THE SCITAMINEZ OF THE MALAY PENINSULA. 109 
The species can be divided into three groups. Acranthi, in 
which the flower spike is borne on the top of a leafy stem; A/e- 
santhi from the centre of a leaf tuft; and Kzxanthi outside the 
leaf-tuft. The last group suggests a close affinity with the 
Curcumas, of the section Hitcheniopsis. the real difference being 
the shape of the bracts and their more cone-shaped arrangement. 
Indeed C Kunstler? might almost as well be put in Gastrochilus 
asin Curcuma. Scaphochlamys described by Baker and referred 
to the neighbourhood of Liettariopsis, is truly a Gastrochilus, 
though in some respects a curious form. 
The Gastrochili inhabit woods, and though the species are 
usually local, that is to say restricted in area, they usually occur 
in quantity when met with. The flowers, which are very 
delicate and pretty, often sweet scented, open one at a time 
about midday, withering towards evening. They very rarely 
produce fruit. Many species are well worth cultivating, and 
grow readily in pots, or in shady spots in the ground. 
As the genus has been so much confused with Aempferia 
I submit a list of all species known to me with localities.
