VIEW OF THE GENUS CUPRESSUS. 351 
are tightly adherent (valvate), and the whole cone resembles 
that of a true Cypress rather than that of a Chamecyparis. 
In its wingless seeds it seems to bear the same relation to 
Cupressus that Biota does to Thuya, and furnishes another 
indication that Cupressus, Chamaecyparis, Thuya, and Biota have 
all descended, relatively recently, from the same stock.

Cones of Cupressus, sp., from Botteri. 
The cones collected by Botteri, just alluded to, have, in the 
dry state, their scales so widely separate that the cones resemble 
those of Tetraclinis articulata, and their peltate form is scarcely 
apparent. If, however, the cones be soaked in water, so as to 
restore the original form, a resemblance to Humboldt's thurifera 
becomes visible.
