campanulate, U inches broad ; segments of outer corona filiform, very 

 slender, thickened at the apex, the inner similar but stouter and half 

 as long, inflexed: fruit globose, 1| inches in diameter: seeds over 

 2 lines lont^. — Banks of the Rio Dulce, in the Chocon River bottoms, 

 and at base of hills near Yzabal, Guatemala; March and April, 1885. 

 Resembling P. membranacea^ Benth. 



Passiflora (Eudecaloba) Choconiana. Glabrous: leaves 

 broadly subcordate in outline, 2 or 2A inches long by 3 or more 

 broad, o-lobed to below the middle, the lobes oblong-lanceolate, acute 

 or acutish, entire ; petiole with 2 pairs of glands ; stipules semi-orbicu- 

 lar, entire : pedicels solitary, naked, equalling the petioles : flowers 

 purplish, rotate-campanulate, 2 inches broad ; segments of outer 

 corona very slender, 6 lines long, the inner in several series, much 

 shorter, incurved. — Banks of the Chocon River, Guatemala ; March, 

 1885. Still another species was collected by me, in the forest of the 

 Chocon River bottoms, with thin, transversely oblong, and very prettily 

 variegated leaves, but without flowers or fruit. 



Orogenia fusiformis. Resembling 0. linearifoUa nearly, but 

 stouter, with a long fusiform root, and the underground base sheathed 

 with scarious bracts : fruiting peduncle 3 or 4 inches long, and the 

 much larger fruit 2^ lines long. — In Plumas County, California 

 (Mrs, R. M. Austin, 1880), and among sagebrush near Truckee, 

 Nevada County {O. F. Sonne, March to May, 1886). 



Peucedanum circdmdatum. Stems solitary from a deep-seated 

 subglobose or oblong and constricted tuber nearly half an inch thick, 

 glabrous or puberulent, a foot high or less, simple or branched : leaves 

 with broadly dilated bases, ternate-quinate, the segments once or twice 

 pinuatisect ; lobes linear, 1 to 3 or 4 lines long : rays few, unequal, 

 ^ to 2}, inches long in fruit ; involucels of 8 to 10 broadly oblanceo- 

 late bracts, exceeding the flowers, yellowish green, becoming scarious : 

 flowers yellow : fruit oblong-elliptical, 3 or 4 lines long, on short 

 pedicels, with broad solitary vitta3 between the prominent ribs. — 

 Abundant on hillsides in the Wallowa region of eastern Oregon 

 ( IF. G. Cusick, June, 188G). Much resembling P. utriculatum, but 

 with a different root. 



Peucedanum Kingii. (P. graveolens, Watson, Bot. King's Exp, 

 5. 128.) The prior publication of P. grcweolens, Benth. & Hook. 

 Gen. PI. 1. 919 (1867), the Anethum graveolens, Linn., necessitates 

 a change in the specific name of our plant. The synonymy as given 

 in the Bibliographical Index may be extended, for the plant was first 

 collected by Nuttall in the Rocky Mountains, and named by him on
