COSTA RICA.—Atasvureta: Canton San Carlos, Villa Quesada, alt. 825 m., Mar. 10,

Mez in his monograph misinterpreted P. trichogyne, evidently basing his 
description on Guatemalan specimens referable to P. papillosa Lundell, for he 
described the ovary ‘‘apice minute lepidotum.” Hemsley (l.c.) correctly des- 
cribed the species as having ovary ‘‘dense furfuraceo-hirsutum.” 
The type of P. trichogyne has flowers racemose-corymbose and slender pedicels 
up to 7 mm. long. In the type of P. pallida, and the various other collections 
cited in the original description, the flowers are smaller and corymbose, not 
conspicuously racemose-corymbose, and the pedicels are shorter, usually less 
than 4 mm. long. Additional collections are needed to clarify the status of 
P. pallida. 
Types of both P. trichogyne and P. pallida have a bristly tomentose ovary, 
and placentas with 8-14 (19) ovules, uniseriate, partly biseriate or pluriseriate, 
and partially exposed. In Austin Smith P2562 from Costa Rica, there are 16-19 
pluriseriate ovules, the most found in any collection of Parathesis.

Fig. 2 and Plate 1. 
Tree, branchlets stout, closely tomentose with appressed matted hairs; 
leaves large, with long marginate petioles 1-4 cm. long; leaf blades lanceolate, 
oblong-elliptic or oblanceolate, usually 12.5-25 cm. long, sometimes up to 45 
cm. long, 4.5-9 em. wide, sometimes up to 14 em. wide, apex acuminate, or sub- 
abruptly short acuminate, base subacuminate and decurrent, entire but undulate, 
thinly chartaceous, finely pubescent beneath with golden-brown fine closely 
appressed stellate hairs, bizonal, the marginal zone glabrescent early, the mid- 
vein sulcate above, prominently elevated beneath, the lateral veins very slender; 
inflorescences terminal, pyramidal, paniculate, up to 30 cm. long, minutely 
rufous-tomentose, the tomentum consisting of a densely papillose lower layer 
and an upper layer of branched hairs, the glands conspicuous; pedicels up to 
7 mm. long; flowers corymbose, finely rufous-tomentose and papillose, up to 
6 mm. long at anthesis; sepals triangular, spreading, 1-1.4 mm. long, acute or 
acuminate, often almost as wide at base as long, punctate; petals lanceolate, 
about 6 mm. long, black-punctate in lines, papillose-tomentose along edges, 
otherwise glabrous within; stamens up to 4.5 mm. long; filaments slender, black- 
punctate, up to 3.5 mm. long; anthers small, versatile, dorsifixed medially,
