herbaceous plants, a class entitled to much more attention than 
they often receive: — 
D. Ajacis , so called from a fancied resemblance in the mark¬ 
ings of the flowers to the letters AJA. It is an annual, 
producing pink blossoms. A native of Switzerland, whence 
it was brought in 1573, and is by some considered to be a 
variety of the species Consolida. 
JD. amcenum. A perennial with pale blue flowers, introduced 
from Siberia in 1818 ; it is of rather rambling habit. 
D. azureum . A perennial with beautiful bright blue flowers; 
it is a tall growing species, well suited for the centre of a 
group, and coming from Carolina, is somewhat tender. 
JD. Barlowii. A beautiful hybrid, with shaded flowers of an 
intense dark blue; should be in every collection. 
JD. Consolida . An indigenous annual, producing flowers of 
several shades of blue, but always beautiful, and well de¬ 
serving a place in every garden. 
D. Consolida pleno. A double variety of the above, bearing 
blue flowers occasionally interspersed with red; it is com¬ 
paratively tender. 
Z>. chinense. A perennial from China, introduced in 1818 ; 
the flowers are of an intense deep blue, and being of dwarf 
habit, the plant is a general favourite. As already men¬ 
tioned, there are several varieties of this species. 
JD. eleganspleno. A double seminal variety, perfectly hardy; 
the flowers are dark blue. 
JD. grandifiorum. A perennial from Siberia; its flowers are 
very dark blue. There are three varieties of this species 
besides that now figured: the album , a very good white; 
pallidum , having pale blue flowers; and a double one: they 
are all beautiful. 
JD. peregrinum and its varieties are too well known to require 
any description. 
JD. Requienii is a curious biennial, with pale blue, from the 
island of Majorca, whence it was brought in 1824. 
Besides these there are a few others remarkable for their 
colours, which are at present very scarce: these are ochroleu- 
cum , yellowish white, pseudo-peregrinum , red, and revolutum , 
pale blue; all of them are hardy herbaceous perennials. In 
fact, though a few of those mentioned in the foregoing remarks
