To this genus probably also belong Alpinia (S Oligocincinnus) strobilacea, K. Schum. ; 
A. chaunocolea, K. Schum.; A. sericiflora, K. Schum. ; A. Dekockii, Val.; A. gracillima, 
Val.; A. menostachys, Val., and leptostachya, Val., which Valeton refers to the affinity 
of Kolowratia. I have seen none of these species. 
The genus Alpinia, as described by K. Schumann in Engler’s * PHanzenreieh, H. 20, 
contains a somewhat heterogeneous collection of upwards of 140 species, arranged in six 
sections. Some of these sections appear to me to be sufficiently distinct to warrant their 
being raised to genera. In the present instance, 1 propose to separate a group which 
appears to be quite peculiar to New Guinea and the surrounding islands, and which is 
mainly characterised by the large broad and thick crest of the anther, which is also very 
hairy. In these species—or in many of them, at least—the development of the flower- 
spike is peculiar. "The inflorescence having developed to its full, or nearly full, length, 
produces spikes containing one or two flowers enclosed in long stiff bracts. These 
spikes then elongate as more and more flowers are produced, developing at last into a 
long cylindric spike covered with short imbricate hard bracts, so that, unless the flowers 
of the species are carefully compared, or a good set of the plant in different stages 
procured, it would be easy to mistake a specimen commencing to flower for a species 
distinct from the fully developed one.
