 number of constituent petals. So this is a kuid of ganiopetalous 

 corolla, which is open along one side nearly to the liase, and outspread.

like, only the marginal (or raij) co- 



' rollas are ligalate ; the rest (those 

 of the disk) are regularly gamo- 

 petalons, tubular, and five-Iobed 

 at summit; but they are small 

 and individually inconspicuous,

the involucre. B"t ™ Asters, Daisies, Golden- 



rods, and the like, these ray flowers 

 are pistillate and fertile, serving therefore for seed bearing as well 

 as for show. 



270. The Stamens. — First as regards their hisertion, or place of 

 attachment. 



The stamens usually go with the petals rather than with the pistil, 

 when adherent to either. Not rarely they are 



Epipetalotis, that is, inserted on (or adnate to) the corolla, as 

 in Fig. 171. When free from the corolla, they may be 



Hypogi/nous, inserted on the receptacle under 

 the pistil or gynceciirm. 



Perigynous, inserted on the calyx, that is, 

 with the lower part of filament adnate to the 

 calyx tube. 



Epif/ynoiis, borne apparently on the top of the 

 ovary; all which is shown in Figs. 182-1 S6. 



Gynandrous is another term relating to inser- 

 tion of rarer occurrence, tliat is, where the sta- 

 mens are inserted on (in other ^^■ords, adnate to) 

 the style, as in I^ady's Slipper (Fig. 207), and in 

 the Orchis family generally. 



271. In relation to each other, stamens are 

 more commonly 



Distinct, that is, without any union with each 

 other. But when united, the follow"ing tech- 

 nical terms of long use indicate their modes of 

 mutual connection : —
