BB. Lvs. ovate to lanceolate: probably all perennial. 



c. Peduncles axillary, 1-fld. or sometimes 2-fld. 



D. Spur of fl. much enlarged or swollen at base. 



5. grandiflora, Hemsl. Stout, branching, glabrous: 



Ivs. alternate, stalked, 3-6 in. long, ovate-lanceolate 



and sinuate-crenate, puckered or blistered above 



between the nerves, glandular on lower part of blade 



1952. Impatiens Sultani. 



and on petiole: fls. solitary, to 3 in. across, bright rose- 

 red with crimson stripes on the wing-lobes; sepals 2, 

 green, orbicular-ovate; standard orbicular, erect, short- 

 spurred below the tip; lip 1% in. long, swollen, white 

 netted with purple, abruptly narrowed into an incurved 

 spur 1 in. or more long; wings very large, the terminal 

 lobe obovate and the basal orbicular. Madagascar. 

 B.M. 7826. G.C. III. 29:111. 



6. Oliver!, Wright. Glabrous, reaching 4-8 ft., 

 erect, the sts. pale green : Ivs. 4-8 at a node, oblanceo- 

 late, acute or acuminate, to 8 in. long, dentate-ciliate : 

 fls. 2% in. across, pale lilac or rose-colored, almost 

 white beneath, on 1-fld. peduncles about 2}/2 in. long; 

 lateral sepals ovate and acuminate, much shorter than 

 the petals; lip ovate, funnel-shaped, with abrupt 

 reflexed mucro; spur 1% in. long, curved, slender; 

 standard nearly orbicular, recurved and apiculate at 

 apex; wings deeply 2-lobed, the terminal lobe obovate 

 and the lateral obcordate: fr. oblong. Trop. E. Afr., 

 6,000-8,000 ft. altitude. B.M. 7960. G.C. III. 40:292.

 1908:180. A.F. 29:155. Gng. 16:3. An excellent 

 greenhouse subject and also useful in the open border. 

 It makes a very showy plant when given cool green- 

 house treatment, producing a bush 10 ft. through. 

 Prop, readily either by seeds or cuttings, the former 

 being produced freely. 



DD. Spur very slender throughout. 



7. Sultani, Hook. f. Fig. 1952. From 12-24 in. high, 

 with stout st. and branches, rather succulent and green, 

 glabrous: Ivs. elliptical or lanceolate and narrowed into 

 a petiole about 1 in. long; lower Ivs. alternate, upper 

 ones almost whorled: peduncles axillary; fls. rich scarlet 

 in the original form; petals flat; standard obovate- 

 orbicular and retuse; lip less than half length of petals, 

 suddenly narrowed into a slender upwardly curved 

 long spur. Hybrids and sports have given shades from 

 pink to almost purple, and a white variety also exists. 



Spur is very long and thin. Zanzibar. B.M. 6643.

 I.H. 30:488; 42, p. 140. R.H. 1884 : 12. Increased by 

 seeds; also by cuttings, which root readily. A green- 

 house plant; it also does well as a house plant, bloom- 

 ing almost continuously. Var. Episcopi, Hort. A per^ 

 petual flowering variety with purple-carmine fls. 

 marked brilliant rose. /. Sultani was named by Hooker 

 "in honor of that distinguished potentate, the Sultan 

 of Zanzibar, to whose enlightened and philanthropic 

 rule eastern Africa owes so much." See No. 13. 



8. Hdlstii, Engler & Warb. Very like 7. 

 Sultani. Fleshy herb or subshrub, nearly 

 glabrous, 2-3 ft.: the branches striped red: 

 Ivs. alternate, long-petioled, oval or ovate to 

 lanceolate, acute, crenate and with a bristle 

 between the teeth : fls. 1 or sometimes 2 on the 

 peduncle, pure scarlet, 1% in. across, flat; 

 sepals 3, the lateral small and scale-like ; spur 

 slender, 1J^ in. long; standard broadly ob- 

 cordate; lateral petals deeply divided into 2 

 obovate-spatulate lobes. E. Trop. Afr., 2,500- 

 5,000ft. B.M. 8029. G.C. III. 38:14. Gn. 

 72, p. 337; 74, p. 17. G.M. 48:413; 56:46. 

 J.H. III. 51:65. R.H. 1906:136. G.W. 15, 

 p. 356 (as var. nana amabilis) .^-Oi better 

 constitution under cult, than 7. Sultani, having quicker 

 and more vigorous growth, and larger and brighter fls. 

 It is useful either as a pot-plant indoors or for grow- 

 ing in the open; for the latter purpose, seeds may be 

 started early in spring and plants will bloom from early 

 summer till frost. Var. Liegnitzia, Grign., is a compact 

 condensed form, with color more clear and brilliant 

 than the type, blooming freely throughout the year; 

 excellent for pot cult. R.H. 1909, p. 279. 



9. Petersiana, Rehd. Very like I. Holstii, but all the 

 parts red or bronzy rather than green, sts.pubescent, peti- 

 oles longer: Ivs. longer and elliptic rather than oval, 

 peduncles and pedicels longer, fls. carmine-red rather 

 than scarlet and the petals entire, caps, small and purple. 

 W.Trop. Afr. M.D.G. 1905:390 (descr.) R.H. 1910:452. 



1953. Impatiens flaccida.
