This native creeper of rainforest and coastal forest is a known medicinal plant in Indian medicine. The plant has been used as a treatment for a whole range of ailments including atrophy, bleeding gums,
cough, dysentery, cancer, skin infections, diabetes and liver disorders (see pdf here). The distinctive features are the hairs fringing the flower petals and the red glands at the nodes where the leaves join the stem. The leaf midrib is also distinctively hairy on the underside. Like many members of the Apocynaceae family, the shoots and leaves weep copious white sap when injured.

Hi David,
Many thanks for the information, I will visit JCU very soon. By the way, I love reading your web page, I have learned so much from you and excited to read some very details of plants we have had and continue to read more.
Have a Merry Christmas and A Happy New Year 2017.

It’s a pleasure Lucy. Yes, JCU has quite a bit around the edges of the forests, but the vine is pretty common throughout the lowlands, and you will probably see a fair bit around the forests near the Botanical gardens as well. Good to know you’ve found the blog useful. You too have a merry christmas and great new year.
Regards,
David
