terminal flowers” (F. F. and G. Bot. p. 76). Bentham and 
Hooker characterize the genus Camellia as having “flores axil- 
Jares” (Gen. Plant., Vol. L, p. 187), and De Candolle makes 
exactly the same statement (Prod., Vol. L, p. 529). This contra- 
diction led me to examine closely the inflorescence of a consider-

one terminal leaf-bud and one leaf-bud in each axil. Each of 
these leaf-buds is or may be accompanied by two flower-buds,
