The Helleborea are herbaceous Ranunculacea:, with radical or alternate leaves, imbricate aestivation, petals either absent or irregular, 2-lipped or nectariferous. The sepals petaloid, the carpels mostly definite, capsular, dehiscent, sometimes connate and many-seeded. (3782.) The Ranunculacea? are in general poisonous plants, as remarkable for the acridity of their juices and venomous properties as for the beauty of their flowers. The principle upon which their deleterious powers depends is, according to the observation of Krappen, of a very singular nature. It is so volatile, that in most cases simple drying or infusion in water, or decoction, is sufficient to remove it, and to render the plants innocuous; and in some it is developed in such small quantities as not to be injurious. It is said to be neither acid nor alkaline, but its activity is increased by the addition of acids, or the admixture of sugar, honey, wine, spirit, &c, and that it is only removed or effectually destroyed by the agency of water.
