Common name: Yellow Trumpet Vine
Botanical name: Adenocalymna comosum Family: Bignoniaceae (Jacaranda family)
Synonyms: Bignonia comosa
Native to Brazil, Yellow Trumpet Vine is a beautiful creeper with bright yellow
trumpet shaped flowers and glossy leaves.
Each individual plant had a single inflorescence, which extended above the
foliage, in the form of a simple, terminal, vertically orientated,
many-flowered raceme on a long, bracteose peduncle. The inflorescence
structure, with only one or two flowers open at a given time,
indicates continuous flowering over at least several
weeks, thus displaying a ‘steady state’ pattern . The flowers, on a stout
pedicel (20 mm long), have a 5-dentate tubular calyx. The calyx, the
subtending bracts and the two prophylls bear groups of extrafloral nectaries
(single peltate trichomes) These were foraged by large, blackish ants day and
night. The yellow-coloured corolla, measuring 7 mm in length, has a 28mm long
and 4mm-wide basal tube that widens rather abruptly into a campanulate limb.
