 R.B. 20:157. Var. grandifldrum, Hort., has larger fls. 

 F.S. 11:1160. I.H. 3:85. 



AA. fls. red or yellow. 



B. Petals small, protruding from the constricted mouth 

 of the calyx. 



2. tricoldrum, Sweet (T. tricolor, Lindl.). Fig. 2583. 

 Perennial from a fleshy or tuberous root, half-hardy, 

 climbing: Ivs. peltate, orbicular, divided into 6 oblong 

 villous leaflets: fls. about 1 in. long, somewhat cornu- 

 copia-shaped, the calyx being the conspicuous part; 

 main part of the calyx vermilion, the short lobes pur- 

 plish, the small petals yellow. Chile. B.M. 3169. B.R. 

 23:1935. F.S. 4:369. P.M. 2:123. -Very choice half- 

 hardy plant and probably the best known in this coun- 

 try of the tuberous-rooted kinds. Usually grown in- 

 doors. Its growth is very delicate. 



3. Jarrattii, Paxt. Much like T. tricolontm, but more 

 robust, the fls. larger, more brilliant in color, the upper 

 part of the calyx with bright spots of yellow, the two 

 upper petals penciled with brown. Chile. P.M. 5:29. 



BB. Petals conspicuous and mostly wide-spreading. 

 c. Spur not as long as the calyx-lobes. 



4. brachyceras. Hook. & Arn. A very slender climber, 

 resembling T. tricolorum in habit: Ivs. peltate, nearly 

 orbicular, deeply parted into 6 or 7 oblong or obovate 

 obtuse lobes: fls. small, on short pedicels, the calyx 

 green and very short-spurred, the corolla with spread- 

 ing yellow petals. Chile. B.M. 3851. B.R. 23:1926. 

 F.S. 4:368. P.M. 4:55. -Half-hardy perennial. 



cc. Spur much longer than calyx-lobes. 

 D. Lvs. parted nearly or quite to the base, or distinctly 



compound. 

 E. Blossoms essentially red. 



5. specidsum, Poepp. & Endl. Half-hardy slender 

 climbing vine: Ivs. peltate at the base, short-petioled, 

 parted to the base into 6 obovate-oblong obtuse divisions 

 or leaflets: pedicels very slender, red, fls. shaped much 

 like those of T. majus, but smaller, vermilion-red, 



showy. Chile. B.M. 4323. F.S. 3:281. P.M. 14:173. 

 Gn. 37, pp. 253, 545. A perennial fleshy-rooted plant, 

 hardy in England. 



3584. Tropaeolum peregrinum the Canary-bird Flower (X %). 



2585. Tropaeolum majus, the common Climbing Nasturtium. 

 (XX.) 



6. pentaphyllum, Lam. Slender climber, the glabrous 

 colored -stems arising from a tuberous root: Ivs. di- 

 vided to the base into 5 oblong or obovate segments or 

 leaflets: fls. small (about 1% in. long), the large red 

 spur being the conspicuous part, the lobes green, and 

 the 2 small petals red. Argentina. B.M. 3190. B.H. 

 22:73. A half-hardy species, showy because of the 

 great number of bright small flowers. 



EE. Blossoms yellow. 



1. polyphyllum, Cav. Perennial, half-hardy: stem 

 succulent, prostrate or climbing: Ivs. peltate, orbicular, 

 cut beyond the center into 7-9 narrow divisions : fls. 

 much like T. majus in shape, but smaller; spur slender 

 but rather short, the calyx -lobes triangular; petals 

 unguiculate, yellow, wavy or emarginate, the 2 upper 

 ones streaked with red. Chile. B.M. 4042. P.M. 10:175. 

 F.S. 20:2066. G.C. II. 20:241. Cm. 45, p. 158. It is a 

 tuberous-rooted species, the stem naturally prostrate. 



8. Leichtlini, Hort. Hybrid of T. polyphyllum and 

 T. edule (see suppl. list), raised by Max Leichtlin, 

 Baden-Baden. Much like T. polyphyllum, but the fls. 

 of brighter color, and the Ivs. larger. 



DD. Lvs. lobed, the divisions usually not extending 

 much, if any, beyond the middle, and the si- 

 nuses usually broad. 



E. Petals fringed. 



9. peregrinum, Linn. (T. CanariSnse, Hort.). CA- 

 NARY-BIRD FLOWER. Fig. 2584. Annual, tall-climbing; 

 glabrous: Ivs. peltate near the margin, cordate-orbicu- 

 lar, divided to about the middle into 5 lobes, which are 

 mostly apiculate: fls. canary -yellow, odd and very ir- 

 regular; spur green, hooked; 2 upper petals erect and 

 large, obovate-clawed, much fringed: 3 lower petals 

 small and narrow and ciliate. Colombia. B.M. 1351. 

 B.R. 9:718. An excellent quick-growing vine, although 

 the fls. can scarcely be called showy.
