A perennial, with a simple densely leafy stem 1-21 in. long. Leaves 3-13 in. long, 
1-23 lin. broad, linear-lanceolate, acute, glabrous, striate, green, the younger laxly ciliate 
with long white hairs, ascending, becoming deflexed with age. Peduncles 2-7 to a plant, 
25-53 in. long, slender, obtusely 4-angled, glabrous; their basal sheaths 1-11 in. long, 
glabrous, with an oblique ciliate mouth, acute or subulate-pointed. Heads 2-3 lin. diam., 
hemispherical, moncecious, white-villous. Involucral bracts in 3—4 series ; the innermost 
2 lin. long, 2-1 lin. broad, suborbicular or broadly obovate, very obtuse, glabrous, minutely 
ciliate, fuscous, the outer gradually smaller. Flowering bracts 2—1 lin. long, } lin. broad, 
oblong, obtuse, apiculate, fuscous, densely bearded with short white hairs on the apical 
part. Receptacle apparently glabrous, but with the base of the pedicels pilose with long 
hairs. Male flowers: sepals ? lin. long, 3 lin. broad, obovate, obtuse, brown, bearded 
with white hairs at the apex; petals connate into a hyaline, subtruncate, minutely 
3-toothed tube, separated from the sepals by a stipes nearly 3 lin. long, glabrous ; anthers 
white. Female flowers: sepals j-1 lin. long, nearly $3 lin. broad, elliptic or obovate, 
obtuse, fuseous or brownish, densely bearded with short white hairs on the apical part; 
petals 3, free, arising close to the sepals, $ lin. long, 2 lin. broad, oblong, obtuse, light 
fuscous, densely fringed with very long hairs on the margins and borders of the inner 
. face, elabrous on the back; ovary glabrous, trigonous ; style elongated; stigmas linear, 
!2 
bifid to halfway down ; appendages rather thick, papillate at the apex. | 
Kotinga Valley, Me Connell & Quelch, 153. Savannahs generally, McConnell & Quelch, 
300. : 
A very distinct species, bearing a resemblance to P. uncinatus, Gardn., in stem and 
foliage, but with very different flower-heads. It might be placed near P. plantagineus, 
Koern.
