dilated above the base and longer than the ovary; from H. epiphylla by its 
smaller leaves, broader dorsal sepal, the posterior lacinia of the petals 
straight and the anterior one shorter, and shorter lobes of the lip; from 
H, bantamensis by the broader gradually narrowed leaves, more numerously 
flowered spike, the sepals not acuminate, the petals with a shorter and 
‘broader posterior lacinia, shorter and unequal lobes of the lip, a longer 
spur, and smaller staminodes; and from H. keyensis Schltr. by the lateral 
sepals not being acuminate, the longer anterior lacinia of the petals, the 
shorter lacinia of the lip, the longer straight spur, and the stigmata nearly 
equaling the anther canals in length. 
Doctor Robinson suggested in his field notes, that the plant might be 
Orchis amboinica minor altera Rumph. Herb. Amb. 6: 118, t. 54, f. &. 
This, however, certainly is not the case. Rumphius’s plate represents a 
plant with broader leaves and much smaller flowers, while his description 
does not at all suit Robinson’s plant. Rumphius’s figure represents a species 
of Peristylus. 
The species belongs to the Salaccensis section.
