382 Mr. J. E. Tcschemacher on a new species 



on examination appeared to differ essentially from the species 

 hitherto described from Java and Sumatra, I beg to offer to 

 the Society the following account, with a drawing. 



The specimens were gathered in Basei, a district of the pro- 

 vince of Leite, on the same spot visited by Mr. Cuming for 

 the purpose of finding this plant, during his late excursion to 

 the Philippine Islands. Not having seen any description of 

 this plant by him in the scientific journals, I am uncertain of 

 the result of his visit ; and although I propose the specific 

 name of Manillana for this species, I would readily yield it to 

 any other he may wish it to retain. 



The only accounts of Rafflesia to which I have access are, 

 that of R. Arnoldi from Sumatra, in the 13th volume of the 

 6 Transactions of the Linnean Society of London/ and that 

 given by Sir W. J. Hooker in the e Companion to the Botanical 

 Magazine/ of R. Patma, detected by Dr. Blume in Noussa 

 Kambangan, a small island on the coast of Java, and described 

 and figured by him in the c Flora Javae/ 



The column of one of my specimens was sent by itself from 

 Manilla, and of two others I have dissected buds ; the larger 

 by a vertical cut, the section shown in the figure ; the second, 

 a smaller specimen, by the removal of the whole of the enve- 

 lopes, exhibiting the naked column with its processes, edge, 

 anthers, &c. The column from Manilla, being dissected when 

 fresh, was considerably dried when placed in spirits. Its form 

 and several parts are therefore not very distinctly retained, 

 but the number of anthers and several other particulars are 

 clear enough. 



The largest bud of those I dissected is two and a half 

 inches in diameter, and arises from a cup three-fourths of an 

 inch in depth, the outer part of which is formed of the same 

 substance as the external bark of the root on which it is pa- 

 rasitic, and w T hich is evidently of the same structure as that 

 of the root of Cissus angustifolia, on which the R. Arnoldi was 

 found. 



It is probable that the smaller size alone would sufficiently 

 distinguish this from the last-mentioned species, the buds of 

 which are stated to be one foot in diameter, because, although 

 the respective age of these buds is not known, yet every part 

 is so perfect in the buds I dissected, even to minute and glan- 

 dular hairs, that it is not probable they would have been long 

 in this state before opening. 



There are apparently in this, five series of bracteae ; the 

 middle one, at its origin, about three-eighths of an inch in 

 thickness, or three times the thickness of the two outer and 

 the two inner series. These bracteae are imbricated over, and
