Peristeria, Booker. From peristera, a dove ; 

 in allusion to the dove-like appearance of the 

 column. Linn. 20, Or. 1, Nat. Or. Orchida- 

 ceas. This is a genus of splendid plants, the 

 most remarkable and interesting of which is 

 the P. eldta ; it produces a long spike of 

 yellowish-white waxy flowers, yielding a very 

 peculiar fragrance. In the neighbourhood of 

 Panama, it is known to the natives by the 



appellation of "el Spirito Santo," and tho 

 reason for this name is quite obvious on look- 

 ing at the flower ; the centre of it exhibits a 

 column which, with its summit and the pro- 

 jecting gland of the pollen-masses, together 

 with the erect wings, bears 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, leaf- 

 mould, and sandy peat, and must not be over- 

 watered at any season, more especially when 

 torpid ; they are increased by separating the 

 pseudo-bulbs. See Acineta. Synonymes: 1,
