RUMPHIUS'S HERBARIUM AMBOINENSE 



agrees more or less with Dendrobium crumenatum is Angraecum 

 angustis crumenis. I have thought that the material Rumphius 

 described might have presented two species growing together, 

 but after a careful study of the question I am now convinced 

 that the plant in question must be an Eria, probably Eria mo- 

 luccana Schltr. & J. J. Sm.

The plant is not a variety of Dendrobium papilioniferum J. 

 J. Sm. as I formerly supposed, although it is not impossible that 

 it is a hybrid. The suggestions of Linnaeus, Willdenow, and 

 Hasskarl, who respectively reduced this form to Epidendrum 

 spathulatum Linn., Cymbidium ovatum Willd., and Dendrobium 

 bursigerum Lindl., are certainly incorrect. The other form de- 

 scribed by Rumphius in this chapter is probably another species 

 of Dendrobium, certainly not Hysteria veratrifolia Reinw., as 

 Hasskarl has suggested.

It is possible that Dendrobium minax Rchb. f ., which I 

 formerly reduced to D. rumphianum T. & B., may represent some 

 other species. It is very doubtful whether or not the Bali plant 

 mentioned by Rumphius belongs with this species. Rumphius's 

 description of Angraecum flavum nonum agrees very well with 

 this species, but the figure closely resembles that of Angraecum 

 flavum septimum.

I cannot distinguish Rumphius's figure of Angraecum flavum 

 nonum (t. 46, f. 2) from that of Angraecum flavum septi- 

 mum (t. 45). The description of the former, however, agrees 

 very well with Angraecum flavum sextum moschatum Rumph.
