long spike of yellowish-white waxy flowers, yield- 
ing a very pecut'ar fragrance. In the neighbour- 
hood of Panama, it is known to the natives by the 
appellation of “ el Spiritn Santo,” and the reason 
for this name is qtiite obvious on looking at the 
flower ; the centre of it exhibits a column which, 
with its summit and the projecting gland of the 
S ollen-masses, together with the erect wings, 
ears a very striking resemblance to the figure of 
a Dove: whence the English name of the genus 
Dove-flower. The species should be grown in pots 
well drained, in a mixture of fibrous loam, lenf- 
mould, and sandy peat, and must not be overwatered 
at any season, more especially when torpid; they 
are increased by separating the pseudo-bulbs.
