DEDICATION. 
encouragement I cannot adequately acknowledge, though I am fully sensible, from one so eminent for his 
attainments and labours, of the honour conferred upon me by it. 
In my excellent friend Mr. Carey I ever found the fullest sympathy, and I had hoped to have been 
guided by his cautious judgment. But, like our friend Tuckerman, though from very opposite causes, he has 
been turned aside from his early pursuits. 
I say nothing of the difficulties of my undertaking, undoubtedly increased by my inadequacy to meet 
them successfully. I might lay claim to some allowance by alluding to the imperfect success of several 
eminent names. I know of but one remarkable exception, and that is of the inimitable Schkuhr, whose 
£ Riedgraser,’ from its truthfulness, simple beauty, and unpretending form, is without a rival in Botanical 
literature. 
A few of the figures are by Miss Rees, a pupil of the Kensington School of Design, and all the litho¬ 
graphic copies are by her. Three of the engravings are by Mr. Castle, of London; all the rest were made 
in Paris.
