FLORA OF MISSOURI.

The following catalogue is, I believe, the first publication of any 

 list of the plants of the State, excepting a '•Partial Catalogue of the 

 Phntsof Illinois and Missouri," published by Mr. Geyer about 1842 

 which has long been out of print. The present catalogue was com- 

 menced more than five years ago, but the press of other important 

 work has prevented its earlier publication. Even now there are doubt- 

 less many species which are not iiiclu led as there are some sections of 

 the State which I have been unable to vi>it, and from which I have 

 found it impossible to obtain lists. The counties along the central 

 part of the Southern boundary, and the ex'reme Northern and North- 

 eastern portions of the State have not yet been carefully studied. 



The sources from which this catalogue has been made are; the 

 herbarium of the State University which includes valuable collections 

 made by the Stat^ Geological Survey, Prof. Swallow, Dr. Pech of 

 Louisiana, Mr. Geyer and Dr Engelmann of St. Louis and others ; the 

 "Flora of Jackson County "■ and extensive notes Irom Frank Bush of 

 Independence; notes and specimens from Prof. G. C. Broadhead of 

 Pleasant Hill, Geo. VV. Letterman of Allenton ; Mrs McCluney of Se- 

 dalia, and many others. I am indebted to Prof. Trelease of Washing- 

 ton Ufiiveri-ity for access to the Riehl collection of Missouri plants, and 

 to Mr. B. T. Galloway of Cjlumbi^, who has done the entire work of 

 preparing the list of grasses, and has furnished notes upon many other 

 plants. Free use has been made of the various published works of Dr. 

 Gray, and the government reports of King and Wheeler. During the 

 past twelve years 1 have visited many parts of the Stat;e, and have pre- 

 served a careful record of plants observed in the different localities. 

 Nearly every plant named in the catalogue has been carefully exam- 

 ined by myself, and doubtful specimens have been referred to Dr. 

 Gray, Vasey or other recognized authorities for verification. I have
