Nota. Quae profert Reichenbach de racemo, quem »secundumt describit, minirae probo, 

 bracteas enim semper, etiam post anthesin, spiraliter dispositas inveni, saepius autem racemi 

 caulibus adeo sunt adpressi, ut flores vi quadam in partem oppositam premantur.

Nota. Planta certe D. hymenophyllo Lindl. (= Pedilonum undulatum Blume, Bijdr.) similis, 

 sed omnibus partibus minor. Specimina Wrayana a me examinata forlasse depauperata sunt 

 et si futuris temporibus specimina meliora et crebriora afferantur, haud mirarer, si ambae species 

 in unam eandemque conjungendae essent. Hodie melius esse puto de utraque specie singulatim 

 agere. Quae dicit cl. Ridley in opere suo »Materials for a Flora of the Malayan Pensinsulaec
