from bulb dealers in the fall and flowered under glass 

 in the spring. It is a most vile-smelling plant when in 

 full flower. The plucky artist who drew the accom- 

 panying picture of this arum wrote at the bottom of his 

 drawing, "Air 'em."

 Perhaps 25 to 30 species in tropical America. The plants 

 are grown in a warmhouse along with Alocasias, An-

 cultivation of Calathea apply very well to Heliconia.

HELIOTROPIUM 



HELIOPHILA (Greek, s«)(-Zori»(/). Cntciferw. This 

 genus includes a blue-Howered half-hardy annual, that 

 grows about 3 in. high and is advertised at present only 

 in the very largest catalogues of flower seeds. The 

 genus contains about 61 species of annual and sub- 

 shrubby perennials, natives exclusively of S. Africa. 

 There are no near allies of garden value. The dehis- 

 cent pod is an important character of the genus. Other 

 important generic characters are pods sessile or pedi- 

 celled, 2-celled, 2-valved: seeds in a single row, often 

 winged. The racemes are long and leafless, and the fls. 

 vellow, white, rosv or sky-blue. Latest monograph in 

 English by Sonder in Flora Capensis 1: 35-54 (1859-60). 

 For general culture, see Annuals. 



The plant in the trade is known as If. arabMdes, 

 Sims, which Sonder refers to H. pildsa, Lam., var. in- 

 cisa, Sonder. H. pilosa is a very variable species, with 

 stem C-24 in. high, erect or diffuse, simple or unbranched 

 from the base: lower Ivs. often opposite, the rest alter- 

 nate: fls. normally sky-blue, with a yellow center, but 

 the natural varieties include lilac and yellow. The typi- 

 cal //. ])ilosa has a stem that is rough with spreading 

 hairs : Ivs. hairy, either oblong or linear, entire or some- 

 times lobed near apex, cuueate at base: pods linear, 

 erect or spreading. Var. incisa, Bonders, has Ivs. linear- 

 cuneate, 3-cut at the apex, rarely 5-cut, the lobes linear 

 or acuminate. B.M. 490. ^_ jj. 



{Greek, like the sun) . Compdsita;. About 

 10 species of hardy herbaceous plants, bearing numer- 

 ous yellow fls. in autumn, and all native to N. America. 

 They are all perennials except one, and that is not culti- 

 vated. They are not common in gardens because of the 

 more attractive forms in Helianthus. H. Icrvis, var. 

 Pitcheritnui, however, deserves wider popularity. Heli- 

 opsis has no pappus, while in Helianthus the pappus 

 has 2 awns. In Heliopsis the rays have pistils, but may 

 be fertile or sterile. In Helianthus the rays have no 

 pistils at all. Stem erect, loosely branching: heads 

 yellow, long-stalked, borne in loose terminal or axillary 

 panii-lc«: Ivs. opposite, petioled, 3-ribbed, oblong-ovate 

 . coarsely toothed. For culture, see

HELIOTROPE. See neliotrophim. 



HELIOTROPIUM (heliotropic ; turning to the sun) . 

 lioruijiuf'H'i If. A widely spread genus in warm regions, 

 of more than 100 species. Herbs or rarely shrubs, with 

 small flowers in terminal, forking clusters and alter-
