Gynamblosis monanthogyna. Engelmannia Nuttalliana, Klotsch, 1. c. 

 Croton monanthogynum, Michx. Fl. 2, p. 215. C. ellipticum, Nutt. Gen. 2, p. 

 235, (excl. syn.;) Torr. in Ann. Lye. N. York, 2, p. 245. Main Fork of Red 

 River ; June 24. The Engelmannia of Klotsch, which is based on Croton ellip- 

 ticum of Nuttall, must give place to the earlier genus of the same name of Torr. 

 and Gray. I propose for it a manuscript name given to the plant many years 

 ago, when revising the Euphorbiacem of the United States. Klotsch is wrong 

 in referring Croton monanthogynum to Hendecandra maritima. In the young 

 specimens of Captain Marcy all the staminate flowers are 8-10 androus : and the 

 later flowers are not unfrequently hexandrous. The petals and sepals vary from 

 three to five.
