BABIANA (said to come from Dutch for baboon, be- 

 cause those animals eat the bulbs). Irid(ice(p. About 

 50 corraous plants of S. Afr. FIs. showy, red orpurplish, 

 in a short spike- like cluster or raceme, tubular at the 

 base, the segments with claws or narrow bases, and the 

 limb erect-spreading : ovary 3-loculed : Ivs. narrow, 

 hairy, plaited, standing edgewise to the stem. Low 

 plants, of easy culture if treated like freesias or hya- 

 cinths. Three or 4 eorms in a 4-in. pot give attractive 

 bloom in March or later. Grown only indoors or under 

 frames in the N. They are showy and useful plants.

 overtopping the spikes : fls. lilac or red, long-tubed, the 

 segments oblong and unequal. B.M. 576.

BACCHAEIS [biikkaris, an ancient Greek n.ime). 

 Compusitw. Grchndsel Tree. Shrubs or herbs : lvs. 

 alternate, usually serrate, deciduous or persistent: heads 

 of fls. small, white or yellowish, dicecious ; involucre with 

 many imbricate scales: akenes with pappus. About 250 

 species in America, mostly in tropical regions. A few 

 species are ciiltivatetl particularly for the snow-white 

 pappus, which gives the fruiting plant a very showy 

 appearance. They grow in almost any well drained soil 

 in a sunny position, and are well adapted for dry and 

 rocky slopes, and valuable for seashore planting. Prop. 

 by seeds or by cuttings under glass.

 Ivs. cuneate, obloug or obovate, coarsely toothed, the up- 

 permost entire, glabrous, 1-2 in. long: fls. in large pani- 

 cles : pappus white, about ^sin. long. Sept. Seacoast, 

 from N. Eng. .southward. Gng. 7: 113. — The hardiest 

 species ; in fruit resembling a shrub with abundant 

 snow-white fls.
