and in December, 1915, the Kew plant, too, flowered for 
the first time in a tropical house where it had been 
grown and had thriven well under the conditions suitable 
for V. tricolor, Lindl., a species from Java, figured at 
t. 4432 of this work, which is its nearest ally in the 
genus. Though so closely related the two species differ 
very markedly in coloration, the sepals and petals of 
V. luzonica being white, not yellow, with a tinge or, at 
times, a defined spot of purple towards the apex, but 
with no trace of the brown blotches which characterise 
the sepals and petals of V. tricolor.
