CALONYCTION 



CALOTHAMNUS 



I. noctiphyton, I. noctiflora, I. mexicana grandiflora, I. 

 mexicana grandiflora alba, I. mexicana grandiflora vera. 

 These trade names represent strains of varying ex- 

 cellence. (C. grandiflorum, Choisy, is Ipomcea Tuba.) A 

 form with variegated Ivs. is offered. Var. heterophyllum, 

 has Ivs. 3-5-lobed and subhastate. The moonflower 

 is most popular as a garden plant, but it also does 

 well trained along the roof of a low house or against 

 a pillar. It is excellent for cut-fls. in the evening. 

 Little grown in the open N. because it does not 

 mature in the short seasons. It grows wild in swamps 

 and thickets in peninsular Fla., and is probably 

 indigenous there. Widespread in tropics of both 

 hemispheres. 



muricatum, G. Don. (Convdlvulus muricatus, Linn. 

 Ipomoea muricdta, Jacq. Calonyction speciosum var. 

 muricatum, Choisy). Fls. purple, smaller than those of 

 C. speciosum, the 

 tube very slender 

 and the expanded 

 partof the tubenot 

 over 3 in. broad. 

 Tropical regions; 

 extensively cult, 

 in Japan and 

 India, and often 

 seen in American 

 conservatories. 



C. tastense. House 

 (Ipomcea tastense, 

 Brandeg.) , is the third 

 speciesof Calonyction. 

 It is native to Lower 

 Calif., and not in 

 cult. C. grandifldrum,

CALOPHACA 



(Greek, kalos, 

 beautiful, ana 

 phaka, lentil). 

 Leguminbsse. Or- 

 namental plants 

 cultivated chiefly 

 for their bright 

 yellow flowers ap- 

 pearing in sum- 

 mer. 



Deciduous 

 shrubs or herbs, 

 with alternate, 

 odd-pinnate, pub- 

 escent, and often 

 glandular Ivs.: 

 stipules scarious 

 or herabceous, adnate to the petiole: fls. papili- 

 onaceous, solitary or in racemes; calyx tubular with 5 

 nearly equal teeth; standard upright; wings oblong, 

 free, as long as keel; ovary sessile with many ovules: 

 pod pubescent and glandular, cylindrical. About 10 

 species from S. Russia to E. India. 



The two cultivated species are low, prostrate shrubs, 

 with grayish green foliage, and rather large yellow 

 flowers in erect axillary racemes, followed by decorative 

 reddish pods. They prefer a well-drained soil and sunny 

 position, and are well adapted for borders of shrubberies 

 and sandy or rocky slopes. Propagated by seeds sown 

 in spring; the young seedlings should have plenty of 

 light and air, as they are very liable to damp-off if kept 

 too moist and shady. Sometimes grafted high on Cara- 

 gana or Laburnum, forming a very attractive small 

 standard tree with pendulous branches. 



wolgarica, Fisch. Fig. 751. Two to 3 ft.: pubescent 

 and glandular: Ifts. 11-17, roundish-ovate or oval, Yy- 

 3^in. long: racemes long -ped uncled, with 4-7 fls.; 

 corolla over %in. long. June, July. S. Russia, Turkes- 



751. 



Calophaca 

 wolgarica. 



(XH) 



tan. C. grandifldra, Regel, is similar, but Ifts. 17-25: 

 racemes 10-16-fld.; corolla 1 in. long. S. Russia. Gt. 

 35:1231. ALFRED REHDER. 



CALOPHYLLUM (Greek, beautiful-leaved). Guttif- 

 eracese. Woody plants of the Old World and American 

 tropics, with shining leathery leaves, sometimes planted 

 South. 



Leaves parallel- veined at right angles to the midrib: 

 fls. polygamous in many axillary or terminal clusters; 

 sepals and petals 4-12, in 2-3 series; stamens very nu- 

 merous: fr. a drupe with a single erect seed. Sixty 

 species. Closely related to Garcinia, which, however, 

 has only 4-8 sepals. 



In India, several species are of considerable economic 

 importance, especially C. ionophyllum, which is the 

 source of a gum, and the seeds of which contain the 

 well-known domba oil used extensively for lighting 

 purposes. They must be grown in a warmhouse and in 

 a rich well-aerated soil. 



Calaba, Jacq. CALABA TREE. A tree, to 60 ft.: Ivs. 

 variable, dark glossy green, 3-10 in long. : fls. in axillary 

 racemes, white, rarely produced in cult., the petals 

 about 3 lines long: fr. about 1 in. diam. W. Indies, 

 perhaps intro. from the Old World. Timber and oil. 



inophyllum, Linn. A medium-sized tree, with gray 

 smooth bark: Ivs. 4-8 in. long, 3-4 in. wide, shin- 

 ing on both surfaces: racemes in the upper axils, 

 the fls. about %in. diam. and pure white; inner 

 sepals petal-like: fr. about 1 in. diam., yellow, 

 smooth, almost fleshy. Trop. Asia. N. TAYLOR. 



CALOPOGON (Greek, beautiful beard, in allusion 

 to the fringed or bearded lip). Orchidacese. A very 

 attractive native orchid, sometimes planted in bog- 

 gardens and rock-gardens. 



Flowers magenta-crimson, varying to white, in a loose 

 raceme on a naked scape; sepals and petals all distinct 

 and spreading, the lip narrow at base but broader and 

 hairy above; column winged at summit, not attached 

 to other parts; pollinia 2 in each anther cell. One 

 species, in bogs and moist meadows, Newfoundland to 

 Fla. and westward. Cathea is an older name, but, be- 

 cause of its general acceptance, Caloppgon is retained 

 in the "nomina conservanda" of the Vienna code. 



A moist and shaded position and very porous soil 

 are most suitable for this pretty plant, although it may 

 do admirably in a rock-garden only slightly shaded at 

 midday if the plants are watered very freely every day 

 during hot or dry weather. Propagated by offsets, 

 separated from the old tubers, but the old established 

 plants should not be disturbed very often. Collected 

 clumps of many native orchids are offered at very 

 reasonable figures, and these give immediate results, 

 while the small offsets would not be strong enough to 

 flower for several years, and require much attention 

 during the first year, or perhaps longer (J. B. Keller). 



pulchellus, R. Br. (Limoddrum tuberbsum, Linn., in 

 part). Height 12-18 in., from a solid bulb or corm, 

 bearing a single grass-like If. at the base: scape 2-12- 

 fld.; lip bearded with white, yellow, and purple club- 

 shaped hairs; pretty. G.F. 10:505. J.H. III. 35:45.

CALOSCORDUM: Nothoscordum. 



CALOTHAMNUS (Greek, beautiful bush). Myr- 

 tacese. Australian shrubs (more than twenty species) 

 somewhat similar to Callistemon but more graceful in 

 habit; evergreen greenhouse subjects, and hardy out- 

 of-doors in California. 



Leaves long, alternate: fls. showy, usually red, in 

 lateral clusters; stamens united in bundles opposite 

 the petals; anthers erect, attached by the base, oblong 

 or linear; cells parallel, turned inwards, opening by 

 longitudinal slits. For cult., see Callistemon.
