yellow in the centre, veined with red brown ; a third form has 3 sessile elliptic leaves 
2-2} in. long, and a very stout 3-4-fld. scape, the flowers are straw coloured, finely 
lined with dull pink ; a fourth form from a lower elevation has leaves 1-23 in., and 
a slender 2.fld. scape, the flowers arelarge white. The breadth of the midlobe of the 
lip in this species varies from almost orbicular-ovate to dagger-shaped. The sheaths 
of the rhizome and pseudobulb are very membranous, red-brown. 
10. D. puminum.  '*Common at Singapore, with flowers yellow or cream 
coloured ; lip with a dark spot at the tip, or veined with red. The two forms look 
totally different, but I can find no structural difference. I never saw so many 
flowers in a head as in D. quadrangulare.” Ridley in litt.
