serratum obtusum breve formantia; petala quarta longiora et duplo latiora 
Obovata brevi-aeutata reflexa, haec omnia margine plus minus undulata, 
labellum e basi cuneata trilobum, lobi laterales late obovati antice denti- 
culati verosuli, lobus intermedius oblongus acutis margine valde undu- 
latus, callus longitudinalis bisuleatus e basi medium usque ibique divisum 
in lamellas 3 (quarum intermedia longior) supra eleganter papillosas 
fimbriatasve. Gynostemium pro flore longiusculum, stelidia satis magna, 
uncata reflexa, filamentum longum subulatum. Sepala petalaque pulchre 
violaceo-purpurea pallidius marginata, mentum et basis sepalorum extus 
albida, labelli basis et lobi laterales albidi purpureo suffusi, lobus inter- 
mediüs intensius coloratus fere ut petala, sepalum dorsale 2,3 cm 
longum, 8—9 mm latum, lateralia 2,5 cm longa 9 mm lata, mentum 
1 em longum, petala 3—3,2 cm longa antice 1,5—1,6 cm lata, labellum 
2 cm longum et inter lobos laterales 1,5 cm latum, lobus intermedius 
6,7—7 mm longus 5 mm latus. 
The plant, of which I have only seen a spike, certainly resembles 
Dendrobium Phalaenopsis, bigibbum, dicuphum and other Dendrobia from 
Northern Australia or New Guinea. The most striking characteristic, 
however, is that the petals, and especially the sepals, are more or less 
twisted or even curled, and the plant connects the Dendrobes of the 
Phalaenopsis-group with those having an affinity with D. undulatum, the 
crests of the lip being elegantly fringed and jagged. The plant shows 
also an affinity with D. Sumneri, and at first I was not sure that we 
had not to deal with this plant, described from an imperfect specimen 
by F. v. Müller (see Flora Austral, VI, 278), and not very well repre- 
sented in European collections. D. Sumneri, however, is evidently a 
much smaller plant, not to mention that it has other botanical charac- 
teristics.
