done, and tlie belief of this may save a needless panic and nncallcd-for rise in the price of corn. — J. Boswell Syme.

��Tmpatiens fulva in Kent. — I am not aware that Imjmtlens f/ilva has ever been recorded for the above comity, so it may be worth while noting that it is, and has been for at least eight years, extremely abun- dant on both sides of the little river Ravensbourne, near Lower Syden- ham. I have more than once walked along the stream for a considerable distance without losing sight of the plant. — James Britten.

��Specimens of each have come under my notice while looking through a portion of the herbarium of the Marlborougli College Natural History Society; Camelina satlva maybe added to the list of casuals. — James Britten.

��Winter Fertilization. — In the first number of ' Nature' (for Nov. 4th, 1869), I ventured a hypothesis, founded on a series of observations, that plants which flower in the winter have their reproductive organs specially arranged to promote self-fertilization. The following fact seems to confirm this theory : — I recently came upon a late-flowering patch of Sldluria aqiiatica, Scop., on which the following observations were made on two separate occasions, Oct. 21st and 28th. Plants belonging to the Order CaryopJiyllacece are, as a rule, so strongly protandrous (see my paper in the ' Journal of Botany' for October, 1870), that cross-fertiliza- tion is almost essential. In the present instance, however, I found in almost all the open flowers, of which there were a considerable number, the anthers discharging their pollen at the time when the stigma was receptive, the stigraatic surfaces being brought into immediate contact with the dehiscing anthers in a singular manner. Of the ten stamens five are opposite the petals, while five spring from interpetalar glands. The former rested nearly horizontally on the petals ; the latter, structurally the
