xiii, c, 6 Swingle : Merillia, a new Rutaceous Genus 341 
nosum (Blanco) Swingle, it may be used as a stock upon which 
to graft the commonly cultivated species of Citrus. Mr. Ridley 
has called attention to the beauty of the wood of the katinga 
and Mr. F. G. Penney secured enough of this wood in southern 
Siam to make a much-admired set of furniture. The flowers are 
very large and it is possible that this species would be worthy 
of cultivation as an ornamental plant. At any rate it deserves 
a place in every tropical and subtropical botanic garden and 
arboretum.
