108 THE SCITAMINEA OF THE MALAY PENINSULA. 
late acuminate about an inch long, narrow, spotted with red. 
Calyx one inch long tubular spathaceous entire spotted red, Co- 
rolla tube cylindric two inches long, 3 inch thick pale violet, 
lobes lanceolate cuspidate 4 an inch long 53, inch wide, white 
spotted with red at the tip. Lip orbicular cleft nearly to base, 
inner edges straight violet with a white spot at the base, one 
inch across. Staminodes orbicular narrowed at the base $ an 
inch long and wide, violet. Stamen, with the anther entirely 
outside the tube nearly + inch long, cells parallel rather fleshy 
pollen white, crest large reniform recurved broad entire violet, 
Style longer than the anther purple, stigma capitate deep red 
purple. Siam, Kasum, (Curtis). 
This curious and pretty plant grows abundantly on the lime- 
stone rocks of Kasum, the rhizomes being imbedded so deeply 
in chinks cf the rock that it is necessary to break away the rock 
to get at them. The gray green leaves and violet flowers make 
it an attractive plant. Structurally its most remarkable point is 
that the anther projects outside the tube entirely, instead of 
being concealed within as in the case of A’. elegans, etc, and the 
style is also visible from the outside. 
GASTROCHILUS. 
This genus was first distinguished by Wallich who des- 
cribed two species from Aempferta as it then stood by 
the lip being saccate or basin shaped, and by the habit. This 
form of the lip is peculiar to a few species only of the plants 
which I would refer to the genus, and which as I have already 
said is very distinct from the true Kempferia. The genus may 
be thus defined. Small herbs with a short rhizome. Stem tall 
and leafy or short. Leaves usually several together lanceolate 
or ovate. Inflorescence spicate with large bracts sometimes 
colored springing from the axils of the leaves, or independently 
on the rhizome cr terminal when the stem is tall. Flowers thin 
white, yellow or red. Calyx tubular. Corolla tube rather lone 
slender lobe oblong or lanceolate. Staminodes similar but slightly 
longer erect. Lip oblong or obcuneate entire or three lobed. 
Stamen thick and fleshy with an oblong anther, the crest of 
which is small rounded or lobed. 
Distribution : India, the Malay peninsula and islands.
