Notes on Taxonomy and Nomenclature

Top of page The generic name is derived from the Greek helios, for sun and trope, for turning, suggesting that the leaves and flowers turn towards the sun, however, this is not the habit of this species. The species name, indicum relates to India where it is supposed to be a native plant species, however, Waterhouse (1993) considers H. indicum to be of tropical American origin. Its closest relative is H. elongatum, a species of south-eastern South America (See Notes on Geographic Distribution) (Johnston, 1928).

Description

Top of page H. indicum is an erect, robust, coarse, succulent annual herb with branched stem and strong taproot. Usually the plant attains a height of 1 m, but sometimes it may grow as tall as 1.5 m. Stem deeply grooved and covered with large, coarse, white hairs. Leaves opposite or alternate, 3-15 cm long, 2-10 cm wide, ovate to oblong-ovate, with dense, long white hairs on both surfaces. The lower surface of the leaf is pubescent, acute or acuminate, margin with shallow undulating teeth, the base narrowing and extending down along the petiole to form wings on both sides. The lower surface of the leaves prominently veined, the upper surface coarsely rough and grooved. Inflorescence internodal, an unbranched and very rarely dichotomous helicoid cyme, the peduncle portion 2-3 cm long, pubescent, the fertile portion 9-16 cm long. Flowers bisexual with five sepals, lanceolate, 2-3 mm long; Corolla lilac to occasionally white. Fruits angular with an apical beak, 2-3 mm long, glabrous with two lobes which spread apart and separate to give two nutlets at maturity.

Distribution

Top of page H. indicum is distributed widely throughout the world's tropical regions and it has proved difficult to establish its precise origin. The name suggests an Asiatic origin, and some sources (for example, Holm et al., 1977; Kostermans et al., 1987) indicate it originates from the Old World, but Waterhouse (1993) consider it to be of tropical American origin.

H. indicum occurs as a weed in Africa, the Caribbean region of South America and Central America, tropical regions of North America and southern Asia. Recently it has been introduced to Australia where it is found in Northern Territory and Queensland (Craven, 1996).

Habitat

Top of page H. indicum is a weed of disturbed habitats from sea level to an altitude of 1000 m almost throughout the tropical and subtropical regions of the world. It does not occur in colder regions. The plant is usually associated with wet, fertile soils, often near rivers and lakes, fallow rice fields, roadsides and waste areas.

Biology and Ecology

Top of page H. indicum is a coarse annual weed and one of the most commonly encountered species of the genus. The plant reproduces by seeds which are produced on the long, curled, one-sided spikes. The seeds are produced for a long period and the flowers continue to produce new seeds while mature seeds are still falling (Tadulingham and Venkatanarayana, 1932). Its ability to grow in periodically wet or partiailly flooded situations enables it to establish in crops under conditions where weeds sensitive to excess water could not endure.

Notes on Natural Enemies

Top of page Few natural enemies of H. indicum are known. The species is distributed widely throughout the world's tropical regions, and it has proved difficult to establish its precise origin, although South and Central America seem most likely. Arthropods and pathogens should be studied in these areas to establish if any have biological control potential. A few natural enemies, especially pathogens, have been recorded, mostly in India, apparently with little importance.

Impact

Top of page H. indicum is common in tropical countries, being a major weed of sugarcane in Indonesia and the Philippines (Holm et al., 1991) and of maize in Myanmar, Thailand, Vietnam and the Philippines (Waterhouse, 1993). It is also reported as a weed of rice in Bangladesh, Indonesia, India, Laos, Malaysia, Philippines, Thailand and Vietnam (Moody, 1989). In Venezuela, it is a common weed of sugarcane in Aragua and Portuguese states (Rincones, 1975, 1989), of sesame (Sesamum indicum) (Prieto and Leon, 1975) and of several other crops (Anzola, 1989). It is a common weed of crops in several other countries including Taiwan, Tanzania and Trinidad.

In addition to being a weed in different crops in various tropical and subtropical regions of the world, H. indicum, like several other members of Boraginaceae, possesses pyrrolizidine alkaloids which have a hepatotoxic effect in cattle (Birecka et al., 1980; Morris and Zambrano, 1991).

Uses

Top of page H. indicum is considered as an ornamental plant and often planted in gardens (Kissmann and Groth, 1992). Batra et al. (1969) suggested the use of H. indicum as trap plants to control flea-beetles (Psyliodes brettinghami, Phyllotreta cruciferae, Luperodes spp. and Chaetocnema basalis) that damage crop plants in India, especially vegetables and cereals.

Similarities to Other Species/Conditions

Top of page H. indicum is a coarse, annual weed and one of the most commonly encountered species of the genus Heliotropium in the tropical and sub-tropical zones. H. indicum differs from most other weedy species in its lilac flowers, but these are sometimes white and a more reliable character is the pair of strongly divergent carpels with bidentate tips. The closely related H. elongatum has carpels parallel or only weakly divergent, longer (commonly 4-5 mm long), and without the strongly bidentate apices.

A number of other species can occur as weeds, of which the most important is H. europaeum (see separate data-sheet). This normally has white flowers with yellow throats, but can also be distinguished by its 4-lobed fruit. H ovalifolium in West Africa has much smaller, densely hairy leaves.

Prevention and Control

Top of page There is little information available on the chemical control of H. indicum. However, a few experimental results are mentioned in the literature.

Methabenzthiazuron, dichlormate and nitrofen were found to effectively control H. indicum when applied pre-emergence to wheat (Tosh, unda).

Kostermans et al. (1987) indicate moderate susceptibility to 2,4-D and MCPA when young. Lorenzi and Jeffery (1987) suggest 2,4-D + dicamba for use in non-crop areas.
