Adenocalymna ( Adenocalymma ) comosum, Bignonia comosa Family: Bignoniaceae Yellow Trumpet Vine Origin: South America       The North-east-Brazilian Liana. The euphilic flowers of plants in the family Bignoniaceae display a spectrum of adaptive radiations, involving different pollinator groups. Besides melittophily (adaptation to pollination by medium - to large-sized bees), which predominates, flowers are pollinated by hawkmoths and bats. Each individual plant had a single inflorescence, which extends 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 (in the latter case on the same node), 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 sub-tending bracts and the two prophylls, bear groups of extra floral nectaries (single peltate trichomes). 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. |  |

 | Amphitecna latifolia, Enallagma latifolia Family: Bignoniaceae Black Calabash, Jicarillo, Savanna Calabash Origin: Costa Rica      Irregularly shaped tree with a bent and twisting, angular trunk. Simple, alternate ovoid leaves, thick and stiff. Waxy, glossy, and dark green, they contrast markedly with the lighter bark of the branches and twigs. Solitary flowers may be found growing amid the foliage or directly from the sides of the bare sections of the larger limbs and even the trunk. They are large, white, and composed of four thick petals fused into a bent and angular corolla tube that flares distally into a trumpet. The green calyx that covers and protects the developing flower during its early development is also fused into one piece, and it splits irregularly when the blossom finally emerges. Five long, black-anthered stamens and a central pistil are found within the perianth. Flowers are nearly present throughout the entire year. Fruits are large (4"in diameter), ovoid, indehiscent green pods with a smooth, glossy texture and an appearance similar to the fruits of the Jicaro ( Crescentia alata ) tree. Inside the thin, woody skin of the pod is a white fleshy pulp that surrounds several black seeds. The white pulp and seeds of the fruit are edible. Jicarillo wood is reportedly hard and rot resistant. Pollination: "Members of this genus are not bee pollinated - the flowers have peak nectar production at night, and you'll notice that they produce quite a lot of nectar. Bees are generally after the pollen, they would probably drown in all the nectar this species produces. The flowers are also pretty big - these are bat pollinated. The bees will certainly visit, but they are not effective transferrers of the pollen to the stigma". (By Susan Grose) |  |
