IPOMGEA 



9. sinuata, Ort. ('/. disstcta, Pursh, not Willd. /. 

 sinitata, Hort. ) . Stem somewhat woody at base, covered 

 with long yellowish hairs: Ivs. smooth or nearly so, 

 palmately 7-parted, the divisions lanceolate or narrowly 

 oblong, more or less sinuately cut and toothed : pedun- 

 cles 1-2-fld., longer than the petioles: fls. 1-2 in. wide, 

 bell-shaped, white with purple center; calyx as long as 

 the corolla tube. June-Sept. Trop. Amer., and near 

 the coast from Ga. to Tex. In Tex. It expands only 2-3 

 hours at midday, and is there called the "Noon-flower." 

 It may be treated as a coolhouse evergreen, and is worth 

 growing for its delicate foliage alone. In the North the 

 tubers must be wintered in a cellar. 



1169. Ipomoea coccinea, 

 var. hederifolia (X Yz). No. 7. 



10. Lfndheimeri, Gray (J. heterophylla, Torr., not 

 Orteg). Plant finely pubescent, hoary when young : Ivs. 

 deeply 5-cleft or 5-parted, all of the lobes or the 3 in- 

 terior ones ovate to ovate-lanceolate, with a much con- 

 tracted base: peduncle 1-2-fld. : corolla long funnelform, 

 about 3K in. long, light blue. Rocky soils, W. Tex. to 

 N.Mex.-Var. Lindleyana, Hort. (/. Lindleyana, Hort.), 

 has smaller Ivs., lighter colored fls., and is a more pro- 

 fuse bloomer. An improvement on the type, but more 

 tender. 



11. digitata, Linn. (I.paniculdta, R. Br. J. palmata, 

 Hort. , not Forsk. ) . Stem trailing or climbing, 20-40 ft. : 

 Ivs. 3-7 in. wide, 5-7-parted, the segments elliptic, 

 sometimes spatulate, entire: fls. numerous, in a 2- 

 branched cyme ; corolla l%-3 in. wide, broadly bell- 

 shaped, 5-lobed, pinkish purple or pink : seeds with a 

 dense tuft of dirty white wool springing from the apex. 

 July-Sept. Tropics of both hemispheres. R. H. 

 1853:381. B.R. 1:62 and 4:333 (as /. Platensis). B.M. 

 3685 (as /. Platensis). Gng. 2:311. One of the best 

 tuberous - rooted Ipomceas for the garden or warm- 

 house. In the North it may be used with fine effect 

 if grown in a tub and trained to an adjacent pillar or 

 trellis, the vine being cut off before frost and the tub 

 stored. Further south the tubers may be planted di- 

 rectly in the open, and will give a profusion of bloom 

 nearly all summer. 



Var. insignis, Hort. ( J. insignis, Ker.). Lvs. not pal- 

 mately divided, nearly entire or lobed, the under sur- 

 face sometimes purplish. B.M. 1790. B.R. 1:75. There 

 are few plants of var. insignis in cultivation. 



12. Horsfallise, Hook. Fls. many, in a 2-branched 

 cyme; corolla bell-shaped, the limb of 5 broad, rounded 

 lobes, very showy. Cosmopolitan tropics. B.M. 3315. 

 P.M. 3:50. F.S. 16:1647. K.W. 1:29. -Perhaps the most 

 popular Ipomoea for winter-flowering in a warmhouse. 

 If well treated it will climb 20-30 ft., and will bear hun-

dreds of fls. each day in early winter. /. HorsfaUice 

 may also be grown out-of-doors, but it will not come 

 into bloom till late fall unless the roots are cramped. 

 Var. alba, Hort., is J. ternata ; Lady Slade has pale 

 rose fls.; var. Briggsii (I. Briggsii, Hort.), or Lady 

 Briggs, is generally considered better than the type for 

 most purposes. It is a freer grower and bloomer, the 

 fls. are a rich magenta-crimson, and it roots from cut- 

 tings much more readily than /. HorsfaUice. This va- 

 riety makes a fine plant in a 10-tn. pot. G.M. 37:49. 

 Var. Thdmpsoni, or /. Thomsoniana, Hort., is I. ternata. 



13. ternata, Jacq. (/. HorsfaUice, var. dlba, Hort /. 

 HorsfaUice, var. Thomsoniana, Hort. /. Thomsoniana, 

 Mast.). Stem somewhat woody at base: Ivs. usually 3- 

 parted, the segments elliptic or elliptic-oblong, fleshy, 

 smooth: fls. trumpet-shaped, about 2 in. across. Other- 

 wise like /. Horsfallice, of which it is often considered 

 a variety. Probably from W. Indies. G.C. II. 20:817. 

 F. 1884:118. Gn. 35, p. 440. Not considered quite as 

 effective for greenhouse culture as /. Horsfallice. 



14. setdsa, Ker. BRAZILIAN MORNING-GLORY. Plant 

 very vigorous, branching, covered with stiff purplish 

 hairs: Ivs. 3-10 in. wide, cordate, angular or 3-lobed, the 

 middle lobe abruptly contracted below into a narrow 

 neck: peduncles many-fld., longer than the petioles: 

 fls. 2-4 in. wide, salverform, rose-purple. Aug.-Oct. 

 Braz. B.R. 4:335. An excellent free-growing climbe 

 for covering arbors, and especially valuable for makin 

 a dense screen because of its very leafy habit. In th 

 latitude of New York seeds sown in the open will giv 

 flowering plants in late August. It may also be treated 

 as a warmhouse deciduous twiner. Var. Northern Light 

 is said to be a cross with /. Bona-nox. Plant unusually 

 vigorous, often growing 40-50 ft. : fls. lavender-pink. 



15. Bonariensis, Hook. (1. ficifblia, Lindl. I. Perrin- 

 gidna, Dammer. /. Sellowii, Penny). Stem branching, 

 tinged with purple and covered with short stellate hairs : 

 Ivs. deeply cordate, 3-5-lobed, the middle lobe longest: 

 peduncles several-fld., longer than the petioles: fls. 1%- 

 2 in. wide, violet to lilac, the limb spreading into 5 cre- 

 nate lobes. August-October. Trop. America and Africa. 

 B.M. 3665. B.R. 27:13. P.M. 9:25. Gt. 47: 1446. -He 

 belongs I. Sellowii, Penny, and probably Hort., n 

 /. Selloi, Mart., which is a distinct species. 



16. fistuldsa, Mart. (7. Texana, Coulter). Stem 4-1 

 ft. high, subshrubby, branching, smooth or minutely 

 pubescent: Ivs. 4-6 in. long, thickish, entire or nearly 

 so: peduncles 1-2 in. long, mostly shorter than the peti- 

 oles, few-many-fld. : corolla about 3 in. long, bell-shaped, 

 pink-purple. July-Sept. Brazil; now escaped from gar- 

 dens in Mex. and southern United States. It is known 

 to the trade chiefly as var. Goodelli (/. Goodelli, Hort.) 

 This var. has lavender-pink fls., with a darker thro 

 and is apparently more floriferous and desirable th 

 the type. It produces seed sparingly, but is easily roote 

 from cuttings. In the South it is hardy if the stem i 

 cut down and the roots mulched: in the North, the roots 

 must be brought indoors. Advertised as the "Tre 

 Ipomoea." 



17. leptophylla, Torr. BUSH MOON-FLOWER. Stem 

 2-5 ft. high, with many slender, recurving branches: 

 Ivs. 2-4 in. long, entire: peduncle stout, 1-4-fld., usu 

 ally shorter than the Ivs.: corolla about 3 in. across 

 funnelform, rose-pink, deepening to purple in t" 

 throat. Aug.-Oct. Dry pla'ins, Neb. and Wyo., sou 

 to Tex. and N. Mex. This species is adapted for ve 

 dry places because of its enormous tuberous root 

 stocks, which often weigh 100 Ibs. and extend into th 

 subsoil for 4 ft. It sometimes thrives where no rai 

 has fallen for one to three years. The plant is beautiful 

 when in flower. 



18. pandurata. MAN-OF-THE-EARTH. WILD POTATO- 

 VINE. Stem 2-12 ft. long: root very long and large (10- 

 20 Ibs.) : Ivs. 2-4 in. long, long-petioled, usually cordate 

 and entire, occasionally angulate, fiddle-shape or has- 

 tately 3-lobed : peduncles 1-5-fld., commonly a little 

 longer than the petioles : corolla 2-4 in. wide, broadly 

 funnelform with pointed lobes, white with a dark pur- 

 ple throat. May-Sept. Dry soils, Can. to Fla., west to 

 Mich, and Tex. A. G. 12:637. R.H. 1893:574. B.M. 1603 

 (as Convolvulus candicans), 1939, and Gn. 27, p. 373
