The gloriously yellow Aeschynanthus flavidus

A striking lipstick vine that I initially thought was a very fine hybrid, but had my doubts when I verified the origin of the plant. A possible ID was suggested by experts from an institution - a plant first described by Mary Mendum in 1997. Besides the shocking colour, it also has a very tall and flaring calyx.

I wanted to get the publication to confirm the ID but there were always more pressing issues. Eventually, I obtained a copy from an acquaintance. I cannot verify the presence of glanduular hairs inside the flower but the other characteristics matched very well with this plant - the leaf shape, flower colour right down to the "crimson central line and the broken dots and dashes either side" of the lower corolla lobe. According to Mary's paper, when her specimen first flowered, the calyx was short (1.5-2 cm) but subsequent flowers had longer calyx of 2.7-3.4cm, as my series of photos also showed. The shrub also appeared to be rather rare, being found in only 3 localities in North Sarawak.

Just for the record, I had attached the published line drawing from Mary's paper for comparison. What the paper failed to emphasise is the very unique leaf colour -velvety purple-green hairy at the top and brighter green at the edge and pink at the bottom, very pretty even when not in bloom.

This is a treasured gift from my gesneriad friend from Borneo.

What a striking plant, especially that colour.

Yes this is a relatively rare find. Not too may Aeschynanthus have such striking large yellow bloom.

My first visit to your blog and I really like it. Given I have no experience with your part of the world, and that I am fascinated with plants and their ecology, this is a wonderful site.

Thanks, and be sure I will return.
