Loc., Malay Peninsula, in dry hill woods at an altitude of 
from i 5 ooo to 3,000 feet on the Larut Hills, Perak, and on 
Kedah Peak in Kedah. Coll H. N. Ridley. 
I published a short account of this plant in the Journal of 
the Straits branch of the Royal Asiatic Society, No. xxiv, 
pp. 170-2- (dated 1891), under the name of Petrosavia y thinking 
at the time it was identical with the plant described under 
this name by Beccari. Beccari’s plant, however, though in 
many respects resembling this, is in some most important 
details very distinct, as shown in the preceding remarks by 
Mr. Groom. It is very difficult to refer Protolirion to any 
order ; possibly it is most nearly allied to Triurideae.
