 118.); sometimes spicate and centripetal, with sessile flowers 

 (f. 116. f. 117.), which are as if they were somewhat immersed 

 in hollows in the branches ; but are sometimes produced in leafy 

 spikes at the tops of the branches.

 of the stamens being alternate with the petals, not opposite to 

 them, and in the flowers being pedicellate, not adnate to the 

 branches.

Cult. Tristania is a genus of fine-leaved trees or shrubs.

 sand; and cuttings, not too ripe, strike root readily if planted 

 in a pot of sand, and placed under a hand or bell-glass.
