Leaves are compound, with
leaflets arranged in threes (perennial species) or
pinnately (mostly annuals). The leaflet at the end of each leaf is transformed into a
branched
tendril.
Flowers are heart-shaped and have four pale yellow to orange
petals. The outer petals are pouched at the base and bent slightly outwards at the tip. The fruit is a capsule with two valves,
dehiscent in most species, but indehiscent in
D. scandens. ==References==
