Stigmas and Upper Portion of the Style of Bagged Flowers of Pima Cotton. These parts dissected at about 3 p. m. of the day of anthesis from flowers which had been bagged to exclude insects, show the locus of automatic deposition of self pollen. The position of the lowest pollen grains indicates the height to which the sheath of the staminal column extended. The upper half of the stigmas is entirely free from pollen. (Magnified 10 times.)
