 Molucca Isls. and not from ternate, meaning 3-leafleted. 



1000. Clivia miniata.

 C. alba, Hort., is a white form. More or less double 

 forms have been known for over a century.

 to Fla. and west to Mo. Also India and Burma. 

 Rarely sold by dealers in native plants.

 branches twining: Ivs. trifoliolate, the Ifts. elliptical 

 or oval: fls. racemose, showy, purple, the standard 

 more than 2 in. long. Trop. Amer. B.M. 3165. An

CLIVIA (after a Duchess of Northumberland and 

 member of the Clive family). Syn., Imantophyllum. 

 Amaryllidacese. Tender bulbous plants with handsome 

 evergreen foliage and showy, bright red or red and 

 yellow flowers in large umbels. 



Bulb imperfect, mostly of old If .-bases: perianth 

 funnelform, curved or straight, the segms. much longer 

 than the tube; ovules 5-6 in each cell: fr. a berry, dif- 

 fering in this from the capsular fr. of Nerine. Three 

 species from S. Afr. J. G. Baker, Amaryllidese, p. 61. 



Olivias make excellent house plants, but, like amaryl- 

 lis, are too costly to be very popular. They have the 

 advantage over amaryllis of having attractive foliage 

 all the year round, and are more certain to bloom 

 well. They have thick, fleshy roots, like an agapanthus. 

 All the species are well worth growing, because of 

 their handsome umbels of flowers, produced during the 



spring and early summer months. Clivia miniata is the 

 species most commonly grown. There are several dis- 

 tinct forms of this, with larger and deeper colored 

 flowers. Established plants may be grown in the same 

 pots for several years, if the plants are fed during the 

 growing period with weak liquid manure. In potting, 

 the soil given should be of a lasting nature, not easily 

 soured, nor likely to become sodden. In arranging the 

 drainage, place one large piece, concave side down, 

 over the hole, and around this arrange several smaller 

 pieces. Over these place one or two handfuls of pieces 

 small enough to go through a No. 2 sieve. The best 

 time to pot is after the flowers have been produced. 

 The plants should then be kept for some time in a humid 

 atmosphere to encourage growth, receiving an abun- 

 dance of water after they are well started. After growth 

 has been completed, they will winter safely in an ordi- 

 nary greenhouse temperature (not under 40), if kept 

 rather dry at the root. For propagation, choose old 

 plants which have become crowded in their pots, so 

 that the entire plant can be pulled to pieces. After 

 trimming the roots, put the growths in small pots and 

 keep in heat, to encourage root action. Clivias are 

 well suited for planting permanently in the front part 

 of greenhouse borders. The soil for this purpose should 

 be rich and well firmed about the roots. Withhold 

 water as much as possible during the resting period, 

 or the plants will produce leaves at the expense of the 

 flowers. (G. W. Oliver.) 



A. Fls. erect; perianth broadly funnel-shaped. 

 miniata, Regel (Imantophyllum miniatum, Hook.). 

 Fig. 1000. Lvs. 16-20, in a tuft, sword-shaped, tapering 

 to a point, 1)4 ft. long, 1)4-2 in. broad: fls. 12-20, in 

 an umbel; perianth erect, bright scarlet, with a yellow 

 throat; tube broadly funnel-shaped, longer 'than C. 

 nobilis; segms. about 2 in. long, the inner ones broader 

 than the outer; stamens shorter than the segms.; 

 style not exserted: berries ovoid, bright red, 1 in. long. 

 Natal. B.M. 4783. R.H. 1859, pp. 126-7; 1869:250,

 36:80; 37:102; 40:177. /. cyrtanthiflorum, Van 

 Houtte (F.S. 18:1877), is a hybrid between this species 

 and the next. It has a curved perianth, with the inner 

 segms. of the limb twice as broad as the outer; sta- 

 mens longer than the corolla. R.H. 

 8:259 (desc.). Var. afcrea, Hort. Fls. 

 yellow with a deeper shade at base of 

 the segms. Var. striata, Hort. Lvs. 

 freely variegated. 



AA. Fls. pendulous; perianth narrowly 



funnel-shaped. 



nobilis, Lindl. (Imantophyllum 

 Aitoni, Hook.). Lvs. about 12, strap- 

 shaped, very obtuse, with a roughish 

 edge: fls. 40-60, in an umbel; perianth 

 curved and drooping; tube narrowly 

 funnel-shaped, shorter than in C. 

 miniata; segms. tipped with green, 

 about 1 in. long; stamens as long as 

 the segms.; style exserted. Cape 

 Colony. B.M. 2856. L.B.C.20:1906. 

 Intro, to cult. 1828. /. cyrtanthiflo- 

 rum, Van Houtte (F.S. 18: 1877), said 

 to be a hybrid between this and the 

 above, shows little if any influence of 

 C. miniata. It has the narrow-tubed, 

 pendulous fls. and the greenish tinge 

 of C. nobilis. R.H. 1894, p. 573. 



C. Gdrdenii, Hook. Very much as in C. 

 nobilis but with the corolla-lobes obviously 

 spreading: stamens as long as the perianth- 

 segms. ; anthers oblong, yellow. B.M. 4895. 

 A desirable plant. WlLHELM MlLLER. 100 l.
