THE COTTAGE GARDENER. 
divided into five lobes, hence its specific name; growing 
only ton inches high. Increased by dividing the creep¬ 
ing root-stock. 
A. polyodon (Many-toothed). — Another handsome 
Fern from New Zealand; fronds pinnated, lance¬ 
shaped, growing two feet long; pinnae nearly square, 
with long stems; each leaf is divided into segments, 
and each segment has two divisions or teeth, hence 
its name—Manv-tootheu ; stems scaly. Increased by 
division. 
The remainder of greenhouse AspUniums arc— A.prce- 
morsatn (Jagged-pointed). A. pubescens (Downy), and 
A. umbras urn (Shade-loving); all worthy of cultivation.

EARLY-FLOWERING BORDER PLANTS. 
(Continued from ‘page 438.) 
DAL1BARDIA. 
This is a commemorative name in honor of M. 
i Dalibard, a French botanist. The genus has only one 
i species, and it must be grown in a dry south border, or 
I on rockwork facing the south. 
D. viol.eoides (Violet-like).—A pretty white-blossomed 
plant, growing six inches high, flowering in May. From 
North America. 
DELPHINIUM.—LARKSPUR. 
This well-known tribe of hardy perennial flowers are 
generally great favourites in every garden. I am glad 
to record a few that flower in May. The name is derived 
from delpldn , a dolphin; the spur or heel of the flower 
beiug supposed to resemble the bead of that fish. 
D. cheilanthum (Lip-flowered). — From Siberia; a 
charming plant, with deep blue flowers, appearing in 
May, and growing two feet high. Increased by seeds 
and by division. 
D. flexuosum (Zig-zag).—Lately introduced from the 
Caucasian mountains; colour blue; height two feet, 
and flowers in May. Increased by division. 
I). intermedium laxum (Loose-flowered).—A garden 
variety. 
D. INTERMEDIUM LEPTOSTACHYUM (Sloildei'-Spiked).— 
From the Pyrenees. These two are tall growers, reach¬ 
ing often from four to six feet high. Both have blue 
flowers, and appear early in the year, about the latter 
end of May. They require rich soil, and a warm, 
sheltered border. Increased by divisiou. 
DENTARIA.—TOOTIIWORT. 
A genus of plants, with very pretty flowers, but they 
are seldom seen in gardens ; why, it is difficult to say, 
unless it be that they have tuberous roots; and are planted 
in open borders, in dry soil, exposed to the full sun, 
which is sure to be fatal to them ; plant them, therefore, 
in shady, moist, situations, and they will thrive and 
flower well. The name is derived from the tooth-like 
roots. 
D. bulbifera (Bulb-producing).—Found, but rarely, 
in England; grows a foot high; bears purple flowers, 
in April. Increases by dividing the tuberous roots, and 
by seeds. 
D. diphylla (Two-leaved).—From North America; 
with white and purple flowers, in May; nine inches 
high. Increased by division. 
D. enneai’hylla (Nine-leaved).—From Austria; 
colour of the flowers pale yellow; a foot high ; appear¬ 
ing the latter end of April. Increased by division. 
D. glandulosa (Glanded).—From Hungary; flowering 
in May: colour light purple; a foot high; and increased 
by division. 
477 
D. maxima (Largest). — A rather tall species, from 
North America; two feet high; large purple flowers, 
appearing in May. Increased by seed and division. 
D. pinnata (Pinnated, or Winged).—From Switzerland; j 
growing a foot high ; with pale purple flowers, appearing j 
in April. 
The rest all flower in May, and, excepting the last, j 
which is white, have all purple flowers, and all grow j 
about a foot high. 
D polyphylla (Many-leaved).—Hungary. 
D. quinquefolia (Five-leaved).—Tauria. 
D. tenuifolia (Slender-leaved).—Siberia. 
D. trifolia (Three-leaved).—Hungary. 
DIANTHUS,—THE PINK. 
Liko Delphinium, this is a large genus; the greater 
part of the species flower in the summer months, and 
are, therefore, not within my prescribed limits; there 
are, however, one or two that flower early. 
D. dubiiis (Doubtful).—A garden production, flower¬ 
ing in May, with white and rose-coloured flowers. 
Increased by cuttings and layers. 
D. Fischeri (Dr. Fischer’s).—From Russia; with red 
flowers, appearing in May; and growing a foot high. 
Increased by cuttings in sand, under a hand-light, or by 
layers. 
D. polymorphus (Many-formed). — Native of the 
Crimea; flowering as early as March ; colour deep red; 
growing a foot high. Increased by cuttings and seeds. 
DIELYTRA. 
This is, comparatively speaking, a newly formed 
genus, and the name is very happy and appropriate. 
Derived from dig, twice, and elytron, a sheath ; the parts 
of fructification being sheathed or covered by the two 
sepals. They all flower early. 1 liavo seen D. spectabilis 
in flower, in the open air, as early as the middle of 
April. The species are all allied closely to Fumaria. 
D. bracteosa (Bractea)—A North American plant, 
with white flowers; growing a foot high. Increased by 
division as soon as it lias flowered, or very early in 
spring. 
D. Canadensis (Canadian).—White flowers; growing 
nine inches high. Increased by division. 
D. cucullaiua (Hooded).—White; nine inches high; 
native of North America. Increased by division. 
D. eximia (Choice).—This was formerly Fumaria 
eximia, and is a handsome hardy deciduous perennial; 
from North America; with pink flowers. Increases 
freely by division. 
D. Formosa (Handsome). — Excepting Spectabilis, 
this species is the handsomest in the genus, with pretty 
pink flowers, produced freely amongst the handsome 
Fern-like foliage; the flowers grow a foot high. Native 
of North America. Increased freely by division. 
D. speoiosa (Showy).—Fink flowers, growing a foot 
high. 
D. spectabilis (Remarkable).—This fine Chinese 
plant is perfectly hardy. I saw, this summer, in the 
gardens at Wilsick Hall, the seat of T. Walker, Esq., 
so far north as Yorkshire, a plant that bad stood out 
several winters in the open air, and had no protection. 
It was the largest plant of the kind I ever saw, measur¬ 
ing live feet high, and six feet diameter. It was the 
first week in July when I saw it, and had then many 
flowers upon it. The gardener, Mr. Robinson, an old 
friend of mine, assured me that six weeks previously 
it was a perfect blaze of flowers. This is one of the 
best plants Mr. Fortune lias introduced from China. It 
forces admirably, and flowers well in the greenhouse as 
early as February; but it is advisable to plaut such 
forced plants out in the open border to make a summer 
growth, then take them up about October, re-pot them 
in larger pots, and they will be much stronger and
