Hijdropluil 11)11 apiicndiculitni Miclix. is proteranclrous. When the 

 floAver flrst comes into bloom the pistil is about one-half the length of the 

 mature stamens. The dehiscing anthers are gray with pollen, which dis- 

 appears within six hours. By the time the pollen is gone the pistil has 

 grown to the same length as the stamens, the two lobes of the stigma are 

 recurved and ready for ei'oss-poUenation. Bees are the pollen carriers, 

 which they get from the anthers of flowers that bloom at irregular hours 

 throughout the day. A plant in my yard began to bloom early in ^Nlay 

 and was still producing a few flowers August Sth. During dry weather 

 in Jidy, the flowers were less than oue-luilf the normal size, the tube 

 very much shortened, and in others the corolla changed from campanulate 

 to rotate. 



rolemoiuioii reptcnis L. The stamens are not as long as the pistil. 

 Dehiscence begins wlien the corolla is about half open, and before the 

 lobes of the stigma are re<nirved. Later the stamens are bent outward and 

 the pistils left to occupy the center fleld. Honey-bees enter the half- 

 blown flowers and come out well dusted with pollen, which they carry to 

 the older flowers. Invariably, when a bee comes to a plant, it pays its 

 respects flrst to the half-blown flower, and may not visit the older ones at 

 all. It seems to know that they liave been exhausted of nectar. As it en- 

 ters the slenderly supported flower it clasps all tlie organs at once, and its 

 movements are al)out as gracefid as those of the humble-bee.

 when the flowers first open are sharply curved to one side by a bend 

 near tlie middle of the style. After the anthers have shed their pollen 

 the pistil is erected and the stigma in position for cross-fertilization by 

 the insect-visitor. That this may be accomplished, the blooms last for 

 seieral days. 



The stiimatic lobes of Salilxit'ni (iiii/iihiris (I.. I Piirsh. are as long or 

 longer than the supporting style and the whole pistil only aboiit one half 

 the length of the stamens when the flower first opens. To make it 

 doubly sure that self-pollenation shall not occur, the lobes are closely 

 twisted together until the coiled anthers have unrolled and shed their 

 pollen. In the meantime the pistil has increased in length and the lol)es 

 curved back at right angles to the style. The lobes are stigmatic along 

 the inner side, and remained twisted after they are recurved, so that an 

 Insect passing over or under them with pollen on its back or under parts, 

 would be likely to effect fertilization. Many of the flowers are in bloom
