the anterior margin with a more or less distinct, irregular, 
gold-coloured ridge which continues halfway down the base and 
is finely denticulate at top, colour white, with yellow hue and 
a few longitudinal pink stripes in the lower portion; median 
lobe hastate, footlobes more in front than usual, base of the 
median: lobe consequently cuneate, shorter than usual, irregu- 
larly triangular, curved, gold-coloured, median portion rather 
normal, with 1 flower with longitudinal gold-coloured ridge — 
with white tip, median lobe 17—22 m.M. long, its base with 
brownspeckled margin as in normal flowers the anterior margins 
show; column normal '). 
c) Legit J. J. Suir in suo horto, February 1919. 
Habitat Mentawei islands. 
Petals with callus as on the lip, red speckled. 
d) Legit C. A. Backer near Sripit, South Kediri. 
Three flowers virescent. Lip somewhat disturbed. 
e) Legit J. W. Dannenporr, Weltevreden 1918. 
Flower pseudo-dimerous owing to absence of lip and coales- 
cence of the paired sepals. 
J) Legit C. van Zisp in suo horto, 1919. 
Youngest leaf cup-shaped at the base owing to coalescence 
of the margins. The cup encloses the bud and prevents its 
development. ; é

Legit C. van Zisp in suo horto, Luzon 1919. 
Leaf double (fig. 7 a and 4). The sheath from which springs 
the blade shows at first sight nothing abnormal, but on closer. 
inspection two tender lines appear which are to be considered 
as midribs of to blades. This splitting up of a blade isnot only 
incomplete but moreover very singularly executed. Both pro-— 
ducts of the division are unequilateral, the distant halves being 
normal, the portions that face one another narrow, through 
which circumstance the midribs are very near one another. 
: 1) That the sender of this specimen looked at it as a separate species is quite 
intelligible the more as according to his observation the inflorescence is like that of 
Schilleriana and the plant produces 2 to 3 stems at the same time. According to 
Swiru it is a real Ph. amabilis. : | Ge ie A
