Heliconia contin u 



Heliocarpus continued. 



cuttings will root, during summer, in sand, under a bell 

 glass. 

 H. americanus (American), fl. purple, small, disposed in cymes. 



July. I. cordate, sen-ate, three-lobed, simple, h. 14ft. to 2Jft. 1733. 



HELIOMERIS. A synonym of Gymnolomia (which 

 see). 



HELIOFHILA (from helios, the sun, and phileo, to 

 love; in reference to the plants growing in sunny situa- 

 tions). ORD. Cruciferae. A genus containing (according 

 to Sender) sixty species of annual herbs or sub-shrubs ; 

 but the number is considerably reduced by Bentham 

 and Hooker. All are natives of South Africa. Eacemes 

 elongated. Leaves very variable. Stem round, branched. 

 The annual species are the only sorts grown in our 

 gardens; and these are of easy culture. Seeds should 

 be sown in the open border, during March or April ; or, 

 for an earlier display, in March, in frames, and afterwards 

 planted out. 

 H. amplexloaulis (stem-clasping), fl. varying from white to 



purplish, small. June to September. I., lower ones opposite ; 



upper ones alternate, cordate, stem-clasping, oblong, entire. 



A. 9in. 1774. 

 H. coronopifolia (buckhorn-leaved). fl. blue-violet, spreading. 



June to September. 1. pinnate-parted ; lobes linear, quite entire. 



A. 1ft. to 2ft. 1778. 

 i H. pilosa (hairy). /I. blue. June and July. J. hairy ; lower ones 



lanceolate, pinnatifid ; upper ones linear, quite entire. A. 6m. to 



12m. 1820. (B. M. 2526, under name of H. stncta.) 



FIG. 207. HELICONIA BIHAI. 



H. vlnosa (wine-red). I. large, broadly oblong, lift, long, 

 acuminated, bright green above, purplish beneath ; upper surface 

 transversely plicate or ridged. Stem slender, greenish. Columbia,

HELICTERES (from helMer, a twisted bracelet ; so 

 called from the screw-shaped carpels). ORD. Sterculiacece. 

 A genus comprising about thirty species of pubescent or 

 tomentose, stellate or branched, stove trees or shrubs, dis- 

 tributed over the warmer regions of both hemispheres, 

 the majority being American. Flowers axillary, solitary 

 or fasciculate. Capsules often stellato-tomentose. Leaves 

 entire or serrate. The undermentioned is the species best 

 known to cultivation in this country. Helicteres thrive 

 in a mixture of loam and peat. Propagated by cuttings, 

 taken off at a joint, and inserted in sand, under a glass, 

 in heat. 



EL Isora (Isora). fl. orange-red, axillary. September. I, much 

 resembling, in form and substance, those of the Hazel Nut; 

 when young, tomentose on both sides ; the old leaves lose their 

 pubescence on the upper surface. A. 6ft. India, Australia, <fec. 

 (B. M. 2061.) 



HELINUS (from helinos, a tendril ; in reference to its 

 climbing habit). ORD. Rhamnece. A genus comprising 

 two or three species of climbing shrubs, natives of 

 Abyssinia and South Africa. Flowers umbelled. Leaves 

 alternate, entire, cordate. Branches slender, angular. 

 H. ovatus is a greenhouse shrubby climber; it requires 

 rich, sandy loam, and plenty of pot room. Increased 

 by seeds; and by half-ripened cuttings, placed in sand, 

 in gentle heat. 



H. ovatus (ovate), fl. greenish, in umbels. I. stalked, sub- 

 orbicular, mucronate, feather-nerved. Branches irregular; ten- 

 drils spiral. Natal, 1862. 



HELIOCARFUS (from helios, the sun, and karpos, 

 a fruit ; the valves of the capsule are elegantly ciliated 

 around on all sides). ORD. Tiliacece. A genus com- 

 prising four species of trees or shrubs, inhabiting tropical 

 America. H. americanus, in all probability the only 

 species yet introduced, is a stove evergreen shrub, 

 thriving in sandy loam and fibry peat. Half-ripened 



FIG. 208. HELIOPHILA PILOSA INCISA, showing Habit 

 and detached Single Flower. 



EL p. incisa (incised). I. linear-cuneate, trifid at the point, 

 rarely five-fid ; lobes linear or acuminate. See Fig. 208. (B. M. 

 496, under name of H. arabioides.) 



HELIOPSIS (from helios, the sun, and opsis, like ; 

 in allusion to the appearance of the flowers). ORD. 

 Composites. A genus comprising about six species of 

 hardy herbs, perennials with the exception of a couple of 

 species of unintroduced annuals two of which are from 

 North America, and the third from Central and South

 Leaves petiolate, all opposite or the upper ones rarely 

 alternate. For culture, see Helianthus.

 according to the ancients, it turned with the sun). Helio-

 150 species have been described, although, in all pro- 

 bability, not more than 100 are entitled to specific rank)
