34 INTRODUCTION. 



V. Aeeangement of the Text and Abbeeviations used in the 



PEESENT WOEK. 



In the following pages the name of each Family or Order (for the two 

 words may be indiscriminately used) is given in English and in Latin. 

 The English name is always in two words, exclusive of the particle. 

 Where the first word is not the name of a genus also, it may be used alone 

 to designate the family by putting it in the plural, as Crucifers for the 

 Crtwifor family, Waterlilies tor the IVaterlily family. Where however it 

 is also the name of a genus, and it is wished to designate the family by 

 a single word, in order to avoid confusion, either the Latin name must be 

 taken, or it must be Anglicized by some of the modes which have been pro- 

 posed, such as substitutmg the termmations ids for idem, and anths or ads 

 for acecB, as : Orchids for Orchidece, Ranunculanths or Ranunculads for 

 RanunculacefB. 



After the name of the family, the first paragraph, in large type, is the 

 character of the family ; the second, in ordinary type, contains remarks on 

 its geographical distribution and affinities. 



This is followed, in small type, by the analytical key of the British genera 

 belonging to the Order, as above explained, p. 30 ; and short memoranda are 

 occasionally subjoined on commonly cultivated plants belonging to exotic 

 genera. 



Each genus commences vrith the name, in English on the left, in Latin 

 on the right. Where there is no English name suitable for the genus, the 

 Latin one is repeated, as it must in that case be used as Enghsh. 



Then foUow the genario character, a paragraph of remarks, an analytical 

 key of species, and occasional memoranda on exotic cultivated species, all in 

 the same form as in the case of the families. 



Each species commences with the name, consisting, both in English and 

 in Latin, of two words. In English, the first word indicates the species, the 

 second the genus; but both vaxxst be used in naming the plant, excepting in 

 a few cases where the firtt word is a popular name apphed to no other plant; 

 the generic name may then, for ordinary purposes, be dispensed witli, as : 

 Charlock Brassica may be called simply Charlock. In Latin, the first word 

 indicates the genus, the second the species ; and the name is generally followed 

 by the indication, in abbreviation, of the botanist who fii-st fiied the name 

 for the species in question. In these abbreviations, Linn, stands for Linno'us; 

 £r. for Robert Brown; DC. for Be Candolle ; Sm. for Sir James Smith. 

 Other names are usually abbreviated by giving the first syllable with the first 

 letter of the second syllable, as Hook, for Hooker. 



After the name is a parenthesis, in which reference is given to the plate 

 in Smith and Sowerby's 'EngUsh Botany ' where the species is figured, and to 

 any name, different from the one here adopted, under which the species may 

 be described in the English Botany, in Hooker and Arnott's 'British Flora,' 

 or in Babington's ' Manual of British Botany.' Thus, under the Lesser 

 Thalictrum, "{Ewg. Bot. 1. 11 ; T. majus, Eng. Bot. t. 611 ; and T.Jiexwosum,
