iy pate flower is compofed of four large petals: the pod is long, flender, flatted, formed of two 
valves, containing two cells, and terminated by a ftyle, which is fplit at the top: the cup is 
eompofed of four long, narrow leaves, and falls with the flower : the feeds are oval and flatted. 
Linnaus places this, with the reft of the /liguo/e plants, among the ¢etradynamia filiquofa: but he 
abolifhes its received name /eucoium, calling it cheiranthus. 
There is one fingular plant of this genus, the pod of which, inftead of terminating in two, has 
three points. Many have of late made of this a particular genus, under the name of gakenia; but 
Linnzus much more juftly refers it to the reft, not allowing this alone a fufficient diftin€tion for a 
new genus. 
The botanifts of late time have accounted it an honour to conftitute new genera ; and have there- 
fore fought the moft trivial marks for a diftinétion, which ought to be founded only on the greateft 
and moft obvious. 
The Arabians call the common yellow waljfower, cheiri ; but it is wrong from that to derive the 
name cheiranthus for the whole genus,

1. Common Wallflower. 
Leucoium luteum vulgare. 
The root is divided into a number of long, 
{traggling parts, each: furnifhed with numerous 
fibres. * ; 
The ftalk is round, firm, upright, hard, and 
very much branched. 
The leaves are long, narrow, and of a frefh, 
green; they have no footftalks ; they adhere by 
the bafe, and they are undivided at the edges. 
The flowers grow ina kind of fpikes at the 
top of the ftalks and branches; and they are 
large, yellow, and {weet fcented. 
The pods are long, flender, and whitifh: the 
‘feeds are flatted and fmall. 
It is common on old walls, and in fome places 
on rocks; and has thence, for its beauty and fra- 
grance, been introduced into gardens, where the 
flower, and indeed the whole plant, grow much 
larger than in the wild ftate. 
C. Bauhine calls it Leucoinm luteum vulgare ;' 
and mott others follow him. 
When carefully cultivated the flower ‘gets 
ftreaks of aredifh or deep orange colour; and at 
other times it is rendered large and full of leaves : 
thefe are the Dloody wall and the double wall of our 
gardeners. 
It were well if we could accufe none above the 
rank of gardeners with raifing thefe varieties into 
the imaginary place of fpecies; or if thefe were 
all fo treated. We fee more of them, and in 
confiderable writers. 
C. Bauhine defcribes, 1. one with ferrated 
Jeaves; 2. one with great flowers; 3. a great, |

double; and, 4. a leffer, double wal/fower: thefe 
are all varieties owing to culture; and thus of 
one plant are made five. : 
2. Sea Wallflower. 
Leucoium maritimum filiquis tricufpidatis. 
The root is long, flender, and furnifhed with 
| a few fibres, 
The ftalks are numerous, weak, and branched; 
they ftand but irregularly upright, and they are 
of a pale colour, and a little hairy. ; 
The leaves ftand irregularly, and are long, 
narrow, and deeply indented at the edges: they — 
grow without footftalks, and are fomewhat hairy, 
and their colour is a pale whitifh green. 
The flowers ftand at tLe tops of the ftalks and 
branches; and they are large and white. 
The feed-veffels are long, fomewhat’ thicker 
than in the common kind, and hairy; but what 
is very fingular in them is, that each terminates 
in three points, inftead of the two of the com, 
mon kind, 
The feeds are fmall, oval, and flatted. 
It is found on the coafts of Wales and Corn- 
wal; and flowers in July, ~ 
C. Bauhine calls it Leucoinm maritimum finuate 
folio. , ; 
We have this in fome gardens in its natural 
condition; and we fee it in others raifed to 4 
greater fize, and into varieties, called diftingt fpe- 
cies by fome, from culture, 
What we call ftock Julyfowers are of the fame 
genus with wallfowers, differing only as fpecies, 
thengh the diftin@tion be very evident,
