Description

Top of page C. reflexa has a similar morphology to Cuscuta campestris but is more robust, with a vine 1-2 mm thick, yellow or reddish, sometimes greenish. The flowers are also much longer, up to 10 mm long, white or pinkish with 5 obtuse lobes, much shorter than the lobes, in loose clusters. The capsule is elongated, conical, with a pair of simple stigmas on a very short single style. The seeds are large, 3-3.5 mm long.

Distribution

Top of page The distribution data provided on the map are incomplete, but C. reflexa is mainly confined to tropical Asia.

Risk of Introduction

Top of page Cuscuta species are quarantine pests in many countries.

Hosts/Species Affected

Top of page C. reflexa is a robust species occurring mainly on perennial tree and shrub hosts. Bhattarai et al. (1989) list 39 host species in 28 plant families in India.

Biology and Ecology

Top of page The biology of C. reflexa is largely comparable to that of Cuscuta campestris, but it is tropical in distribution, allowing it to behave as a typical perennial, persisting on its woody hosts for years. It has rather more chlorophyll than C. campestris giving it a greenish tinge, especially in young stages before it is attached to a host. It also differs in requiring short days for flowering.

Notes on Natural Enemies

Top of page Natural enemies of Cuscuta spp., including C. reflexa, are reviewed by CAB International (1987).

Impact

Top of page C. reflexa is less widespread than Cuscuta campestris, but is capable of serious crop damage where it does occur. It is classified as a 'principal' or 'serious' weed in Afghanistan, Nepal, India and Pakistan (Holm et al., 1979).

Similarities to Other Species/Conditions

Top of page C. reflexa is distinguished from Cuscuta campestris and many other species by having only a single style, and from other weedy species with this character by the style being shorter than the stigmas. Cuscuta monogyna, C. lupuliformis and C. japonica have styles longer than the stigmas, and also have smaller flowers less than 5 mm long (see Parker and Riches, 1993 for descriptions and key).

Cuscuta monogyna, with style and stigmas of about equal length, is a species of the Mediterranean and Middle East, eastwards to Afghanistan, which occurs mainly on woody shrub and tree hosts but also on some herbaceous plants. It is known to be troublesome in Iran, Pakistan, the former USSR, Afghanistan, Iraq, Jordan, Israel and Cyprus, on fruit trees including citrus and olive, and on vegetables including onion (Parker and Riches, 1993).

C. lupuliformis, with style about twice as long as the stigmas, is a European species, also occurring in India, Afghanistan and Brazil, which mainly attacks only tree and shrub species (Parker and Riches, 1993).

C. japonica, with style distinctly longer than the stigmas, occurs in East Asia, and is locally important in China and Japan on both woody and herbaceous hosts including potato and aubergine, but not tomato (Parker and Riches, 1993).
