and some white ; flowers in whorls, terminale, or soli- 

 tary. They grow best in a light rich soil. G. lutea, G. 

 purpurea, G. septemfida. G. acaulis is a pretty dwarf 

 growing species, and often used as edgings in flower 

 compartments; the flower dark and light blue; interior 

 of the corolla spotted; has a succession of flower from 

 April to June. We have no doubt of it succeeding in 

 our gardens, but not being plentiful, it has not been 

 perfectly tried. A few years will exhibit it in abun- 

 dance. G. imbricata and G. conferta. They are all 

 fine exotics, but many of them may give place to our 

 native species, such as G. Catesbcei, ; G. ochroleuca ; G. 

 incarnata; with several others, and G. crinata, which 

 is a biennial, and finely fringed ; colour light blue. 



Geum. There are only two species that are worth 

 cultivation, viz. G. quellyon, once G. coccineum; and 

 G. hybridum. G. urbdnum is sometimes cultivated for 

 its roots, which, when chewed, sweeten the breath. 

 They are all of easy culture. G. quellyon flowers from 

 May to October, aud is a very desirable small plant for 

 the borders, and much esteemed in Europe. 



Hemerocdllis, Day Lily; two species, H.fulva and H. 

 graminea, flower well, and are remarkable among the 

 border flowers for their large yellow or copper colour- 

 ed corollas, some of them about six inches diameter ; 

 bloom from May to July, and will grow in almost any 

 soil. There is a plant known in our gardens as H. 

 carulea, which is Funkia ccerulea, and has a campanu- 

 late corolla, with a cylindrical tube ; flowers in spikes ; 

 leaves ovate, accuminate. 



Hibiscus. There are several herbaceous species
