Nota. Effugisse videtur Hookerum cl. aliosque autores excepto cl. 0. Arnes, Reichenbachium 

 in Flora Vitiensi nomen plantae in BonpJantia V. 54 sub Ih^ia myosuro descriplae in Eriam 

 (seil. Phreatiam) stachyuram mutavisse. Nomen Eriae (v. Phreatiae) myosuri solummodo 

 plantae paeificae adhibendum esse vult Reichenbachius. — Cl. J. J. Smith haud feliciter hanc 

 speciem cum P. densiflora Lindl. conjunxit, illumque secutus est cl. Oak es Arnes 1. supra 

 c, qui ceterum Synonyma P. myosuri suae recte compilavit et primus errores a Reichenbachio 

 commissos in lucem posuit. — Observavit cl. J. J. Smith specimina in horto Buitenzorg culta 

 autogama esse. Fovea stigmatica enim ineunte anthesi floris succo gelatinöse et viscoso adeo 

 scatet, ut Saccus pollinia a^ttingat, quo facto statim massulae pollinis utriculos per succum et 

 foveam stigmaticam in ovarium emittunt.
