I2 ENGELMANNIA PINNATIFIDA.—CUT-LEAVED ENGELMANN FLOWER. 
he is esteemed by the botanical world as its leading authority on 
American Oaks, Coniferous trees, Agaves, Yucca, Cuscuta, Juncus 
or the Rushes, Cactacez and many others. He is not a native 
of this country, but was born at Frankfort-on-the-Main, on the 
2d of February, 1809, so that he is now in his seventieth year, 
and is still actively engaged in his favorite study. He pub- 
lished his first botanical work in Germany; came to the United 
States in 1832, when but twenty years of age; and, two years later, 
settled in St. Louis, where he has ever since remained. No 
American botanist is more esteemed for his many virtues as well 
as for his work than Dr. Engelmann, and we are glad that he 
will be ever remembered in connection with this pretty flower. 
Nuttall, who collected this plant, thought it was a species of 
Silphium. No other species but the one we figure has been 
found, though a marked variety is noted in the account of Lind- 
heimer’s Texan plants. Dr. Torrey in the Axzals of the New 
York Lyceum, published in 1820, notices the species as having 
been collected by Dr. James on the Canadian river. Nuttall 
and Dr. Leavenworth are credited with collecting it on the Red 
river, in Arkansas; Drummond found it in Texas; and Marcy’s 
expedition in the Witchita mountains. 
For the opportunity of making our drawing we are indebted 
to the Bussey Institution, where it was growing under the care 
of Mr. Jackson Dawson, of the Arnold arboretum.
