34.2 111. POLYGONACER. 
Tropical and subtropical Asia, Africa, America, and Australia, 
and extending into some temperate regions. 
A specimen from the summit of mount Omei has relatively 
large densely-clustered flowers, and the tomentum on the under 
surface of the leaves is buff-coloured. 
Var. cristatum, Hemsl. ; luxurians, multicaulis, foliis minori- 
bus minus pubescentibus, floribus densissime spicato-paniculatis. 
Formosa: without locality (Oldham, 434 !). Herb. Kew. 
The very large condensed inflorescence of these specimens and 
the relatively small leaves at first suggest an affinity with P. al- 
pinum, All., and P. polystachyum, Wall.; but an examination of 
ihe nutlet reveals the true relationship.
