Carissa spinarum, A. D.C. Flowers white, abundantly honied 
and fragrant ; tube 8 mm. long. Ina very young bud the closed 
stigmas lie below the ition: at the opening of the flower they 
are close to them, and receive the shed pollen onto the ring brush of 
hairs which they possess. Visiting insects brush off this pollen, 
and crawling insects are excluded from access to the honey by the 
hairs lining the corolla-tube. Visitors. HYMENOPTERA.

terandrous, the anthers touching one another in a little group over 
the stigmas ; later the filaments move out to the walls of the corolla 
tube, and place the anthers at the rim of the mouth of the corolla,
