CYCLAMEN 



AA. Spring -blooming species. 

 latifdlium, Sibth. & Sm. (C. Pirsicum, Mill.). Fig. 

 635. The common greenhouse or Persian Cyclamen, in 

 many forms : Ivs. appearing with the fls., ovate, orenate- 

 dentate, usually marbled or variegated with white: fls. 

 on scapes 6-7 in. high, large, scentless, white, purple- 

 blotched at the mouth, but varying into rose-colored, 

 purple and spotted forms, oblong-spatulate in shape, not 

 eared or lobed at the base. 

 Greece to Syria.— C. gi- 

 gantdum, Eort., is the 

 common large -fld., im- 

 proved form of this spe- 

 cies. There are also dou- 

 ble-fld. forms (R. H. 1886, 

 p. 250); also fimbriate or 



CYDONIA 



triangular, dark green above, a little paler below ; 

 slightly 3-lobed ; lobes triangular or ovate-oblong, the 

 middle one acute, the side lobes much shorter, obtuse, 

 acute or almost wanting ; margin of Ivs. with minute, 

 remote teeth : male fls. minute, crowded into few-fld. 

 racemes, which are usually shorter than the petiole; fr. 

 ovate-reniform, obtuse, with a few short spines in the 

 back; seeds small, black, narrowly winged. New Gran- 

 ada. 



CYCIiANTHTTS (flowers in a circle). Oyclanth&cece. 



A small tropical American genus, giving name to a 



small order which is allied to the palms. The species 



are not in the Amer. trade. Culture of Carlu- 



.^ dovica (which see). 



CYCL0B6THEA (name referring to the nec- 

 tariesj . LiliAcece. A small group of west Amer- 

 ican plants, now referred to Calochortus (which 

 see). The fls. are open-campanulate, with naked 

 or only sparsely hairy nectar glands, the sepals 

 more or less pitted. G. fl&va, Lindl. (now known 

 as Calochortus flavus, Schult. ), is in the trade 

 as Yellow Shell-flowek. Stem rather tall, 

 branching, with small, yellow black-dotted 

 fls. : Ivs, narrow-linear. Mex.

 form, and tlie crested va- 

 riety (XK). 



crested forms, C.Pap«io (I.H. 43:63. G.F. 5:235. G.C. 

 III. 21:71; 23:173). G. AUppicum, Fisoh., is a form of 

 it. F.S. 22:2345. Other portraits of G. latifolium are :

Cdiim, Mill. Tuber smaller than in the last : Ivs. with 

 the fls., nearly orbicular, entire, firm, not marbled nor 

 variegated : ils. small, deep red, scentless, half or less 

 as large as those of the last. S'. Eu. B.M. 4. F.S. 22: 

 2345. —There is a white-fld. form ( O. album, Hort. ) . 



IbSricum, Goldie. Dwarf : Ivs. appearing with the 

 fls., ovate-orbicular and rounded at the apex, entire or 

 obscurely undulate, more or less zoned with white 

 above: fls. red, with a purple mouth. Caucasus. — Pet- 

 haps a geographical form of O. Coum. C. Atkinsii, 

 Hort., is a form (perhaps a hybrid) with- larger white 

 fls. F.S. 23:2425. 



0. tiederwTuuain. Hort. (and Ait.?), is C. Neapolitanum.— O. 

 IAban6U(Mm, Hild.,is a new hardy species from Lebanon, with 

 "large, rosy fls., with T-form deep carmine markings at the 

 base of the petals" (see Bot. Jahrb. 25:477).— C repdndum,

CYCLANTHSBA (Greek, anthers in a circle). Cucur- 

 bitdcece. This genus is interesting as a plant with a 

 fruit that explodes with a considerable noise when ripe. 

 The plant is a climbing half-hardy annual of easy cul- 

 ture. The seed should be started indoors early. The 

 genus is near Echinocystis and Elaterium, and has 30 

 or more species, all from tropical America. They are 

 annual, climbing herbs, glabrous or pubescent, with a 

 perennial root ; Ivs. entire, lobed or 5-7 foliolate : fls. 

 minute, yellow, greenish or white, with their parts in 

 6's. Monograph by Coigneaux in DC. Mon. Phan. 3:822 

 (1881). 



ezplftdens, Naud. Stem slender, branched, angled or 

 furrowed, slightly villous, especially at the joints, 0-8 

 ft. long ; Ivs. 2}4-3 in, long, and about as wide, ovate- 



CYCLOLOMA (Greek for circle and bor- 

 der, from the encircling wing of the calyx). 

 Ghenopodictcece. One weedy herb (G. pla- 

 typhi)llum, Moq.) of sandy soils from 

 Minn., west and south, which was once in- 

 troduced as the Cyclone Plant, since the 

 plant is a tumble-weed or rolls before 'the wind when 

 it is matured and becomes detached from the soil. The 

 plant is annual, 1-2 ft. high, pubescent or nearly gla- 

 brous, with narrow, but flat and sinuate Ivs., and bract- 

 less fls. in an open panicle. The fls. are very small, 

 perfect or sometimes lacking the stamens ; calyx 5- 

 cleft, the lobes strongly keeled and becoming winged 

 and inclosing the seed. Plant not fleshy nor jointed. 



CYCNOCHES (swan's neck, from the Greek, referring 

 to the curved column). OrcMddtcece, tribe Vdnde(B. 

 SvPAN Okchid. An interesting genus of deciduous 

 orchids found in tropical America. Pseudobulbs long, 

 fusiform: Ivs. lanceolate, plicate, labellum continuous 

 with column; column arcuate, terete, flattening out and 

 becoming clavate at the apex; poUinia 2. The flowers 

 are of different sexes. The same plant may produce 

 male and female flowers. One kind of flower may be 

 fragrant, the other kind scentless. Staminate flowers usu- 

 ally smaller than pistillate flowers ; ovary of pistillate 

 flowers thickish. Staminate flowers more nuteierous than 

 pistillate flowers. About a dozen species. Cult, like Cat- 

 asetum, either in 'pots or baskets. Prop, by dividing the 

 pseudo-bulbs just as growth begins. Very few forms are 

 in cultivation in America, due to the want of brilliancy 

 in the flowers. Some of the species produce varying 

 flowers on difl'erent racemes on the same plant. 



atireum, Lindl. & Paxt. Fls. numerous, large and yel- 

 low, drooping ; sepals and petals lanceolate, purple- 

 dotted, the petals curved; lip small and much divided, 

 the column purple-dotted. Cent. Amer. 



chlorochilon, Lindl. Racemes about 3-flowered: fls. 

 large, nodding, 5-8 in. across, green; sepals oval-oblong; 

 petals falcate, slightly larger, labellum subsessile rather 

 obovate and concave at base, yellowish green except at 

 the base; column slender, with a wide base, greenish.

pentadActylon, Lindl. Pis. greenish or white, barred 

 or blotched with brown; labellum partly white, spotted
