vjlria, a trade name for paokases containing a mixture 

 of many kinds; violacea- striata, violet-purple. There 

 are several double foriirs of I . purpurea. Var.fl.pl. 

 has very large Ivs.: Hs. appearing much later than sin- 

 gle varieties, semi- or much-doubled, bluish white 

 streaked with light blue or pink. Int. 1892. Said to be 

 very floriferous and a good pot-plant. G. P. 5:593. A.G. 

 14:2-46. Var. violftcea 11. pi., Hort., is entirely distinct 

 from the preceding, (it. 47. p. 133. 



4. hederacea, .laiq. (/. Si!, Roth. /. seitbra, Hort.). 

 Stem twining or climbing, 2-8 ft. : Ivs. 2-5 in. long, 

 ovate-cordate, the lobes ovate to ovate-lanceolate, entire, 

 or the lateral lobes repand or denticulate; the middle 

 lobe narrowed at the base: peduncle 1-3-fld., mostly 

 shorter than the petiole: corolla funnelform, the tube 

 usually white, the limb light blue, purple or rose, and 

 in various combinations of these colors; sepals hairy, 

 lanceolate, with long and often recurved tips. July-Oct. 

 — Widely naturalized from trop. America in fields and 

 waste places, Pa. to Fla. ,west to Neb. and Mex. Per- 

 haps native in the South. B.R.I :85; 4:276 (as/, cceriilea). 

 B.M.IHH {a,s Convoloulus mi). Gn. 27, p. 473. This spe- 

 cies shows great vai'iation in the form of its Ivs., both 

 on the same plant and on different plants. In some 

 forms formerly known as /. Nil, the Ivs. are nearly en- 

 tire; in others they are very deeply lobed. Next to /, 

 purpurea, this is now the most popular Morning-Glory 

 in cultivation, and the introduction of the improved 

 Japanese strains will extend its usefulness. Before the 

 appearance of these oriental varieties in occidental gar- 

 dens, the species had already varied into many distinct 

 horticultural varieties; as var. limbita (/. limbdtn, 

 Hort. ). with th«- corolla violet-purple, edged with white. 

 B.M. 5720 (as Plmrbitis Nil); Gn. 29, p.".32. Var. mar- 

 mor^ta cael6stina, large fls., marbled and striped with 

 light blue; Gt. 44, p, 592. Var. marmorita rdsea, Hs. 

 marbled with rose; Gt.44, p. 76. Var. ioliis marmor^tis, 

 Ivs. marked with yellow, limb of corolla rose color. Var. 

 grandiilbra, large blue fls. Var. Ferrandiina, similar to 

 var. graudiflora. Aside from these strains, the foUow- 



ted with white is shown in I.H. 43, p. 75. The various 

 strains give fls. which are diversely scalloped, ruffled, 

 fringed, doubled, and show a wonderful range of col- 

 oring. 



5. Mexicftna, Gray. Like /. Aederocea, but young Ivs. 

 entire or slightly angulate, becoming deeply 3-lobed and 



1167. Mornine-Glory, Ipomoea purpurea iX %). No. 3. 



ing named varieties of Japanese Ipomoeas are offered : 

 Antigone, Ivs. variegated : fls. blue, with pink throat. 

 Aglaia, Ivs. variegated: fls. crimson, with white thro.at. 

 Aseria, fls. dull copper-red. Ceres, like Aglaia, but fls. 

 edged with white. Euphrosyne, Ivs. variegated : fls. 

 pure white, with pink throat. Princess, fls. spotted 

 with carmine. Gt 47, p. 133. A form with foliage dot- 



U68. Ipomcea coccinea (X K)- No. 7. 



cordate, as in hederacea, the middle lobe broadest : 

 peduncles as long or longer than petioles : corolla 1 in. 

 wide, violet-purple, sometimes with crimson plaits.— 

 Possibly this should not be distinguished from /. hede- 

 racea. The plants in the trade as /. Mexivana are 

 mostly /. hederacea, digitata and Bona-nox. I. Mexi- 

 cana vera, Hort.; I. Mexicana grandiflora alba, Hort., 

 and /. Mexicana grandiflora hybrida, Hort., are/. Sona- 

 nor. or /. grandiflora. 



6. angustifdlia, Jacq. (/. filicaulis, Blume). Stem 

 prostrate, trailing or rarely climbing, much-branched: 

 Ivs. 1-3 in. long, less than 1 in. wide, glabrous: pedun- 

 cles exceeding the petioles, bearing 1-2 small, bell- 

 shaped fls., which are yellowish white with a purple 

 eye. Aug., Sept. Widely distributed in tropical Asia, 

 Africa and America. B.M. 5426. B.R. 4:317 (as /. den- 

 <(CK?nta|. — Sometimes grown in the warmhouse, but 

 there is hardly enough foliage to set off the pretty dark- 

 eyed flowers. 



7. coccinea, Linn. Star Ipomcea. Fig. U68. Stem 

 freely twining for 10 ft. : Ivs. slender-petioled, entire or 

 angulate, acuminate : peduncle 2-6 in. long, few- to 

 several-fld.: corolla J^-73 in. wide, salverform: limb ob- 

 scurely lobed, scarlet with a yellow throat. Aug.- Oct. 

 Apparently naturalized from tropical America, on river 

 banks in the middle and south Atlantic states: probably 

 indigenous to northern Mex. and Ariz. B.M. 221. — Pis. 

 are produced in abundance, but are disappointingly 

 small. In var. Ititea, Hort., the fls. are entirely orange, 

 or with a tinge of scarlet. 



Var. hederiiolia, Gray (/. hederifblia, Linn. iOna 

 sanguinea, Hort.). Fig. 1169. This Plains form of the 

 species has angulate, 3-Iobed or even 3-5-parted Ivs., 

 and fls. usually larger. B.R. 1:9. B.M. 1769. I.H. 41, 

 p. 1.59. — It is superior to the type for ornamental pur- 

 poses. 



8. rubro-csertilea, Hook. (/. Robkeri, Hort.). Stem 

 tinged with purple, branched, 10-20 ft. high: Ivs. mem- 

 branaceous, much-veined, short-acuminate : peduncle 

 fleshy, 3— 4-fld.: fls. 3—4 in. wide, the tube white and limb 

 red before expanding, at length purple or china-blue. 

 Aug.-Oct. Mex. R.H. 1855:441 (as .Pharbitis riibro- 

 cwriilea). B.M. 3297. P.M. 3:99. Gn. 27:493.-One of 

 the most beautiful of annual climbers. The fls. are 

 often dashed, blotched and shaded with rose, or are en- 

 tirely rose. It is likely to run to vine when out-of-doors 

 unless the roots are confined in a box or pot to induce 

 early flowering. It makes an excellent pot-plant for the 

 greenhouse. Var. Heavenly Blue, from Calif., was said 

 to be a cross between /. Leari and /. versicolor, but 

 proves to be a bhie form of /. rubro-cwrnlea, which is 

 especially valuable for cut-fls. Var. ilba, Hort., has 

 pure white flowers.
