Salak have uniformly dark red flowers. At the same time their pubescence 

 is variable, the leaves being quite glabrous, and the ligula glabrous and 

 ciliate at the top in the yellow and red flowered specimens, whilst in the 

 orangeflowered ones, the ligula is ciliate and woolly at the backside and 

 the costa is densely pubescent. 



The bracts are also rather variable as to the thickness and roughness 

 of the reticulation of the bracts; in one specimen of a spike the transverse 

 septs are very much widened and confluent leaving the interstices only 

 as small erosed pits in a homogenous surface. The surface here is almost 

 smooth on touching. There are however transitions. 



- The curious aerial roots by which the supraterrestrial creeping rhizomes 

 of this species climb along tree stumps, etc. high above the soil have 

 been amply described formerly. (Bull. 1904, 46). Among the Malaccan 

 species described by RIDLEY, there is only one, that is said to have a rhi- 

 zome elevated above the ground, H. grandis, and the description does 

 not quite disagree with the species under consideration. 



So the irregular transverse ribs of the bracts are mentioned by Ridley 

 and in both species the stylodes are very considerable, though they are 

 only 12 mm. long in H. Pininga and 25 mm. long in H. grandis (which 

 might be a typographical error), and some of the differences may be a 

 consequence of the dried state in which RIDLEY 's specimens were examined. 

 In any case if the two species be synonyms, H. Pininga has the priority.
