C. ssqinSticum, Hildeb. Intermediate between C. grsecum and 

 C. pseudo-grsecum; from the former it differs in its small fls. and 

 other parts and from the latter in having more rounded Ivs. Greece. 

 C. grsecum. Link. Autumn-flowering: Ivs. obcordate, irregularly 

 cartilaginous-dentate: corolla-lobes lanceolate or oblong-lanceo- 

 late, eared at base, rose-colored with deep purple at base. S. E. Eu. 

 C. hiemale, Hildeb. Winter-flowering: Ivs. round-reniform, bright 

 green and silver-zoned: fl. purple with deep red in the throat; 

 corolla-lobes round-ovate, not eared. Asia Minor. C. Jdvis,

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

 bitacese. Annual- or perennial-rooted herbs, one of 

 which is sometimes grown for its ornamental character. 



Climbing by tendrils, glabrous or pubescent: Ivs. 

 entire, lobed or 5-7 -foliolate : fls. monoecious, minute, 

 yellow, greenish or white, with their parts in 6's, 

 stamen 1 with a 1 -celled anther. The plant is a climb- 

 ing half -hardy annual of easy cult. The seed should 

 be started indoors early. The genus is near Echino- 

 cystis and Elaterium, and has more than 30 species, all 

 from Trop. Amer. 



pedata, Schrad. Annual: st. glabrous: Ivs. pedately 

 5-7-foliolate, the Ifts. sessile or nearly so and lanceolate 

 or oblong-lanceolate, serrate: tendrils 3-4-parted: male 

 fls. small, in panicles equaling or exceeding the Ivs.: fr. 

 nearly sessile, somewhat soft-prickly or smooth, oblong 

 and attenuate at base, green becoming yellowish white, 

 2-locular. Mex. south. A strong ornamental climber. 

 C. explodens, Naudin, with somewhat 3-lobed Ivs. and 

 short spiny explosive fr., may be in cult. L. H. B. 



CYCLANTHUS (flowers in a circle) . Cyclanthacese. 

 A Trop. American genus of 4 species giving name to a 

 small order which is allied to the palms. They are 

 acaulescent palm-like herbs with a milky juice: Ivs. 

 long-stalked, entire or bi-furcate, the segms. lanceolate, 

 1 -nerved: fls. fragrant. The species are not in the 

 American trade. Cult, of Carludovica (which see). C. 

 bipartttus, Poit., of Guiana, has Ivs. sometimes divided 

 into 2 long narrow lobes, the petioles being 3-6 ft. 

 long: spadix straight and cylindrical, in a 4-lvd. 

 yellow spathe, the scape 2 ft. long. G.W. 8, p. 153; 15, 

 p. 610. C. cristatus, Klotzsch, of Colombia, has short- 

 stalked bifid Ivs., with the parts falcate and connivent: 

 spadix about 8 in. long. G.W. 8, p. 202. C. discolor, 

 Hort., has young Ivs. streaked with brown-orange: lys. 

 bifid, the parts lanceolate, acuminate, the margins 

 frilled. Probably S. Amer. C. Godseffianus, Hort., 

 exhibited in 1892, "has noble Ivs. of a rich green color, 

 oblong, obovate, tapering to a sheathing stalk." 

 Sander. 



CYCLOB6THRA: Calochortus. 



CYCLOLOMA (Greek for circle and border, from the 

 encircling whig of the calyx). Chenopodidceas. One 

 weedy herb, C. atriplicifdlium, Coulter (C. platyphyl- 

 lum, Moq.), of sandy soils from Minn., west and south, 

 which was once intro. 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 a much-branched rank-growing annual, 1-2 ft. 

 high, pubescent or nearly glabrous, with narrow but 

 flat and sinuate Ivs., and bractless 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 or jointed. 



CYCLOPHORUS (Greek, circle-bearing). Polypodi- 

 acese. An E. Indian and Malaysian genus of simple- 

 Ivd. ferns, related to some species of Polypodium. The 

 genus is characterized by having creeping scaly root- 

 stocks, simple Ivs. usually densely covered with star- 

 shaped scales, at least on the back. The sori are round, 

 naked, and placed so closely together as to appear often 

 completely to cover the back of the If. The venation 

 consists of a very fine close network difficult to dis- 

 tinguish. Often listed in trade under Polypodium. 



Lingua, Desv. (Niphobolus Lingua, Spreng.). Lvs. 6- 

 12 in. long, on short stalks, the If .-blades thick, leathery, 

 narrowly oblong, 4-8 in. long, 1-2 in. broad, densely 

 covered beneath with rusty white scales. Var. corym- 

 bifera, Hort. A form with the tips of the Ivs. much 

 forked, making the blade much broader than in the 

 type. Var. variegata, Hort. A form with "light yellow 

 lines about J^in. wide and %in. apartj running across 

 the fronds at right angles to the midrib." See also 

 Polypodium. R. c. BENEDICT. 



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

 shape of the column). Orchidaceas. Epiphytic orchids, 

 requiring warmhouse treatment when growing. 



Pseudobulbs fusiform: lys. plicate: fls. of 2 sexes, the 

 perianth alike, the lip entire, or that of the staminate 

 very different, with the sepals and petals narrower, the 

 lip clawed and with finger-like projections from the 

 side, the column much elongated and arched; pol- 

 linia 2. Both sexes may be produced in the same plant. 

 A third form of fl., usually perfect, occasionally appears; 

 this is intermediate between the others. About a dozen 

 species of Trop. Amer. 



A. Perianth alike in both sexes; lip entire. 



chlorochilon, Klotzsch. Pseudobulbs 5-7 in. tall: Ivs. 

 lanceolate: raceme erect, 2- or 3-fld.; fls. 4-6 in. across; 

 sepals and petals yellowish green, acute, the lateral 

 sepals broader than the dorsal; lip obovate or elliptic, 

 acute, a dark green depression near the triangular erect 

 callus. Venezuela. G.C. III. 3:145. I.H. 35:65. R. 

 1:39. J.H. III. 35:285. Gn. 49, p. 403; 51:172. 



ventricdsum, Batem. Pseudobulbs 8-10 in. tall: Ivs. 

 lanceolate: raceme drooping. 4-6-fld.; fls. 4-5 in. across; 

 sepals and petals yellowish green, acute, the petals 

 broader than the sepals; lip white, cordate, acuminate, 

 clawed, a black callus at the junction of the claw witn 

 the lip. Guatemala. 



AA. Perianth differing in the sexes; lip with finger-like 

 lateral projections. 



aureum, Lindl. Male racemes pendulous, 8-12-fld.; 

 fls. 2-3 in. across, yellow, red-spotted; sepals and petals 

 similar, the former spreading, the latter reflexed; lip 

 clawed, the dilated middle giving rise to a number of 

 projections, forked at the end. Cent. Amer. J.F. 3:264. 



pentadactylon, Lindl. Male racemes usually pendu- 

 lous, many-fld.; sepals and petals greenish yellow 

 barred with brown; lip white, red-spotted, with 5 

 finger-like projections; female racemes erect, few-fld.; 

 sepals and petals broader than in the male fls., spotted; 

 Up ovate, entire. Brazil. B.R. 29:22. J.H. III. 62: 

 305. O.K. 8:312. 



peruviana, Rolf e. Male racemes pendulous, many-fld. ; 

 sepals and petals light green, copiously brown-spotted ; 

 lip, with its projections, white. Peru. Lind. 7:301. 



C. densifldrum, Rolfe. Male racemes pendulous, many-fld., the 

 fls. greenish with purple blotches; female racemes short, erect, 2-fld., 

 the sepals and petals green, the lip ivory-white. Colombia. O.R. 

 17:204;20:331. B.M. 8268. C. maculatum, Lindl. Male racemes 

 pendulous, the sepals and petals light yellowish green, spotted with
