OPENING OF PALM SPATHES WITH AN AUDIBLE REPORT. 67 
This species is clearly allied to 4. Candollianus, appendiculatus, and 
hydrophilus, but belongs to neither. The Rev. M. J. Berkeley con- 
siders it to approximate most to the first of these, with which he is 
well acquainted, but at the same time to be distinct.

OPENING OF PALM SPATHES WITH AN AUDIBLE 
REPORT. 
By ALEXANDER SMITH, Esq. 
In the summer of 1861, it was stated to Dr. Seemann that a Palm 
spathe in the Royal Botanic Gardens at Kew had opened with an audible
