Biology and Structure of Phytomonas staheli sp. n., a Trypanosomatid Located in Sieve Tubes of Coconut and Oil Palms

Abstract
SYNOPSIS. Phytomonas staheli sp. n. is described from the oil palm (Elaeis guineensis) and the coconut palm (Cocos nucifera) of Surinam, South America. The phytomonad is the probable cause of “Hartrot” in the coconut palm and “Marchitez sopresiva” in oil palms. Parasites are confined to the sieve tubes in palms. Some success was obtained at cultivation of the organism from Elaeis.
