��SUPPLEMENT.

��To render the account of Rafflesir/ ArnoJdi more com- plete, I shall add the distinguishing characters of the order, tribes, genera and species of Baf/lesiacea with which I am acquainted. These characters, which form the chief part of the present supplement, as well as the notes to the original communication, have been written since November last.

The paper itself is printed as it was read in June 183 '4, a very few slight alterations, and those chiefly verbal, ex- cepted.^

"June 17. — A paper was read 'On the Eemale Flower and Fruit of Itaffiesia, with Observations on its Affinities, and on the Structure of Hi/chiora' By Robert Brown, Esq., Y.P.L.S.

"The author's principal object in this paper is to complete his account of Uafflesia Arnoldi, the male flower of which he described in a former communi- cation, published in the l^th volume of the Society's Transactions; and, iu connection with the question of its place in a natural arrangement, ho intro- duces a more detailed descri})tion and figures of Hijdnora ufricana, than have liilherto been given. The drawings of JRafflesia which accompany the paper are by Francis Bauer, Esq., and those of Ibjdnora by the late Mr. Ferdinand Bauer.

"From a comparison of Rafflesia with Bydnom and Cyiinus, he is confirmed in the opinion expressed in his former paper, but founded on less satisfactory evidence, that these three genera (to which Brugmansia of Blume is now to be added), notwithstanding several remarkable peculiarities in each, may all be referred to the same natural family ; and this famil}^ named by him Rajiesiacea, he continues to regard as being most nearly allied to Amrhice.

" He does not, however, admit an arrangement lately proposed by M. Endlicher, and adopted by Mr. Lindley, by whom these genera are included in the same natural class with BalanopJwrea of Richard ; an approximation founded on their agreement in the structure of embryo, and on the assumed absence of spiral vessels. On this subject he remarks, that in having a homo- geneous or acotyledonous embryo, they essentially accord, not only with many other plants, parasitical on roots, which it has never been proposed to unite with tliem, as Orohanrhe, &c., but also with OrcUdece^ their association with which would be still more paradoxical. And with respect to the supposed peculiarity in their vascular structure, he states that he has found spiral vessels not only in BaftJma (in which he had formerly denied their existence), and in Jdydiiora and Cythnts, but likewise in all the Balanophorece examined by him, particularly Cynoiucrinm and Ilclosis, as Dr. von Martius had long since done in Laiiffsdorfia, and Professor Meyer very recently in Hydnora.
