70 REPORT ON TWO BOTANICAL COLLECTIONS FROM 
tenuiter obtecta et pilis longis paucis laxe ciliata, subtus vel rare utrinque glabra, 
in axillis dense lanato-villosa. Pedunculi 8-12 poll. longi, laxe villosi, rare glabri. 
Capitula 44-5 lin. diam., albo-villosa. Bracteze involucrantes 3-4-seriatz, late 
ovate, acute, dorso appresse pubescentes, fuscee. Bracteze inter flores oblongse, 
subacute, apice dense albo-barbatz. ^ Receptaculum pilosum. Sepala elliptica, 
obtusa, hyalino-olivacea, ciliata, apice dense albo-barbata. Petala floris masculini in 
tubum infundibuliformem stipitatum connata ; floris foeminei libera, sessilia, anguste 
linearia, dense ciliato-barbata. 
. A stemless perennial. Leaves densely rosulate, 1-13 in. long, 1-1} lin. broad, linear, 
tapering to a blunt point, rather abruptly dilated into a broad open sheath at the base, 
rigid, concave and thinly covered with adpressed white jointed.hairs on the face, convex 
and glabrous on the back, rarely glabrous on both sides, veins not prominent, scarcely 
striate, often, but not always, thinly ciliate with a few long hairs, densely villose-woolly with 
long fine hairsintheaxils. Peduncles 1-3 to a plant, 8-12 in. long, slender, obscurely 6-7- 
angular, thinly covered with short spreading hairs or rarely glabrous ; their basal sheaths 
1-13 in. long, with a rigid oblique subacute ciliate mouth, otherwise glabrous. Heads 
41-5 lin. diam., at first hemispherical, afterwards globose, moncecious or rarely unisexual. 
Involueral bracts in 3—4 series, the innermost 12-2 lin. long, 14 lin. broad, broadly ovate, 
acute, fuscous, adpressed-pubescent on the back, ciliate, the outer gradually smaller. 
Flowering-braets 14 lin. long, $ lin. broad, oblong, obtuse or subacute, pale fuscous, 
densely bearded with white hairs on the apical part. Receptacle pilose with long white 
hairs, as are also the pedicels of the flowers. Male flowers pedicellate; sepals 3, 14 lin. 
long, 4 lin. broad, elliptic, obtuse or subacute, fuscous, densely bearded with white hairs 
on the apical part; petals arising 4 lin. above the sepals, all united into a hyaline 
funnel-shaped tube 2 lin. long, truncate, with 3 very minute teeth at the apex, glabrous ; 
stamens shortly exserted, with white anthers; rudimentary pistil represented by 3 
clavate bodies, minutely papillate at the apex. Female flowers shortly pedicellate ; 
sepals 13 lin. long, 3-$ lin. broad, elliptic, subacute, beautifully reticulated with fuscous, 
ciliate from the base and densely bearded on the upper half with long white hairs; 
petals 3, free, arising close to the sepals, 1 lin. long, about + lin. broad, ciliate and 
clothed on both sides with long white hairs; ovary ovoid, trigonous, glabrous, narrowed 
into a style about 3 lin. long, with 3 linear bifid stigmas, and 3 stout appendages, 
papillate at the apex only. 
Summit of Mount Roraima, 8600 ft., WeConnell & Quelch, 96, 659. 
Allied to P. falcatus, Koern., and P. flavescens, Koern. From the former it differs by 
its more rigid, channelled leaves, less woolly heads, and more acute involucral bracts, 
and from P. flavescens, Koern., by the narrower and more acute leaves, which have a 
different pubescence, and the very different flower-heads. It also appears to be near 
P. Schomburgkii, Klotzsch (which I have not seen), but that plant is described as 
having longer and broader leaves, striate, with prominent veins on the upper side, à 
subulate point to the peduncular sheath, much shorter peduncles, and glabrous involucral 
bracts.
