[part it. 
though chiefly developed in temperate Australia, extend into 
the tropical or sub-tropical portions of it, and may well have 
reached New Zealand by the same route. 
On the other hand we find but few New Zealand genera 
certainly derived from Australia which are especially temperate, 
and it may be as well to give a list of such as do occur with a 
few remarks. They are sixteen in number, as follows : — 
!• Pennantia (1 sp.). This genus has a species in Norfolk Island, indi- 
cating perhaps its former extension to the north-west. 
2. Pomaderris (3 sp.). Two species are common to Temperate Australia 
and New Zealand, indicating recent trans-oceanic migration. 
3. Quintinia (2 sp.). This genus has winged seeds facilitating migration. 
4. Olearia (20 sp.). Seeds with pappus. 
5. Craspedia (2 sp.). Seeds with pappus. Alpine ; identical with Australian 
species, and therefore of comparatively recent introduction. 
6. Celmisia (25 sp.). Seeds with pappus. Only three Australian species, 
two of which are identical with New Zealand forms, probably 
therefore derived from New Zealand. 
7. Ozothamnus (5 sp.). Seeds with pappus. 
8. Epacris (4 sp.). Minute seeds. Some species are sub-tropical, and 
they are all found in the northern (warmer) island of New Zealand. 
9. Archeria (2 sp.). Minute seeds. Tasmania and New Zealand only. 
14. Alternanthera. Tropical Australia, India, and S. America. 
15. Tretr anther a. Tropical Australia, Tropics. 
16. Santalum. Tropical and Sub-tropical Australia, Pacific, Ma 1 ay Islands. 
17. Carumhium. Tropical and Sub-tropical Australia, Pacific Islands. 
18. Elatostemma. Sub-tropical Australia, Asia, Pacific Ialands. 
19. Peperomia. Tropical and Sub-tropical Australia, Tropics. 
20. Piper. Tropical and Sub-tropical Australia, Tropics. 
21. Dacrydium. Tasmania, Malay, and Pacific Islands. 
22. Dammara. Tropical Australia, Malay, and Pacific Islands. 
23. Dendrobium. Tropical Australia, Eastern Tropics. 
24. Bolbophyllum. Tropical and Sub-tropical Australia, Tropics. 
25. Sarcochilus. Tropical and Sub-tropical Australia, Fiji, and Malay 
Islands. 
26. Freycinetia. Tropical Australia, Tropical Asia. 
27. Cordyline. Tropical Australia, Pacific Islands. 
28. Dianella. Australia, India, Madagascar, Pacific Islands. 
29. Cyperus. Australia, Tropical regions mainly. 
30. Fimbristylis. Tropical Australia, Tropical regions. 
31. Paspalum. Tropical and Sub-tropical grasses. 
32. Isachne. Tropical and Sub-tropical grasses.
