numerous and more vivid-colored fls. and said to be 

 more hardy. 



DD. Plants perennial, tatt, scandent. 



2. speciosum, Poepp. & Endl. Half-hardy slender 

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

 parted to the base into 6 obovate-oblong obtuse divis- 

 ions or If ts. : pedi- 

 cels very slender, 

 red, fls. shaped 

 much like those 

 of T. majus, but 

 smaller, vermilion- 

 red, showy, upper 

 cuneate, lower 

 almost quadrate.

3. peltophorum, 

 Benth. (T. Lob- 

 bianum, Veitch). 

 Annual, climbing, 

 hairy all over 

 except the under 

 parts of the Ivs. 

 and the petals: 

 Ivs. very long- 

 stalked, peltate, 

 nearly orbicular, undulate and with points on the 

 margin: fls. large, long-spurred, orange-red, the 2 upper 

 petals large, rotundate, broad and entire, the 3 lower 

 ones small and clawed and coarsely toothed and also 

 fringed on the claws. Colombia. B.M. 4097. F.S. 2:67. 

 P.M. 11:271. Gn.M. 9:16. Var. fimbriatum, Hubb. 

 (T. Lobbianum \&T. fimbriatum, Hort.), has all the petals 

 toothed or fringed. R.H. 1856: 101. Seldom seen in its 

 pure state. Var. hederifdlium, Hubb. (T. Lobbianum 

 var. hederifolium, Hort.), has variegated Ivs. which 

 resemble those of Hedera helix in shape. Var. miniatum, 

 Hubb. (T. Lobbianum var. miniatum, Hort.), is said by 

 some to be a hybrid with bright vermilion fls. Var. 

 Regina, Hubb. (T. Lobbianum var. Regina, Hort.), is a 

 form with bright salmon-red or salmon-orange fls. 

 There is a horticultural strain of more compact growth 

 known as T. Lobbianum compdctum ', this strain occurs in 

 numerous colors. Horticultural color-forms listed under 

 the name T. Lobbianum are atropupureum, dark purple; 

 aiireum, clear golden yellow; fulgens, dark scarlet; 

 Chaixianum, yellow, washed with red. 



DD. Plant glabrous. 



E . Lvs . orbicular-reniform; nerves terminating in mucrons: 

 petals mucronate. 



4. minus, Linn. Fig. 3854. Dwarf annual, not 

 climbing, smaller in all its parts than T. majus: Ivs. 

 orbicular-reniform, apiculate at the ends of the veins: 

 petals narrow and apiculate at the apex, the lower 

 intensely maculate. Peru. B.M. 98. Very likely 

 blended with T. majus by hybridization, in garden 

 forms. T. pinnatum, Andr., is either a monstrosity of 

 this species or more probably a hybrid between T. minus 

 and T. peregrinum, having the Ivs. somewhat peltate, 



TROPJEOLUM

3855. Tropafolum majus ; the common 

 climbing nasturtium. ( X H) 



with obtuse, unequal lobes: fls. pinnate; petals cuneate 

 with the apex dentate. A garden form. Gt. 62, p. 279. 

 The form known as bimaculatum, Hort., has red peti- 

 oles and peduncles and the 2 upper petals bear a dark 

 blood-red blotch. There is also a yellow form known 

 as luteum, Hort. 



EE. Lvs. orbicular; nerves and petals muticous (blunt). 



5. majus, Linn. Fig. 3855. Strong-growing some- 

 what succulent climbing annual: Ivs. peltate, nearly 

 orbicular and undulate-angled: fls. large, mostly in 

 shades of yellow or orange, with straight spur, the 2 

 upper petals entire or undulate (not apiculate), the 3 

 lower ones narrower and fringed on the claws. Peru, 

 Colombia, and Brazil. G. 4: 2. B.M. 23; 3375 (var. 

 atrosanguineum). F.S. 12:1286 (var. airopurpureum 

 nanum). P.M. 1:176 (var. atrosanguineum). G.C. II. 

 11:665. This species has been in cult, in Eu. since 

 1684. It is the foundation of the common climbing nas- 

 turtiums. Some of these garden forms are probably the 

 offspring of hybridization with T. peltophorum. Some 

 of the horticultural color forms are atropurpurevm, dark 

 red ; atropurpureum foliis-aureis, with golden yellow Ivs. ; 

 cocdneum, scarlet and the form of it with golden Ivs. 

 known as cocdneum foliis-aureis; Heinemannii, choco- 

 late; hemisphericum, light yellow; luteum, yellow; Regel- 

 idnum, purple-violet; Scheueridnum, straw-colored, 

 dotted; Scheuerianum cocdneum, scarlet, striped; Schil- 

 lingii, yellow, brown-spotted; Schulzii, scarlet, with dark 

 Ivs. Var. fl6re-pleno, Hort., is a strain with double fls. 

 occurring in different colors. Var. nan^irn, Hort. TOM 

 THUMB NASTURTITIMS. A dwarf strain occurring in 

 numerous color-forms, some of which are atrococdneum, 

 brilliant scarlet; atropurpureum, dark purplish red; 

 atrosanguineum, a deep blood-red; cocdneum, scarlet 

 and also the golden-lvd. form offered as ndnum cocdneum 

 foliis-aureis; caeruleo-roseum, dark rose; luteum, clear 

 yellow; Regelianum, purple-violet.
