In submitting the following Inprxes to our Readers, we 
thankfully acknowledge the assistance we have received from 
Mr. Harrop, of Manchester, who kindly transmitted to us a copious 
index, compiled for his own use, containing not only the names of 
the plants, as given in the Botanical Magazine, but of their syno- 
nyms also. By the aid of this index we have been enabled to 
render this part of our labours more complete than it would have 
otherwise been. We have, however, thought it would add more 
to bulk than to usefulness, to insert the synonyms of the older 
authors, prior to Linneus’s happy invention of trivial names. 
It was from Mr. Harnor’s suggestion, that we have been 
induced to add the adopted names to the synonyms ; which will not 
only ‘save the trouble of referring to the work itself to find its 
approved appellation, but even to those who do not possess the 
Botanical Magazine, may be found useful, especially to purchasers 
of plants, by preventing their giving orders for the same under 
different names, an inconvenience, which we have been assured 
frequently occurs, more especially in the country. 
That we might increase the bulk of the index as little as possible, 
we have placed the adopted name under the synonym, prefixing the 
word est, instead of inserting it ina different column. By so doing, 
however, we suspect that at first sight, our index will appear 
somewhat confused, but the difficulty will be easily got over by 
observing, that the line will always lead the eye to the true alpha- 
betical arrangement of the species, the intervening names having 
no line prefixed. The synonyms are printed in Italics ; and where 
the approved name is different from the one under which the plant 
was published in the Magazine, the latter name is inserted beneath, 
between brackets. In the same manner, when the name adopted
