“Borneo :—Mount Kinabalu, at an altitude of 7,200 feet. 28th 
August 1913.” J.C. Moulton. No. 103. 
The specific name is in memory of Mr P. Skene Keith, an 
officer in the service of the British North Borneo Company, who 
accompanied Mr Moulton on his ascent of Mt. Kinabalu and who 
lost his life in Borneo shortly after his return from the expedi- 
tion. Iam indébted to Mr R. A. Rolfe of Kew for the reference 
of the species to its proper affinity.
