrorum integris aut breve biden- 
tatis oribus glabris aut setaciferis. 
Vegetative ly showing the same characters 
as the species but different in the following: 
pistillate bracts purple-black to black, smooth 
or white fringed on the margins, white-keeled 
through the center, prolonged in some to a 
setaceous awn; perigynia 1-2 mm. long, 3-5 
mm. wide, narrow, oval to elliptic in out- 
line, thinly bi-convex, surface yellow-brown 
splotched with purple, short stipitate, rostrum 
with an entire or weakly bidentate apex 
smooth or setaceous at the mouth, 5-8 thin 
nerves extending from base to the apex. 
Type: Forbes 1189. M, Bog at Waiana- 
panapa, Maui, Aug. 23, 1919- 
Specimens examined 
maui: Degener 8253, Mauka of Olinda 
on the way to Haleakala, June 15, 1927; 
Forbes 1189. M, Bog at Waianapanapa, Aug. 
23, 1919; Forbes 1226. M, Waianapanapa, 
Aug. 23, 1919; F os berg 10026 , between Na- 
kalalua and summit of Puu Kukui, 1740 m., 
Aug. 24, 1933. 
This variety has a distinctly veined surface 
of the perigynium and an entire or slightly 
bidentate rostrum. There is a suggestion of 
the characteristic structure of the variety in 
certain other of the Maui specimens, espe- 
cially those collected near Paliku, Maui, in- 
dicating a degree of transition. Individual 
plants give the impression of different species 
but the presence of intergradations makes a 
higher category impossible.
