(1)Range.—Allamanda is apparently native to northern Brazil, Guyana, Surinam, and probably French Guiana (Liogier 1995, Pacific Island Ecosystems at Risk 2002, Tropilab Inc. 2002). The species has been planted and has become naturalized throughout the tropics (Howard 1989). |

(1)Yellow allamanda was listed in Victorian nursery catalogues as early as 1855. It was first recorded as naturalised in North Queensland in 1945 but had been grown in Brisbane Botanical Gardens in 1933. It is spread by wind and water and is now widely naturalised in rainforests from North and Central Queensland. There are several colour forms and it is widely available in nurseries. (2)Locally naturalised in wet tropical areas in Qld, for example next to the Bruce Highway between Cairns and Tully (NSW specimen). Distrib: Localised. Qld (North Kennedy, South Kennedy), WA (CK). (3)Stanton (pers. comm.) reports that A. cathartica has become quite invasive in several National Parks of far north Queensland. It is becoming common along roadsides between Silkwood and Tully (north Qld). |

(1)In NSW, the ten most serious invasive garden plants available for sale are Banana passion fruit, Broom, Cat’s claw creeper, Glory lily, Holly leaved senecio, Hybrid mother of millions, Lippia, Madiera vine, Mother of millions, and Yerba de hicotea. For Queensland, the ten are Coreopsis, Glory lily, Guava, Japanese honeysuckle, Mickey Mouse plant, Murraya, Parrot’s feather, Pink periwinkle, Taro and Yellow allamanda. (2)others such as exotic Passiflora spp., Mimosa diplotricha, Momordica charantia and Allamanda cathartica exert at least intermittent competition and can form dense mats to adversely affect the growth of a range of native species (3)Habitat. Amongst medium trees (Eucalyptus miniata woodland over weeds); in loam; occupying creeklines; growing in disturbed natural vegetation (on roadsides). (4)It invades well-drained soils on the fringes of rainforests, and paperbark swamps. |

(1)Abstract: Due to inquiries about the toxicity of ornamental plants to farm data available in the literature on this subject, feeding experiments were performed in cattle with the following plants: Allamanda cathartica, Nerium oleander and Thevetia peruviana of the Apocinaceae family...The only plants which caused lethal poisoning were Allamanda cathartica, Nerium oleander, Thevetia peruviana and Rhododendron indicum. (2)Cases of intoxication of pets were investigated by personal visits to residences, including homes, yards, apartments and common garden areas, in Rio Grande do Sul, Brazil, from 1998 to 2002 to determine the presence of poisonous plants. The plant species most commonly observed in cases of intoxication of pets (i.e. companion animals) were: Dieffenbachia picta [D. maculata], Sansevieria trifasciata, Allamanda cathartica, A. blanchettii, Euphorbia milii, E. pulcherrima, Lantana camara, Philodendron bipinnatifidum and Brugmansia suaveolens. This information will be useful to educate the public about the potential dangers of some common household plants to companion animals |

Possibly may be host of CMV. (1)No pests or diseases are of major concern. Yellow Allamanda is only occasionally bothered by caterpillars or mites. (2)Cucumber mosaic virus infecting Allamanda In collaboration with scientists at the Taiwan Agricultural Research Institute, Taichung, Taiwan an isolate of Cucumber mosaic virus (CMV) was identified in Allamanda cathartica showing severe mosaic, rugosity and leaf distortion symptoms. The virus measured approximately 28 nm and induces symptoms similar to those incited by CMV on indicator plants. The virus reacted with CMV subgroup I-specific MAbs in both ELISA and immunoblots. With primers specific to the 3'half of RNA3, a 1,115 bp DNA fragment was obtained by reverse transcription-polymerase chain reaction (RT-PCR) from total RNA extracted from diseased allamanda or inoculated Nicotiana benthamiana. Sequence analysis indicates that the coat protein ORF shares 91.8 to 98.9% identities with those of CMV in subgroup I and II. Results of MspI-digested restriction fragment length polymorphism patterns of the RT-PCR fragment and nucleotide sequence analysis indicate that the CMV isolate from allamanda belongs to subgroup IB. This research in this accomplishment contributes to ARS National Program 303, Components I and IV, and ARS Strategic Plan Performance Measure 3.2.5. (3)ORNAMENTALS, FLOWERING PLANTS: Allamanda cathartica `Chocolate Cherry' (allamanda) -- Bemisia tabaci (Genn.), sweetpotato whitefly: All stages heavily infested 100% of 200 plants in a nursery at Pembroke Park, Broward County (24 February 94, R. Carpenter and K. Vanyo). (4)CMV is known to naturally infect other ornamental shrubs, including some belonging to the Apocynaceae family: golden trumpet (Allamanda cathartica L.) and oleander (Nerium oleander L.) on both of which it causes pronounced symptoms of mottle and yellow areas or rings on the leaves (Bellardi and Bertaccini, 1993; Bellardi et al., 1996). (5)Pests, Diseases and Damaging Agents Pests: None of major concern except for nematodes. Purple Allamanda is only occasionally bothered by scale and mites. Diseases: Anthracnose, leaf spots, mosaic virus, root rots. Chlorosis and collar rot fungus. |

(1)Because of its rapid growth, pruning is often necessary, which can expose gardeners to the toxic sap that causes dermatitis symptoms of rash, blisters, and itch. Although incidence is much less common, plant parts are also toxic if ingested. All parts contain the toxic iridoid lactone, allamandin (2)Toxicity: All parts of the plant are reported poisonous. The milky sap can cause dermatitis on susceptible people. The plant’s sap cause mild and occasional reactions such as oral irritation and slight nausea from prolonged sucking of cut stems, rash from wiping the sap on sensitive skin. The plant has been given a bad reputation because of the drastic consequences of ingesting a quantity of the sap as a purgative. |

Unknown, but probably self-compatible as are other members of genus. (1)Abstract: Observations on the floral biology of Allamanda schottii Pohl showed that this species may be autogamous or allogamous. This contradicts the hypotheses of authors who have claimed that this species of Apocynaceae is only autogamous or only allogamous. The most frequent visitors to the flowers are butterflies, bees and wasps, but fertilizations is carried out by butterflies of the genus Phoebis. |

This bee can also be considered as a main pollinator of Allamanda (57.4%), D. wallichii (51.85%) and M. indica (48.39%), corresponding to about 50% of all floral visitors to each family (Table 1). A. mellifera was collected on the flowers of all plants except O. americanum. |
