490 FIELD MUSEUM OF NATURAL HISTORY BOTANY, VOL. XIX Plant densely cano-villous throughout; leaves eglandular, palmately 5-lobed, the lobes sinuate, the middle lobe broadest near base; bracts bipinnatisect, the segments divaricate at nearly right angles, numerous; ovary densely villous; fruit about 2.5 cm. in diameter, yellowish. Type in the United States National Herbarium, No. 229,235, collected at San Geronimo, Oaxaca, Mexico, altitude 60 meters, July, 1895, by E. W. Nelson (No. 2762). Duplicate at G. DISTRIBUTION: Oaxaca, southeastern Mexico. MEXICO: Oaxaca: Puerto Angel, Morton & Makrinius 2616 (N). This has a general resemblance to var. arizonica, the principal differences being in the shape of the middle leaf lobe and the absence of teeth at the margin of the leaves. The outline of the foliage is like that of var. hibiscifolia, and the indument like that of var. nigelliflora. In the second collection cited the leaves are less pronouncedly 5-lobed. 301g. Passiflora foetida var. arizonica <strong>Killip</strong>, var. nov. Ubique cano-villosa; folia palmatim 5-lobata, lobis sinuatis vel sublobatis, denticulatis, lobo medio ad basin angusto; bracteae bipinnatisectae, laciniis paucis, divaricatis; ovarium pilosum. Plant densely grayish-villous throughout; leaves palmately 5- lobed, the lobes sinuate or sublobate, denticulate, ciliate, the middle lobe narrowed at base; bracts once pinnatisect, the segments divaricate at nearly right angles, relatively few; ovary pilose; fruit about 3 cm. in diameter, yellowish, pilose. Type in the United States National Herbarium, No. 1,365,002, collected in Fresnal Canyon, Baboquivari Mountains, Arizona, September 26, 1927, by G. J. Harrison (No. 4774). DISTRIBUTION: Southern Arizona and northern Mexico. ARIZONA: Baboquivari Mountains, Peebles 8806 (N); Oilman B78 (N). MEXICO: Los Promontorios, Russell & Souviron 10 (N). The nearest relative of this is the Argentine variety, vitacea, both being characterized by a much deeper lobation of the leaves than in other varieties of P. foetida. 301h. Passiflora foetida var. vitacea Mast, in Mart. Fl. Bras. 13, pt. 1: 583. 1872. Stem hispid-hirsute with yellowish hairs; stipules semi-annular about the stem, cleft into unequal, gland-tipped segments, one of
AMERICAN PASSIFLORACEAE 491 which, much longer than the others is linear and often pinnatifid; leaves hastate or subhastate (middle lobe narrowed toward the base, lobulate or incised, the lateral lobes often lobulate), irregularly serrate or serrulate, hirsute or hispid-hirsute; bracts bipinnatisect or tripinnatisect, about as long as the sepals, the segments glandtipped; ovary and styles villous. TYPE LOCALITY: "Banda oriental" (Uruguay). DISTRIBUTION: Paraguay, Uruguay, and northern Argentina, up to 1,100 meters altitude. URUGUAY: Banda Oriental, St. Hilaire 2529 (P, type). Tacuarembo, Arechavaleta 47 (Gen). Laguna Caluendas, Lorentz 1750 (B, N). PARAGUAY: Valenzuela, Hassler 7132 (B, BM, Bo, Gen, K). Igatini, Hassler 5437 (Bo). Cordillera de Peribebuy, Balansa 2207 (Gen, K). ARGENTINA: Jorgensen 2839 (N). Las Palmas, Jorgensen 2616 (G, N). Tucuman: Famailla, Venturi 1628 (N). Leales, Venturi 745 (N). El Puestito, Burroyacu, Venturi 7504 (F, G, N). Cordoba: Sacanta, Stuckert 9915 (Gen), 14999 (Gen). San Teodoro, Stuckert 14849 (Gen), 14962 (Gen). These specimens show a good deal of variation in the form of the leaves, due to a varying degree of lobation. All are characterized by an indument of long, stiff hairs on the leaves and by the development of one of the segments of the stipules, a condition which led Masters to describe the stipules as linear. In addition to the specimens cited above, some referred to the typical form and to var. nigelliflora may belong here. 301i. Passiflora foetida var. santiagana <strong>Killip</strong>, var. nov. Fig. 1, c. Parum viscosa, caulibus et petiolis cano- vel flavido-hirsutis; folia dense lanuginoso-hirsuta, pilis flavido-brunneis, palmatim 5-lobata, lobis oblongis vel oblongo-spathulatis, medio saepe reducto; bracteae tripinnatisectae; ovarium cano-pilosum. Plant scarcely viscous; stem and petioles hirsute with white or yellowish hairs; leaves up to 3 cm. long, palmately 5-lobed (lower lobes often reduced; lobes oblong or oblong-spatulate, rounded or obtuse at apex), densely lanuginous-hirsute with yellow-brown hairs; bracts about 1.5 cm. long at postanthesis, tripinnatisect; ovary white-pilose; fruit 2 to 2.5 cm. in diameter.
