ceous, up to 11 cm. long and 2.3 cm. broad. Inflores- 
cence about as long as the leaves, breaking through the 
leaf-sheaths approximately opposite the base of a leaf, 
about 10-flowered; rachis becoming slightly thickened 
upward ; bracts ovate, 1-2 mm. long. Dorsal sepal slight- 
ly coneave, elliptic-ovate, obtuse, several-nerved, about 
14 mm. long and about 9 mm. broad. Lateral sepals 
broadly ovate, obtuse, slightly oblique, attached to the 
column-foot, several-nerved, about 15 mm. long and 10 
mm. broad. Petals narrowly obovate, obtuse, several- 
nerved, attached to the column-foot, about 13 mm. long 
and 7 mm. broad near the apex. Lip articulated to the 
long column-foot, strongly saccate, carinate, Inconspic- 
uously 5-lobed, with the four lateral lobes erect: sac to- 
ward the apex of the lip, about 12 mm. long, 6 mm. in 
diameter dorso-ventrally and 2-3 mm. laterally, ecallose 
within. 
Macropodanthus is apparently a most distinct genus 
and is somewhat difficult to place as to relationship a- 
mong the known genera. It seems to be most closely al- 
lied to Aerides and possibly should be placed between 
Aerides and Rhynchostyls in the system proposed by 
Schlechter in Notizbl. Bot. Gart. Berlin 9 (1926) 563-591. 
Macropodanthus differs from Aerides in having the 
column-foot much more strongly developed, in the struc- 
ture of the lip, in having the petals as well as the lateral 
sepals attached to the column-foot, and in the structure 
of the column (especially of the rostellum). 
A sketch of the flower, drawn by Ramos, gives the 
coloration of the flower in part as follows: sac of the lip 
green, with the upper part pink and yellow; column-foot 
brown; the half of the lateral sepals nearest the column- 
foot yellow with the apical half white. No color is noted 
for the petals and dorsal sepal; possibly they were the 
same color as the lateral sepals.
