[A2]
Galium (yellow) cruciatum May 11.─ 62 Dimorphism
Pollen of male flowers of same diameter (but apparently more bad grains) as in the Hermaphrodite flowers
(viz 6/7000 of an inch) & the grain of both see good.─ The male flowers abound in lower part of plant, so pollen must be carried upwards or be wasted.
