There are however a few points which deserve to be mentioned not being- 

 mentioned by other writers. 



The staminodes usually considered as to be wanting in this group (e. g. 

 RlDL. 1 899, 140) are very conspicuous in our specimens especially in adult 

 buds, but also good visible in open flowsrs. They are inserted between the 

 filament and the lip and a little above the base of the latter next to the base 

 of the auricles. Their free top is obovate, flat, 0.15 mm. long and wide^ 

 at the bottom they pass into the hairy line which separates the filament 

 from the lip (fig. 1.) 



The ovary is glabrous, but there is a ring of erect hairs at the top, 

 surrounding the calyx. 



The stylodes are the longest I met with in any species of this group, 

 being 16 mm. long; they are linear-subulate, connate at their base and 

 enveloping the style. The stigma is cupshaped with an apical linear os- 

 tium, very hairy with deflexed hairs, the style is rubescent only near the top. 



The calyx is short, about 3/5 or 3/4 of the tube length (30—35 mm ) 

 tubular, di'ated and subspathaceous above, complanate with a thickened 

 rib at each side, subtrilobed, lobes obtuse, each with a rather long thorny 

 tooth below the top, thinly membranous edges ciliate, rest glabrous. 



The bracteole is shorter than the calyx, linear-lanceolate acute, carinate 

 with a thorny mucro below the top, complicate and embracing the calyx tube.

This species is very much variable in the colouring of the flowers. 

 The most common form in Java, Mt. Gede, etc, also found in Sumatra 

 on mt. Ophir, has uniformly sulfureous flowers. On the two other locali- 

 ties Mt. Galungung and Mt. Sembung the flowers are outwardly red- 

 orange-coloured, but with a yellow lip. Those specimens collected on th e
