Teees, sheubs or undeeshetjbs, rarely hbebs. Stem with watery juice, erect 

 or climbing, often furnislied with tendrils. Leaves alternate, or very rarely opposite, 

 generally compound, sometimes appearing simple by the suppression of the lateral

 the posterior part of the flower, prolonged anteriorly into a lamina, sometimes 

 double, or divided into glands opposite to the petals. Petals 0, or inserted outside

 unequal, imbricate or rarely sub-valvate ; claw velvety, or glandular within, furnished 

 in all the petals, or the anterior only, with a hooded or crest-like scale which often 

 terminates in an inflexed appendage. Stamens usually 8, sometimes 10, rarely 5
