<div type="discussion"><p>C. flabellatus is primarily a plant of lowland dipterocarp forest at altitudes up to c. 500 m above sea level. Some forms retain the juvenile leaves consisting of a single pair of broad leaflets, even in high-climbing stems. This form was described by Beccari asC. flabellatus. Furtado named those forms with several pairs of leaflets as C. flabelloides. We now have a wide range of specimens of both forms and intermediates have been collected. It is noteworthy that inflorescences have never been found on the form with a single pair of leaflets. This species could be confused with C. javensis and its allies; the inflorescence of C. flabelloides is much finer, young leaves are pale green rather than pinkish and the curious dull bluish-green cast to the leaves of C. flabelloides is absent in C. javensis. C. gonospermus is superficially similar but has well defined petioles.</p></div>
