varia, a trade name for packages containing a mixture 

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

 are several double forms of I. purpurea. Var. fl. pi. 

 has very large Ivs. : fls. 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.F. 5:593. A.G. 

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

 from the preceding. Gt. 47, p. 133. 



4. hederacea, Jacq. (7. Nil, Roth. /. scdbra, 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.l:85; 4:276 (as I.ccerulea). 

 B.M. 188 (as Convolmilus Nil). Gn. 27, p. 473. This spe- 

 cies shows great variation in the form of its Ivs., both 

 on the same plant and on different plants. In some 

 forms formerly known as 7. Nil, the Ivs. are nearly en- 

 tire; in others they are very deeply lobed. Next to 7. 

 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. limbata (/. limbata, 

 Hort.). with the corolla violet-purple, edged with white. 

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

 morata coelestina, large fls., marbled and striped with 

 light blue; Gt. 44, p. 592. Var. marmorata rosea, fls. 

 marbled with rose; Gt. 44, p. 76. Var. foliis marmoratis, 

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

 grandifldra, large blue fls. Var. Ferrandiana, similar to 

 var. grandiflora. Aside from these strains, the follow- 



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. Mexicana, Gray. Like /. hederacea, but young Ivs. 

 entire or slightly angulate, becoming deeply 3-lobed and 



1167. Morning-Glory, Ipomcea purpurea (X %). No. 3. 



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. 

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

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



1168. Ipomcea coccinea (X%). 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 7. hede- 

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

 mostly 7. hederacea, digitata and Bona-nox. I. Mexi- 

 cana vera, Hort. ; 7. Mexicana grandiflora alba, Hort., 

 and 7. Mexicana grandiflora hybrida, Hort., are 7. Bona- 

 nox or 7. grandiflora. 



6. angustifdlia, Jacq. (7. filicaulis, Blume). Stem 



R rostrate, trailing or rarely climbing, much -branched: 

 TS. 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 7. den- 

 ticulata). Sometimes grown in the warmhouse, but 

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

 eyed flowers. 



7. coccfnea, Linn. STAB IPOMCEA. Fig. 1168. Stem 

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

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

 several-fid. : corolla %-% 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. Fls. 

 are produced in abundance, but are disappointingly 

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

 or with a tinge of scarlet. 



Var. hederifdlia, Gray (7. hederifdlia, Linn. Mlna 

 sanguinea, 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 pur- 

 poses. 



8. rubro-cserulea, Hook. (7. Hodkeri, 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 PharUtis rubro- 

 ccerulea). 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 I. Leari and 7. versicolor, but 

 proves to be a blue form of 7. rubro-ccerulea, which is 

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

 pure white flowers.
