Abstract
Paracaryum intermedium andP. boissieri differ only in their inflexed or flattened fruit wings, and often occur in mixed populations on Mt. Katherina, Sinai. This and cultivation experiments suggest that they may represent forms of a single species only. The fruit characters mentioned therefore are hardly useful for a generic separation ofParacaryum andMattiastrum.
