522 FIELD MUSEUM OF NATURAL HISTORY BOTANY, VOL. XIX Section 2. Cirrhipes 310. Passiflora cirrhipes <strong>Killip</strong>, sp. nov. Scandens, suffrutescens, ubique ovario excepto glaberrima; folia ovata vel oblongo-ovata, acuminata, membranacea, costa ad basin biglandulosa; pedunculi tenues, dichotomi, cirrhiferi; bracteae setaceae, caducae; calycis tubus cylindrico-campanulatus, sepalis lineari-oblongis, petalis spathulatis; coronae filamenta 3-seriata, extima subdolabriformia, intima filiformia, inaequalia; operculum erectum, usque ad medium fimbriatum; ovarium ovoideum, rufotomentosum. Woody vine, glabrous throughout except the ovary; stipules subulate, 2 mm. long, coriaceous, soon deciduous; petioles slender, 1 to 1.5 cm. long; leaves ovate or oblong-ovate, 5 to 9 cm. long, 4 to 5.5 cm. wide, sharply acuminate, rounded at base, membranous, entire, penninerved, the lateral nerves 6 to 8 to a side, midnerve biglandular at base, the glands scarlike, oblong, about 1 mm. long, sometimes extending onto the petiole; peduncles slender, bifurcate (common portion and the branches subequal, each 1.5 to 2.5 cm. long), terminating in a reduced or a well developed tendril; bracts setaceous, about 0.5 mm. long, soon deciduous; calyx tube cylindric-campanulate, 7 to 9 mm. long, 4 to 5 mm. wide at throat, conspicuously nerved; sepals linear-oblong, about 1.5 cm. long and 4 mm. wide, subobtuse, yellowish green without, white within; petals spatulate, subequaling the sepals, obtuse, very thin, white; corona filaments in 3 series, erect, the outermost subdolabriform, 9 to 10 mm. long, laterally compressed, short-acuminate above the dilated part, yellow, the filaments of the 2 inner series filiform, unequal, 1 to 3 mm. long; operculum membranous, erect, 2.5 to 3 mm. high, fimbriate about halfway; ovary ovoid, truncate at apex, rufo-tomentose; styles slender, about 6 mm. long. Type in the United States National Herbarium, No. 1,458,328, collected at Zepelacio, near Moyobamba, Department of San Martin, Peru, altitude 1,100 to 1,600 meters, October, 1934, by Guillermo Klug (No. 3883}. Duplicates widely distributed. This species appears to represent a monotypic section in the subgenus Astrophea. The dichotomous peduncles are characteristic of the section Euastrophea, but the species of that group are trees or shrubs, wholly devoid of tendrils, or, in the case of one or two species, cirrhiferous only in the axils of the uppermost leaves. Passiflora cirrhipes is a woody vine and the tendrils terminate the peduncles, in
AMERICAN PASSIFLORACEAE 523 which respect it resembles the subgenera Tryphostemmatoides, Deidamioides, and Polyanthea. Section 3. Euastrophea 311. Passiflora macrophylla Spruce ex Mast. Journ. Linn. Soc. 20: 31. 1883. Tree, 3 to 4 meters high, without tendrils; petioles up to 3.5 cm. long; leaves ovate-lanceolate or oblong-ovate, 30 to 75 cm. long, 10 to 25 cm. wide, or larger, acuminate, rounded at base, glabrous, the midrib biglandular at base; peduncles once or twice dichotomous, 8 to 10 cm. long including the branches; flowers white without, yellow within(?); calyx tube cylindric, 1.2 to 1.8 cm. long, 4 to 5 mm. in diameter; sepals oblong, 2 to 2.5 cm. long, 3 to 5 mm. wide, obtuse; petals oblong, subequal to the sepals; corona filaments in 2 series, the outer slender, liguliform, not dilated, slightly shorter than the petals, the inner falciform, flat, 1 to 3 mm. long; operculum arising near base of tube, membranous, erect, short-filamentose; gynophore slender, 3 cm. long; ovary ovoid, finely tomentulous. , TYPE LOCALITY: Near Mt. Chimborazo, Ecuador. DISTRIBUTION: Western Ecuador; also in western Colombia. COLOMBIA: Antioquia: Kalbreyer in 1879 (K). and Nare, Kalbreyer 1453a (B). Between Medellin ECUADOR: Manabi: Peripa, Rio Daule, 200 meters, Andre 4227 (K, ?Y, excluding flowers). Chimborazo: Base of Mt. Chimborazo, 900 meters, Spruce 6144 (K). Rio San Antonio, near Mt. Chimborazo, Spruce 6203 (BM, type, V). "PERU," but probably Ecuador: Ruiz & Pavdn (Bo, K, Ma). Passiflora macrophylla apparently is separated from the other species of this immediate relationship by the slender, liguliform threads of the outer corona. The leaves attain a greater size than in any other species of the group, except P. gigantifolia, and the calyx tube is more elongate than in most other species of Euastrophea. At the original place of publication of this species Masters cites three specimens, Spruce 6144 ("In Peruvia?"), Spruce 6203, and Andre 4227, and makes the following comment: "In the Flora Brasiliensis I have treated this as a form of P. arborea. M. Andrews specimens, however, having afforded ample means of examining the flowers, I am disposed to consider the present, as Spruce did, a distinct species, and to adopt the characteristic name indicated by that traveller." The locality given for Spruce 6144 in Flora Brasiliensis
