The Chinese Thorn here figured is very closely allied to 
the European Everlasting Thorn and to its Himalayan 
representative the White Thorn of Nepal. A perplexing 
divergence of view has prevailed as to the taxonomic 
position and status of these three Thorns. The Everlasting 
Thorn or Buisson Ardent which, in 1753, Linnaeus named 
Mespilus Pyracantha, was, forty years later, treated by 
Medik as a Crataegus and, after a similar lapse of time, 
referred by Spach to Cotoneaster. The Nepalese White 
Thorn was in the first instance referred, in 1814, to Crataegus, 
by Roxburgh, as C. erenulata, but was treated by D. Don in 
1825 as a Mespilus, and was only transferred, by Koch, to 
Cotoneaster as recently as 1869. The subject of our illus- 
tration, which was discovered by Delavay in Yunnan in 
1882, was in the first instance referred by Franchet in 1889 
to Cotoneaster as C. angustifolia. The agnomen “ Pyra-
