are thyrsiflore. 
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, f 
an elegant species. 
620. Cean. microphylus Mx. E. &c. Shrub- m 
by much branched, quite smooth, branches di- J 
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. serpyllxfolxus Nut. Eat. De- 
cumbent bushy, branches filiform, leaves mi- 
nute nearly smooth elliptic 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 EVONYMXJS. 
Without giving a complete monograph of 
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 
petals, and the fruit is peculiar, it belongs to a 
peculiar family (with Tobira) near to the Ce- 
lastrides. Tobira differs by 6 stamens and 
caps 31oc. polysperm.
