give them a thorough soaking with water about 

 January 1, and raise the temperature again to 65 by 

 night, letting it rise during the day to 75 to 80. 

 Syringe the plants two or three times a day, which will 

 encourage the young growths to start all over the 

 ripened wood. When this takes place, the plant will either 

 have to be repotted or fed liberally with liquid manure 

 and fertilizers, repotting usually resulting in larger 

 panicles of flowers. If feeding is resorted to, a handful 

 of green cow-manure to a watering-pot containing two 

 and a half or three gallons of water is 

 sufficient; and if any of the popular 

 fertilizers are used for a change, a 

 small handful to the same amount of 

 water will answer. Water twice in 



between with clean water. 



Plants for a succession may 



be started when the first are 



beginning to 



show the crim- 

 son at the end 



of the flower, 



and so on until 



the end of July or 



first of August. 



Clerodendrons 



are not subject 



to insect pests if 



kept thoroughly 



syringed during their growing season. 



If this is neglected, the shrubby kinds 



may become affected with brown- 

 scale or mealy-bug, which should be 



immediately treated with the usual 



hydrocyanic gas fumigation. (George 



F. Stewart.)

A. Plant of twining habit. 



1. Thomsonae, Balfour (C. Bdl- 

 fouri, Hort.). Fig. 995. Tall, twining, 

 glabrous evergreen shrub: Ivs. oppo- 

 site, oblong-ovate and acuminate, 

 strongly several-nerved, entire, pet- 

 ioled: fls. in axillary, and terminal 

 forking lax cymes; calyx strongly 

 5-angled, narrowed at the apex, white; 

 corolla-limb light crimson and spread- 

 ing; corolla-tube 1 in. long; stamens 

 %in. long. W. Afr. B.M.5313. RH

G.W 4, p. 439; 8, p. 173; 13, p. 340. F.E. 28:261 A 



warmhouse plant of great merit, and the most popular 



the tender species. Blooms profusely on the young 



S iTn o d v? Ct V m ! Hort " (( Y deUctum a *d C. delicl 

 tor^Hort.). Fl.-clusters very large; calyx pure white 

 or green-tinged; corolla large, rose-magenta. 



2. splendens, Don (Siphondnthus splendens, Hiern) 

 A most excellent stove climber: sts. slender woody,' 

 glabrous, slightly angled: Ivs. opposite, variable, oblong- 

 cordate or elliptic, 4-6 in. long, dark green petiole 

 rather short: fls. in dense many-flowered cymes on 

 leafy growths from the ripened wood of the previous 

 year, bright scarlet passing into bright yellow, an inch 

 or more in diam.; stamens 1 in. long. Trop Af r B R

3. specidsum, Hort. A garden hybrid between C. 

 splendens and C. Thomsonse, intermediate in habit and 

 foliage : the fls. are produced in profusion, are dull red, 

 and are continuously borne throughput the summer 

 months; old calices more or less persistent, and orna- 

 mental pale red after fls. are past. As figured in R. H. 

 1873, 471 and Gn. 1877, 404, this recedes very little 

 from typical C. splendens, according to Baker, but the 

 C. speciosum hybridum of I. H. 1869, t593 is interme- 

 diate between C. splendens and C. Thomsonae. 



AA. Plant of erect or self-sup- 

 porting habit. 



B. Corolla-tube not much if any 

 longer than the large calyx: 

 fls. white or light blush. 

 4. fragrans, Vent. (C. cor- 

 onaria, Hort.? Volkameria 

 fragrans, Vent.). Pubescent, 

 half shrubby, with 

 angled branches, 3- 

 5 ft.: Ivs. broadly 

 ovate, with trun- 

 cate or cordate 

 base, acuminate, 

 coarsely toothed : 

 fls. white or blush, 

 in terminal, corn- 

 pa c t , hydrangea- 

 like corymbs, usu- 

 ally double, deli- 

 ciously scented. China, Japan. 

 B.M. 1834. Very desirable and 

 fragrant plant for the coolhouse. 

 Hardy in S. Lvs. ill-scented. 



5. infortunatum, Gaertn. (C. 

 viscosum, Vent.). Height 5-7 ft., 



Kubescent, with square branches: 

 fs. opposite and stalked, cor- 

 date-ovate, acuminate, entire or 

 toothed, hairy: fls. in a loose 

 villous terminal panicle, white, 

 with a flesh-colored center, flar- 

 ing, the tube projecting beyond 

 the loose, hairy, large, 5-angled 

 calyx. E. Indies. B.M. 1805. 

 Fls. sweet-scented. Greenhouse. 



6. trichotomum, Thunb. (C. 

 serotinum, Carr. Volkameria 

 japonica, Hort., not Thunb.). 

 Fig. 996. Slender but erect, 

 graceful, pubescent sub-shrub, 

 4-10 ft. high or even higher: 

 Ivs. mostly opposite, soft and 

 flaccid, ovate -acuminate, nar- 

 rowed at the base, very closely 

 serrate or entire, hairy: fls. 

 white, with a reddish brown 

 calyx, on forking, slender, red- 

 dish peduncles, the corolla-tube 



sometimes twice as long as the calyx; segms. of 

 calyx turning red and affording pleasing contrast 

 to bright blue frs. Japan. B.M. 6561. Gn. 43:504; 

 51, p. 320; 75, pp. 67, 447. G. 26:492. J.H. III. 

 55:355. F.E. 29:653. R.H. 1867, p. 351 A very 

 handsome, hardy shrub or small tree. In the N. it 

 kills to the ground, but sprouts up if the crown is pro- 

 tected. 



7. Fargesii, Dode (C. trichdtomum var. Fargesii, 

 Hort.). A recent shrub, reported as being hardy in 

 England, rapid-growing: Ivs. dark green or purplish, 

 opposite, petioled, the blade ovate and acute or acumi- 

 nate, strongly veined, abruptly narrowed at the base, 

 entire: fls. in panicles in summer, whitish, fragrant; 

 sepals lance -ovate, becoming reflexed: fr. globular, 



996. Clerodendron trichotomum.
