LUNDELL: THE GENUS PARATHESIS 127 
Shrub, branchlets slender, ferruginous-tomentose mostly with stellate sessile 
or short stipitate hairs; leaves with tomentose petioles up to 1 em. long; leaf 
blades oblanceolate, 7-14 cm. long, 2-3.7 em. wide, apex subacuminate, the 
acumen obtuse, base acute, membranaceous or subchartaceous, entire or ob- 
scurely crenulate, pilose above at first, the hairs rather sparse, pubescent be- 
neath with red mostly stellate sessile or short stipitate hairs, densest along costa 
and lateral veins, the rays erect or spreading, the costa and primary lateral veins 
slightly impressed above, slender but rather conspicuous beneath; inflorescences 
axillary, few-flowered, paniculate, 1-branched, 2.5—6 cm. long, very slender, weak, 
densely ferruginous-pubescent with mostly stellate hairs; fruiting pedicels 
slender, 7-12 mm. long; sepals triangular, about 2 mm. long, acuminate, pubes- 
cent; fruits ovoid-globose, drying red and up to 8 mm. in diam., persistently and 
and densely pubescent over entire surface; the persistent style pubescent at base.

Lat. 17°26’, Long. 95°49’, alt. 1100 m., May 11, 1939, Richard Evans Schultes & Blas Pablo 
Reko 862 (MICH, type; F, LL, isotypes), tall shrub. 
Well-marked by its reduced inflorescences, obtusely acuminate oblanceolate 
leaves pilose on upper surface, and fruits persistently pubescent, the species 
is akin to P. pleurobotryosa Donn. Sm. and P. vestita Lundell of Guatemala. It 
is the only species of Parathesis known to have pubescent fruits.

Branchlets thick, densely villous with coarse ferruginous stellate stipitate 
hairs; leaves with marginate petioles 1-1.5 em. long; leaf blades lanceolate or 
lanceolate-elliptic, 7-13.5 em. long, 2.5-4.5 cm. wide, apex acuminate, base 
acutish and decurrent, rather obscurely crenulate, subchartaceous, at first 
sparsely hirtellous on upper surface, persistently pubescent on lower surface 
with red stipitate short-rayed stellate hairs, the costa villous and elevated be- 
neath, nearly plane above, the primary lateral veins 12-15 on each side, rather 
conspicuous beneath, slightly impressed above; inflorescences axillary, villous- 
tomentose with coarse red hairs, the hairs of secondary branches shorter and 
less dense, panicles 1- or 2-branched, 5-15 cm. long, long-pedunculate; pedicels 
slender, 5-12 mm. long, villous-hirtellous ; flowers umbellate, papillose-tomentose, 
about 5 mm. long at anthesis; sepals lanceolate-triangular, 1.2-1.8 mm. long, 
acuminate or cuspidate, punctate, papillose-hirtellous ; petals lanceolate, 5.5- 
6.5 mm. long, punctate in lines, papillose-tomentose on inner surface along 
edges and above middle, glabrous below; stamens about 3 mm. long; filaments 
thick, glabrous, 1.2-1.4 mm. long; anthers ovate, 1.6-2 mm. long, thick, dorsi- 
fixed about one-third above base, apiculate, sparingly black-punctate dorsally, 
the area grooved and narrowly triangular, sometimes apically barbate dorsally, 
the basal lobes rounded; ovary ovoid, glabrous below, short villous-hirtellous
