EPIPHYLLUM. 189 
This species has long been cultivated and has always been a great favorite on account 
of the ease with which it is grown and the abundance of large flowers it furnishes. These 
begin to open in the early evening and are perfect about midnight. 
According to Mr. Pittier, this plant is known as flor de baile in Venezuela. 
Epiphyllum latifrons Zuccarini (Pfeiffer, Enum. Cact. 125. 1837) was given as a 
synonym of Cereus latifrons when that name was first published. 
The name Cactus oxypetalus Mocifio and Sessé was the first one given to this plant, 
but De Candolle (Prodr. 3: 470. 1828) published the species as a Cereus, citing the above 
name as a synonym. 
The following hybrids were listed by Labouret (Monogr. Cact. 429. 1853) between 
Phyllocactus latifrons and some other species of Epiphyllum or related genera; Phyllocactus 
longipes, P. lothii, P. londonii, P. macquianus, P. maelenti, P. maurantianus, P. mexicanus, 
P. roseus albus, P. roseus superbus, P. selloi, P. smoli, and P. smith.
