In some specimens sent me from Mentone by Mr. Moggridge, together with the accompanying sketches, the anthers of the Fig. Hermaphrodite. Females. Thymus vulgabis (magnified). female, though small, were well formed, but they con^ tained very little pollen, and not a single sound grain could be detected. Eighteen seedliags were raised from purchased seed, sown in the same small bed; and these consisted of seven hermaphrodites and eleven females.
