    Description
    Global description

    Rhamphicarpa fistulosa is an annual parasitic herb with hail simple stem very branched, up to 40 cm high, with often bent growth habit. It becomes black when drying. The leaves are opposite, subopposite, filiform, straight or deeply divided into 1 to 3 pairs of filiform segments and a terminal segment, generally from 1 to more than 4 cm long. The flowers are solitary at the base of the leaves or terminal, in narrow tube flaring at the end, long of 2 to 4 cm, white, cream or pale pink in colour. The fruit is a capsule of 7 to 10 mm long surmounted by a curved beak.
     
    Cotyledons

    Cotyledons filiform, very slim.
     
    First leaves

     First leaves are opposite, simple, filiform, 2 to 4 mm long. They quickly become deeply divided into filiform segments. Dark green in color, becoming very quickly blackening when is cut.
     
    General habit

    Grass with erect growth habit or somewhat curved, with a slender stem simple to highly branched, reaching up to 40 cm in height.
     
    Underground system

    Stem

    Slender stem, quadrangular, solid, glabrous, often branched, 20 to 40 cm high.
     
    Leaf

    Sub opposite or opposite leaves, rarely alternate, simple. They are carried by filiform petiole, 3 to 10 mm long. The blade is entire or deeply divided with 1 to 3 pairs of filiform segments, less than 1 mm wide and a filiform terminal segment. The blade is of very variable length of 1 to more than 5 cm in length, the segments are 2 to 20 mm long. Both sides are glabrous. The margin is entire.
     
    Flower

    Flowers solitary, axillary or terminal, in close tube, 2 to 5 cm long, white, cream or pale pink in colour. They are carried by a peduncle, 9 to 20 mm long. Two thread-like bractlets of 1 to 5 mm long are situated at mid-height of the stalk. The calyx has five sepals fused in tube at the base, 6 mm long, with lobed top corner and lengthily acuminate. The corolla is formed of a tube of 20 to 40 mm long and 10 to 15 mm diameter at the end, terminated by rounded to spatulate lobes, opening only at night.
     
    Fruit

    The fruit is an ovoid capsule with 2 loculus, slightly flattened longitudinally, about 1 cm long, at the top ending in sharp beak,  4 to 7 mm long, inclining on one side. The sutures of the capsule are finely winged. The capsule is dehiscent on one side, and contains many seeds forming a powder.

      Reproduction
      Rhamphicarpa fistulosa is an annual plant hemiparasitic to rice and poaceae, which quickly multiplies by its many seeds. The plant produces fruits very rapidly and releases, by dehiscence of the capsule, its many powdered seeds.

        Ecology
        Rhamphicarpa fistulosa is a semi-aquatic plant, growing in peaty soils over rock substratum, on or between rocks on shallow, slow running streams, but more frequently in grassy swamps, temporary or permanently flooded areas like inland valley swamps and poorly drained rain-fed lowland rice fields. It can grow from sea level up to 1750 m of elevation.

        Comoros: Absent.
        Madagascar: Rhamphicarpa fistulosa is a species of savannah, common in swampy areas, the edges of ponds and rice-growing lowlands. Parasitic species of poaceae, it infests insufficiently irrigated paddy fields, especially rice zone of medium and low altitude . Adult plants resistant to certain water blade. It also parasites the millet, sorghum and other spontaneous Poaceae.
        Mauritius : Absent.
        Reunion : Absent.
        Seychelles: Absent.
        Togo: High and medium levels of Rhamphicarpa fistulosa infestation in lowland rice fields in the Savannah Region are found on soils with high coarse sand content, high potassium content, low fertility and low water retention capacity located in the northwestern part of the zone and at higher than average altitudes, while low levels and absence of infestation are more likely to be found on finer-textured soils found further east in the zone.

            Global harmfulness

            Not yet considered to be a widespread problem, however, it has the potential to become more important in the near future (Raynal-Roques, 1994; Rodenburg et al., 2010). It parasitizes on cereal crops like rice and there are indications that it is increasingly occurring on rain-fed lowland rice (Rodenburg et al., 2011).


            Local harmfulness

            Benin: Rare but abundant when present.
            Burkina Faso: Rare but abundant when present.
            Comoros: Absent.
            Madagascar: Rhamphicarpa fistulosa is frequent weed and locally abundant in rice fields deficient in irrigation. It weakens or completely kills the rice in variable extent spots, giving a burning sensation (hence its Malagasy name "Angamay").
            Mali: Rare and scarce.
            Mauritius: Absent.
            Nigeria: Frequent and scarce.
            Reunion: Absent.
            Senegal: Rare and scarce.
            Seychelles: Absent.
            Tanzania: Rare but abundant when present.
            Togo: Rhamphicarpa fistulosa first mentioned in 2003 has become a major weed of lowland rice cultivation in the Savannah Region in northern Togo.
            Uganda: Rare but abundant when present.

              Management
              Global control
              Genetic variation in resistance and tolerance levels was observed among rice cultivars; fertilizer applications significantly reduced parasite numbers, biomass and negative host effects (Rodenburg et al., 2011). It is also hypothesized that improved water management (flooding) can reduce Rhamphicarpa abundance.

              Management recommandations for parasitic plants in rice fields: http://portal.wiktrop.org/document/show/24

              Local control

              Togo: In the Savannah Region in northern Togo, it is recommended to check that the rice seeds used are not contaminated by Rhamphicarpa fistulosa seeds, to carry out late sowing of rice and to set up cropping systems including rotations with legumes such as soybean, groundnut or cowpea, and vegetable crops.
