tals white, whence my name, since all the sp. 

 are thyrsifiore. 



619. Cean. azureus Desf. ic. 232. Lod. cab. 

 110, Edw. b. reg. 291. Dec. Shrubby pubescent 

 leaves ovatoblong acute rough serrate, beneath 

 tomentose, panicle thyrsoidal, base foliose, flow- 

 ers blue — in Mexico, New Mexico and Texas, 

 an elegant species. 



620. Cean. microphylus Mx. E. &c. Shrub- 

 by much branched, quite smooth, branches di- 

 vergent, leaves fasciculate minute oboval or 

 rounded obtuse trinerve, racemes terminal co- 

 rymbose — Florida, Georgia, Alabama, a very 

 peculiar sp. habit unlike the others, but like the 

 next, flowers vernal as in the Southern species. 



621. Cean. serpyllifolius Nut. Eat. De- 

 cumbent bushy, branches filiform, leaves mi- 

 nute nearly smooth elUptic ovate obtuse serru- 

 late, petiols and nerves strigose, panicles axill- 

 ary peduncled pauciflore glomerate — Florida, 

 very small, habit of thyme like the last, and 

 probably both ought to form a subgenus. Is it 

 only a var. of it ? Elliot has blended both ; disc 

 by Dr. Baldwin near St. Mary. 



Genus EVONYMUS.

 our sp. I can greatly increase them having 4 

 or 5 new ones to describe. They form 3 sub- 

 genera with opposite leaves and axillary pedun- 

 cles. This G. had been wrongly united to 

 Rhamnides, since the stamens are alternate to

 peculiar family (with Tobira) near to the Ce- 

 lastrides. Tobira differs by 6 stamens and 

 caps 31oc. polysperm.
