50 Contributions from the Gray Herbarium 
label of the fragments communicated to Kew Herbarium by Ben- 
nett is marked, presumably by Kurtz himself “‘ 298. De Tiirckheim: 
Flora guatemalensis. — Edit. C. Keck.” It is by no means the 
same species (or collection ?) as Tuerckheim 298 of J. D. Smith’s 
distribution (as P. americana), which is P. costaricensis Chod. 
The wings are not glabrous, as stated by Bennett, but distinctly 
puberulous along costa and toward apex. 
61. P. Duranpi Chod. Suffruticulose, erectish, about 3.5 dm. 
high, sparsely branched near base. Stems simple or sparsely 
branched, somewhat zigzag above, slender, densely pubescent with 
incurved short hairs mixed especially toward base of stem with long 
spreading ones. Leaves ovate or ovate-lanceolate (or the lower oval 
and obtuse), acute to acuminate, slightly mucronulate, subcharta- 
ceous, somewhat reticulate (lateral veins 5-6 pairs), rather sparsely 
pubescent both sides with short incurved and long ascending or 
subspreading hairs, 1.7-4.4 cm. long, 9-16 mm. wide, on incurved- 
puberulous petioles 1.5-2 mm. long. Racemes subsparsely flowered, 
4-5cm.long. Flowers apparently ochroleucous. Sepals lanceolate, 
acute, rather densely incurved-puberulous, 2-2.8 mm. long. Wings 
oblong, rounded at apex, sparsely ciliolate, subsparsely appressed- 
puberulous along costa and toward apex, 6 mm. long, 2.5 mm. wide. 
Keel very blunt, 6 mm. long. Upper petals oblong, 4.8 mm. long. 
Capsule elliptic, strongly emarginate, pubescent on sides, 9-10 mm. 
long, 8-9.3 mm. wide. Seed 5.2 mm. long, subsparsely pilose. 
Arillus 3.2 mm. high, somewhat pilose especially at apex, scarious, 
somewhat umbrella-shaped, the ventral edge vertically descending, 
the dorsal straight, erected at an angle of about 45°, the margin sub- 
entire or very indistinctly erenate. — Chod. Bull. Soc. Bot. Belg. 
xxx. 300 (1891); in Dur. & Pitt. Primit. Fl. Costar. i. 203 (1891); 
Monog. ii. 27. t. 14. f. 13-16 (1893). P. Durandi var. crassifolia 
Chod. Bull. Soc. Bot. Belg. xxx. 301 (1891); in Dur. & Pitt. Primit. 
Fl. Costar. i. 204 (1891). — Guatemala: Skinner (KK). — Skinner’s 
plants differ from Chodat’s description (based on Pittier 519, 
657, and 999, and Tonduz 3073, all from Costa Rica) in their more 
pubescent leaves, sparsely ciliolate wings, and larger capsule ciliate 
with rather long hairs, and may prove distinct when compared with 
Chodat’s types. 
- 62. P. rricnoprera Chod. Stems erect, hirsute, slender, 1-2 
dm. high, simple or sparsely branched, from a persistent base.
