obsolete scales, and large leafy toothed bracts. A native of 
China, and too tender for any but the most favourable localities 
in this country. 
Arthrotdxis is a small genus of Australasian evergreen 
dicecious shrubs with small scale-like leaves and small glo- 
bular cones of imbricated scales with from 3 to 5 carpels under 
each scale. None of the species are hardy enough to with- 
stand our ordinary winters. 
5. SCIADOPITYS. 
So far as at present known, this is a monotypic genus. 
Leaves linear, whorled. Male cones small, sessile, terminal. 
Female cones ultimately pedunculate ; scales broad, rounded, 
entire, coriaceous, persistent; bract short, broad. Seeds 
winged, 7 to 9 under each scale. The name is a compound 
of oxtas ddos a parasol, and wirvs, a Pine-tree, in allusion to 
the disposition of the leaves resembling the framework of an 
umbrella.

terminal, with dense ligneous deciduous scales, each bearing a 
solitary seed. <A genus of few species found in South America 
and Australasia. The generic name is from Araucanos, the name 
of a tribe of people in Chili whose principal article of diet is 
furnished by the large nuts of A. ambricata.
