Tribe lll.—TAXE^. 



Some authors consider this tribe to be itself a natural order 

 distinct from Conifers. 



Flowers unisexual, mostly axillary, dioecious, i.e. male and 

 female flowers appearing on different plants. The male flower 

 consists of anthers on short pedicels inserted on all parts of the 

 axis. Filaments short, prolonged in a peltate or squamiform 

 connective, and bearing 2, 4, or 8 cells, which open longitudinally. 

 Female flowers naked, solitary, or rarely two under each bract. 

 Ovule solitary, erect, sessile on the centre of the disc. 



Fruit always monospermous, more or less drupaceous, ripen- 

 ing once or twice a year. Embryo with two cotyledons. 



Of the plants belonging to this tribe, the Taxus (of which 

 some authors have made two species, others eight, others again 

 only one) is spread through the temperate regions of the 

 Northern Hemisphere. Other genera are found in Japan, China, 

 Tasmania, New Zealand, and Borneo.
