a, Ort. (/. clissMa, Pursh, not Willd. /. 

 sinilafa, 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 :-2-tld., 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. Ara'er., and near 

 the coast from Ga. to Tex.— In Tex. it expands only 2-S 

 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. 



10. Lindheimeri, Gray (/. heferopJnjUa, 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 3H in. long, light blue. Rocky soils, W. Tex. to 

 N.Mex.-Var. Lindley Ana, Hort. {f.J.indleydna,HoTt.}, 

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

 fuse bloomer. An improvement on the type, but more 

 tender. 



11. digitita, Linn. (/. panictilAla, R. Br. I. polmAta. 

 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 lX-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 /. Plafensis). B.M. 

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

 tuberous - rooted Ipomceas for the mrdrii or warm- 

 house. In the North it may be ii^.H witii tin.' i-ffect 

 if grown in a tub and trained in an .i.li.i ■■ nt pillar or 

 trellis, the vine being cut off bil'ur. tio-t and tin- tub 

 stored. Further south the tubers maj be iilanteil di- 

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

 nearly all summer. 



Var. inBignis, Hort. (7. iiisigiiis, 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.

 Var. 41ba, Hort., is /. I.riial; .■ Lady Slade Ims pale 

 rose fls.; var. Briggsii ( /. Urujii^ii. llort.i, or Lady 

 Briggfl, 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 I. HorafalUce. This va- 

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

 Var. Thdmpsoni, OT I. Thomxonidna, Hort., is I. ternata. 



13. tem4ta, Jacq. (7. EorstdUice, var. dlha, Hort 7.

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

 parted, the segrment.s elliptic or elliptic-oblong, fleshy, 

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

 wise like 7. JIorsfalJicE^ 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 7. Morsfatlia. 



14. setdsa, Ker. Brazilian Morning-Gi.ory. Plant 

 very vigorous, branching, covered with stiff purplish 

 hairs: lvs. 3-10 in. wide, cordate, angular or3-lobed, the 

 middle lobe abruptly contracted below into a narrow 

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

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

 belongs 7. Sellowii, Penny, and probably Hort., not 

 7. Helloi, Mart., which is a distinct species. 



16. KstuIbBa, Mart. (7. Tex&na, Coulter). Stem 4-10 

 ft. high, subshrubby, branching, smooth or minutely 

 pubescent: lvs. 4-6 in. long, thiekish, 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 L'nited States. — It is known 

 to the trade chiefly as var. Goodwill (7. GooddU, Hort.). 

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

 and is apparently more floriferous and desirable than 

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

 from cuttings. In the South it is hardy if thestem is 

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

 must be brought indoors. Advertised as the "Tree 

 Ipomoea." 



17. leptophylla, Torr. Bush Moon-Flowek. Stem 

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

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

 ally shorter than the lvs.: corolla about 3 in. across, 

 funnelform, rose-pink, deepening to purple in the 

 throat. Aug.-Oct. Dry plains. Neb. and Wyo., south 

 to Tex. and N. Mex.— This species is adapted for very 

 dry places because of its enormous tuberous root- 

 stocks, which often weigh 100 lbs. and extend into the 

 subsoil for 4 ft. It sometimes thrives where no rain 

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

 when in flower. 



18. pandurMa. Man-of-theEarth. Wild Potato- 

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

 20 lbs.) : lvs. 2-4 In. long, long-petioled, usually cordate 

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

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

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

 fiinnelform with pointed lobes, white with a dark pur- 

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

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