218 BOTANICAL INFORMATION. 
visit to Leyden, induces me to send the following particulars respecting 
the discovery of a new Raflesia, which grows in the Dutch East 
Indian Colonies. We owe the detection of this interesting plant to 
MM. Teysman, the head gardener, and Binnendijk, the second gar- 
dener, at Bintenzorg. . 
The new species, Rafflesia Rochussenii, so called after the late Governor- 
General of Java, J. V. Rochussen, is, like its congeners, a parasite. 
It grows on a Cissus, the C. serrulatus of Roxburgh, and was found at 
the foot of the Manellawangi, a mountain-chain, extending from the 
Panzzerango to Salak, and above the line of coffee-plantations named 
Pondok Tjatting. The exact locality is to the west of the tea-plan- 
tations which belong to Count Van den Bosch, and which form part 
of his estate, called Tjawi. - 
Several specimens were dug up, and transplanted, together with the 
Cissus to which they were attached, into the Royal Gardens, where the 
Raflesia developed itself and produced its flowers. The following 
account will show the difference between this new species and those 
already described. And first comes 
Raflesia Arnoldi, Br. This species is the most beautiful and largest 
of all. It was detected in 1848 by Dr. Arnold, in Sumatra, and living 
plants of it are shortly expected in the Botanical Gardens of Binten- 
zorg. The central column is furnished with from forty to sixty irre- 
gular processes, which are divided at the points (see Transactions of 
the Linnean Society, vol. xiii. t. 20) and covered with hairs (vol. xix. 
t.22). The interior surface of the perianth is moreover beset with 
thick glandular hairs. We may judge of the difference of size, for the 
bud of R. Arnoldi measures about twelve inches and a half in diameter, 
and that of R. Patma, Bl., thirteen inches and a half.* 
The R. Patma, Bl., is finely figured in Professor Blume’s ‘ Flora 
Javæ. Living plants of it may be seen in the Gardens of Bintenzorg, 
where they have twice flowered. The first blossom expanded in March, 
and the second in October, 1850. The colour of these flowers differed 
considerably from those represented in the * Flora Jayæ ; for the pro- 
cesses were pale, nearly flesh-coloured, while the annulus and lobes, 
on the first day of expansion, were of a light rose-colour: the warts, 
moreover, which exist on these parts, are not so regular in size. The 
margin of the perianth appears, in the delineation, to be elevated above 
* The buds of R. Patma, as figured in Blume's * Flora Javee,’ Tab. I., measure 
seven inches and a half in diameter.—Ep.
