Childing Marygold, and Hawkweed. See PI. 12. Fig. 3. 
Which reprefents a Hawkvveed railed to extreme Luxuriance by Mr. 
Perfect, Groundworker atPoMFRET in Yorkshire, 1754. 
The Bites of Infers alfo will occahon mimic Flowers, and Fruit. 
The Rose Willow is an Inftance of the former; and the Galls fa- 
miliarly lliew the latter. The Angular excrefcence of the Willow 
refembling the Flower of a Rofe, and thence diftinguidied by a pe- 
culiar name, is figured in PI. 12. Fig. 4. The old Authors fuppofed 
it was a peculiar kind of Willow which bore Rofes ; but it is a mere 
accidental excrefcence of the common Willow. I faw fome hundreds 
of them a few years fince on the WTlows about Bug den ; and this 
which is here defigned from nature, is from a very fair one taken off 
a Willow near the feat of Sir Roger Hill of Denham. 
The common Galls we ufe for Ink are excrefcences of the Oak, 
produced in the very lame manner as this of the Willow, by the 
wound of an Infedt ; and the fame tree affords many other kinds. 
That which is reprefented, PI. i2. Fig. 5. is what we call the Oak 
Apple. It is figured from a very fair one gathered on Iver Heath in 
Buckinghamshire. 
II. Of LEAVES. 
Leaves in their firfi; Inffance of Luxuriance become curled and 
elevated in waves, and folds and ridges, varioully, and often elegantly 
turned; as in the curled red Cabbage. See PI. 12. Fig. 6. 
In the fecond or mofl extreme degree their Surface riles on the Dilk 
in bubbles, as well as at the Edge in waves ; and they become then 
what we call Folia biillata ; bubbled Leaves. Of this the bubbly 
Lettuce is an elegant inftance. PI. 12. Fig. 7. 
This is ov/ing to abundant Culture, and Luxuriant Nourilhment : 
and from thefe few plain Inflances may be underftood all that un- 
natural elegance which Plants alTume from Culture.
