terete or flattened, 1 or 2 inches Jong by a line wide, those on the 

 flowering stems shorter and less attenuate, the lower linear and the 

 upper lanceolate : racemes a terminal pair, with frequently one or two 

 short lateral ones, secund, 1 to 3 inches long ; bracts very small, 

 ovate ; pedicels very short : sepals oblong-ovate, acutish, 1-^ lines long ; 

 petals twice longer, yellow, tinged with brown and with a greenish 

 midvein, lanceolate, united a fourth of their length, equalling the erect 

 long-beaked carpels. — At San Quentin, Lower California ( G. R. Orcwtt, 

 May, 1886). Nearly related to G. edulis. 



Cotyledon parviflora, Hemsl., var. (?) squamulosa. Flowers 

 still smaller, the purple petals 1^ lines long: squamuhe large and 

 conspicuous, half the length of the petals, yellow, cuneate-flabellate, 

 thickened on the upper margin. — On cool slopes or in the thin soil of 

 ledges, on the Potrero and Mapula Mountains, twenty miles south 

 of Chihuahua (731 Pringle, October, 1886); distributed as Sedum 

 sqiiamidosum. Roots fascicled-tuberous. The habit is more that of a 

 Sedum than of a Gotyhdon^ and the petals are united scarcely a fourth 

 of their length. 



Passiflora Brighami. Near P. lunata: leaves subcoriaceous, 

 obdeltoid in outline (2| to 3 inches on each side), subcuneate at base 

 with the sides somewhat curved, the upper margin more or less deeply 

 sinused between the acutish angles ; main nerves setosely excurrent ; 

 ocelli usually 2 pairs ; petioles 3 or 4 lines long : peduncles scarcely 

 equalling the petioles, jointed near the summit: flowers campanulate, 

 8 lines long ; petals white ; lobes of the corona linear-clavate, some- 

 what thickened on the margins and angular, 2\ lines long: ovary 

 tomentose ; fruit subglobose, 6 lines long. — Collected by me on the 

 banks of the Chocon River, Guatemala ; March, 1885. I have also 

 photographs of the plant taken by Mr. W. T. Brigham. It is distin- 

 guished from P. lunata, Willd., by the more triangular and cuneate 

 leaves, fewer ocelli, shorter pedicels, tomentose ovary, and smaller 

 fruit. P. Imiata and P. coriacea, Juss., were collected in the same 

 region. 



Passiflora (Granadilla) Guatemalensis. Glabrous: stems 

 subterete : leaves membranous, ovate, peltate, 3-nerved, entire or usu- 

 ally slightly 3-lobed toward the apex, the lobes acute and setosely 

 tipped, rounded at base, 2| to 4 inches long, on eglandular petioles 

 1 to 2 inches long and inserted 3 to 6 lines from the margin ; stipules 

 reniform, setiferously toothed : peduncles shorter than the petioles ; 

 bracts oblong-ovate, an inch long or less, few- toothed near the cordate 

 base, the teeth and acute apex setosely tipped : flowers white, rotate-
