283. Insertion, or place of attaclimeut. The stamens usually go with 

 tlic; petals. Not rarely tliey are at base 



Epipetalons, that is, inserted 

 on (or adnate to) the corolla, as 

 in Fig. 283. Wlieu free from 

 the corolla, they may be 



Hijpogynoas, inserted on the 

 receptacle under the i)istil or 

 gynoecium. 



Perigijiwm, inserted on the 

 ealyx, that is, with the lower 

 part of filament adnate to the 

 calyx-tube. 



Epigynous, borne apparently on the top of the ovary ; all which is ex- 

 plained in Fig. 270-274. 



Gi/nandrous is another term relating to insertion of rarer occurrence, 

 that is, where the stamens are 

 inserted on (in otiier words, 

 adnate to) the style, as in 

 Lady's Slipper (Fig. 284), and 

 in the Orchis family generally. 

 283. In Relation to each 

 Other, stamens are more com- 

 monly 



Distinct, that is, without any 

 union with each other. But 

 wiien united, the following 

 technical terms of long use 

 's of mutual connection : — 

 Monudelphotis (from two Greek words, meaning 

 when united by their filaments into one set, usually into a ring or cup 

 below, or into a tube, as in the Mallow Family (Fig. 286), the Passion- 

 fiower (Fig. 260), the Lupine (Fig. 287), and in Lobelia (Fig 285). 



Diadclii/ioiis (moaning in two brotherhoods), when united by the fila- 

 ments into two sets, as in the Pea and most of its near relatives (Fig. 288), 

 usually nine in one set, and one in the other. 



Triaddphous{[\\vcc brotherhoods), wlien the filaments are united in three 

 sets or clusters, as in most species of Hypericum. 



" in one brotherhood "), 



Fig. 283. Corolla of Morning Glory laid open, to show the five stamens inserted 

 on it, near the base. 



Fig. 284. Style of a Lady's Slipper (Cypripediuni), and stamens united with it ; 

 a, a, the anthers of the two good stamens ; st, an abortive stamen, what should 

 be its antlier changed into a petal-like body ; stig, the stigma. 



Fui. 28."). Flowi'iof T.,obelia canlinalis, Cardinal llowur; corolla making ajiproach 

 to the ligulatc form; tilamcnts (.-0 ninnadclphous, and anthers {a) syngenesious.
