traced passing into the curious short transverse bars between the ribs which form the 
* cancellation " or fenestration of many Scitaminex in Borneo and Sumatra. In this 
form, too, the margin of the sheath in the upper part is fringed by acuminate 
fimbriate processes as much as 3 cm. long. In the typical form there is nothing of 
this, the sheaths are not even cancellate, nor are their margins fringed or broken up in 
any way. The inflorescence and flowers are identical in both forms. 
The calyx and lip are gland-dotted, the stylodes fleshy, oblong, truncate, with short 
blunt teeth, the style slender, hooked at the tip, with a very small stigma.

“ Flowers yellow, fruit mangosteen colour." 
This fine plant appears to be nearest to A. macrocephala, K. Schum., one of the two 
plants included in his section Amomiceps, differing largely, however, in its many-bracted 
compound inflorescence, the denticulate bracts, and the presence of an appendage to 
the anther. The other plant given in his section Amomiceps, namely, A. capitellata, 
Jack., has nothing in common with A. macrocephala, and is very closely allied to 
A. javanica, Blume.

* Fruit greenish ochre, flowers white, lip yellow." The flowers have not been
