SABBATIA BRACHIATA Ell. Bot. S.C. & Ga. 1: 284. 1817. 
It is quite possible that Michaux had this plant in mind as the 
type of his Chironia angularis var. angustifolia ;* the description of 
the latter is too meagre, however, to warrant a change inthe name 
without further research. 
NERIUM OLEANDER L. Sp. Pl. 209. 1753. 
Abundant on the beaches along the coast as an escape from 
gardens and in many places apparently spontaneous. 
ASCLEPIAS VERTICILLATA LINEARIS (Scheele). 
Asclepias linearis Scheele, Linn. 21: 758. 1848. 
Asclepias verticillata var. subverticillata A. Gray, Proc. Am. 
Acad..23: 71. 1870. 
Only two specimens of this variety were obtained (no. 1006, 
Ocean Springs). It is distinguishable from the type by the oppo- 
site rather than verticillate leaves. 
ASCLEPIAS AMPLEXICAULIS Michx. 
Abundant in the sand on Deer Island, off the coast of Biloxi. 
(No. 1186). Walter’s characterization of his A. humistrata as 
‘‘ floribus rubris” leads me to doubt the propriety of taking up his 
name for the species. 
LEONOTIS NEPETAEFOLIA R. Br. 
A tropical African plant sparingly adventive throughout the 
South, but in the coast region of Mississippi a common weed. 
MESOSPHAERUM RUGOSUM (L.). 
Clinopodium rugosum L.. Sp. Pl. 588. 1753. 
Hyptis radiata Willd. Sp. Pl. 3: 84. 1800. 
This labiate is common in southern Mississippi. The genus 
Mesosphaerum, founded by Patrick Browne in 1756, has thirty 
years’ priority over Hypzis of Jacquin. 
Teucrium Nasu Kearney, Bull. Torr. Club, 21: 484. 1894. 
My specimens of this handsome Zeucrium, collected on Prof. 
Tracy’s grounds near Biloxi (no. 1075), exactly match Mr. 
Kearney’s type from Florida. 
* Fl. Bor. Am, 1: 146. 1803.
