CYCLANTHfiEA (Greek, nnOiers in a circle). Ciicwr- 

 bil()re(e. This genus is interesting as a plant with a 

 fruit that ex|. lodes witli 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 pubes<'eiit. with a 

 perennial root: Ivs. entire, lobed or 5-7 fnlicplate : tis. 

 minute, yellow, greenish or white, with tlicir jinrts in 

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

CYCLOLdMA (Greek for circle and bor- 

 >/''i\ from the fucircling wing of the calyx). 

 t 'In n"j"''lii'ir> 'I . One weedy herb [C. pla- 

 /tlpht'illiiiii, ^iuii.) 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). Orchidicect, tribe I'dndew. 

 Swan Orchtd. An interesting genus of deciduous 

 orchids found in tropical America. PsiudubulKs long, 

 fusiform: Ivs. lanceolate, plicate, lal)el!inii <-uiiiinuous 

 with column; column arcuate, terete, flattening out and 

 becoming clavate at the apex; pollinia 2. The flowers 

 are of different sexes. The same plant may produce 

 male and female flowers. One kind of flower may be 

 fra;;rai]t. the other kinil scrntless. Staminate flowers usu- 

 ally sni.-iller tliaii i.jstill.if,. tluwers; ovary of pistillate 

 HoHiTs tliii'kisli. Stiiuiinate flowers more numerous than 

 piviillatc- tliiwi-rs. About a dozen species. Cult, like Cat- 

 asctinii. rjtiirf in pots or baskets. Prop, by dividing the 

 j.s.'iidi' l.nll.s just as growth begins. Very few forms are 

 in i-ulti\-atiiin 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.

 low, drooping ; sepals and petals lanceolate, purple- 

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