Ochroma pyramidale

O Dowd, D. J. (1979). Foliar nectar production and ant activity on a neotropical tree, Ochroma pyramidale. Oecologia 43 233-248. 

Wiedemann [130] used samples of redwood Sequoia sempervirens), balsa Ochroma pyramidale/lagopus), quebracho bianco Aspidosperma quebracho-bianco) and beech wood (Fagus spec.) to determine the mechanical properties of wood by means of TMA and DSC. Flexure measurements as depicted in Figure 23 show different, highly reproducible onset temperatures for breakdown in the chosen samples from the very light balsa wood to the very hard South American quebracho bianco and - for comparison - bamboo. TMA together with DSC results indicates that such breakdowns take place only after the complete decomposition of cellulose.
