There is a dark green splash in the middle of the adaxial surface of most leaves. Smooth adaxial surface, tiny hooks along the leaf vein of the abaxial side. Inflorescences darker towards the apex, getting lighter towards the base.
There is an opposite branching pattern rotating around the stem. The stem is very red tinted.
This species was collected in late fall. The stems and branches were covered with prickles. While the coloration (green and yellow-orange) is representative of most of the leafage , there were also compound leaves entirely yellow-orange. As for the flowers, they had mostly all fruited, but I was able to find one still in a bud (Upper half of the frame in the second picture).
