viria, ;i trade name for packages containing a mixture 

 of many kinds; viol^cea-striata, violet-purple. Tht-re 

 are several double forms of /. purpurea. Var. £1. pi. 

 has very large Ivs. : tls. appearing much later tlian siu- 

 ;j;le varieties, semi- or much-doubled, bluisli white 

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

 very floriferous and a good pot-i)!ant. G.F. 5:59.'i. A.ij. 

 14:246. Var. violacea fl. pi., Hort., is entirely distinct 

 from the preceding. (U. 47, ]). VSA. 



4. hederttcea, Jacq. (/. Nil, Koth. /. srilhra, Hort. ). 

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

 (ivate-cordatf , the lobes ovate to ovate-lanceolate, entire, 

 of the lateral lobes repand or denticulate; the mid<lle 

 lobe narro>wed at the bast.-: peduncle l-li-fld., mostly 

 sliorter than the petiole: c.orulla funnelforra, the tube 

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

 ill various combinations of these colors; sepals hairy, 

 lanceolate, with long and often recurved tijis. duly-Oct. 

 — Widely naturalized from trop. Ami'rica in tii'I(is and 

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

 haps native in the. South. B.R.I; 85; 4:276 {as [. cn'riiJen). 

 B.M. 188 (as Convolvnlus Nil). On. 27. p. 47;{. This spe- 

 •■ies shows great variation in the form of its Ivs., both 

 nil the same plant and on ditferent plants. In some 

 forms formerly known as f. 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 

 iippearance of these oriental varieties in occidental gar- 

 <leus, the species had already varied into many distinct 

 horticultural varieties; as var. limb^ta {/. liinh()l<i, 

 Ifort. ), with the corolla vhdet-pnrple, edged with white.

ing named varieties of Japanese Ipomceas are offered: 

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

 Aglaia, Ivs. variegated: fls. crimson, with white throat. 

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

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

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

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



ted with white is shown in I.H. 43, p. 7.". The various 

 strains give fls. which are diversely scalloped, ruMled, 

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

 oring. 



5. Mexicina, Gray. Like /. hedcracea, but young Ivs. 

 entire or slightly angulate, becoming deeply 3-lobed and 



1168. Ipomcca coccinea (> 



eonlate, as in hedtn-acea, the middle lobe broadest ; 

 peduncles as long or longer than petioles: corolla lin. 

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

 I'ossiblj' this should not be distinguished from I. hede- 

 raci'n. The plants in the trade as /. Mexicana are 

 mostly/, hedcyacea , digitata and Uona-nox. I. 3Cexi-

6. angU3tif6Iia, Jacq. (/. fillcauh'.^, P>lume). Stem 

 prostrate, trailing or rarely climliing, 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 distribiited in troiiical Asia, 

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

 ticK lata ).~-Somi'timi's grown in the warmhouse, liut 

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

 eyed flowers. 



7. coccinea, Linn. Stak 1pom(ka. Viu:. lUiS. Stem 

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

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



several-fld.: corolla? 



i in. wide, salverform: limb ol)- 



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

 Apparently naturalized frf)m tropical America, on river 

 hanks in the middle and s<iuth Atlantic states; probably 

 indigenous to northern ^IMex. and Ariz. J-5.M. 221. — Fls. 

 are produced in atmndance, but are disappointingly 

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

 or with a tinge ct' scarlet. 



Var. hederifolia, Gray ( /. hederi folio . Linn. M'ma 

 stnir/KiVfa, Hort.). Fig. 1169. This Plains form of the 

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

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

 p. 159. — It is superior to the type for ornamental ()ur- 

 poses. 



8. rubro-csenilea, Hook. {I. noolceri, Hort.). Stem 

 tinged with purple, liranched, 10-2(1 ft. high: Ivs. mem- 

 branaceous, much-veined, short-acuminate : peduncle 

 fleshr, .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. ]8.i5:441 (as Phnrhids rnhro- 

 aerulen). 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- 

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

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

 early floweriniz:. It makes an excellent pot-plant for the 

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

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

 proves to be a blue form of /. rvhro-cceruha , which is 

 especially valuable for cut-fls. Var. 41ba, Hort., has 

 pure white flowers.
