Gencni" wliicli follows is siiiiihir to, but more toflitiical than that f»f 

 the other, more elementary book; and the names of the tribes or 

 natural groups of genera (;'>07) are inserted. The steps of analysis 

 bring the student to the Tribe III. llANUNCULKyE, and under it to 

 the genus Kanl'NCUI.is. TIh^ numlx-r pn^fixed to the name enables 

 the ^tudent to turn lorwaid and fnid the genus, p. 40. The name, 

 seientKic and popular, is here followed by a lull generic eharaetcr 

 (.")20). The primary sections here have names : the plant under 

 examination belongs to "§ 2. Ranunculus proper"; and tlienee 

 is to be traced, through the subdivisions *, -»— h— -t— -i— , ++ ++, to 

 the ultimate subdivision i., under which, through a eompari>on of 

 characters, the student reaches the species R. bulbosus, L. 



o40. The L. at the end of the name is the recognized abbrevia- 

 tion of the name of Liiuiaius, the botanist who gave it. Then come 

 the common or English names ; then the specific character ; after this, 

 the station where the plant grows, and the region in which it occurs. 

 This is followed by the time of blossoming (from May to July ); 

 and then by some general descriptive remarks. The expression 

 *• Nat. fiom Eu." means that the species is a miUiralizecl emigrant 

 from Europe, and is not original to this country. But all these 

 details are duly explained in the Preface to the Manual, which the 

 student who uses that work will need to study.

.") II. liKtMNMiis should not be discouraged by the slow jirogress 

 they niu<t needs make in the first trials. By perseverance the vari- 

 ous diirurulties will soon be overcome, and each successful analysis 

 will facilitate* the next. Not only will a s<M*oiid species of the same 

 genus be known at a glance, but eoMimonly a second genus of the 

 same order will i)e recognizecl as a relative at sight, by the family 

 likeness. Or if the family likeness is not detected at the first view, 

 it will be seen as the characters of the plant are studied out.
