Mr. Woods on the Britixh Species of Rosa. 167 



rf it were as usual. In a regularly-formed calyx they are always 

 very narrow at the point of junction, and go off at a considerable 

 angle; and when they take their commencement from a wido 

 base, or lie nearly parallel to the line of the leafit when the flower 

 is open, the calyx must be rejected as a monster. On this sub- 

 ject some further observations will be found in the course of 

 this introduction. Ihis character (of a simple calyx), like all 

 others in the genus, must be determined with caution ; as even in 

 some of those Roses whose calyx is generally simple, a small offset 

 may sometimes be observed, even putting monstrosities out of the 

 question. Another circumstance to be attended to is, that the 

 proper offset or pinna always occurs before the contraction of the- 

 calyx leafit at the point of the flower; after that contraction 

 many Hoses have a strong tendency to produce more or less of a^ 

 leaf. 



The five leafits of the calyx of a Rose, united before the expan- 

 sion of the flowers, present five lines of junction, each of which 

 in the compound calyx is furnished with a row of offsets; two of- 

 the leaves having pinnae on each side, one on one side only, andi 

 the remaining two are uniformly entire. 



" Quinque sumus fratrea, sub eodem tempore nati, - 

 Bini barbati, bini sine crine creati, 

 Quintus habet barbam sed tantum dimidiatam." 



This arrangement I express by the term compound : in the suh' 

 aimple calyx every flower offers one or more of these offsets, but 

 the whole provision is never found in any one. 



In all Roses these calyx leafits are liable to become monstrous 

 two ways: sometimes one or two, or sometimes even the whole 

 number will grow out into leaves {folia), and sometimes the off- 

 sets are entirely wanting even in species Avhere they usually are 



the
