THE ORCHID REVIEW. 7 
Its hybrids, though not very numerous, form an interesting and 
beautiful series, and from the great probability that the pollen would be 
used for hybridising purposes as often as available, we can form some idea 
as to the rarity of the species, and the comparitive scarcity of flowers. 
P. X VEXILLARIUM (Fig. 1) was the first Fairreanum hybrid which
