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, Bigelow, 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 . 
uzureus 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 Fhylici- 
des with Phylica, Bumalda, Brunia, Hovenia, 
Colletia, '<fcc, 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. Pomaderis , and the 
African must form niy G. Hypoma , see fl. tel.
