label of the fragments communicated to Kew Herbarium by Ben- 

 nett is marked, presumably by Kurtz himself " 298. DeTiirckheim: 



Flora guatemalensis. Edit. C. Keck." It is by no means the 

 same Bpecies or collection ?) as Tuerckheim 298 of J. I). Smith's 

 distribution (as P. americana), which is P. costaricensis ('hod. 

 The wings are qoI glabrous, as stated by Bennett, but distinctly 



puberuloUS along COSta and toward apex. 



61. V. DuRANDl Chod. Suffruticulose, erectish, about 3.5 dm. 

 high, sparsely luanched 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- 

 ce< 'us. 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, 

 4-5 cm. 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 crenate. 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 (K). 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. trichoptera Chod. Stems erect, hirsute, slender, 1-2 

 dm. high, simple or sparsely branched, from a persistent base.
