PART VI. ORNAMENTAL GARDENING. 321 



Some form a broad, flat, and apparently solid mass upon the sur- 

 face, as the cerastiitm, saiifraga, &c; others a more loose, but 

 still a broad mass, as the trollius, convalaria, primula, Sec. From 

 this solid mass some send out high flower stems, as the asphode- 

 lus; and others conceal these among the flowers, as the epiden- 

 dron. With respect to modes of growth, some send out branches 

 from a principal stem like a tree, as the car dm; others send all 

 their stems from the root, as the mentha, Sec. There is a me- 

 dium between these two extremes in the astrantia ; and both 

 modes are united in the scandex. Some plants always creep 

 upon the surface, as the ajuga ; some constantly attach them- 

 selves to others by tendrils, as the pisum; some again attach 

 themselves by twining round other bodies, as the convolvulus, 

 Sec. With respect to the flowers of plants, their form, colour, 

 and time of flowering, are endless; and no discrimination ei- 

 ther in the characteristics of general form, or of the flowers, can 

 be of much use to those who are not botanically and practi- 

 cally acquainted with them. Such will find their memory re- 

 freshed by the occasional use of Don's Hortus Cantabrigiensis, 

 and Stillingfleet's Catalogue of Flora. 



4. Annual flowers are equally various with such as are her- 

 baceous or perennial. Their culture is well known. They are 

 highly beautiful, and peculiarly adapted for parterres or flower 

 gardens, as being removed every year.
