Introduction

  • An attractive undergrowth palmlet with very much the appearance of D. louvelii, but with shorter inflorescences and staminate flowers with six rather than three stamens. The species name refers to the pretty appearance of the three known specimens. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Discussion

  • S. This taxon was included in the folders of D. louvelii in the Paris Herbarium. However, the inflorescence has a relatively shorter peduncle and the sometimes zigzag rachis gives the inflorescence a different appearance, but it is the staminate flowers which immediately separate the taxon from D. louvelii. There are six biseriate stamens, in form reminiscent of those of D. nodifera. The two collections from the lower Mangoro are clearly conspecific; the collection from Andasibe differs slightly in having a zigzag inflorescence rachis. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Diagnosis

  • D. louveliifoliis et inflorescentiis superficialiter similis, sed pedunculo breviori floribus staminatis 6 staminibus biseriatis bene distincta. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A
