in Eaton, nor any of the above shrubby Labiate. 



MONOGRAPH OF CEANOTHUS. 



This pretty and useful natural Genus de- 

 serves a complete examination, being now great- 

 ly increased in species: they are all small 

 shrubs, or bushes, but some are perennials. 

 Linneus had only one, Michaux, Bigelovv, Nut- 

 tal Hooker and myself have added many others, 

 altho' Eaton enumerates only 6. All have es- 

 tival white flowers in thyrsoid corymbs, but C. 

 azureus has blue flowers. Leaves alternate 

 with short petiols. Roots red and medical see 

 my Med. flora. This G. commonly united to 

 the Rhamnides, rather belongs to the Phylici- 

 des with Phylica, Bumalda, Brunia, Hovenia, 

 Coiletia, <Slc, having all fruits coccular as in 

 Euphorbides ; but the stamens are opposed to 

 petals and often inserted thereon. The Asiatic 

 and African sp. of this G. appear to form pecu- 

 liar genera, the asiatic form the G. Carpode- 

 tus, the Polynesian the G. Pornnderis, and the 

 African must form my G, Hypojim, see fl. tel.
