acuminate; filaments white, nearly as long as the perianth-segments; style overtopping the

This species was named for Charles Darrah of Heaton Mersey near Manchester, 

 England (1844- 1903). His large and valuable collection of succulents, especially cacti, 

 was presented to the Corporation of Manchester by his widow and family and is now 

 housed in specially constructed houses in Alexander Park. In 1908 the late Robert Lamb 

 published a catalogue of 129 pages of this collection. 



The plant is cultivated in Mexico and is much prized as a potted plant for the patio ; 

 one of these was obtained by Dr. Rose in Ixmiquilpan in 1 905 (No. 909 1 ) . Living specimens 

 were sent home and these have repeatedly flowered in Washington and New York. It 

 flowers abundantly, its blossoms giving off a most delicious honeysuckle-like fragrance; 

 we have seen no specimens of wild plants.
