to Botany. Sufficient space is wanting to admit of its pos- 
sessing that fiilness of detail, without which such an In- 
troduction would he worse than useless. Henfrey's Rudi- 
ments of Botany, ed. 2, was written as a companion volume 
to this Manual, and is strongly recommended to persons 
commencing the study of Botany ; but they should after- 
wards make themselves acquainted with the contents of 
some more elaborate treatise, such as BaKour's Manual or 
Class-hooJr, or Henfrey's Elementary Course. 
It is hoped that those who use this book will favour the 
author with information of any (even the slightest) addi- 
tion, correction or alteration that may appear to be neces- 
sary, in order that it may be employed in the preparation 
of a future edition, as it is only through such assistance 
that the Flora of an extensive country can attain to even a 
moderate degree of perfection. 
In this book the term PhyUaries, introduced by Mr. 
Joseph Woods, is used for the parts in Compositce which 
were considered by Linnaeus as the leaves of a common 
calyx, and called by modem writers the bracts or scales of 
the involucre. Like many other botanical terms, it is chiefly 
useful in shortening and simplifying descriptions. 
Botanists have used the word Joint (articuliis) as signi- 
fying the point of union of two different parts, or the space 
hetween such points. Joining is here employed in the 
former of these senses ; and Joint is used as in common 
speech for the parts so joined.
