v&ria, a trade name for packages containing a mixture 

 of many kinds; violicea-stri&ta, violet-purple. There 

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

 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. 

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

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



4. hederilcea, Jacq. (/. 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

 forms formerly kuowu as I. jVil, the Ivs. are nearly en- 

 tire; in other.s 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 m occidental gar

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 fl.s. 

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

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

 with carmine. Gt 4i, p. 133. A form with foliage dot- 



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.

cordate, as in hederacea, the middle lobe broadest : 

 peduncles as longer 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 /. M,.rieana are 

 mostly/ hederarea, cligitata and Jj'oiik-iiox. I.Mexi-

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

 prostrate trailing or rarely climbing, much-branched: 

 Ivs 1-3 m 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. 542G. B.R. 4:317 (as /. den-

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



7 coccmea, Tjinn. Star Ipomcea. Fig. IIGS. Stem 

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

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

 several fld corolla K-% in. wide, salverform: limb ob- 

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

 Apparently naturalized from tropical America, on river 

 banks m the middle and south Atlantic states ; probably 

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

 ire produced in abundance, but are disappointingly 

 smill In var. Wtea, Hort., the fls. are entirely orange, 

 or with a tinge of scarlet.

 sa)i(iuiiua Hort.). Fig. 1169. This Plains form of the

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

 poses 



8 rubro oaertilea, Hook. (I. Hodkeri, Hort.). Stem 

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

 brinacpous much-veined, short-acuminate : peduncle 

 fleshj . .1-i-fld. : fls. 3-4 in. wide, the tube white and limb 

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

 ca-rulea). 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 conflned 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 blue form of /. rubro-ccerulea, which is 

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

 pure white flowers.
