Habitat and Ecology [top]
Habitat and Ecology: This species occurs in medium to tall closed forest on deep, often clay-rich and more fertile soils, usually as part of the general shrub understorey in moderate to deep shade. C. pectinata is a plant of medium to higher elevations and moist conditions. It is recorded from a variety of substrates, but most frequently occurs on clay soils over limestone. Climate is tropical with wet, humid summers and milder, drier winters. Although often found on limestone substrates, it is by no means restricted to these, and it also occurs on granites and meta-sediments.
