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

 spurred below the tip; Up H4 in. long, swollen, white

long; 



lateral sepals ovate and acuminate, much shorter than 

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

 reflexed mucro; spur Ifl 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.,

 1908:180. A.F. 29:15.5. Gng. 16:3.— An exccUent 

 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, 

 glabvous: lvs. elliptical or lanceolate and narrowed into 

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

 ones almost whorled: peduncles axillary; fls. rich scarlet 

 in the original form; petals flat; standard obovate- 

 orbicular and refuse; 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.

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

 petual flowering variety with purple-carmine fls. 

 marked brilliant ro.se. — /. Sultani was named by Hooker 

 "in honor of that distinguished potentate, the Sultan 

 of Zanzibar, to whose enUghtened and philanthropic 

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



8. HSlstii, Engler & Warb. Very Uke /. 

 Sultani. Fleshy herb or subshrub, nearly 

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

 lvs. 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, 1^4 in. across, flat; 

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

 slender, IJ^ in. long; standard broadly ob- 

 cordate; lateral petals deeply divided into 2 

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

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

 J.H. III. 51:65. R.H. 1906:1.36. G.W. 15, 

 p. 356 (as var. 7tana amabilis). — Of better 

 constitution under cult, than /. 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 jjlants 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; 

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



9. Petersiana, Rehd. Very Uke /. //oZs/u, but all the 

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

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

 peduncles and pedicels longer, fls. carmine-red rather 

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