338 HYPECOUM 



Hypecoum Tourn. ex L. Papaveraceae (i). \i Medit. , Cent. As. FL 

 2-merous throughout. The inner petals are 3-sect, and the middle 

 lobe stands erect and encloses the sta. (if. Eichler, Bliithendia- 

 gramme). In H. procumbens L. the pollen is shed in the bud into 

 pockets on the inner surface of the inner petals, which close up before 

 the stigma developes. When pressed by an insect the pockets open 

 and dust it with pollen. The stigma only ripens after it has grown 

 above the level of the pollen. Cult. orn. fl.

Hypericum Tourn. ex L. Guttiferae (n). 220 temp, (i i Brit., St John's 

 wort, tutsan, &c.), nearly all perennial herbs with opp., often gland- 

 dotted 1. and cymes of fls., often forming pseudo-racemes or -umbels. 

 Sta. oo , united into 3 or 5 groups. Developmental study shows that 

 each of these groups arises as a simple papilla, and afterwards 

 branches ; a comparison with other Guttiferae however shows that in 

 H. we have more probably to do with a union of originally free sta. 

 The fls. contain no honey, but offer abundant pollen, and the larger 

 are frequently visited. They are homogamous, but the stigmas stick 

 out through the sta. and there is thus a chance of a cross.
