MARSILEACEAE 
Marsilea vestita Hook. & Grev. ssp. vestita [S: M. mucronata A. 
Braun] (Missouri materials attributed to this taxon are 
referrable to M. quadrifolia L.) (Johnson, 1985), p. 18 
OLEACEAE 
Ligustrum vulgare L. (although this species was fully treated and 
illustrated by S: on the basis of its potential presence 
in Missouri, it was stated to be excluded from the flora 
based on the lack of collections from noncultivated 
plants; although it still seems likely that this species 
will be found in the state, it has yet to be collected 
from any spontaneous population), p. 1183 
ONAGRACEAE 
Gaura biennis L. (note that Raven and Gregory (1972) 
| redetermined all Missouri collections attributed to this 
| species as G. longiflora Spach; G. biennis is closely 
) related to this species and occurs in adjacent Illinois; 
although this taxon may eventually be located in 
| northeastern Missouri, for the present it must be 
| excluded from the state’s flora), p. 1107 _ 
Oenothera kunthiana (Spach) Munz (the single collection upon 
which S: based the report of this southwestern species 
in Missouri was misidentified and has been redeter- 
mined as Oenothera speciosa Nutt. by Warren L. 
Wagner, Smithsonian Institution), p. 1105
