According to Schneider's Book of Choice Perns, all 

 Doodias, except />. bleehnoides, are of dwarf habit, and 

 are useful for fern-cases and for edgings of window 

 boxes, especially for northern aspects, where flowering 

 plants do not prosper. Cool and intermediate tempera- 

 tures are best. They iire i-xi-i-Ilent for forming an under-

 hi^'h. with vlIIcu- tluwurs, mostly one on a stem and 2-3 

 in. acru.ss, borne- high above the basal crown of foliage, 

 from April to June. Prom 10-24 species, natives of 

 Europe and temperate Asia. Stems little branched or 

 not at all : lvs. alternate, radical ones long-stalked, stem- 

 Ivs. distant, often clasping the stem. The genus is al- 

 lied to Arnica.and distinguished by the alternate lvs. and 

 by the style. The plants are of easy culture in rich loam. 

 The flowers are numerous and good for cutting. Doroiii- 

 cums have been strongly rfc-ummended for forcing.
