The present species was introduced by Messrs. Sander 
& Sons, St. Albans, through their collector, Mr. W. 
Micholitz, about seven years ago, and it flowered in the 
collection of Mr. Elijah Ashworth, Harefield Hall, Wilms- 
low, in January, 1901, when it received a First-class 
Certificate from the Royal Horticultural Society. It is 
said to have been imported with D. atroviolaceum, D. 
Johnsoniae, D. spectabile, and D. Madonnae ; this probably 
fixes its habitat as New Guinea. The plant subsequently 
died, but there is another in the collection of Sir Trevor 
Lawrence, Bart., at Burford, which is believed to be the 
only surviving one in Europe, and this was kindly lent by 
Sir Trevor in April of last year, in order that it might be 
drawn for the Botanical Magazine. It belongs to a section 
of the genus of which five others have been figured in this 
work, namely, D. macrophyllum, A. Rich., var, Veitchia- 
num, Hook. f. (t. 5649), D. atroviolaceum, Rolfe (t. 7371), 
D, Hodgkinson, Rolfe (t. 7724), D. spectabile, Maiq. 
(t. 7747), and D. Madonnae, Rolfe (t. 7900). They belong 
to the section Dendrocoryne, originally established by 
JuNE Ist, 1907.
