 more nearly circular, long-clawed, the claw inrolled on the margins ; stamens flushed with 

 red, shorter than the calyx ; style shorter than the stamens.

3. Tropaeolum emarginatum Turcz. Bull. Soc. Nat. 

 Mosc. 31 1 : 425. 1858. 

 A glabrous climbing plant. Petioles contorted when young, at length becoming 

 straight ; blades peltate, ovate, 5-lobed, 9-nerved, the lateral lobes a little, the terminal 

 more manifestly, emarginate, mucronate ; peduncles contorted when young, finally becom- 

 ing straight ; spur glabrous, red, more than twice as long as the sepals ; sepals red, gla- 

 brous; petals yellowish, clawed, oblong-obovate, laciniate at the apex, the teeth running 

 out into hairs which exceed the calyx. 



The above is translated and compiled from the original description, as no specimens have been 

 seen ; the species is doubtfully regarded by recent authors. 



Type locality : Near San Bartolo, State of Chiapas, Mexico. 

 Distribution : Known only from the type locality. 



4. Tropaeolum bimaculatum Klotzsch ; Buch. Bot. 

 Jahrb. 15 : 217. 1893. 

 A glabrous highly climbing plant. Stem slender; stipules small, subulate, very thin, 

 deciduous, rarely 2-toothed ; petiole slender, somewhat coiled ; blade subpeltate, reniform- 

 orbicular, 2-2.5 cm. long and 3-4 cm. broad, truncate at the base or nearly so, 5-lobed, the 

 lobes rounded at the apex, distinctly mucronate, the sinuses usually obtuse ; peduncle very 

 slender, somewhat coiled, longer than the leaves ; flowers about 26 mm. long ; spur straight, 

 cylindric-attenuate, 15-18 mm. long ; sepals about 8 mm. long, broadly oblong, very obtuse, 

 occasionally mucronate ; petals 8 mm. long, about as long as the sepals, obovate-cuneate, 

 serrate at the apex with 8-10 teeth, the teeth running out into awns, the lower narrowly, 

 the upper more broadly, clawed ; stamens 5-6 mm. long, shorter than the petals ; style 

 longer than the stamens but scarcely equaling the petals. 



Type locality : Volcano of Chiriqui, Panama. 



Distribution : Known from the type locality and at Cartago, Costa Rica (fide Buchenau).

5. Tropaeolum Warscewiczii Buch. Bot. Jahrb. 26 : 582. 1899. 

 A climbing glabrous plant, not tuberous. Stem angled ; petiole slender, 2-3 cm. long, 

 often curved, rarely coiled ; blade peltate, broader than long, truncate at the base, the 

 upper surface deep-green, the lower glaucous, the margin slightly 5-lobed, the lobes mu- 

 cronate, the sinuses obtuse ; flowers 3.5-4 cm. long ; peduncle very slender, about as long 

 as the petiole, curved, or sometimes coiled ; spur yellow, straight, cylindric-subulate, about 

 22 mm. long; sepals about 5 mm. long, obtuse, ovate, yellow; petals about 7 mm. long, 

 pale-yellow, crenate-ciliate, scarcely exceeding the sepals, the upper orbicular-oval, broadly 

 clawed, ciliate at the apex with about five teeth, the lower oval, more narrowly clawed,
