Colombian communities
In a remote sensing project for rapid ecological evaluation, S. crassiflorus was found in Colombia inhabiting two areas that were evaluated.
A flood prone coastal region:
Acanthospermum australe Acicarpha tribuloides Ambrosia tenuifolia Androtrichium trigynum Azolla sp. Bacopa monnieri Baccharis articulata Cardionema ramosissima Centella asiatica Cephalanthus glabratus Chenopodium retusum Cuphea carthagenensis Cynodon dactylon Cyperus haspan Cyperus virens Enydra sessilis Erechtites hieracifolia Eryngium pandanifolium Hedyotis salzmanii Ischaemum minus Juncus microcephalus Nymphoides indica Panicum racemosum Paspalum nicorae Petunia litoralis Pluchea sagitalis Polygonum punctatum Pterocaulon sp. Ranunculus apiifolius Sesbania punicea Solanum platense Thelipteris interrupta Xyris jupicai Zizaniopsis bonariensis
A sandy area near to a forest:
