The Spirxa here figured differs much in habit from its 
congeners, and is remarkable for emitting an odour of 
creosote. It was discovered in West Arizona, in 1853, 
by Dr. J. M. Bigelow, and has since been collected on 
the Sierra Nevada of California, at ten thousand feet 
elevation, in latitude 36° 30’ N., in 8. Utah, and as far 
north as W. Wyoming Territory, but does not appear to 
extend further north on the Sierra Nevada, or south along 
the Rocky Mountains of Colorado than the positions 
here given. Its resemblance in foliage to Chamebatia 
foliosa, Benth., t. 5171, also a native of California, is very 
striking. 
The specimen of S. millefolium here figured, which is 
from a bush three feet high, was raised in the Royal 
Botanic Gardens, Kew, from seeds sent by Professor 
DecemBkR Ist, 1901.
