According to Schneider's Book of Choice Perns, all 

 Doodias, except 1). blerhnoides, 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 intermediiite tempera- 

 tures are best. They are excellent for forming an under- 

 growth in cool houses, as they are seldom infested with 

 insects, endure fumigation, and do not care whether their 

 taller neighbors are syringed or not. Schneider recom- 

 mends 3 parts of peat and one of silver sand. Loam 

 does not help, but a little chopped sphagnum does. They 

 are very sensitive to stagnant water, and do not like 

 full exposure to sunlight. Always prop, by spores, but 

 division is possible. 



In the American Florist 12:142, "A. H." writes; "/). 

 aspera and its crested variety are most useful, but they 

 can hardly In- ncdiiiiiicnded as market ferns. They re- 

 quire siniiliir tri;itiii.nt to the Blechnums, and are seen 

 at their In >| in h I inrh pot. The young fronds have a 

 verybrit;lit tint, wliic'h livens up the more somber hue 

 of the older fronds. They lose the brighttint much more 

 quickly when allowed to get too dry. Being of slender 

 growth, care should be taken not to over-pot. They like 

 plenty of leaf -mold and peat in the compost, and good 

 drainage."

DORONICUM (Latinized Arabic name). Compisifce. 

 Leopard's Bane. Hardy herbaceous plants, 1-2 ft. 

 high, with yellow flowers, mostly one on a stem and 2-3 

 in. across, 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 Arnioa,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. Doronl- 

 cums have been strongly recommended for forcing. 

 A. Moot-lvs. not notched at the base, oi'ate. 



plantaglneum, Linn. Glabrous, but woolly at the neck, 

 with long, silky hairs: root-lvs, ovate or oval, wavy- 

 toothed : Ktem-lvs, nearly entire, the lower ones narrowed 

 into a petiole and not eared, the upper ones sessile, ob- 

 long, acuminate. .Sandy woods of Eu. Rhizome tuberous, 

 roundish, or creeping obliquely. Stalk of the root-lvs. 

 about 3 in, long. Typically about 2 ft, high, G.C. III.
