CATANANCHE (Greek name, referring to ancient 

 custom of using the plant in making love-philters). 

 Composite. Annual or perennial garden herbs, grown 

 for the bloom. 



Leaves crowded at the base of the St., and linear 

 or lanceolate: head long-peduncled, blue or yellow: 

 achene oblong, ribbed and usually villose or setose: 



Eappus of 5-7 lanceolate long-acuminate scales. A 

 alf dozen species in the Medit. region. Of easiest 

 cult, in any garden soil, particularly if light. Prop, by 

 seeds and division. Useful for cutting. 



caerftlea, Linn. Perennial, 2 ft.: Ivs. tomentose, 

 lanceolate and few-toothed, 3-nerved: fl.-heads 2 in. 

 across, with wide flat-toothed blue rays, on long slen- 

 der sts. Blooms in June, July and Aug. S. Eu. B.M. 

 293. R.H. 1890, p. 523. G. 28:541. Gn. 42, p. 25; 55: 

 368. Var. alba, Hort., has white fls. Gn. 55:368. Var. 

 bicolor, Hort., has white margin and blue center. 

 Often used as everlastings. L\ H. B. 



CATASETUM (Greek for downward or backward, 

 and bristle). Orchiddcese. Epiphytic or terrestrial 

 orchids, requiring hothouse conditions. 



Stems short fusiform: Ivs. plaited, membranaceous: 

 scapes basal; fls. in racemes, globose or expanded; 

 labellum fleshy; column erect, provided with sensi- 

 tive appendages which, when touched, cause the pollen- 

 masses to fly out; pollinia 2. The genus includes Mon- 

 achanthus and Myanthus. There are about 50 or 60 

 species in the American tropics. 



The flowers are in racemes or spikes, firm in texture, 

 and white or in shades of green, yellow, brown or purple. 

 Catasetums are not much cultivated, since most of 

 the species are not showy, but they are interesting to 



the botanist and amateur because of the striking ejec- 

 tion of the pollen-masses. Gardeners often have trouble 

 with catasetums, but they are not difficult to grow if 

 given good care. They need a high temperature, long 

 period of rest, and free supply of water during the 

 growing season. They are grown in both pots and bask- 

 ets. Readily propagated by dividing the plants at the 

 base; also from very ripe pseudobulbs cut in pieces and 

 put in sand. For culture, see Orchids.
