    {From the Annals and Magazine of Natural History/or September 1854.] ON THE OCCURRENCE OF CINCHONACEOUS GLANDS IN GALTACEJE, AND ON THE RELATIONS OF THAT ORDER TO CINCHONACE^. By GEORGE LAWSON, F.R.P.S., F.B.S.E., Demonstrator of Botanj' and Vegetable Histology to the University of Edinburgh. [With a Plate.] A FEW years ago, Dr. Weddell of Paris, in his magnificent mono- gi'aph of the Cinchonas*, drew attention to a singular feature in these plants, viz. the constant presence of peculiar glands on their interpetiolar stipules; and the attention of this Society was called by Professor Balfour to Dr. WeddelFs observations. The inner faces of the stipules are in many cases firmly glued to the terminal bud, which they embrace, by a gummy or gum- resinous matter exuded by the small sessile glands to which reference has been made. This secretion is stated by Dr. Wed- dell to be fluid and transparent in Cinchonas and Cascarillas, but solid and opake in several other genera, remarkably so in Pimentelia glomerata. In the genus Rondeletia it is soft like wax, and of a beautiful green colour. The inhabitants of Peru, who give it the name of Aceite-Maria (oil of Mary), carefully collect it, and employ it as an external application in various maladies. It is well known to horticulturists that Cinchonaceous plants under cultivation are very liable to the attacks of Acarida and other parasites; and Mr. M'Nab has drawn my attention to the fact, that it is invariably in the neighbourhood of the stipules on the young shoots that these pests are most abundant, viz. at the points of the plant where the secretion is most copiously given off. * Histoire Naturelle dcs Quinquinas, ou Monographic du genre Cinchona, suivie d'unc Description du genre Cascnrilla et dc quekiues autres plantes de la mfime tribu, par M.
