Throughout SE Asia, palms are important in agroforestry systems and homegardens. Most species are used for multiple purposes based on both physical and nutritional properties of the palms. Except for a few commodities of worldwide importance such as palm oil and coconut, many palm products either do not figure in trade statistics, or they are merged with other products in a way, which makes it difficult to assess their importance. Here we focus on these products that are not prominent in national trade statistics and we review their sustainability and economic importance in SE Asia. We rank the most important palms according to their versatility, which is an extremely important property, especially for smallholders who practice subsistence agriculture. We conclude by listing a number of recommendations for future research directions based on experiences from the recently completed EU 7th Framework project (EU-PALMS 2009-2013.

The flowers of Ceroxylon ceriferum share a lack of postgenital fusion in the perianth with members of the tribe Phytelepheae. The elongation of the receptacle is reminiscent of the receptacle expansion in Phytelepheae. However, the multistaminate condition in C. ceriferum is less extreme than in the Phytelepheae, and the stamen initiation is centripetal as opposed to centrifugal in the latter.
