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 tlieir 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 tlieir 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.
