Shrubs with opp. leaves ; the buds arise closely protected by the leaf- 
bases through which in many sp. they have to break. The firs, are 
conspicuous and strongly scented. Sta. 20 — 40 ; ovary inferior, usu- 
ally 4-loc. Fir. protogynous. Several sp. are grown in shrubberies 
under the name Syringa.

shrubs, usually climbing and often epiphytic, with both clasping roots 
and aerial roots reaching the soil (see order). The latter sometimes

development of the portions between the ribs, and not to a process 
such as occurs in Monstera (y.z/.). Monoecious.
