rived from the supposition that their 
flowers turn to the sun. 
HEPAT1CA (Linn.) Nat. Ord. Ra- 
nunculacea. These pretty plants are es¬ 
teemed favorites in the flower-garden; 
they grow with freedom in good garden 
soil, and their beautiful blossoms pro¬ 
duced before the foliage in the early 
spring months, are then highly prized. 
II. acutiloba, single bine, H. triloba, 
single red, and its double variety, are 
most common; the double variety of the 
former and the white are yet rare. 
HESPE11IS (Linn.) Nat. Ord. Cru- 
cifera;. A genus of handsome, hardy, 
herbaceous plants, H. matronalis and its 
varieties are well known in gardens 
under the name of Lockets, these should 
be seasonally propagated by cuttings, as 
it is only the young plants which bloom 
well; slips from the lateral shoots should 
be taken off in summer and struck under 
a handglass; light rich soil suits them 
best. The annual and biennial species 
only require to be sown where they are 
desired to bloom. 
HIBISCUS (Linn.) Nat. Ord. Mal¬ 
vaceae. An extensive, beautiful, and va¬ 
ried genus of plants, found in nearly 
every part of the known world, includ¬ 
ing among its members forms of nearly 
every description, from the trees and 
shrubs of the tropics to the hardy herba¬ 
ceous plants of the temperate regions of 
the European continent. The stove 
species are equally varied even among 
themselves; some are dwarf bushes, 
others attain the stature of trees, here 
we have the persistent character of the 
latter, while some other kinds are only of 
annual duration, and this diversity extends 
through the entire group. All of them, 
however, delight in rich light soil, such as 
that afforded by a mixture of peat, loam, 
and rotten manure ; all are gross feeders, 
and, therefore, should have abundance of 
water while growing, with the full in¬ 
fluence of the sun, that they may properly 
elaborate their juices and be induced to 
flower freely. These points are the only 
essential ones in their management, and 
apply equally in the stove, the green¬ 
house, or the open air. The tropical 
species are the most numerous, and as 
only a selection can be grown in any 
ordinary establishment, we would re¬ 
commend the following for the stove: 
cethiopicus, a twiner, purple; borboni- 
cus , yellow; ferrugineus, scarlet; Lindlei, 
purple; mutabilis , white; Rosa-sinensis and 
its varieties; and splendens, crimson. Eor 
the greenhouse we should prefer Cameroni, 
yellow and rose; and C. falgens , yellow 
and crimson; divaricatus , sulphur; lilli- 
Jlorus, scarlet; and militaris, purple ; and 
for the open border perhaps syriacus and 
its varieties are all that are worth culti¬ 
vating. 
H1ERACIUM (Linn.) Nat. Ord. 
Composite. A large genus of free-flower¬ 
ing, handsome, herbaceous perennials, 
quite hardy, and well adapted for plant¬ 
ing among rockwork, or near the front of 
large groups of mixed plants ; the genus 
also contains a very beautiful annual 
suited for growing in masses; this is 
perhaps better known by the English 
name of the genus, Hawkweed. The 
flowers of nearly all the species are yel¬ 
low, several of them are indigenous, and 
common on banks and open heaths, but 
notwithstanding are well deserving the 
little attention necessary to keep them in 
the neat order requisite in the flower- 
garden. 
HIPPEASTRUM (Heebeet.) Nat. 
Or. Amaryllidacece. This may with jus¬ 
tice be termed the most noble and showy 
section of the family to which it belongs; 
the flowers are variously coloured, some 
species have them entirely crimson, while 
others are white, abundantly streaked 
with red or crimson. The plants require 
precisely the treatment of Amaryllis. 
HOUSTONIA (Linn.) Nat. Ord. 
Gentianacere. A small group of very 
pretty herbaceous plants, quite hardy, 
and well suited for ornamenting rock- 
work; they delight in peat soil and a 
clear sunny position. 
HOYEA (It. Beown.) Nat. Ord. Le- 
guminosai. Extensive and beautiful as is 
the order to which these plants belong, 
it can scarcely be said to include an in¬ 
dividual genus whose flowers will bear 
comparison with those of Hovea; they 
are of varied shades of blue and purple, 
and in every ease of the richest hues;
