The history of the introduction of this interesting little 
Orchid is obscure. It was first sent to Kew by the Editors 
of the ‘‘ Gardeners’ Chronicle” in May, 1896, and in June 
of the same year it was received from Sir Trevor Law- 
rence, without any indication of its origin. Sir Trevor 
sent it again in June, 1900, when he exhibited it at a meeting 
of the Royal Horticultural Society. Subsequently Mr. 
Rolfe identified these cultivated fragments with specimens 
collected by Dr. A. Henry near Mengtze, in the Province 
of Yunnan, Western China. 
The plant figured was presented to Kew by Mr. H. J. 
Klwes, F.R.S., and it flowered in a greenhouse in July of 
last year, under ordinary treatment. 
Arethusa, as now limited, comprises four other described 
Species; one is native of Japan, one of Mexico, one of 
Guatemala, and A, bulbosa, Linn. (Bot. Mag. t. 2204), the 
species on which the genus was founded, is a native of 
North America. 
Descr.—A. terrestrial, tuberous, scapose, glabrous herb, 
four to nine inches high. Tuber small, ovoid or globose. 
Leaves two or three, lanceolate, acute, the largest six
