This very striking novelty is a near ally of Arachnanthe 
moschifera, Blume, the musk-scented Spider-Oretid, which 
is very seldom seen in cultivation. It was introduced 
from Annam by Messrs. Sander & Sons, through their 
collector, W. Micholitz, and flowered at the Royal Botanic 
Garden, Glasnevin, in June, 1905. It is a member of a 
small genus, now estimated to contain about seven species, 
natives of the Malayan Archipelago, the adjacent peninsula, 
and the Himalayas, and characterized. among other things, 
by the possession of an articulated and mobile lip, in which 
respect it differs from Ienanthera. Three other species — 
have been figured in this work, namely, A. Lowi, Benth. 
(t. 5475) a Bornean plant remarkable for producing two 
kinds of flowers, of which the significance is still un- 
known; A. Cathcartii, Benth. (t. 5845), a Himalayan plant 
which is seldom met with in cultivation at the present 
day; and A. Clarkei, Rolfe (t. 7077), another Himalayan 
species which is also rarely seen. It may be added that 
Marcu Isr, 1906.
