Euphorbia humistrata Engelm. ; A. Gray, Man. Ed. 2. 386. 1856. 



The known geographic ranges of the above species has lately 

 been greatly extended southward by collections from Mississippi 

 Professors. Tracy and Earle found it on Horn Island (2886) 

 and at Biloxi (2913). 



The name Gatesia cannot be applied to the Acanthaceous genus 

 of the southern United States, with which it has lately been asso- 

 ciated, having previously been used for an entirely different plant. 

 I take pleasure in using in this connection the name of Prof. W. 

 S. Yeates, State Geologist of Georgia, for while on his survey I 

 first met this rare and peculiar species along the Flint river, in 

 southwestern Georgia. Previousl)^ it had not been known to oc- 

 cur east of Alabama.

Vibiirmtm pnmifoliuin is said to grow as far south as Missis- 

 sippi and Florida, but during all my travels in the Southeast I have 

 not met with the species. Viburnum rufotomenioswn seems to re- 

 place our common plum-leaved Viburnum in the Southern States. 

 The most southern station at which I have collected V. pninifolium 

 is Salisbury, North Carolina.
