EPIPHYLLUM. 199 
is said to be a native of Mexico, but probably is of hybrid origin. It is described as having one of 
the largest flowers among cacti, rivaling Selenicereus grandiflorus and Heliocereus speciosus. 
Epiphyllum splendens Hortus (Ann. Fl. Pom. 343, 1839) is referred here by the Index 
Kewensis. It is, however, described on page 345 and illustrated on plate 44. This illustra- 
tion is very different from that of Paxton.

PHYLLOCACTUS HAAGEI. 
This is doubtless a garden hybrid related to Epiphyllum ackermannii. It has large 
flowers, 12.5 cm. broad, at first flesh-colored, becoming carmine.

This was figured and described by Watson with flowers 15 cm. long and bread, nodding 
and white(!); doubtless of hybrid origin; it may be the same as Phyllocactus roseus 
grandissimus (Monatsschr. Kakteenk. 19: 182. 1909).

PHYLLOCACTUS RUESTII Weingart, Monatsschr. Kakteenk. 24: 123. 1914. 
We have not seen this plant and Mr. Weingart, who described it, says that he does 
not possess either living or herbarium material but that it is still growing at Halle, Germany.
