|Weinmannia: Kamahi & Towhai|
Weinmannia racemosa Kamahi
Weinmannia sylvicola Towhai
The seed of this genus is light and is produced in profusion in late autumn. It germinates readily. Towhai is a plant of the north and can be found in regenerating bush or is often common on clay banks on the side of the road.
Kamahi is found south of the Bombay Hills and is very common in the South Island, where it can form almost entire communities.
The flowers are sweet scented and produced in profusion in November and December. Most of the capsules ripen and dehisce by March, and by the end of April little seed remains on the tree. Measuring 1.5 X 0.4mm and fitted with small tufts of hair up to 1mm long and weighing about 0.1 mg, the seeds are well adapted for wind dispersal. The seeds can germinate 21 days after dispersal. The readiness with which these species germinate plus the large number of seeds produced ensures the species success in many environments.
